Chapter 1# Introduction to Spring Boot

I started in Struts in 2003, Hibernate in 2004 and Spring 1.2 in 2005. It is almost 13 years Spring

released. It underwent various additions in modules and various releases. The first version of Spring

is written by Rod Johnson.

o Scheduler

� Spring Security (Authentication & Authorization)

o Standards, Protocols, Tools (Acegi Security)

� Convention over Configuration

o Spring Boot

� Spring Boot is a Convention over Configuration for solution for creating

stand-alone, production-grade spring-based applications that you can just-

run. It is pre configured with the Spring’s “opinionated view” of the best

configuration and use of the Spring platform and third party libraries so you

can “Get started with minimum effort”.

5

Convention over Configuration (Coding by Convention) is a software

paradigm used by the software frameworks that attempt to decrease the

number of decisions that a developer using the framework is required to

make without necessarily losing flexibility. The phrase essentially means a

developer only needs to specify unconventional aspects f the application. Fr

example if there is a class Sales in the model, the corresponding table in the

database is called “sales” by default.

If framework is Opinionated, it locks or guides you into their way of doing

things. PERL, PHP .net are Un-opinionated softwares.

� Most Spring Boot applications need very little Spring Configuration. Features

include:

• Creates stand-alone Spring applications.

• Embedded Tomcat or Jetty directly (no need to deploy WAR files).

• Provide opinionated starter POM (Project Object Models) to simplify

your Maven Configuration.

• Automatically configure Spring whenever possible.

• Provide production-ready features such as metrics, health checks

and externalized configuration.

• Absolutely no code generation and no requirement for XML

configuration.

o Spring Roo

� A Rapid Application Development solution for Spring based enterprise

applications.

� Spring Roo provides an alternative, code-generation based approach at

using convention-over-configuration to rapidly build applications in Java. It

currently supports Spring Framework, Spring Security and Spring Web Flow.

� Spring Transaction Management

o Support of Programmatic, Declarative, Schema based and Annotation based TX

management for Local and Distributed TX management.

� Spring Testing

o Supports classes for writing Unit Testing and Integration Testing

� Spring Integration Framework

o Spring Integration is a framework for Enterprise Application Integration that

provides reusable functions essential to messaging or event-driven architectures.

� Routers – routes a message to a message channel based on conditions.

� Transformers – Converts/Transforms/Changes the message payload and

creates a new message with transformed payload.

� Adapters – To integrate with other technologies and systems (HTTP, AMQ

(Advanced Message Queuing), JMS, XMPP (eXtensible Messaging and

Presence Protocol), SMTP (Simple Mail Transfer Protocol), IMAP (Internet

Message Access Protocol), FTP (File Transfer Protocol) as well as FTPS/SFTP

file systems etc).

� Filters – Filters a message based on criteria. If the criteria are not met, the

message is dropped.

� Service Activators – Invoke an operation on a service object.

6

� Management and Auditing

o Spring Integration supports pipes-and-filter based Architectural Pattern. - POSA

� Spring Batch Framework

o Spring Batch is a framework for batch processing that provides reusable functions

that are essential in processing large volumes of records, including:

� Logging/Tracing

� Transaction Management

� Job Processing Statistics

� Job Restart

o Execution of series of extremely high-volume, high-performance batch Jobs through

optimizations and partitioning techniques. Each step consists of READ-PROCESS-

WRITE task or single operation task (tasklet).

o The READ-PROCESS-WRITE process consists of these steps: “read data” from a

resource (comma separated values – CSV, XML or database), “process it” and then

write it to other resources (CSV, XML, DB). Spring Batch provides many classes to

read/write CSV, XML, Data base.

Spring Boot

Is Spring Boot replacement to Spring Framework?

� No Spring Boot is new way to create Spring application with ease of development and use.

� It makes easy to create a production-ready Spring based applications that you can just-run.

� You can create standalone applications that use an embedded server, making them 100%

runnable applications.

� Spring is a Opinionated technology in that it will help you follow the best practices for

creating robust, extensible and scalable Spring applications.

You can find Spring Boot Project at http://projects.spring.io/spring-boot and its extensive

documentation is available at http://projects.spring.io/spring-

boot/doc/current/reference/htmlsingle.

Spring Applications

If you are a Java Web Application Developer you know how to create a simple web application isn’t.

The steps are:

Create a Web Application Directory Structure:

Webapp1

.html, .css .js, .jpg

WEB-INF

web.xml (configure DispatcherServlet here)

9

disp-servlet.xml (disp is the name of the servlet-name of DispatcherServlet)

classes

Place user defined .class files

lib

Place 3rd

party jar files

The way to make .war file and to deploy it into web server/application server is using:

• jar –cvf WebApp1.war *.html *.css *.js *.jpg WEB-INF

• Apache ANT

• Apache Maven

• Gradle

The Web Server/Application Servers are:

• Tomcat

• JBoss

• WebLogic

• WebSphere

But building (creating directory structure, compile classes, placing files in respective folder making

war) and deploying web application using above said options is painful to developer. Isn’t it?

Hence use tools/IDEs like STS (Spring Tool Suite), YEOMAN etc.

Though we use tools like STS we need to add dependencies in Maven pom.xml file if we want to use

additional services like Persistence, Messaging, Security, Logging, Validators etc. Then during

pom.xml file execution all the dependent jar files are included in our project. Even adding

dependencies in pom.xml file by developer is an additional effort.

Then what is the best solution that automatically creates directory structure, placing files in

respective folders, download all the service required dependent jar files, compile java classes,

make war and to deploy it into web server/ application server.

Yes. You got the Answer. The hero of our current topic Spring Boot.

Instead of reading more about Spring Boot and how it is easy to use it, take a look at simple Spring

web application.

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication

public class SimpleWebApp {

public static void main(String[] args) {

SpringApplication.run(SimpleWebApp.class, args);

}

}

Shows the entry point for a Spring Boot Application in Java. It’s using SpringBootApplication

annotation and the SpringApplication singleton class in the main method that will execute the

application. The run method accepts two arguments – the class that actually contains the annotated

@SpringBootApplication and the application’s arguments.

10

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

@RestController

public class SimpleWebController {

@RequestMapping("/")

public String greetings(){

return "<h1> Spring Boot Rocks in Java too!</h1>";

}

}

Shows you the typical Spring Web MVC Controller class, where you use the @RestController and

@RequestMapping annotations to tell Spring to use the SimpeWebController class as a web controller

and to use the method greetings as an entry point for a HTTP request. You can run this example by

using Spring CLI.

E:\active\spring 4.4\boot applications> spring run *.java

Note: The Spring CLI installation, how to use STS to run the application will be covered in the next

Chapter.

Spring Boot Features:

� The SpringApplication singleton class acts as a Spring Boot application by calling run()

method.

� Spring Boot allows you to create a applications without requiring any XML configuration.

Spring Boot doesn’t generate code.

� Spring Boot provides a fluent builder API through the SpringApplicationBuilder singleton class

that allows you to create hierarchies with multiple application contexts.

� Spring Boot offers you more ways to configure the Spring application events and listeners.

� As discussed earlier Spring is an Opinionated technology which means the spring boot will

attempt to create the right type of application, either a web application (embedding Tomcat

or Jetty Container) or a single application.

� The ApplicationArguments interface allows you to accept any number of arguments. This is

useful when we want to run your application with some parameters. For example we can use

-- debug mylog.txt or -- audit=true and have access to those values.

� Spring Boot allows you to execute code after the application has started. The only thing you

need to do is implement the CommandLineRunner interface and provide the implementation

of the run(String... args) method.

� Spring Boot allows you to externalize configurations by using an application.properties or

application.yaml file.

� You can add administration-related features, normally through JMX. You can do this simply by

enabling the spring.application.admin.enabled property in application.properties file.

� Spring Boot allows you to have profiles that will help your application run in different

environments.

� Spring Boot allows you to configure and use logging very simply.

� Spring Boot provides a simple way to configure and manage your dependencies by using

starter poms. In other words if you are going to create a web application you only need to

include the spring-boot-start-web dependency in your Maven POM or Gradle build file.

� Spring Boot provides out-of-the-box on-functional requirements by using the Spring Boot

Actuator, so you can see the health memory and so on, of your application.

11

� Spring Boot provides @Enable<feature> annotations that help you to include, configure and

use technologies like (SQL and NoSQL), caching, scheduling, messaging, spring Integration,

batching and more.

12

Chapter 2# Your First Spring Boot Application

You can create Spring Boot Applications by using the Spring Boot Command Line Interface or by using

Maven, Gradle, Apache ANT or STS.

Installing Spring Boot CLI

Before installing Spring Boot CLI we need to check JDK is installed or not, java PATH and CLASSPATH

are updated or not, JAVA_HOME environment variable is set or not”. After that you must down

following .zip file from internet.

• https://repo.spring.io/release/org/springframework/boot/spring-boot-

cli/1.4.2.RELEASE/spring-boot-cli-1.4.2.RELEASE-bin.zip

• Extract zip file into local directory structure.

• Create SPRING_HOME environment variable up to spring-boot-cli installation directory of

extracted folder.

• Update PATH environment variable also up to bin directory of extracted folder.

• Update CLASSPATH environment variable up to extracted lib directory \ (back slash) spring-

boot-cli-1.4.2.RELEASE.jar

Run the following command in above classes placed directory:

E:\active\spring 4.4\boot applications> spring run *.java

Suppose if you want to create a base or minimal project:

E:\active\spring 4.4\boot applications> spring init - - build maven demo

This command will call the web service at https://start.spring.io and will create a folder named demo.

demo/

-.gitignore

-mvnw

-mvnw.cmd

-pomxml

Above diagram shows Spring Boot Project directory structure created when you execute spring init

command. If you want to add more features such as web, JPA, and Maven Projects - you can execute

following command:

spring init –dweb,data-jpa,h2,thymeleaf - - build maven demo1 - - force

The above command creates Spring Boot Maven Project and will include all the necessary

dependencies in pom.xml file. The last - -force overrides the previous demo directory or you can

change the name.

Spring Boot with Maven

If you already use Maven then we can Jump start with Spring Boot applications.

Using Maven

Below file shows the pom.xml file that you use every time you need to create a Spring Boot app.

pom.xml

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

http://maven.apache.org/xsd/maven-4.0.0.xsd">

<modelVersion>4.0.0</modelVersion>

<groupId>com.example</groupId>

<artifactId>demo</artifactId>

<version>0.0.1-SNAPSHOT</version>



<parent>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-parent</artifactId>

<version>1.3.1.RELEASE</version>

</parent>



<dependency>


<artifactId>spring-boot-starter</artifactId>

</dependency>



<build>

<plugins>

<plugin>


<artifactId>spring-boot-maven-plugin</artifactId>

</plugin>

</plugins>

14

</build>

</project>

• If you take a closer look at parent tag section you need to include spring-boot-starter-parent

artifact. This dependency includes all you need to run you application such as spring-core,

spring-test.

• Another section is starter poms in this we will include other dependencies required such as

for web application



<dependencies>

<dependency>


<artifactId>spring-boot-starter-web</artifactId>

</dependency>

</dependencies>

This dependency includes spring-core, spring-web, spring-webmvc, embedded tomcat web server and

other libraries required to build web application.

Spring Boot using External Tools

Spring Boot using the Spring Initializr:

To get the above we page just type http://start.spring.io url on the browser

15

The above interface shows where you can create your Spring Boot Application. You can include all the

dependencies using by just typing web, security, jpa. If you click Generate Project button, you will get

a zip file that contains the structure of the pom.xml file.

Notice: Click on switch to the full version hyperlink to see more options and all the Spring Boot

dependences, check required checkboxes and click on Generate Project.

Spring Boot using the “Spring Tool Suite”/STS:

STS is a eclipse based IDE bundled with Spring projects capability Neither we can include STS plugin to

Eclipse nor we can download STS from https://spring.io/tools/all.

Download the Windows ZIP file, extract it, in the installation directory you will find sts.exe file. Now

you must see File-> New-> the Spring Starter Project option.

16

You can see the Spring Starter Project wizard

App: Creating an Spring Boot JdbcTemplate Application

17

Click on Finish

The project directory structure looks as below:

18

I added following files to run JdbcTemplate Application:

First of all we need to update pom.xml







19


<artifactId>simple-jdbc-app</artifactId>


<packaging>jar</packaging>

<name>jdbc</name>

<description>Demo project for Spring Boot</description>

<parent>




<relativePath /> 

</parent>

<properties>

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

<project.reporting.outputEncoding>UTF-

<scope>test</scope>

</dependency>

</dependencies>

<build>

<plugins>

<plugin>



</plugin>

</plugins>

</build>

</project>

Then we will add properties in src/main/resources/application.properties

spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver

spring.datasource.url=jdbc:oracle:thin:@localhost:1521:XE

spring.datasource.username=active

spring.datasource.password=activenet

Followed by we will add Java Bean/@Entity class to the project

package com.example.spring;

import java.text.SimpleDateFormat;

import java.util.Date;

public class Journal {

private Long id;

20

private String title;

private Date created;

private String summary;

private SimpleDateFormat format = new SimpleDateFormat("MM/dd/yyyy");

public Journal(Long id, String title, String summary, Date date) {

this.id = id;

this.title = title;

this.summary = summary;

this.created = date;

}

Journal() {

}

public Long getId() {

return id;

}

public void setId(Long id) {

this.id = id;

}

public String getTitle() {

return title;

}

public void setTitle(String title) {

this.title = title;

}

public Date getCreated() {

return created;

}

public void setCreated(Date created) {

this.created = created;

}

public String getSummary() {

return summary;

}

public void setSummary(String summary) {


}

public String getCreatedAsShort() {

return format.format(created);

}

21

public String toString() {

StringBuilder value = new StringBuilder("* JournalEntry(");

value.append("Id: ");

value.append(id);

value.append(",Title: ");

value.append(title);

value.append(",Summary: ");

value.append(summary);

value.append(",Created: ");

value.append(getCreatedAsShort());

value.append(")");

return value.toString();

}

}

Then we will create JournalService class


import java.util.ArrayList;


import java.util.List;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.jdbc.core.JdbcTemplate;

import org.springframework.stereotype.Service;

@Service

public class JournalService {

private static final Logger log =

LoggerFactory.getLogger(JournalService.class);

@Autowired

JdbcTemplate jdbcTemplate;

public void insertData(){

log.info("> Table creation");

jdbcTemplate.execute("CREATE TABLE JOURNAL(id number, title

VARCHAR2(255), summary VARCHAR2(255), created DATE)");

log.info("> Inserting data...");

jdbcTemplate.execute("INSERT INTO JOURNAL(id,title,summary,created)

VALUES(5, 'Get to know Spring Boot','Today I will learn Spring Boot','01-Jan-

2018')");


VALUES(6, 'Simple Spring Boot Project','I will do my first Spring Boot

project','01-Jan-2018')");


VALUES(7, 'Spring Boot Reading','Read more about Spring Boot', '01-Jan-2018')");


VALUES(8, 'Spring Boot in the Cloud','Learn Spring Boot using Cloud Foundry','01-

Jan-2018')");

22

log.info("> Done.");

}

public List<Journal> findAll() {

List<Journal> entries = new ArrayList<>();

jdbcTemplate

.query("SELECT * FROM JOURNAL",

new Object[] {}, (rs, row) -> new

Journal(rs.getLong("id"), rs.getString("title"), rs.getString("summary"), new

Date(rs.getTimestamp("created").getTime()))).forEach(entry -> entries.add(entry));

return entries;

}

}

At last i will include one class called SimpleJdbcApplication





import org.springframework.boot.CommandLineRunner;




public class SimpleJdbcAppApplication implements CommandLineRunner {


LoggerFactory.getLogger(SimpleJdbcAppApplication.class);

@Autowired

JournalService service;


SpringApplication.run(SimpleJdbcAppApplication.class, args);

}

@Override

public void run(String... arg0) throws Exception {

log.info("@@ Inserting Data....");

service.insertData();

log.info("@@ findAll() call...");

service.findAll().forEach(entry -> log.info(entry.toString()));

}

}

Now right click on the SimpleJdbcApplication and run it as “Spring Boot

App”. We will notice table, creation record insertion, and records

retrieval on the console screen.

23

App: The next Example is on Spring, JPA, Web MVC to display all the list of

Journals

24

The directory structure looks like as follows:

25

pom.xml








<artifactId>simple-jpa-app</artifactId>



<name>spring-boot-jpa-journal</name>


<parent>




<relativePath /> 

</parent>

<properties>





</properties>

<dependency>



<scope>test</scope>

</dependency>

</dependencies>

<build>

<plugins>

<plugin>



</plugin>

</plugins>

</build>

</project>

26

The above is the pom.xml file. The important point is the dependencies section which contains all the

poms that you selected in the wizard.

� spring-boot-starter-web – ours is a web application

� spring-boot-starter-thymeleaf – a template engine

Chapter 3# Spring Boot Auto-Configuration, Features, and More

In this chapter we will see how Spring Boot features that involve configuration. Shows how

@EnableAutoConfiguration works, how to externalize configuration properties, enable and disable

features.

Auto Configuration

@SpringBootApplication inherits @EnableAutoConfiguration, @Configuration, @ComponentScan,

which is why we can use exclude parameter in @SpringBootApplication.



import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;

import

org.springframework.boot.autoconfigure.jms.activemq.ActiveMQAutoConfiguration;

@SpringBootApplication(exclude={ActiveMQAutoConfiguration.class,DataSourceAutoConf

iguration.class})

public class DemoApplication {


SpringApplication.run(DemoApplication.class, args);

}

}

On the command prompt we can type spring run DemoApplication.java - - debug

@EnableAutoConfiguration and @Enable<Technology> Annotations

You will find that in some of the Spring modules like Spring Core, Spring Data, Spring Security, Spring

AMQP, and Spring Integration provide @Enable<Technology> annotations. For example

@EnableTransactionManagement, @EnableRabbit, @EnableIntegration. Within Spring applications

we can use these annotations to follow the pattern “convention over configuration” thus makes

your apps even easier to develop and maintain without worrying too much about configuration.

Spring Boot can also take advantage of these annotations. These annotations are used in the

@EnableAutoConfiguration annotation to do the auto-configuration. Take a closer look

@EnableAutoConfiguration annotation to see the logic behind it. You will see where the

@Enable<Technology> annotation fit.

Chapter 4# Spring Boot CLI

The run command

The run command will allow you to run Java Spring Boot applications.

Syntax: spring run [options] <files> [--] ] [args]

Example: spring run WebApp.java

// WebApp.java

package com.apress.spring;





@RestController


public class WebApp {


public String greetings(){

return "Spring Boot Rocks in Java too!";

}


SpringApplication.run(WebApp.class, args);

}

}

The test command

The test command runs Spring Java tests.

Syntax: spring test [options] <files> [- -] ] [args]

Example: spring test MyTest.java

// MyTest.java

import org.junit.Rule;

import org.junit.Test;

import org.springframework.boot.test.OutputCapture;

import static org.hamcrest.Matchers.*;

import static org.junit.Assert.*;

public class MyTest {

@Rule

public OutputCapture capture = new OutputCapture();

@Test

public void stringTest() throws Exception {

System.out.println("Spring Boot Test works in Java too!");

assertThat(capture.toString(), containsString("Spring Boot Test

works in Java too!"));

}

}

32

The grab command

The grab command will download all the Spring Java dependencies to the ./repository directory.

Syntax: spring grab [options] <files> [- -] ] [args]

Example: spring grab MyTest.java

The jar command

The jar command will create a self contained executable JAR file.

Syntax: spring jar [options] <jar-name> <files>

Example: spring jar app.jar

java -jar app.jar

The war command

This is very similar to previous command. The war command will create a self contained executable

WAR file from Java Script.

Syntax: spring war [options] <war-name> <files>

Example: spring war app.war

java –jar app.war

The install command

The install command is very similar to grab command. The only difference is we need to specify the

library we want to install.

Syntax: spring install [options] <coordinates>

Example: spring install org.spockframework:spock-core:1.0-groovy-2.4

The uninstall command

The uninstall command uninstalls all the dependencies from the lib directory.

Syntax: spring uninstall [options] <coordinates>

Example: spring uninstall org.spockframework:spock-core:1.0-groovy-2.4

The init command

The init command will help you initialize a new project by using Spring Initializr without using IDE

Syntax: spring init [options] [location]

Example: shown in previous chapter

The shell command

The shell command will start an embedded shell.

Example: spring shell

33

The help command

Example: spring help init

34

Chapter 5# Spring with Spring Boot

• Spring Web MVC Applications

• Using Spring with Spring Boot

• Using Spring Technologies in Spring Boot

Spring Web MVC Applications

The Spring Framework brought a new way to develop web applications by introducing a MVC pattern

into the framework that is easy to setup and use. MVC first time termed by “Smalltalk” ( a

Programming Language) developer “Trygve Reenskaug” in Smalltalk-76. In 1980 “Jim Althoff” and

others implemented MVC library in Smalltalk-80 library for developing GUIs. Later supported and

promoted by “Kent Beck”. He is also a chief contributor of “eXtreme Programmng” also called as XP

software development methodology. He is also one of the 17 original signatories of “Agile

Development Methodology”.

MVC pattern subsequently evolved, giving raise to variants such as HMVC (Hierarchical MVC), MVA

(Model-View-Adapter), MVVM (Model-View-ViewModel) and other MVC adopted patterns.

Advantages of MVC are:

• Simultaneous development – Multiple developers can work simultaneously on the model,

controller and views

• High cohesion – MVC enables logical grouping related actions on a controller together.

• Low Coupling – The very nature of MVC is that there is low coupling among models, views,

controllers

• Ease of modification – Because of the separation of responsibilities, further development of

modifications is easier.

• Multiple views for a model – Models can have multiple views

Disadvantages of MVC are:

• Code navigability – The framework navigation can be complex because of introduces new

layers of abstraction and requires users to adapt to the composition criteria of MVC.

• Multi-artifact consistency – Decomposing a feature into three artifacts cause scattering. Thus

requiring developers to maintain the consistency of multiple representations at once.

• Pronounced learning curve – Knowledge on multiple technologies become the norm.

Developers using MVC need to be skilled in multiple technologies.

But the Spring team did an excellent job using this pattern as a base model for every web application

by simplifying its functionality.

Let’s look at Spring MVC application using Maven archetype;

mvn archetype:create –DgroupID=com.example.spring –DartifactId=simple-web-spring-

app –DarchetypeArtifcatId=maven-archetype-webapp

The above maven archetype is useful just for creating files and directory structure.

Type mvc clean package

We will have the target/simple-web-spring-app.war file. Now we can deploy this web application into

any favourite J2EE web server/application servers like Tomcat/WebLogic/WebSphere/JBoss. Start the

J2EE server and type URL as http://localhost:65535/smple-web-spring-app/showMessage.html.

If you already know Spring MVC, you may notice that the example we saw is a old way of doing it.

Spring version 2.5, 3, 4 allows you add annotations to avoid extending from other classes and have

more mapping in one single class. Below is the example of implementing Controller using

Annotations.

src/main/java/com/apress/spring/SimpleController.java using annotations


import org.springframework.stereotype.Controller;


import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.servlet.ModelAndView;

@Controller

@RequestMapping("/showMessage.html")

public class HelloWorldController{

@RequestMapping(method = RequestMethod.GET)

public ModelAndView helloWorld(){

ModelAndView model = new ModelAndView("showMessage");

model.addObject("message", "Spring MVC Web App with annotations");

return model;

}

}

src/main/webapp/WEB-INF/mvc-config.xml


<beans xmlns="http://www.springframework.org/schema/beans"


xmlns:mvc="http://www.springframework.org/schema/mvc"

xmlns:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="http://www.springframework.org/schema/mvc

http://www.springframework.org/schema/mvc/spring-mvc.xsd

<context:component-scan base-package="com.example.spring" />

<bean

class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<property name="prefix" value="/WEB-INF/view/"/>

<property name="suffix" value=".jsp"/>

</bean>

</beans>

Deploy and run this web application on any interested J2EE server and run from browser.

Now we create a simple Spring Boot Application

Create a directory for spring boot web project and type following Spring CLI command to

create a Spring Boot Project:

spring init –d=web –g=com.example.spring –a=simple-web-spring-boot –package-

name=com.example.spring –name=simple-web-spring-boot –x

Now the application directory structure looks as follows:

.

mvnw

mvnw.cmd

pom.xml

src

main

java

com

example

spring

SimpleWebSpringBootApplication.java

resources

application.properties

static

templates

test

java

com

example

spring

SimpleWebSpringBootApplicationTest.java

Now open SimpleWebSpringBootApplication.java class and modify as:

src/main/java/com/apress/spring/SimpleWebSpringBootApplication.java






@RestController


public class SimpleWebSpringBootApplication {

@RequestMapping("/showMessage.html")

public String index(){

39

return "Spring Boot Rocks!";

}


SpringApplication.run(SimpleWebSpringBootApplication.class, args);

}

}

Type spring-boot:run

import org.springframework.data.jpa.repository.config.EnableJpaAuditing;


@EnableJpaAuditing

public class EasyNotesApplication {


SpringApplication.run(EasyNotesApplication.class, args);

}

}

It contains a simple annotation called @SpringBootApplication which is a combination of the

following more specific spring annotations -

• @Configuration : Any class annotated with @Configuration annotation is bootstrapped by

Spring and is also considered as a source of other bean definitions.

• @EnableAutoConfiguration : This annotation tells Spring to automatically configure your

application based on the dependencies that you have added in the pom.xml file.

For example, If spring-data-jpa is in the classpath, then it automatically tries to configure

a DataSource by reading the database properties from application.properties file.

43

• @ComponentScan : It tells Spring to scan and bootstrap other components defined in the

current package (com.example.easynotes) and all the sub-packages.

The main() method calls Spring Boot’s SpringApplication.run() method to launch the application.

2. resources/

This directory, as the name suggests, is dedicated to all the static resources, templates and property

files.

• resources/static - contains static resources such as css, js and images.

• resources/templates - contains server-side templates which are rendered by Spring.

• resources/application.properties - This file is very important. It contains application-wide

properties. Spring reads the properties defined in this file to configure your application. You can

define server’s default port, server’s context path, database URLs etc, in this file.

You can refer this page for common application properties used in Spring Boot.

3. EasyNotesApplicationTests - Define unit and integration tests here.

4. pom.xml - contains all the project dependencies

Chapter 7# Data Access with Spring Boot

SQL Databases

Data Access using JdbcTemplate with Spring Boot

Data Access using JPA with Spring Boot

Note: the above JdbcTemplate example and JPA examples are covered in previous

chapter.

No SQL Databases

No SQLL Databases are another way to persist data, but in different way from the tabular

relationships of the relational databases. You can find it based on its data model.

• Column (Cassandra, HBase etc)

• Document (CouchDB, MongoDB etc)

• Key-Value (Redis, Riak etc)

• Graph (Neo4J, Virtuoso etc)

• Multi-model (Orient DB, ArangoDB etc)

As you can see we have many options. I think the most important kind of feature here nowadays is to

find a database that is scalable and can handle millions of records easily. In this section we will discuss

MongoDB a No SQL document database.

Install and run mongodb database. Download ZIP file from https://www.mongodb.org, extract zip file,

double click on C:\Program Files\MongoDB\Server\3.2\bin\mongod.exe

If you want to see the actual data in your MongoDB server, you can open terminal and execute the

following commands:

$ mongo

MongoDB shell version: 3.2.1

connecting to: test

> show collections

blog

journal

system.indexes

> db.journal.find()

{ "_id" : ObjectId("56b192d377c83f89cae51f5f"), "_class" :

"com.apress.spring.domain.

Journal", "title" : "Get to know Spring Boot", "created" : ISODate("2016-01-

02T07:00:00Z"),

"summary" : "Today I will learn Spring Boot" }

{ "_id" : ObjectId("56b192d377c83f89cae51f60"), "_class" :


Journal", "title" : "Simple Spring Boot Project", "created" : ISODate("2016-01-

03T07:00:00Z"), "summary" : "I will do my first Spring Boot Project" }



Journal", "title" : "Spring Boot Reading", "created" : ISODate("2016-02-

02T07:00:00Z"),

"summary" : "Read more about Spring Boot" }



Journal", "title" : "Spring Boot in the Cloud", "created" : ISODate("2016-03-

01T07:00:00Z"),

"summary" : "Spring Boot using Cloud Foundry" }

When you use the mongo client shell, you will be connected directly to the test database, which is

what Spring Boot will use as main database to create the document collection. In this case, it’s the

name of the Java class: journal . Then you can use the db.journal.find() query to get all the data.

Spring Boot allows you to define the name of your database if you don’t want to use the default one.

You only need to add the following property to the src/main/resources/application.properties file:

spring.data.mongodb.database=myjournal

Then the M ongoRepository w ill create the database using the m yjournal name and will create the

journal collection as well.

You can take a peek at the MongoDB server by using its client. You can see the database, the

collection, and the data with the following commands:

$ mongo

MongoDB shell version: 3.2.3

connecting to: test

> show databases;

local 0.078GB

Chapter 9# Security with Spring Boot



This chapter shows how to use Spring Security in Spring Boot Application in order to secure web

application. Web will learn “Basic Security” to “OAuth”. Security has become a primary and

important factor for desktop, web and mobile applications. Security is little hard to learn because we

need to learn “Cross Site Scripting”, “Authentication”, “Authorization”, “Secure Sessions”,

“Identification”, “Encryption” and lot more.

Spring security is centred around AuthenticationProvider and UserDetailService; it also provides

integration with Identity Service Provider Systems such as LDAP, Active Directory, Kerberos, PAM,

OAuth and so on.

Now lets run with mvnw spring-boot:run

After executing the command you should be able to see a new line about the

AuthenticationManagerConfiguration class. That shows something like as below:

...

INFO 29387 --- [] .e.DelegatingFilterProxyRegistrationBean : Mapping filter:

'springSecurityFilterChain' to: [/*]

INFO 29387 --- [] o.s.b.c.e.ServletRegistrationBean : Mapping servlet:

'dispatcherServlet' to [/]

INFO 29387 --- [] b.a.s.AuthenticationManagerConfiguration :

Using default security password: f3f818e9-a36f-48ca-9b44-5ed4b3224384

INFO 29387 --- [] o.s.s.web.DefaultSecurityFilterChain : Creating filter chain:

Ant [pattern='/css/**'], []

INFO 29387 --- [] o.s.s.web.DefaultSecurityFilterChain : Creating filter chain:

Ant [pattern='/js/**'], []

...

In the console, you should see the text: "Using default security password: xxx-xxxx-xxx ..." with a

GUID (Global Unique ID) that you will use to authenticate. If you go to your browser and visit

http://localhost:65535, you should see something similar to Figure given below.

62

Shows basic security window, fields are empty by default, enter user and password and submit. By

default AuthenticationManager interface implementation has a single username called user. So in

the username box enter username as user and password as GUID shown on the logs – a random

password. This example uses f3f818e9-a36f-48ca-9b44-5ed4b3224384 GUID. This GUID

changes every time when you run the application.

That’s it. That is the easiest and most basic security you can add to your web application ad the only

thing you did was add the spring-boot-starter-security pom. When Spring Boot app starts

the auto configuration will identify that you have the web and the security dependencies and it will

create the basic security authentication. Of course, this is not very useful with production apps.

Security using the application.properties file:

src/main/resources/application.properties

spring.datasource.url = jdbc:mysql://localhost:3306/journal

spring.datasource.username = springboot

spring.datasource.password = springboot

spring.datasource.testWhileIdle = true

spring.datasource.validationQuery = SELECT 1

spring.jpa.show-sql = true

spring.jpa.hibernate.ddl-auto = create-drop

spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

spring.data.rest.basePath=/api

# Security

security.user.name = springboot

security.user.password = isawesome

Now again run mvnw spring-boot:run and then access the application using

http://localhost:655535, enter username as springboot and password as isawesome and see the

result. You can use cURL to access your /api and make sure it is also secured with

On command prompt type: curl -i http://springboot:isawesome@locahost:65535/api

HTTP/1.1 200 OK

Server: Apache-Coyote/1.1

X-Content-Type-Options: nosniff

X-XSS-Protection: 1; mode=block

Cache-Control: no-cache, no-store, max-age=0, must-revalidate

Pragma: no-cache

Expires: 0

X-Frame-Options: DENY

Strict-Transport-Security: max-age=31536000 ; includeSubDomains

Content-Type: application/hal+json;charset=UTF-8

63

{

"_links" : {

"entry" : {

"href" : "http://localhost:8080/api/journal{?page,size,sort}",

"templated" : true

},

"profile" : {

"href" : "http://localhost:8080/api/profile"

}

}

}

Using this command, you can see that passing the username:password gives you access to the REST

API. You can stop your application now.

In-Memory Security

Using the application.properties file isn’t a real solution. Let’s see how you can use in-memory

security. You are going to create a new

src/main/java/com/example/spring/config/InMemorySecurityConfiguration.java file.

src/main/java/com/apress/spring/config/InMemorySecurityConfiguration.java

package com.example.spring.config;


import org.springframework.context.annotation.Configuration;

import org.springframework.security.config.annotation.authentication.builders.

AuthenticationManagerBuilder;

import

org.springframework.security.config.annotation.authentication.configuration.

EnableGlobalAuthentication;

@Configuration

@EnableGlobalAuthentication

public class InMemorySecurityConfiguration {

@Autowired

public void configureGlobal(AuthenticationManagerBuilder auth) throws

Exception {

auth.inMemoryAuthentication().withUser("user").password("password").

roles("USER")

.and().withUser("admin").password("password").

roles("USER", "ADMIN");

}

}

Below shows the InMemorySecurityConfiguration.java class . Let’s dig into it:

• @Configuration . This annotation tells the Spring Boot to use it as part of the configuration; it’s

similar to using XML files.

• @EnableGlobalAuthentication . This annotation marks the class and configures all the necessary

beans to activate the security on the application; it signals that the annotated class can be used to

configure a global instance of the AuthenticationManagerBuilder .

• @Autowired/configureGlobal(AuthenticationManagerBuilder auth) .

This method is called to auto-wire the AuthenticationManagerBuilder. The

AuthenticationManagerBuilder allows you to easily build your authentication by adding

UserDetailsService and the authentication providers. You are going to learn more about the options

64

in the following sections. In this case, it will use in-memory because it’s calling the

inMemoryAuthentication method and setting up two users with their passwords and roles.

Before you run the application, comment out the security.user.name and security.user.password

properties from the src/main/resources/application.properties file. Just add a # sign in front of

them, like this:

#security.user.name=springboot

#security.user.password=isawesome

Now you can run the journal app as usual:


Run this on browser using http://localhost:65535, enter username as “user”, password as

“password”.

Security using a Database

Using the in-memory isn’t a real solution either, but there are alternatives. How about using

a database? Normally this is one of the most common approaches to saving users. Let’s see

what you need to modify in order to use a database as a security mechanism.

You are using MySQL/Oracle as a database engine, so let’s continue using that. First you are

going to create a security configuration. Create the

src/main/java/example/spring/config/JdbcSecurityConfiguration.java file.

package com.example.spring.config;

import java.sql.ResultSet;



import org.springframework.context.annotation.Configuration;

import org.springframework.jdbc.core.JdbcTemplate;

import org.springframework.jdbc.core.RowMapper;

import org.springframework.security.config.annotation.authentication.builders.

AuthenticationManagerBuilder;

import

org.springframework.security.config.annotation.authentication.configuration.

EnableGlobalAuthentication;

import org.springframework.security.config.annotation.authentication.configurers.

GlobalAuthenticationConfigurerAdapter;

import org.springframework.security.core.authority.AuthorityUtils;

import org.springframework.security.core.userdetails.User;

import org.springframework.security.core.userdetails.UserDetailsService;

@Configuration

@EnableGlobalAuthentication

public class JdbcSecurityConfiguration extends

GlobalAuthenticationConfigurerAdapter{

@Bean

public UserDetailsService userDetailsService(JdbcTemplate jdbcTemplate) {

RowMapper<User> userRowMapper = (ResultSet rs, int i) ->

new User(

rs.getString("ACCOUNT_NAME"),

rs.getString("PASSWORD"),

rs.getBoolean("ENABLED"),

65




AuthorityUtils.createAuthorityList("ROLE_USER", "ROLE_ADMIN"));

return username ->

jdbcTemplate.queryForObject("SELECT * from ACCOUNT where

ACCOUNT_NAME = ?",

userRowMapper, username);

}

@Autowired

private UserDetailsService userDetailsService;

@Override

public void init(AuthenticationManagerBuilder auth) throws Exception {

auth.userDetailsService(this.userDetailsService);

}

}

Below shows shows the Jdbc SecurityConfiguration.java class . Let’s examine it:

• @Configuration . The JdbcSecurityConfiguration.java class is marked with the

@Configuration , which allows Spring Boot to recognize this class as another configuration

file where normally you declare your beans. It’s the same as using an XML file.

• @EnableGlobalAuthentication . This annotation marks the class and configures all the

necessary beans to activate the security on the application.

• GlobalAuthenticationConfigurerAdapter . The JdbcSecurityConfiguration.java class extends

from the GlobalAuthenticationConfigurerAdapter abstract class. This class also implements

the SecurityConfigurer interface and exposes an init method that will be overridden in the

JdbcSecurityConfiguration.java class.

• init(AuthenticationManagerBuilder) . Overrides the GlobalAuthenticationConfigurerAdapter

init method. In this method, the AuthenticationManagerBuilder instance is used to build in-

memory, LDAP, or JDBC-based authentication by setting up a UserDetailsService instance.

• @Bean/userDetailsService(JdbcTemplate) . This method will set up a JdbcTemplate instance

that will create a new org.springframework.security.core.userdetails.User instance after a

ResultSet is returned by using RowMapper that will match its constructor ( User ). This User

instance accepts the username , password , enabled , accountNonExpired ,

credentialsNonExpired , accountNonLocked , and authorities collections as the constructor’s

parameters. How the ResultSet will match the RowMapper ? Well, the Spring Security team

• provides a SQL schema that will work by adding the users. Don’t worry, as you are going to

see the SQL schema in just a moment. If you wonder where this is, you can go to

https://docs.spring.io/spring-security/site/docs/current/reference/html/appendix-

schema.html .

• @Autowired/userDetailsService . This instance is retrieved from the userDetailsService

method because it's declared as a bean.

Remember that you have the InMemorySecurityConfiguration class, so this means that only one can

be used, not both. So you can leave it and the JdbcSecurityConfiguration will take precedence and all

the users will be in the MySQL database. Another option is that you can comment out the main

annotation (@Configuration and @EnableGlobalAuthentication) and it will be the same. The best

solution is to use profiles, by using the @Profile annotation and activating the profiles at run time

with -Dspring.active.profiles=memory or whatever name you give to the profile.

Because this is a JDBC security, you need to add the table with its data to the src/main/resources/

schema.sql file. Here it will be for the table description and for the src/main/resources/data.sql .

src/main/resources/schema.sql

66

-- SECURITY: USER ACCOUNT

DROP TABLE IF EXISTS account;

CREATE TABLE account ( ACCOUNT_NAME VARCHAR(255) NOT NULL,

PASSWORD VARCHAR(255 ) NOT NULL,

ID SERIAL,

ENABLED BOOL DEFAULT true) ;

-- JOURNAL TABLE: ENTRY

DROP TABLE IF EXISTS entry;

CREATE TABLE entry (

ID BIGINT(20) NOT NULL AUTO_INCREMENT,

CREATED DATETIME DEFAULT NULL,

SUMMARY VARCHAR(255) DEFAULT NULL,

TITLE VARCHAR(255) DEFAULT NULL,

PRIMARY KEY (ID)

);

src/main/resources/data.sql

-- USERS IN JOURNAL

INSERT INTO ACCOUNT(account_name , password) VALUES('springboot', 'isawesome');

INSERT INTO ACCOUNT(account_name , password) VALUES('springsecurity',

'isawesometoo');

-- JOURNAL DATA

INSERT INTO ENTRY(title,summary,created) VALUES('Get to know Spring Boot','Today I

will learn Spring Boot','2016-01-02 00:00:00.00');

INSERT INTO ENTRY(title,summary,created) VALUES('Simple Spring Boot Project','I

will do my first Spring Boot project','2016-01-03 00:00:00.00');

INSERT INTO ENTRY(title,summary,created) VALUES('Spring Boot Reading','Read more

about Spring Boot','2016-02-02 00:00:00.00');

INSERT INTO ENTRY(title,summary,created) VALUES('Spring Boot in the Cloud','Learn

Spring Boot using Cloud Foundry','2016-02-05 00:00:00.00');


After executing the command, you can go to http://localhost:8080 and use the springsecurity

username and the isawesometoo password. That’s it; it’s very easy to implement JDBC security.

Some REST Security configurations and Spring Boot with OAuth2 documentation and examples are

left to complete Spring Security.

Spring Boot Starters

Spring Boot Starter dependencies greatly simplify the dependencies section of your project’s build

specification by aggregating commonly used dependencies under more coarse-grained (having a

large) dependencies. Your build will transitively resolve the dependencies that are declared in the

starter dependency. Your build will transitively resolve the dependencies that are declared in the

starter dependency.

Not only do starter dependencies keep the dependencies section of the build smaller, they are

typically organized by the type of functionality they bring to an application. For example rather than

68

specify libraries required for validation (such as Hibernate Validator and Tomcat embedded

expression language), you can simply add the spring-boot-starter-validator starter as a dependency.

Below table shows list of Spring Boot starter dependencies along with the dependencies that they

transitively declare.
