This controller is use to redirect the page in the Spring 2.5 Web MVC applications. This controller doesn't This controller is use to redirect the page in the Spring 2.5 Web MVC applications. This controller doesn't require controller class. This controller provides an alternative to sending a request straight to a view such require controller class. This controller provides an alternative to sending a request straight to a view such as a JSP. we will configure just declared the as a JSP. we will configure just declared the ParameterizableViewControllerParameterizableViewController bean and set the view name bean and set the view name through the "through the "viewNameviewName" property." property.

Now we will used ParameterizedViewController for control the behavior of the application.Now we will used ParameterizedViewController for control the behavior of the application.

AbstractWizardFormControllerAbstractWizardFormController Spring Web MVC provides Spring Web MVC provides AbstractWizardFormController AbstractWizardFormController class that handle wizard form. In this tutorial, we will used class that handle wizard form. In this tutorial, we will used

AbstractWizardFormController AbstractWizardFormController class. The AbstractWizardFormController class provide us to store and show the forms class. The AbstractWizardFormController class provide us to store and show the forms data with multiple pages. It manage the navigation between pages and validate the user input data form a single page of the data with multiple pages. It manage the navigation between pages and validate the user input data form a single page of the whole model object at once. In this tutorial we will discuss about this controller.whole model object at once. In this tutorial we will discuss about this controller.

Spring Transaction ManagementSpring Transaction ManagementThe key to the Spring transaction abstraction is the notion of a transaction

strategy. A transaction strategy is defined by the org.springframework.transaction.PlatformTransactionManager interface:public interface PlatformTransactionManager { TransactionStatus getTransaction(TransactionDefinition definition) throws TransactionException; void commit(TransactionStatus status) throws TransactionException; void rollback(TransactionStatus status) throws TransactionException;}

This is primarily a service provider interface (SPI), although it can be used programmatically from your application code. Because PlatformTransactionManager is an interface, it can be easily mocked or stubbed as necessary. It is not tied to a lookup strategy such as JNDI. PlatformTransactionManager implementations are defined like any other object (or bean) in the Spring Framework IoC container. This benefit alone makes Spring Framework transactions a worthwhile abstraction even when you work with JTA. Transactional code can be tested much more easily than if it used JTA directly.

Again in keeping with Spring's philosophy, the TransactionException that can be thrown by any of the PlatformTransactionManager interface's methods is unchecked (that is, it extends thejava.lang.RuntimeException class). Transaction infrastructure failures are almost invariably fatal. In rare cases where application code can actually recover from a transaction failure, the application developer can still choose to catch and handle TransactionException. The salient point is that developers are not forced to do so.

The getTransaction(..) method returns a TransactionStatus object, depending on a TransactionDefinition parameter. The returned TransactionStatus might represent a new transaction, or can represent an existing transaction if a matching transaction exists in the current call stack. The implication in this latter case is that, as with Java EE transaction contexts, a TransactionStatus is associated with a thread of execution.

Transaction DenifitionTransaction DenifitionThe TransactionDefinition interface specifies:• Isolation: The degree to which this transaction is isolated from the work of other transactions. Forexample, can this transaction see uncommitted writes from other transactions?• Propagation: Typically, all code executed within a transaction scope will run in that transaction.However, you have the option of specifying the behavior in the event that a transactional method isexecuted when a transaction context already exists. For example, code can continue running in theexisting transaction (the common case); or the existing transaction can be suspended and a newtransaction created. Spring offers all of the transaction propagation options familiar from EJB CMT.To read about the semantics of transaction propagation in Spring, see the section called “Transactionpropagation”.• Timeout: How long this transaction runs before timing out and being rolled back automatically by theunderlying transaction infrastructure.• Read-only status: A read-only transaction can be used when your code reads but does not modify data.Read-only transactions can be a useful optimization in some cases, such as when you are usingHibernate.

These settings reflect standard transactional concepts. If necessary, refer to resources that discusstransaction isolation levels and other core transaction concepts. Understanding these concepts is essentialto using the Spring Framework or any transaction management solution.

Transaction StatusThe TransactionStatus interface provides a simple way for transactional code

to control transaction execution and query transaction status. The concepts should be familiar, as they are common to all transaction APIs:public interface TransactionStatus extends SavepointManager {

boolean isNewTransaction();boolean hasSavepoint();void setRollbackOnly();boolean isRollbackOnly();void flush();boolean isCompleted();

}Regardless of whether you opt for declarative or programmatic transaction

management in Spring, defining the correct PlatformTransactionManager implementation is absolutely essential. You typically define this implementation through dependency injection.

PlatformTransactionManager implementations normally require knowledge of the environmentin which they work: JDBC, JTA, Hibernate, and so on. The following examples show how you

can define a local PlatformTransactionManager implementation. (This example works with plain JDBC.)

You define a JDBC DataSource<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-

method="close"><property name="driverClassName" value="${jdbc.driverClassName}" /><property name="url" value="${jdbc.url}" /><property name="username" value="${jdbc.username}" /><property name="password" value="${jdbc.password}" /></bean>The related The PlatformTransactionManager bean definition will then have a reference to theDataSource definition. It will look like this:<bean id="txManager"

class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource"/></bean>

Hibernate TMHibernate TMYou can also use Hibernate local transactions easily, as shown in the following examples. In this case, you need

to define a Hibernate LocalSessionFactoryBean, which your application code will use to obtain Hibernate Session instances.

The DataSource bean definition will be similar to the local JDBC example shown previously and thus is not shown in the following example.

NoteIf the DataSource, used by any non-JTA transaction manager, is looked up via JNDI and managed by a Java EE

container, then it should be non-transactional because the Spring Framework, rather than the Java EE container, will manage the transactions. The txManager bean in this case is of the HibernateTransactionManager type. In the same way as the DataSourceTransactionManager needs a reference to the DataSource, the HibernateTransactionManager needs a reference to the SessionFactory.

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><property name="dataSource" ref="dataSource" /><property name="mappingResources"><list><value>org/springframework/samples/petclinic/hibernate/petclinic.hbm.xml</value></list></property><property name="hibernateProperties"><value>hibernate.dialect=${hibernate.dialect}</value></property></bean><bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory" /></bean>
