Class OpenSessionInterceptor

java.lang.Object

org.springframework.orm.hibernate4.support.OpenSessionInterceptor

All Implemented Interfaces:

Advice, Interceptor, MethodInterceptor, InitializingBean

public class OpenSessionInterceptor
extends java.lang.Object
implements MethodInterceptor, InitializingBean

Simple AOP Alliance MethodInterceptor implementation that binds a new Hibernate Session for each method invocation, if none bound before.

This is a simple Hibernate Session scoping interceptor along the lines of OpenSessionInViewInterceptor, just for use with AOP setup instead of MVC setup. It opens a new Session with flush mode "MANUAL" since the Session is only meant for reading, except when participating in a transaction.

Since:

4.0.2

Method Detail

setSessionFactory

public void setSessionFactory(SessionFactory sessionFactory)

Set the Hibernate SessionFactory that should be used to create Hibernate Sessions.

getSessionFactory

public SessionFactory getSessionFactory()

Return the Hibernate SessionFactory that should be used to create Hibernate Sessions.

afterPropertiesSet

public void afterPropertiesSet()

Description copied from interface: InitializingBean

Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.

This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.

Specified by:

afterPropertiesSet in interface InitializingBean

invoke

public java.lang.Object invoke(MethodInvocation invocation)
                        throws java.lang.Throwable

Description copied from interface: MethodInterceptor

Implement this method to perform extra treatments before and after the invocation. Polite implementations would certainly like to invoke Joinpoint.proceed().

Specified by:

invoke in interface MethodInterceptor

Parameters:

invocation - the method invocation joinpoint

Returns:

the result of the call to Joinpoint.proceed(); might be intercepted by the interceptor

Throws:

java.lang.Throwable - if the interceptors or the target object throws an exception

openSession

protected Session openSession()
                       throws DataAccessResourceFailureException

Open a Session for the SessionFactory that this interceptor uses.

The default implementation delegates to the SessionFactory.openSession() method and sets the Session's flush mode to "MANUAL".

Returns:

the Session to use

Throws:

DataAccessResourceFailureException - if the Session could not be created
