java - Spring hibernate , how to call some method after transaction commit or transaction rollback

Question

I need to call some method after transaction succes or rollback. I am using as

    <bean name="openSessionInViewInterceptor" class="org.springframework.orm.hibernate3.support.OpenSessionInViewInterceptor">
                <property name="sessionFactory">
                    <ref local="mysessionFactory"/>
                </property>
    </bean>

    <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory">
            <ref local="mysessionFactory"/>
        </property>
    </bean>

<tx:annotation-driven transaction-manager="txManager" proxy-target-class="true"/>

The application use some external web services which needs to be "cleaned" when the internal transaction gets rollbacked. Is there way how to accomplish this without using declarative transaction management.

Answer 1

• From Hibernate, you could extends EmptyInterceptor and override afterTransactionCompletion() method and register it in SessionFactoryBean or HibernateTransactionManager.

• From Spring you could extends TransactionSynchronizationAdapter and override afterCompletion() and register when appropriate with TransactionSynchronizationManager#registerSynchronization().

Edit

An Example of using Spring Aop to add a synchronization to all methods annotated with @Transactional

@Aspect
class TransactionAspect extends TransactionSynchronizationAdapter {

    @Before("@annotation(org.springframework.transaction.annotation.Transactional)")
    public void registerTransactionSyncrhonization() {
        TransactionSynchronizationManager.registerSynchronization(this);

    }

    @Override
    public void afterCompletion(int status) {
        // code 
    }
}
