Spring hibernate，如何在事务提交或事务回滚之后调用某种方法

问题描述

在事务成功或回滚之后，我需要调用一些方法。我正在使用

 < bean name =openSessionInViewInterceptorclass =org.springframework.orm.hibernate3.support.OpenSessionInViewInterceptor > 
< property name =sessionFactory> 
< ref local =mysessionFactory/> 
< / property> 
< / bean> 
 
< bean id =txManagerclass =org.springframework.orm.hibernate3.HibernateTransactionManager> 
< property name =sessionFactory> 
< ref local =mysessionFactory/> 
< / property> 
< / bean> 
 
< tx：注解驱动的事务管理器=txManagerproxy-target-class =true/> 
  

应用程序使用一些外部Web服务，当内部事务回滚时需要清除这些服务。
如何在不使用声明式事务管理的情况下完成此任务。

解决方案

• 从Hibernate开始，您可以扩展 code>并覆盖
afterTransactionCompletion（）方法并将其注册到
SessionFactoryBean 或 HibernateTransactionManager 。

从Spring可以扩展 TransactionSynchronizationAdapter 覆盖 afterCompletion（），并且在适当时用
进行注册TransactionSynchronizationManager＃registerSynchronization（）

$ p








$ b $

使用Spring Aop为所有使用 @Transactional

@Aspect $ b $ class TransactionAspect extends TransactionSynchronizationAdapter {

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

}

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





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.

解决方案

• From Hibernate, you could extends EmptyInterceptor and overrideafterTransactionCompletion() method and register it inSessionFactoryBean or HibernateTransactionManager.

• From Spring you could extends TransactionSynchronizationAdapter andoverride afterCompletion() and register when appropriate withTransactionSynchronizationManager#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
    }
}
