Spring 中自带的事务管理

Spring 集成 hibernate 的事务管理，不用我们手动开启和提交事务了：

需要在xml文件头部的 xsi:schemaLocation 添加：

http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd

hibernate 配置文件中可设的配置：

hibernate.current_session_context_class=org.springframework.orm.hibernate3.SpringSessionContext

此为默认值，可不设

aop 的设置：

<bean id="transaction_manager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
	<property name="sessionFactory" ref="sessionFactory">	</property>
</bean>
	
<tx:advice id="muser_txAdvice" transaction-manager="transaction_manager">
	<tx:attributes>
		<tx:method name="*" propagation="REQUIRED"/>
	</tx:attributes>
</tx:advice>
	
<bean id="muser_inter" class="org.aops.MuserAdvice">
	<property name="sessionFactory" ref="sessionFactory"></property>
</bean>

<aop:config>
	<aop:pointcut expression="execution(* org.services.impl.MuserServiceImpl.login(String, String))" id="login_pointCut" />
	<aop:advisor advice-ref="muser_inter" pointcut-ref="login_pointCut" />
	<aop:advisor advice-ref="muser_txAdvice" pointcut-ref="login_pointCut" />
</aop:config>

java 中的代码：

package org.aops;

import org.aopalliance.intercept.MethodInterceptor;
import org.aopalliance.intercept.MethodInvocation;
import org.hibernate.SessionFactory;

public class MuserAdvice implements MethodInterceptor {

	private SessionFactory sessionFactory;

	@Override
	public Object invoke(MethodInvocation arg0) throws Throwable {
		System.out.println("in");
		Object obj = arg0.proceed();
		System.out.println("out");
		return obj;
	}

	public SessionFactory getSessionFactory() {
		return sessionFactory;
	}

	public void setSessionFactory(SessionFactory sessionFactory) {
		this.sessionFactory = sessionFactory;
	}

}

控制台的输出：

in

Hibernate: 

    select

        muser0_.MUID as MUID1_,

        muser0_.MUNAME as MUNAME1_,

        muser0_.MUPWD as MUPWD1_ 

    from

        TEST.MUSER muser0_ 

    where

        muser0_.MUNAME=? 

        and muser0_.MUPWD=?
