本文介绍了如何在Spring中实现声明式事务管理，通过XML配置和AOP方式来确保多个操作要么全部成功，要么全部失败。文章详细展示了配置过程及关键代码。

当要求多个事务要么同时完成，要么同时无法完成时，就涉及到了事务的处理.

Spring提供了声明式事务管理，其原理是通过AOP来完成的。

<bean id="txManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

<tx:annotation-driven transaction-manager="txManager"/>

tx就是事务管理

并引入相应的命名空间。

xml配置：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	<!-- <aop:aspectj-autoproxy/> -->
	
	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">

    </bean>

	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<property name="mappingResources">

            </props>

	</bean>
	
	<bean id = "userDaoImpl" class="com.dw.impl.UserDaoImpl">

	</bean>
	<bean id = "logDaoImpl" class = "com.dw.impl.LogDaoImpl">
	  <property name="sessionFactory" ref="sessionFactory"/>
	</bean>
	<bean id ="service" class = "com.dw.service.ServiceUser">
	  <property name="userDao" ref="userDaoImpl"/>
	  <property name="logDao" ref="logDaoImpl"/>
	</bean>
	
	<bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
      <property name="sessionFactory" ref="sessionFactory"/>
    </bean>
    
	<tx:annotation-driven transaction-manager="txManager"/>
	
	
	
	
	
	<!-- 
	<bean id = "iterception" class="com.dw.model.Iterception"/>
	<aop:config>
	  <aop:pointcut expression="execution(* com.dw.car.*.*(..))" id="point"/>
	  <aop:aspect id="aspect" ref="iterception">
	    <aop:before method="before1" pointcut-ref="point"/>
	    <aop:after-returning method="after1" pointcut-ref="point"/>
	    <aop:around method="around1" pointcut="execution(* com.dw.car.*.*(..))"/>
	  </aop:aspect>
	</aop:config> -->
</beans>

在相应的处理方法上使用注解@transactional

	@Transactional
	public void add(User user) {
		userDao.save(user);
		Log log = new Log();
		log.setName("您插入了一条数据！");
		logDao.save(log);
	}

然后通过getCurrentSession()获取Session对象。
