Spring--hibernate整合_事务管理

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。

<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" 
    	xmlns:p="http://www.springframework.org/schema/p"
    	xmlns:aop="http://www.springframework.org/schema/aop"
    	xmlns:tx="http://www.springframework.org/schema/tx"
    	xsi:schemaLocation="http://www.springframework.org/schema/beans

             http://www.springframework.org/schema/context/spring-context-2.5.xsd

    	xmlns:context="http://www.springframework.org/schema/context">
    	
    	<context:component-scan base-package="com.dw"/>
    	
    	
    	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3306/user"/>
        <property name="username" value="root"/>
        <property name="password" value="root"/>
        </bean>
    
    	<bean id="sessionFactory"
    		class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    		<property name="dataSource" ref="dataSource" />
    		<property name="mappingResources">
    			<list>
    				<value>com/dw/config/User.hbm.xml</value>
    				<value>com/dw/config/Log.hbm.xml</value>
    			</list>
    		</property>
    		<property name="hibernateProperties">
    			<props>
    				<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
    				<prop key="hibernate.hbm2ddl.auto">update</prop>
    				<prop key="hibernate.show_sql">true</prop>
                </props>
    		</property>
    	</bean>
    	
    	<bean id = "userDaoImpl" class="com.dw.impl.UserDaoImpl">
    	  <property name="sessionFactory" ref="sessionFactory"/>
    	</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"/>
    	
    	
    	
    	
    	
    	
    </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。
