Spring 事务之Annotation实现方式

 在SPRING中配置支持Annotation方式实现事务。也就是。tx:annotation-drive

<?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: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/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"><!-- hibernate start --><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/hbtest" /><property name="username" value="root" /><property name="password" value="sa" /><property name="maxActive" value="100" /><property name="minIdle" value="30" /><property name="maxWait" value="500" /></bean><bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><property name="dataSource" ref="dataSource" /><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop><prop key="hibernate.show_sql">true</prop></props></property><property name="mappingResources"><list><value>com/test/entity/User.hbm.xml</value><value>com/test/entity/Log.hbm.xml</value></list></property></bean> <!-- 配置事务管理器 --><bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory"> <ref bean="sessionFactory"/> </property></bean><tx:annotation-driven transaction-manager="transactionManager"/> </beans>

 

然后就在要注入的service层的类和方法上申明@Transactional注解就表明该方法要进行事务。当然确保你的数据库支持事务才行哈。
