一、applicationContext.xml配置:定义事务和aop
?
<!-- 定义事务传播属性 --> <tx:advice id="txAdvice" transaction-manager="txManager"> <tx:attributes> <tx:method name="get*" propagation="NOT_SUPPORTED" read-only="true"/> <tx:method name="*" /> </tx:attributes> </tx:advice> <tx:annotation-driven transaction-manager="txManager"/> <!--aop错误引入spring.jar--> <aop:config> <!-- 描述切入点 --> <!-- 1)execution(* *(..)) 表示匹配所有方法 2)execution(public * com. savage.service.UserService.*(..)) 表示匹配com.savage.server.UserService中所有的公有方法 3)execution(* com.savage.server..*.*(..)) 表示匹配com.savage.server包及其子包下的所有方法 --> <aop:pointcut id="transactionPointCut" expression="execution(* com.cn.ssm.dao2..*.*(..))"/> <aop:advisor pointcut-ref="transactionPointCut" advice-ref="txAdvice"/> </aop:config>
?
二、实现类UserDaoImpl.java
@Transactional
public class UserDaoImpl implements UserDao { @Transactional(rollbackFor = Exception.class) public void insertUser() throws Exception { jdbcTemplate.update("insert into user (name) values ('01');"); jdbcTemplate.update("update user set name=a where id=0;"); } }
?
三、Test.java 测试
?
?
public static void main(String[] args) throws Exception { ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext_1.xml"); UserDao userDaoImpl = (UserDao) context.getBean("userDaoImpl"); userDaoImpl.insertUser(); }
?
