springMVC + mybatis 事务配置

springApplication.xml  配置  

 <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">  
        <property name="dataSource" ref="dataSource" />  
</bean>

 

<!-- 使用annotation注解方式配置事务 -->

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

 

 

 

事务需在bean 只才能实现

@Transactional(propagation=Propagation.REQUIRED, isolation=Isolation.READ_COMMITTED)
 public void topAdNetBarById(Long adId) throws Exception{
  AdNetbar netbar =  generalizeBusinessDao.getAdNetbarById(adId);
  generalizeBusinessDao.updTopByNetbarId(netbar.getNetbar_id());
  generalizeBusinessDao.topAdNetBarById(adId);
 }

 

 

还需要抛出异常事务才会回滚
