spring的事物控制

1.在service层进行声明式事物控制

<?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:tx="http://www.springframework.org/schema/tx"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">


    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>
    
  
  <!--支持以注解的形式的事物 -->
    <tx:annotation-driven/>

<tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="find*" propagation="NOT_SUPPORTED" rollback-for="Exception"/> <tx:method name="query*" propagation="NOT_SUPPORTED" rollback-for="Exception"/> <tx:method name="update*"
 propagation="REQUIRED" rollback-for="Exception"/> <tx:method name="modify*" propagation="REQUIRED" rollback-for="Exception"/> <tx:method name="delete*" propagation="REQUIRED" rollback-for="Exception"/> <tx:method name="remove*" propagation="REQUIRED" rollback-for="Exception"/>
 <tx:method name="add*" propagation="REQUIRED" rollback-for="Exception"/> <tx:method name="insert*" propagation="REQUIRED" rollback-for="Exception"/> </tx:attributes> </tx:advice> <aop:config> <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.kong.qingwei.service.*.*(..))"/>
 </aop:config></beans>




如上配置好后，如果在service层遇到异常就会回滚

2.如果想在controller层控制事物，则需要在上面配置文件中添加
  <!--支持以注解的形式的事物 -->
    <tx:annotation-driven/>

表示可以在Controller文件中添加

@Transactional注解进行事物控制
