这个案例和前一篇文章的案例是一样的，我们修改的其实只是ApplicationContext.xml文件，其他代码不会变所以这里就不多做解释了。

直接给出ApplicationContext.xml代码。里面的注释好好看一下。

<!-- 第一步:配置事务管理器 -->
<!-- 事务管理器
之前提过的。事务管理器针对不同的持久层有不同的类，比如Spring自带的SpringJdbc,Hibernata等等。这里用的
就是Sping自带的Jdbc，所以这里用的类是DataSourceTransactionManager
-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!--
为什么要把dataSource交给transactionManager(事务管理器),
因为事务管理器，需要从数据源获取连接，才能开启事务，提交事务，回滚事务 -->

</bean>
<!--第二步： 配置通知， -->
<!-- 需要通知(Advice)，用来对事务增强 。其实advice代表的是环绕前，环绕后要干的事情，
环绕前，环绕后用来干嘛，不就是开启事务，提交事务吗?但是开启事务，提交事务由什么来完成呢？不就是
transactionManager来做。

-->
<tx:advice id="transactionAdvice"  transaction-manager="transactionManager">

<!-- 接下来配事务的配置属性，为什么要配？这样的话，对什么方法，应用怎样的事务配置就知道了。这些配置信息就会成为TransactionDefinition对象
TransactionDefinition里面有什么还记得吗?
之前的论文提过的有四类：1.以ISOLATION开头的 ISOLATION_* ：事务隔离级别
                  2.PROPAGATION_* 事务的传播行为等四个。

-->
<tx:attributes>
<!--
name 方法名
isolation 隔离级别
propagation 传播行为
 timeout 超时时间
 read-only 是否只读 （false代表可以更改，true的话代表不能更改）

 rollback-for 配置一些异常类型，发生这些异常 回滚事务。
no-rollback-for 配置一些异常类型，发生这些异常不 回滚事务。
如果没有配置上面两个，默认发生什么异常都要回滚，
-->
  <tx:method name="transfer" isolation="DEFAULT" propagation="REQUIRED"  timeout="-1" read-only="false"/>

<aop:config>
    <aop:advisor advice-ref="transactionAdvice" pointcut="execution(* cn.itcast.service.AccountServiceimpl.*(..) )"/>

</aop:config>

</beans>

执行结果：已经有事务的控制了。要不一起成功要不都不成功。

注意！注意！
