  <!--事务管理器-->
  <bean id="manager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource"/>

  <!--配置事务-->
  <aop:config>
    <!--配置切入点，这里写自己想要使用Spring事务管理的类或接口，在上篇博客中有切入点配置方法-->
    <aop:pointcut id="pointcut" expression="execution( * com.test.tx.service.IAccountService.*(..))"/>
    <!--配置切面-->
    <aop:advisor advice-ref="advice" pointcut-ref="pointcut"/>
  </aop:config>
  <!--事务增强器-->
  <tx:advice id="advice" transaction-manager="manager">
    <tx:attributes>
      <!--read-only可以将查询的方法设为只读事务-->
      <tx:method name="*" read-only="false"/>
    </tx:attributes>
  </tx:advice>
</beans>

<!--事务的注解驱动,注解解析器需要关联事务管理器-->
  <tx:annotation-driven transaction-manager="manager"/>
