spring-data-jpa事务不起作用

天雨之梦 2015-12-23 11:44:30

spring-data-jpa中的repository事务没有问题，但是在Service中添加Transactional注解事务就不起作用，
中间有异常不能回滚，spring的配置如下

    <!-- 开启注解事务 -->

    <!--

        使用 JDK 动态代理： proxy-target-class="false" @Transactional可以标注在接口或者父类上

        使用CGLIB动态代理： proxy-target-class="true"  @Transactional不能标注在接口或者父类上，需要标注在业务实现类或是其方法上，否则事务不生效

    -->

    <tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true" />

请大神们给解答一些为什么在Service中配置事务不起作用？
