spring 写junit测试时使用aop报错

当我在我的配置文件中加上如下配置会包下面的错误，我不加时就不会出错这是为什么

 <aop:config>
        <aop:pointcut id="interceptorPointCuts" expression="execution(* cn.qtt.service.*.*(..)) " />

        <aop:pointcut id="interceptorPointCutsNew" expression="execution(* cn.qtt.advert.service.*.*(..)) " />

        <aop:advisor advice-ref="txAdvice" pointcut-ref="interceptorPointCuts" />

        <aop:advisor advice-ref="txAdvice" pointcut-ref="interceptorPointCutsNew" />
    </aop:config>

    spring的AOP实现可以使用JDK的动态代理目标对象实现是接口，而你的Can not set cn.qtt.service.impl.UserServiceImpl field AdvertServiceTest.userService to com.sun.proxy.$Proxy17这里说的数实现类，改成接口应该就可以了，或者改成CGLIB实现AOP使用不实用接口， 添加CGLIB库，SPRING_HOME/cglib/*.jar * 在spring配置文件中加入
