这事原来的啊！代码！我想加入aop切面作为才做日志！不知道怎么下手！请高手讲解一下。springjpaaop

Answer 1

<aop:config>
    <!-- 配置aspect切面类 -->
<aop:aspect ref="userAspect">
    <!-- 配置pointcut,即切入点，对哪些类的哪些方法起到AOP的作用 -->
<aop:pointcut id="userServiceMethods"
expression="execution(* org.wiki.spring.service.UserServiceImpl.*(..))" />
<!-- 配置advice,即Aspect类中的logging()方法，这里采用在业务方法执行前进行拦截 -->
<aop:before method="logging" pointcut-ref="userServiceMethods" />
</aop:aspect>

</aop:config>
这么加上可以吗？

Answer 2

但是我这么加上报错的啊！org/aspectj/weaver/reflect/ReflectionWorld$ReflectionWorldException

Answer 3

首先写个切面(Aspect),然后配置一个切入点和通知类型就可以了，当初我才写的时候也是折腾了一部分时间，后面自己看来一下文档，很快就会了。

我这么配置后！原来的login都登陆不进去了！为什么啊？
