• Spring Aspect实现AOP切面


    百度搜索的大部分的文章(demo)都只是对简单的方法进行切面(例如:public String say(String name)),却未介绍在入参是不固定的时候改怎么处理,后来查到可以使用org.aspectj.lang.JoinPoint类获取到被代理类的信息和方法的入参信息。

    参考BLOG: http://blog.csdn.net/wangyang1354/article/details/50896349

    但是在对dubbo的类进行Aspect代理时会出现如下错误:(因为dubbo已经对此类代理过一次了,Aspect好像只能对纯类进行切面)
