Spring MVC 注解下Controller 的AOP

在使用spring框架时,通常用它的aop来记录日志,但在spring mvc采用@Controller注解时,对Controller进行Aop拦截不起作用,原因是该注解的Controller已被spring容器内部代理了.

需要对org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter进行Aop才能起作用.经过多次测试可行.

package com.autoabacus.dal.controller;import org.aspectj.lang.ProceedingJoinPoint;import org.aspectj.lang.annotation.Around;import org.aspectj.lang.annotation.Aspect;import org.springframework.stereotype.Component;@Component@Aspectpublic class Aop {public Aop() {System.out.println("Aop");}// @Around("within(org.springframework.web.bind.annotation.support.HandlerMethodInvoker..*)")@Around("execution(* org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter.handle(..))")public Object aa(ProceedingJoinPoint pjp) throws Throwable {try {Object retVal = pjp.proceed();System.out.println(retVal);return retVal;} catch (Exception e) {System.out.println("异常");return null;}}}

Controller代码

package com.autoabacus.dal.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controller public class WelcomeController {@RequestMapping public void welcome() {if (true)throw new RuntimeException("fdsafds"); } }
