spring aop 如何切面到mvc 的controller--转载

原文：http://yjian84.iteye.com/blog/1920787

网上搜罗半天，不知道什么原因，看了源码，好像他们说的controller 是不受代理的，也对哈，不知道怎么办，于是在http://stackoverflow.com/questions/17834958/spring-aop-is-not-working-in-with-mvc-structure?rq=1 这个地方有个人说了： 

<context:component-scan base-package="com.dao" /> 
<mvc:annotation-driven/> 

<aop:aspectj-autoproxy />   
from application-context.xml to controller-servlet.xml? 

The aspects and the beans to be applied needs to be in the same ApplicationContext but ApplicationContext is not aware of WebApplicationContext . 


Indeed your controller (annotated by @Controller) and your aspects (annotated by @Aspect) should be in the same Spring context. 

Usually people define their controllers in the dispatch-servlet.xml or xxx-servlet.xml and their service beans (including the aspects) in the main applicationContext.xml. It will not work. 

When Spring initializes the MVC context, it will create a proxy for your controller but if your aspects are not in the same context, Spring will not create interceptors for them. 


这个人说的好像很对啊。我把aspectj 和springmvc的配置文件放到一起就可以用到controller上了。 

spring-mvc.xml 

<context:component-scan base-package="com.cms.controller" /><context:component-scan base-package="com.cms.aspectj" /><!-- <bean id="sysLogAspectJ" class="com.cms.aspectj.SysLogAspectJ" /> --><aop:aspectj-autoproxy proxy-target-class="true"><!-- <aop:include name="sysLogAspectJ" /> --></aop:aspectj-autoproxy><!-- <mvc:annotation-driven /> --><beanclass="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping" /><beanclass="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter" /> package com.cms.aspectj;import org.aspectj.lang.ProceedingJoinPoint; import org.aspectj.lang.annotation.Around; import org.aspectj.lang.annotation.Aspect; import org.aspectj.lang.annotation.Pointcut; import org.springframework.stereotype.Component;@Component @Aspect public class SysLogAspectJ {@Pointcut("within(@org.springframework.stereotype.Controller *)")public void cutController(){}@Around("cutController()")public Object recordSysLog(ProceedingJoinPoint point) throws Throwable{System.out.println("lfkdjj================================================================");return point.proceed();}}
