spring aop 如何切面到mvc 的controller

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 

Java代码  

1. <context:component-scan base-package="com.cms.controller" />  
2. <context:component-scan base-package="com.cms.aspectj" />  
3. <!-- <bean id="sysLogAspectJ" class="com.cms.aspectj.SysLogAspectJ" /> -->  
4. <aop:aspectj-autoproxy proxy-target-class="true">  
5. <!--     <aop:include name="sysLogAspectJ" /> -->  
6. </aop:aspectj-autoproxy>  
7. <!-- <mvc:annotation-driven /> -->  
8. <bean  
9.     class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping" />  
10. <bean  
11.     class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter" />  

sysLogAspectJ 

Java代码  

1. package com.cms.aspectj;  
2.   
3. import org.aspectj.lang.ProceedingJoinPoint;  
4. import org.aspectj.lang.annotation.Around;  
5. import org.aspectj.lang.annotation.Aspect;  
6. import org.aspectj.lang.annotation.Pointcut;  
7. import org.springframework.stereotype.Component;  
8.   
9. @Component  
10. @Aspect   
11. public class SysLogAspectJ {  
12.   
13.     @Pointcut("within(@org.springframework.stereotype.Controller *)")  
14.     public void cutController(){  
15.           
16.     }  
17.       
18.     @Around("cutController()")  
19.     public Object recordSysLog(ProceedingJoinPoint point) throws Throwable{  
20.         System.out.println("lfkdjj================================================================");  
21.         return point.proceed();  
22.     }  
23.       
24.       
25.       
26. }
