spring aop 如何切面到mvc 的controller, service

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。[color=red]我把aspectj 和springmvc的配置文件放到一起就可以用到controller上了[/color]。

在servlet.xml加入

<aop:aspectj-autoproxy proxy-target-class="true"></aop:aspectj-autoproxy>

sysLogAspectJ

package com.pandy.core.aop;

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;

 */
@Aspect
@Component
public class ControllerLogAspect {

    @Pointcut("within(@org.springframework.stereotype.Controller *)")
    public void cutController(){
    }

    @Around("cutController()")
    public Object recordSysLog(ProceedingJoinPoint point) throws Throwable{
        System.out.println("=================================ControllerLogAspect执行方法2");
        return point.proceed();
    }
}

拦截Service等

在applicationContext.xml(扫描service的类的配置文件)加入

<aop:aspectj-autoproxy proxy-target-class="true"></aop:aspectj-autoproxy>

package com.pandy.core.aop;

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;

@Aspect
@Component
public class ServiceLogAspect {

    @Pointcut("within(@org.springframework.stereotype.Service *)")
    public void cutService(){
    }

    @Around("cutService()")
    public Object recordSysLog(ProceedingJoinPoint point) throws Throwable{
        System.out.println("=================================ServiceLogAspect执行方法2");
        return point.proceed();
    }
}
