Question

您好我在我的问题上阅读了所有以前的主题并且我应用了所有建议，但我还没有找到解决方案。
在我的springMVC + AspectJ配置中，控制器工作正常，但不执行切入点。在这里我的配置和代码：

-- /WEB-INF/web.xml ---
        <web-app>
          <display-name>MODULE-WEB</display-name>

          <context-param>
                <param-name>contextConfigLocation</param-name>
                <param-value>WEB-INF/applicationContext.xml</param-value>
            </context-param>

           <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
           </listener> 
        ...

            <property name="businessInterface" value="it.max.test.services.ITestService"/>
            </bean> 

            </beans>

-- Monitor.java ---
package it.max.test.security;

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
import org.springframework.stereotype.Component;

@Component
@Target(value={ElementType.METHOD, ElementType.TYPE})
@Retention(value=RetentionPolicy.RUNTIME)
public @interface Monitor {
            }

   -- AuthorizationInterceptor.java --
    package it.max.test.security;

    import org.aspectj.lang.annotation.Aspect;
    import org.aspectj.lang.annotation.Before;

    @Aspect
    @Component
    public class AuthorizationInterceptor {

       @Before(value="@within(it.max.test.security.Monitor) || @annotation(it.max.test.security.Monitor)")
        public void before(JoinPoint jp){
            Object[] paramValues=jp.getArgs();
            String[] paramNames=((CodeSignature)jp.getStaticPart().getSignature()).getParameterNames();
            for(int i=0;i<paramValues.length;i++){
                System.out.println("["+paramNames[i]+"]:["+paramValues[i]+"]"); 
            }
        }
    }

--TestController.java---
package it.max.test.controllers;

import it.max.test.security.Monitor;
import it.max.test.services.ITestService;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;

import org.springframework.web.servlet.ModelAndView;

@Controller
public class TestController {

    @Autowired
    private ITestService testService;

    @Monitor
    @RequestMapping("/test.view")
    protected ModelAndView test(HttpServletRequest arg0,HttpServletResponse arg1) throws Exception {
        ModelAndView mv=new ModelAndView();
        testService.test("AAA");
        mv.setViewName("test");
        return mv;
    }
}

您的带注释的方法为protected，但应为public。

Spring manual, chapter 9.2.3说：

由于Spring的AOP框架基于代理的特性，根据定义，受保护的方法既不是针对JDK代理（这不适用），也不针对CGLIB代理（这在技术上可行，但不建议用于AOP）目的）。因此，任何给定的切入点都只能与公共方法匹配！

如果您想匹配protected或private方法，请通过LTW使用AspectJ。

没有调用SpringMVC + AspectJ
