spring MVC使用aop无效的相关说明

下文笔者着重讲述AOP不起作用的相关说明,如下所示:

 

定义Aspect

 
package com.java265.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 FunctionMonitor {



    @Pointcut("execution(public * com.java265.controller.*.*(..))")
    private void pointCutMethod() {
    }

    //声明环绕通知
    @Around("pointCutMethod()")
    public Object doAround(ProceedingJoinPoint pt) throws Throwable {
        long begin = System.nanoTime();
        Object o = pt.proceed();
        long end = System.nanoTime();
        String s = pt.getTarget().getClass()+"."+pt.getSignature().getName()+"----"+(end-begin)/1000000;
        System.out.println(s);
        System.out.println("aop---end");

        return o;
    }

}

配置xml--springmvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context
       https://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/mvc
       https://www.springframework.org/schema/mvc/spring-mvc.xsd

       http://www.springframework.org/schema/aop
       http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
">

    <!--设置包扫描器-->
    <context:component-scan base-package="com.java265.controller">
    </context:component-scan>
    <!--设置注解驱动-->
    <mvc:annotation-driven />

    <aop:aspectj-autoproxy proxy-target-class="true" />
    <bean class="com.java265.aop.FunctionMonitor"/>
    <!--设置视图解析器-->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/admin/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>

    <!--设置文件上传核心组件-->
    <bean id="multipartResolver"
          class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

    </bean>


</beans>

当AOP不起作用时,请着重注意以下几个地方,如:

   <!--设置包扫描器-->
    <context:component-scan base-package="com.java265.controller">
    </context:component-scan>
    <!--设置注解驱动-->
    <mvc:annotation-driven />

    <aop:aspectj-autoproxy proxy-target-class="true" />
    <bean class="com.java265.aop.FunctionMonitor"/>
