spring_mvc_之AOP

Spring MVC 的AOP配置：

第一，WEB.XML,这里跟正常的Spring MVC一样，

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 

http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

<param-value>

第二、

Spring MVC 中web.xml红色部分的配置文件，文件名是gjkonline-servlet.xml，跟web.xml放在同一个目录下，具体内容是：

<?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:p="http://www.springframework.org/schema/p"

xmlns:context="http://www.springframework.org/schema/context"

xmlns:aop="http://www.springframework.org/schema/aop"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-3.0.xsd

        http://www.springframework.org/schema/aop  

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

<aop:aspectj-autoproxy/> 

<context:annotation-config />

<!-- Auto scan, declare the location path -->  

<context:component-scan base-package="com.gjkonline.springmvc.rest" />  

<!-- Using annontation -->  

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" /> 

<!-- Resolve the view, declare the prefix and suffix -->  

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"  

p:prefix="/view/" p:suffix=".jsp" p:viewClass="org.springframework.web.servlet.view.JstlView" />  

 

<bean id="multipartResolver"  

class="org.springframework.web.multipart.commons.CommonsMultipartResolver"  

p:defaultEncoding="utf-8" /> 

</beans>

此文件中红色标注的一定要加，要不然AOP切点，切不进去，这跟其它的框架下的AOP配置最大的区别；

第三，

applicationContext.xml这个配置文件没什么特别之处，我把关于AOP的配置，都放在了applicationContext-aop.xml文件中，具体引入部分是，

<import resource="applicationContext-aop.xml"/>

第四、

applicationContext-aop.xml配置文件的具体内容（我主要用的是注解方式来生成切片的）：

<?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:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="http://www.springframework.org/schema/beans 

            http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

            http://www.springframework.org/schema/context

            http://www.springframework.org/schema/context/spring-context-3.0.xsd

            http://www.springframework.org/schema/aop  

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

          

<context:annotation-config />

<context:component-scan base-package="com.gjkonline.aop" /> 

</beans>

第五：拦截器的JAVA类：

package com.gjkonline.aop;

import javax.servlet.http.HttpServletRequest;

import org.aspectj.lang.JoinPoint;

import org.aspectj.lang.ProceedingJoinPoint;

import org.aspectj.lang.annotation.After;

import org.aspectj.lang.annotation.Around;

import org.aspectj.lang.annotation.Aspect;

import org.aspectj.lang.annotation.Before;

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

import org.springframework.stereotype.Component;

import com.gjkonline.springmvc.rest.base.HomeBaseController;

import com.ibatis.dao.impl.CommonDAO;

@Component  

@Aspect 

public class LogServiceXMLAop {

private CommonDAO commonDAO;

@Autowired

public void setCommonDAO(CommonDAO commonDAO) {

this.commonDAO = commonDAO;

}

    @Before("execution(* com.gjkonline.springmvc.rest.DataHomeController.*Fws(..))")  

public void beforeMethod(JoinPoint jp) {

     try{

Object[] args = jp.getArgs();

String user="";

String url="";

for (int i = 0; i < args.length; i++){

if(args[i] instanceof HttpServletRequest)

{

HttpServletRequest request= (HttpServletRequest)args[i];

user = new HomeBaseController().getRestUserId(request);

url=request.getRequestURI();

}

}

this.commonDAO.insertLog(user, "宏观接口调用", url, "", "class com.gjkonline.springmvc.rest.macro.DataHomeController");

     }

     catch(Exception e){

     e.printStackTrace();

     }

}

}

这样全部配置完成了！
