1. 新建web project

2. 添加jar

3. 改写web.xml, 注意spring-servlet.xml的名字 

     
       
      	  
          
       
        index.jsp
         
          
        	
       
        springMVC
         	
       
        org.springframework.web.servlet.DispatcherServlet
         	
         		
        
         contextConfigLocation
          		
        
         classpath*:config/springAnnotation-servlet.xml
          	
         	
       
        1
         
        
        	
       
        springMVC
         	
       
        /
         
        
     

　4. 写　springAnnotation-servlet.xml , 第一处优化  <mvc:annotation-driven/> 代替引入2个bean

　　

5. 新建包 com.tgb.web.controller.annotation, 新建类user2Controller.java

    第二处优化: 注意加注解的方式, 类注解和方法注解

    

package com.tgb.web.controller.annotation;import javax.servlet.http.HttpServletRequest;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controller@RequestMapping("/user2")public class User2Controller {	@RequestMapping("/addUser")	public String addUser(HttpServletRequest request){		String result = "this is addUser---------优化版";		request.setAttribute("result", result);		return "/annotation"; 	}	@RequestMapping("/delUser")	public String delUser(HttpServletRequest request){		String result = "this is delUser---------优化版";		request.setAttribute("result", result);		return "/annotation"; 	}		@RequestMapping("/toUser")	public String toUser(){		return "/annotation"; 	}}

 

6. 根据spring-servlet.xml设置, 在/WEB-INF/jsp/下新建  annotation.jsp　　

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>            		  
     
       annotation 注解1 
      
	  
     
      	      	${result }	  
     
  

　

7. IE端访问:    　

http://localhost:8080/springMVC4/user2/addUser

http://localhost:8080/springMVC4/user2/addUser

http://localhost:8080/springMVC4/user2/toUser

 

显示结果: 

annotation 注解1  this is addUser---------
