    1.新建demo4  web项目, 导入spring包(使用的是spring4.2)

    2.修改WEB-INF下的WEB.XML内容为

    <?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">
       
        <servlet>  
         <servlet-name>dispatch</servlet-name>  
         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
         <init-param>  
          <param-name>contextConfigLocation</param-name>  
          <param-value>/WEB-INF/spring-servlet.xml</param-value>  
         </init-param>  
         <load-on-startup>1</load-on-startup>  
        </servlet>  
        <servlet-mapping>  
         <servlet-name>dispatch</servlet-name>  
         <url-pattern>*.do</url-pattern>  
        </servlet-mapping>  
      <welcome-file-list>  
        <welcome-file>index.jsp</welcome-file>  
      </welcome-file-list>  
    </web-app>
    View Code

    3.在WEB-INF下的新建spring-servlet.xml,内容为

    <?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:util="http://www.springframework.org/schema/util" xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="
      http://www.springframework.org/schema/beans
      http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
      http://www.springframework.org/schema/util
      http://www.springframework.org/schema/util/spring-util-4.2.xsd
      http://www.springframework.org/schema/context 
      http://www.springframework.org/schema/context/spring-context-4.2.xsd
      http://www.springframework.org/schema/mvc
      http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd">
      
               <context:component-scan base-package="com"></context:component-scan>   
                <mvc:annotation-driven />  
                <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
            <property name="prefix" value="/WEB-INF/jsp/"/>  
            <property name="suffix" value=".jsp"/>  
            <property name="viewClass"  
                    value="org.springframework.web.servlet.view.JstlView" />  
            </bean>  
          </beans>  
    View Code

    4.在SRC下新建 包  com.game.controller

    5.在该包下新建类

    package com.game.controller;
    
    import java.io.IOException;
    import java.util.Date;
    
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.servlet.ModelAndView;
    
    @Controller
    public class Helloworld {
    
        @RequestMapping("/helloworlda")  //此处控制浏览器里访问路径 具体为:/SpringDemo/helloworld
        public void helloWorld(HttpServletRequest request, HttpServletResponse response) throws IOException {
            
            //输出字符串
            response.getWriter().append("hello world--a");
    
        }
        
      
        @RequestMapping("home")  
        public ModelAndView home(){  
            ModelAndView mv=new ModelAndView();
            mv.addObject("name","xiaoxiao");
             mv.getModel().put("age", "111110");
            return mv;
        }  
        
     
        
    }
    View Code

    6.在web-inf下新建名为jsp的文件夹,并新建home.jsP文件,内容为

    <%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
    <%
    String path = request.getContextPath();
    String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
    %>
    
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
    <html>
      <head>
        <base href="<%=basePath%>">
        
        <title>My JSP 'home.jsp' starting page</title>
        
        <meta http-equiv="pragma" content="no-cache">
        <meta http-equiv="cache-control" content="no-cache">
        <meta http-equiv="expires" content="0">    
        <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
        <meta http-equiv="description" content="This is my page">
        <!--
        <link rel="stylesheet" type="text/css" href="styles.css">
        -->
    
      </head>
      
      <body>
        This is my JSP page. ${age} ==${name} }<br>
