1.事先准备好所需要的jar包，如下：(commons-logging.jar是必须的)

2.修改WEB-INF目录下的 web.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.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>

3.在WEB-INF目录下新建一个spring-servlet.xml文件，这个文件的名字可以随便，比如：applicationContext-servlet.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:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
        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">
       
       <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>

4.在src目录下新建一个包，比如取名：web

5.在web包中新建一个java类，比如：HomeController

package com;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HomeController {
	
	@RequestMapping("home")
	public String home(){
		return "home";
	}
}

6.在WEB-INF目录下新建jsp目录，在下面新建一个home.jsp文件

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE html>
<html>
  <head>
  </head>
  <body>
    hello ,this is a spring mvc demo!!
  </body>
</html>

7，本人用resin3.1做web服务器，在conf/resin.conf文件中配置如下：(如果用tomcat做web容器也可以，那下面步骤可以略去)

 <host id="second.com" root-directory=".">
       <web-app id='/' document-directory="E:/myeclipse_workspace/Four/WebRoot">
         <stdout-log path='E:/myeclipse_workspace/Four/logs/stdout.log' rollover-period='1W'/>
         <stderr-log path='E:/myeclipse_workspace/Four/logs/stderr.log' rollover-period='1W'/>
         <class-loader>
            <compiling-loader path='E:/myeclipse_workspace/Four/WebRoot/WEB-INF/classes'/>
            <library-loader path='E:/myeclipse_workspace/Four/WebRoot/WEB-INF/lib'/>
         </class-loader>

         <servlet-mapping url-pattern="/servlet/*" servlet-name="invoker"/>

            <session-config> <session-max>4096</session-max>
                <session-timeout>60</session-timeout> <enable-cookies>true</enable-cookies>
               <enable-url-rewriting>true</enable-url-rewriting>
                <always-save-session>true</always-save-session> </session-config>

       </web-app>
   </host>

8.要想本机能解析到 second.com这个域名是本机上的web服务，还得修改下 hosts文件，在里面加上一句

127.0.0.1 second.com

9.测试一下：http://second.com/home.do
