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
