1、新建java dynamic web project，将springmvc3.0所需jar包放到WEB-INF/lib下。

2、web.xml文件

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

<display-name>masterSpringMvc</display-name>

<welcome-file-list>
<welcome-file>index.html</welcome-file>
</welcome-file-list>

<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>

</web-app>
3、springmvc配置文件springmvc.xml

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
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">

<context:component-scan base-package="com.zls.master.springmvc.controller" />

<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix">

<value>/WEB-INF/vm/</value>
</property>
<property name="suffix">
<value>.vm</value>
</property>
</bean>

</beans>
4、controller

package com.zls.master.springmvc.controller;

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

@Controller
public class HomeController {

@RequestMapping("/home.htm")
public ModelAndView home(){
return new ModelAndView("home");
}

}
5、index.html

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
this is index page.
</body>
</html>
6、home.htm只有一句话

this is home page.
7、访问http://localhost:8080/masterSpringMvc/index.html
由于这个请求没有被dispatcherServlet（springmvc）拦截，又在WEB-INF外，所以直接返回了。

8、访问http://localhost:8080/masterSpringMvc/home.htm
