1、程序目录如下：

2、web.xml

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns="http://xmlns.jcp.org/xml/ns/javaee"
      xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee 
      http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
       id="WebApp_ID" version="3.1">
      
      <display-name>springMVC_hello</display-name>
      
      <servlet>
      	<servlet-name>dispatcher</servlet-name>
      	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
     	<init-param>
      		<param-name>contextConfigLocation</param-name>
      		<param-value>/WEB-INF/dispatcher-servlet.xml</param-value>
      	</init-param>
      </servlet>
    
    	<servlet-mapping>
    		<servlet-name>dispatcher</servlet-name>
    		<url-pattern>/</url-pattern>
    	</servlet-mapping>
      	
    </web-app>

该配置中<url-pattern>/</url-pattern>拦截了所有路径请求，也包括了所有static静态资源，javascript、css、img等，当需要访问静态的资源文件时，需要在\[servlet-name\]-servlet.xml文件中添加配置<mvc: resources location="" mapping="">完成资源的获取。

<mvc:resources mapping="/javascript/**" location="/static_resources/javascript/"/>  
    <mvc:resources mapping="/styles/**" location="/static_resources/css/"/>  
    <mvc:resources mapping="/images/**" location="/static_resources/images/"/>

3、dispatcher-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:context="http://www.springframework.org/schema/context"
        xmlns:mvc="http://www.springframework.org/schema/mvc"
        xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd
            http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">  
           
           <context:component-scan base-package="com.controller" />
    
           <mvc:default-servlet-handler /> 
           <mvc:annotation-driven />
    	   <mvc:resources location="/html/" mapping="/html/**"/>
    
           <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="internalResourceViewResolver">
                  
                  
                  <property name="suffix" value=".jsp" />
           </bean>
           
    </beans>

4、controller

package com.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    
    @Controller
    public class LinkHTMLController {
    	
    	@RequestMapping(value="/index",method=RequestMethod.GET)
    	public String page(){
    		return "index";	//处理localhost:8080/springMVC_linkToHTML/index的路径请求，并返回index.jsp显示
    	}
    	
    	@RequestMapping(value="/toHtml",method=RequestMethod.POST)
    	public String toHtml(){
    		System.out.println("toHtml");
    		return "redirect:/html/MyHtml.html";//当前return路径localhost:8080/springMVC_linkToHTML
    	}
    }

5、index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
    	<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
    	<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
    	<html>
    	  <head>   
    	    <title>link to a html</title>
    	  </head>
    	  
    	  <body>
    	   <h2>Loading a html page.</h2>
    	   <form:form action="/springMVC_linkToHTML/toHtml">
    	   		<button type="submit">get a html</button>
    	   </form:form>
    	  </body>
    	</html>

6、MyHtml.html

<!DOCTYPE html>
    <html>
      <head>
        <title>MyHtml.html</title>
    	
        <meta name="keywords" content="keyword1,keyword2,keyword3">
        <meta name="description" content="this is my page">
        <meta name="content-type" content="text/html; charset=UTF-8">
        
        
    
      </head>
      
      <body>
        <h2 style="text-align:center"> my HTML page. </h2>
      </body>
    </html>

结果：
