SpringMVC static静态资源访问

学习参考自易百教程

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="prefix" value="/jsp/" /> -->
              <!-- 定义视图后缀 -->
              <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">
    
    <!--<link rel="stylesheet" type="text/css" href="./styles.css">-->

  </head>
  
  <body>
    <h2 style="text-align:center"> my HTML page. </h2>
  </body>
</html>

结果：
