springMVC 静态文件 访问

时间：2021-11-27 06:56:36

1. 新建web project

2. 导入所需jar包

3. 更改web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="3.0"

	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_3_0.xsd">

  <display-name></display-name>

  <welcome-file-list>

    <welcome-file>index.jsp</welcome-file>

  </welcome-file-list>

  <servlet>

  	<servlet-name>springMVC</servlet-name>

  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

  	<init-param>

  		<param-name>contextConfigLocation</param-name>

  		<param-value>classpath*:config/spring-servlet.xml</param-value>

  	</init-param>

  	<load-on-startup>1</load-on-startup>

  </servlet>

  <servlet-mapping>

  	<servlet-name>springMVC</servlet-name>

  	<url-pattern>/</url-pattern>

  </servlet-mapping>

</web-app>

4. 创建config 包, 新建spring-servlet.xml, 添加如下语句

　　<mvc:resources location="/img/" mapping="/img/**"/>

<?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:p="http://www.springframework.org/schema/p"

    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-3.0.xsd

           http://www.springframework.org/schema/context

           http://www.springframework.org/schema/context/spring-context-3.0.xsd

           http://www.springframework.org/schema/mvc

           http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> 

     <context:component-scan base-package="com.tgb.web.controller" />     

     <bean name="/test1/img" class="com.tgb.web.controller.StaticController">

    	<property name="methodNameResolver">

    		<ref bean="paramMethodResolver"/>

    	</property>

    </bean>

    <!-- 静态资源访问 -->

    <mvc:resources location="/img/" mapping="/img/**"/>

    <bean id="paramMethodResolver" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">

    	<property name="paramName" value="do"></property>

    </bean>

    <!-- ViewResolver 视图解析器 -->

    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <property name="prefix" value="/"/>

        <property name="suffix" value=".jsp"/>

    </bean>

</beans>

　5. 新建controller包, com.tgb.web.controller,                              新建StaticController.java

package com.tgb.web.controller;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;

import org.springframework.web.servlet.mvc.multiaction.MultiActionController;

public class StaticController extends MultiActionController{

	public ModelAndView img(HttpServletRequest request, HttpServletResponse response){

		return new ModelAndView("/staticFile");

	}

}

6. 新建staticFile.jsp, 目录在webroot下

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

  <head>

    <title>My JSP 'staticFile.jsp' starting page</title>

  </head>

  <body>

      <h> 图片访问 </h> <br>

      <div>

      	<img alt="图片" src="${pageContext.request.contextPath}/img/a.jpg">

      </div>

  </body>

  </body>

</html>

7. webroot下新建img文件夹, 放入a.jpg文件

8. IE输入网址测试

http://localhost:8080/springMVC2/test1/img?do=img

　　

  • 如果要访问jquery文件的话, 在spring-servlet.xml里加入
  <mvc:resources location="/js/" mapping="/js/**"/>

然后新建一个jquery.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

  <head>

  <script type="text/javascript" src="../js/jquery-1.4.2.min.js"></script>

    <title>My JSP 'jquery.jsp' starting page</title>

    <script type="text/javascript">

    	$(document).ready(function(){

    		alert("jquery");

    	})

    </script>

  </head>

  <body>

      <h> jquery请求 </h> <br>

  </body>

  </body>

</html>

　　

staticController.java

package com.tgb.web.controller;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;

import org.springframework.web.servlet.mvc.multiaction.MultiActionController;

public class StaticController extends MultiActionController{

	public ModelAndView img(HttpServletRequest request, HttpServletResponse response){

		return new ModelAndView("/staticFile");

	}

	public ModelAndView jquery(HttpServletRequest request, HttpServletResponse response){

		return new ModelAndView("/jquery");

	}

}
