spring-mvc - SpringMVC在JSP中加载CSS等静态资源问题

问题描述

问 题

大家好，我的问题是这样的。
自己搭建了SpringMVC + Spring + Hibernate 框架。
结果在JSP中引用CSS等静态文件的时候遇到了404的问题。
以下是问题的截图。以及配置文件的信息。

还有就是我查了很多资料。SpringMVC加载静态资源的三种配置我都已经试过了但是都不好使。
比如这个链接的内容 三种方式都不好使。

问题情况如下：

项目结构：

SpringMVC配置文件：

jsp:

<%@ page language="java" contentType="text/html; charset=UTF-8"  pageEncoding="UTF-8"%>

<%
    String path = request.getContextPath();
    String basePath = request.getScheme() + "://"
            + request.getServerName() + ":" + request.getServerPort()
            + path + "/";
%>

  <body>
  
    <h1>WELCOME TO WORKSPACE</h1>
    <img src="WEB-INF/imgs/watch.png" />
    
  </body>
</html>

Controller:

//就只粘贴了有用的部分
package com.whr.Controller;

import java.sql.Date;
import java.util.List;

import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.whr.Entity.Work;
import com.whr.Service.WorkService;

@Controller
@RequestMapping("/work")
public class WorkController {

    @Autowired
    private WorkService workService;
    
    private static Logger logger = Logger.getLogger(WorkController.class);
    
    
    @RequestMapping("/index")
    public String workIndex()
    {
        return "testIndex";
    }
    @RequestMapping("/index2")
    public String workIndex2()
    {
        return "work";
    }

大概情况就是这样的了。
弄了两天了，方法试了好多，简直焦头烂额。各位大神帮帮忙看看吧，不胜感激！

解决方案

静态资源不要放在WEB-INF目录下，WEB-INF目录的所有文件是没法直接访问的，除了jsp可以放在WEB-INF下之外，其他img/css/js都移到WebRoot下吧。
