spring MVC 项目 WEB-INF下的jsp不能加载css文件

一.项目目录

二.解决方法(已解决)

1. jsp文件加入

<link href="<c:url value="/css/main.css" />" rel="stylesheet"  type="text/css" />

或

<link rel="stylesheet" href="/app18b/css/main.css" type="text/css"><!-- app18b为项目名->

或

<style>
    @import url("/app18b/css/main.css");
</style>

2.此时的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
