由于要导入好多js文件和cs文件，并且每个页面都需要导入，所以我把公共的导入js和css文件放在了一个jsp里面，在用到的里面直接导入即可，
此项目用到的js文件下载：这里
用到的css文件的下载：这里
公共的导入外部js和css的jsp（commTop.jsp）
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<link rel="stylesheet" type="text/css" href="<%=path %>/easyui/css/demo.css">
<link rel="stylesheet" type="text/css" href="<%=path %>/easyui/themes/black/easyui.css">
<link rel="stylesheet" type="text/css" href="<%=path %>/easyui/themes/icon.css">
<script type="text/javascript" src="<%=path %>/js/jquery-1.8.0.min.js"></script>
<script type="text/javascript" src="<%=path %>/js/jquery.easyui.min.js"></script>
<script type="text/javascript" src="<%=path %>/js/easyui-lang-zh_CN.js"></script>
接下来进入首页index.jsp：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@include file="commTop.jsp"%>
