原代码：
webroot/index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ page language="java" import="foo" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<html>
<head>
<base href="<%=basePath%>">
