jsp路径兼容

jsp头

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<%
String path = request.getContextPath();     //ProjectName
String servPath=request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+"/";//http://localhost:8080/
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
System.out.println(basePath);>>http://localhost:8080/ProjectName
%>

兼容写法：（https是否好用没试过，猜想没有问题：

猜想https环境下request.getScheme()会获取正确的协议？待验证。

<link href="<%=basePath%>/pc/resources6.1/ztree_v3-master/css/demo.css" rel="stylesheet" type="text/css">

绝对路径写法：

<link href="/ProjectName/pc/resources6.1/ztree_v3-master/css/demo.css" rel="stylesheet" type="text/css">

相对路径写法：

<link href="../pc/resources6.1/ztree_v3-master/css/demo.css" rel="stylesheet" type="text/css">
