本文介紹了Java獲取此次請求URL以及獲取服務器根路徑的方法，並且進行舉例說明，感興趣的朋友可以學習借鑒下文的內容。
一、 獲取此次請求的URL
String requestUrl = request.getScheme() //當前鏈接使用的協議 +"://" + request.getServerName()//服務器地址 + ":" + request.getServerPort() //端口號 + request.getContextPath() //應用名稱，如果應用名稱為 + request.getServletPath() //請求的相對url + "?" + request.getQueryString(); //請求參數
舉例：
http://127.0.0.1:8080/world/index.jsp?name=lilei&sex=1 <Context path="world" docBase="/home/webapps" debug="0" reloadable="true"/> request.getScheme() = "http"; request.getServerName() = "127.0.0.1"; request.getServerPort()= "8080"; request.getContextPath() = "world"; request.getServletPath() = "index.jsp"; request.getQueryString() = "name=lilei&sex=1"; http://127.0.0.1:8080/world/index.jsp?name=lilei&sex=1 <Context path="" docBase="/home/webapps" debug="0" reloadable="true"/> request.getScheme() = "http"; request.getServerName()= "127.0.0.1"; request.getServerPort() = "8080"; request.getContextPath() = ""; request.getServletPath() = "world/index.jsp"; request.getQueryString() = "name=lilei&sex=1";
二、獲取服務器根路徑
<% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %>
使用如下：
<head> <link rel="stylesheet" type="text/css" href="<%=basePath%>static/css/framework/themes/default/easyui.css"> <link rel="stylesheet" type="text/css" href="<%=basePath%>static/css/framework/themes/icon.css"> <link rel="stylesheet" type="text/css" href="<%=basePath%>static/css/base.css"> <script src="<%=basePath%>static/javascript/framework/jquery.min.js"></script> <script src="<%=basePath%>static/javascript/framework/jquery.easyui.min.js"></script> <script src="<%=basePath%>static/javascript/framework/easyui-lang-zh_CN.js"></script> <script src="<%=basePath%>static/javascript/framework/easyui-util.js"></script> </head>
