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>
以上就是Java獲取此次請求URL以及服務器根路徑的方法，希望對大家的學習有所幫助。
