【Java】获取此次请求URL,获取服务器根路径

一、 获取此次请求的URL

String requestUrl = request.getScheme() //当前链接使用的协议
        +"://" + request.getServerName()//服务器地址  
        + ":" + request.getServerPort() //端口号  
        + request.getContextPath() //应用名称,如果应用名称为
        + request.getServletPath() //请求的相对url  
        + "?" + request.getQueryString(); //请求参数

举例:

http://127.0.0.1:8080/world/index.jsp?name=lilei&sex=1
"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
"" 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、获取服务器根路径

<%  
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>
