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 |

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、获取服务器根路径

<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获取此次请求URL以及服务器根路径的方法,希望对大家的学习有所帮助。
