从Request对象中可以获取各种路科乙落径信息，以下例子：假设请求的页面是index.jsp,项目是WebDemo，问答则在index.jsp中获取有关request对象的各种路径信息如下Stringpath=request.getContextPath();StringbasePath=request.getScheme()+"://"+request.getServerName()+":"+request.getServer抗孩其化多市是Port()+path+"/";StringremoteAddress=request.getRemoteAddr();StringservletPa钟县族th=reque字st.getServletPath();StringrealPath=request.getRealPath("/");StringremoteUser=request.getRemoteUser();StringrequestURI=request.getRequestURI();out.println("p换空清运素突元ath:"+path+"<br>");out.println("basePath:"+basePath+"<br>");out.println("remoteAddr:"+remoteAddress+"<b吸苦确扩巴境植回算语r>");out.pri剧杆汉ntln("servletPath:"+servletPath+"<br>");out.println("realPath:"+realPath+"<br>");out.prin粒生办以减帮牛线tln("remoteUser:"+remoteUser+"<br>");out.println("requestURI:"+reque采示置倍以损属极环掌刘stURI+"<br>");结果：path:/WebDemobasePath:http://localhost:8683/额视沙龙度千皮仍青执充WebDemo/remoteAddr:127.0.0.1servletPath:/index.jsprealPath:D:\apache-tomcat-6.0.13\webapp于影s\WebDemo\remoteUser:nullrequestURI:/WebDemo/index.jsp从上不难看出request各个对应方法所代表的含义从request获取各种路径总结：requ蒸充所任est.getRealPath("url");//虚拟目录映射为实际目录request.getRealPath(".程司状收义/");//网页所在的目录r破滑课服交互少也胶损equest.getRealPath("../");//网页所在目录的上一层目录假定你的webapplication(web应用)名称为news，你的浏找究情览器中输入请求路径：http://localhost:8密丝派补制再源兵080/uploading/load.jsprequest.getContextPath()=>/uploadingrequest.getServletPath()=>/load.jsprequest.getRequestURL()=>http://localhost:8080/uploading/load.jsprequest.getRealPath("/")=>F:\learn\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\uploading\现在request.getRealPath("/")这个方法已经不推荐使用了可以使用ServletContext.getRealPath(java.lang.String)instead.request.getSession().getServletContext().getRealPath()得到工程文件的实际物理路径,也就是绝对地址//Returnsthepartofthisrequest'sURLfromtheprotocolnameuptothequerystringinthefirstlineoftheHTTPrequest//eg./manage/editExam.domethod=goExamSet&type=UStringurl=request.getRequestURI();//ThereturnedURLcontainsaprotocol,servername,portnumber,andserverpath,butitdoesnotincludequerystringparameters//eg.http://127.0.0.1:8080/manage/editExam.domethod=goExamSet&type=UStringBufferurl_buffer=request.getRequestURL();HttpServletRequest的这两种方法都只能得到不包含参数的请求url，区别如下：1前者返回相对路径，后者返回完整路径2前者返回string，后者返回stringbuffer得到完整请求url可以通过如下方法，getQueryString()得到的是url后面的参数串，和前者相加就是带参数的请求路径了StringqueryString=request.getQueryString();ringfullPath=url+queryString;//或者是url_buffer.toString()+queryString;以上就是小编为大家带来的jspRequest获取url信息的各种方法对比的全部内容了，希望对大家有所帮助，多多支持脚本之家~
