JSP各种路径的获取

<%@ page contentType="text/html; charset=utf8" 
 	language="java" import="java.io.*" errorPage="" %>
 <html>
 <head>
 <meta http-equiv="Content-Type" content="text/html; charset=utf8">
 <title>Get Paths</title>
 </head>
 
 <body>
 当前WEB应用的物理路径：<%=application.getRealPath("/")%><BR><hr>
 当前你求请的JSP文件的物理路径：<%=application.getRealPath(request.getRequestURI())%><BR><hr>
 <%
 String path=application.getRealPath(request.getRequestURI());
 String dir=new File(path).getParent();
 out.println("当前JSP文件所在目录的物理路径"+dir+"<br><hr><p>");
 
 String realPath1 = "http://" + request.getServerName() + ":" + request.getServerPort() + request.getContextPath()+request.getServletPath().substring(0,request.getServletPath().lastIndexOf("/")+1); 
 out.println("web URL 路径:"+realPath1+"<br><hr>");
 
 String realPath2 = request.getContextPath();
 out.println("getContextPath: "+realPath2+"<br><hr>");
 
 String realPath3 = request.getServletPath().substring(0,request.getServletPath().lastIndexOf("/")+1); 
 out.println("getServletPath: "+realPath3);
 %>
 </body>
 </html>

执行结果：

当前WEB应用的物理路径：F:\115Synchronization\code save\JSP\

当前你求请的JSP文件的物理路径：F:\115Synchronization\code save\JSP\web\web\src\fundation\getPath.jsp

当前JSP文件所在目录的物理路径F:\115Synchronization\code save\JSP\web\web\src\fundation

web URL 路径:http://localhost:8080/web/web/src/fundation/

getContextPath: /web

getServletPath: /web/src/fundation/
