本文结合个人实验与网上资料整合@http://blog.csdn.net/snannan_268/article/details/5511614


String path = new File(application.getRealPath(request.getServletPath() )).getParent();   //路径获取jsp文件绝对路径


jsp亲测

--ROOT/player.jsp

<%@page language="java" contentType="text/html;charset=utf-8"%>

<%@page language="java" contentType="text/html;charset=utf-8" pageEncoding="utf-8"%>
<%@page import="java.io.*"%>

<%
String path = new File(application.getRealPath(request.getServletPath() )).getParent(); //路径
out.println(path+" "+request.getServletPath()+"<br/>" );
out.println(System.getProperty("user.dir")+"<br/>");
out.println("-------------------------<br/>");
File directory = new File("");//设定为当前文件夹

out.println(directory.getCanonicalPath()+"<br/>");//获取标准的路径
out.println(directory.getAbsolutePath()+"<br/>");//获取绝对路径
out.println("-------------------------<br/>");
directory = new File("abc");
out.println(directory.getCanonicalPath()+"<br/>");//获取标准的路径
out.println(directory.getAbsolutePath()+"<br/>");//获取绝对路径
out.println(directory.getPath()+"<br/>");//获取标准的路径
out.println("-------------------------<br/>");
directory = new File(".");
out.println(directory.getCanonicalPath()+"<br/>");//获取标准的路径
out.println(directory.getAbsolutePath()+"<br/>");//获取绝对路径
out.println(directory.getPath()+"<br/>");//获取标准的路径
out.println("-------------------------<br/>");
directory = new File("..");
out.println(directory.getCanonicalPath()+"<br/>");//获取标准的路径
out.println(directory.getAbsolutePath()+"<br/>");//获取绝对路径
out.println(directory.getPath()+"<br/>");//获取标准的路径

out.println("-------------------------<br/>");//<span style="color: rgb(51, 51, 51); font-family: Arial; font-size: 14px; line-height: 26px;">.jsp中取得路径:</span><span style="color: rgb(51, 51, 51); font-family: Arial; font-size: 14px; line-height: 26px;">3.在Servlet中取得路径: </span>

out.println(request.getRequestURI() +"<br/>");
out.println(request.getContextPath() +"<br/>");
out.println(request.getServletPath() +"<br/>");
out.println(application.getRealPath("player.jsp") +"<br/>");
out.println(new File(application.getRealPath(request.getRequestURI())).getParent() +"<br/>");
out.println(request.getSession().getServletContext().getRealPath("") +"<br/>");<span style="font-family: Arial;">//3.在Servlet中取得路径: </span>
out.println(request.getRequestURL() +"<br/>");

%>

结果如下
