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
