jsp中获取当前路径

面试中遇到的：

<%@ page contentType="text/html; charset=gb2312" language="java" import="java.io.*" errorPage="" %>







当前WEB应用的物理路径：<%=application.getRealPath("/")%>

当前你求请的JSP文件的物理路径：<%=application.getRealPath(request.getRequestURI())%>

<%
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+"
");
String realPath1 = "http://" + request.getServerName() + ":" + request.getServerPort() + request.getContextPath()+request.getServletPath().substring(0,request.getServletPath().lastIndexOf("/")+1); 
out.println("web URL 路径:"+realPath1);
%>
