jsp中获取当前文件路径详解编程语言

 % 

 String path1 = application.getRealPath(request.getRequestURI()); //当前请求的JSP文件的物理路径 

 String path2 = application.getRealPath("/"); //当前WEB应用的物理路径 

 String path3 = request.getRequestURI(); 

 StringBuffer path4 = request.getRequestURL(); //getRequestURL()返回的是StringBuffer 

 String virtualPath = request.getServletPath(); //虚拟路径 

 String realPath = request.getRealPath(virtualPath);//物理路径 

% 

PS： request.getRequestURI()与request.getRequestURL()的区别
request.getRequestURI()只是显示的是文件的名称  //  /cta/xiahu/xiahu_add.jsp 

request.getRequestURL()显示的全部的URL           //  http://localhost:7001/cta/xiahu/xiahu_add.jsp
