request获取各种路径总结

从request获取各种路径总结：

request.getRealPath("url");//虚拟目录映射为实际目录

request.getRealPath("./");//网页所在的目录

request.getRealPath("../");//网页所在目录的上一层目录

 

 

假定你的web application(web应用)名称为news，你的浏览器中输入请求路径：

 

http://localhost:8080/uploading/load.jsp

 

request.getContextPath()  =>  /uploading

 

request.getServletPath()  =>  /load.jsp

 

request.getRequestURL()  =>  http://localhost:8080/uploading/load.jsp

 

request.getRealPath("/")  =>   F:\learn\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\uploading\
