我应该如何在jsp页面中获取根文件夹路径 [英] how should I get root folder path in jsp page

问题描述

我想检索web应用程序的根路径，然后我想追加链接到根路径。
我尝试了request.context，但它返回http：// localhost：8080 / webapp / web-inf。

例如，我的根文件夹路径是

  path = http：// localhost：8080 / webapp / 
  

并且我想追加剩余的链接到这个路径

  helpPath = /help/page/help.htm 
 
 
< a href =$ {path} + $ {helpPath}target =_ blank> name< / a> 
  

任何帮助或指针真的很感谢。

解决方案

 <％= request.getContextPath（）％> 
  

会为您提供您的应用程序的根路径，因此在您的情况下它将会是 http：// localhost：8080 / webapp

根据评论

 <％= request.getContextPath（）％> /help/page/help.htm 
  

会给你你的页面$ / b>

I want to retrieve root path of webapplication, then I want to append link to root path. I tried request.context but it returns "http://localhost:8080/webapp/web-inf".

For example my root folder path is

path  =  http://localhost:8080/webapp/

and I want to append remaining link to this path

helpPath= /help/page/help.htm


<a  href="${path} + ${helpPath}" target="_blank">name</a>

Any help or pointer really appreciated.

解决方案

<%=request.getContextPath()%> 

will give you the rootpath of your application so in your case it will be http://localhost:8080/webapp

As per comment:

<%=request.getContextPath()%>/help/page/help.htm 

will give you your page
