相对网址和绝对网址的区别 [英] relative url and absolute url difference

问题描述

servlet容器中的相对URL和绝对URL有什么区别.例如，如果在webinf文件夹下有一个名为forum.jsp的jsp.当我想将当前请求从同一webinf文件夹下的当前jsp文件分派到jsp时，是以下正确方法

What is the difference between relative and absolute url in servlet container. for example if there is an jsp called forum.jsp under webinf folder. when i want dispatch the current request to the jsp from the current jsp file which is under the same webinf folder, is the following correct way

/forum.jsp

/forum.jsp

相对URL表示相对于web-inf文件夹或jsp位置的相对地址.

relative url means relative to the web-inf folder or to the jsp location.

推荐答案

绝对URL 为:http://stackoverflow.com/questions/3591899/relative-url-and-absolute-url-difference

和相对URL 是:/questions/3591899/relative-url-and-absolute-url-difference

此外， 相对URL 可以只是:../questions/3591899/relative-url-and-absolute-url-difference取决于链接页面的位置...

Also, a relative URL can be just: ../questions/3591899/relative-url-and-absolute-url-difference depending where is the linking page located...

或./3591899/relative-url-and-absolute-url-difference(如果链接页面位于questions文件夹上)

Or ./3591899/relative-url-and-absolute-url-difference if the linking page is located on the questions folder

我建议始终使用相对URL ...，并且努力，继续尝试使用它们...

I will suggest to always use Relative URL... and it goes hard, keep trying to use them...

一个问题，为什么您的JSP位于WEB-INF/文件夹中?

One question, why your JSPs are in the WEB-INF/ folder?

您无权访问WEB-INF文件夹下的JSP，如果尝试访问它，服务器将抛出404 error. J2EE仅在此文件夹下查找类和库.

You don't have access to JSP under the WEB-INF folder, if you try to access it the server will throw a 404 error. J2EE only looks for classes and libraries under this folder.
