我们何时何地在struts1中编写“ url.do”

Question

I have seen a couple of files in which we sometimes use the "url.jsp" but there are sometimes when we use "url.do" in the struts-config file in struts-1 . Can anyone explain what do we actually mean by writing this ".do" in the URL.

Answer 1

If you want to redirect the control to a different action, we need to use the eg redirectAction.do

There should be a corresponding action-mapping with path /redirectAction present which would then pass on the control to that action.

Also, this .do is default URL pattern for Struts 1. The same can be changed in "web.xml" file under the node <servlet-mapping> . eg <url-pattern>*.do</url-pattern>

Answer 2

.do is the default Struts 1 URL mapping extension.

You use it when you need to reference an action, eg, a redirect.
