how to change url pattern in struts action

问题:

domain/Forum_show.action?pg=2&forum=java

How do I rewrite that to:

domain/forum/java/pg/2

回答1:

Use the URL structure you like right from the start. The ability to map to any URL structure is a feature of the Servlet API.

Also, you don't need to have an action extension (the .action part) in Struts2. In my opinion, creating bogus extensions never made sense.

Here are a few pages where I have talked about using Named Variable Pattern Matching in order to provide prettier URLs. I use this technique in all of my Struts2 apps and it yields much nicer URLs similar to your second example.

• NamedVariablePatternMatcher
• Better URLs with Struts2

You may want to check Struts REST Plugin, which purpose is to follow Ruby on Rails URL style (just as you want).

Both are good answers but you can use UrlRewritefilter. In this link there is an example of how to use in a Struts2 application.
