Question

Is it possible to restrict access to certain URLs in Struts 2? I already have it so you can’t access jsp’s directly, but you can access them indirectly. For example if I have a jsp “blah.jsp” I can access it by typing “/blah” and if I don’t have an Action called Blah.java, it will automatically go to the result, blah.jsp. Most of the time this is what I want, but there will be some jsps that I don’t want to be access this way, like “blah-success.jsp”. Is there a way to say that, I can’t navigate to any url’s that look like “/-success”?

Edit:
I almost have it working…

    <constant name="struts.enable.SlashesInActionNames" value="true"/>

<package name="my-secure-url" extends="my-secure" namespace="/secure**">
    <action name="*"> 
        <interceptor-ref name="secureStack"/>
        <result>{1}</result>
    </action> 
</package>

This works if I try to visit “/secure/anything/anything/etc” and I’m not logged in, I get directed to the login page. However if I just logged in and I’m at “http://localhost:8080/Struts2NewChapter8/secure/admin-portfolio” and I click a link to “http://localhost:8080/Struts2NewChapter8/secure/update/update-account-form” I get errors that look like this:

Answer 1

But of course. Struts matches wildcard mappings in the order they appear in your config file, so the last one that matches a request will be the one used (i.e. less specific matches must be before more specific matches).

Something like this should do the trick:

 <action name="*">
   <result>/WEB-INF/jsp/{1}.ftl</result>
 </action>  

 <action name="*-success">
   <result>/WEB-INF/jsp/access-denied.jsp</result>
 </action>  

The above will keep your current behaviour and cause any file with a -success suffix in the name to end up at access-denied.jsp.

Edit: You’ll need to enable this property to have slashes in your action names:

<constant name="struts.enable.SlashesInActionNames" value="true"/>

To make it conditional, I would use an interceptor stack that checked if a user was logged in before forwarding to the .jsp:

 <action name="secure/*">
   <interceptor-ref name="authenticationStack"/>  
   <result>/WEB-INF/jsp/{1}.jsp</result>
 </action> 

In your authenticationStack you would need an Interceptor that determines if a user is logged in. If not you would forward them to an access-denied.jsp type page from within the interceptor. The Struts docs on Interceptors should help you out.
