question about interceptors

[Darren James <jd...@netflix.com>]

Hi all,

I'm new to struts2 and have some questions about configuring Interceptors.

If your action does not define an interceptor does it get the default 
one (i.e. "defaultStack")?

e.g.
        <action name="MyAction" class="....">   // does this action get 
the struts2 default interceptor stack
            <result>/myAction.jsjp</result>
        </action>

also, if your action *does* define an interceptor, does that augment the 
default one or override it?

e.g.
        <action name="MyAction" class="...">
            <interceptor-ref name="myinterceptor"/>  // do i get 
defaultStack, or did i just override it?
            <result>/myAction.jsp</result>
        </action>


thanks,

- darren.

Override.

You need to include another <interceptor-ref.../> element if you want the
default stack in addition to the "myinterceptor" interceptor. (Or define an
interceptor stack with your interceptor in it, etc.)
