Using Interceptor to validate user access privilege

Question

I am trying to use an Interceptor to restrict users from performing certain actions.

ContainsKeyInterceptor:

Answer 1

Based on this I don't think the interceptor itself can / needs to be session aware.

You can access this property as such:

final ActionContext context = actionInvocation.getInvocationContext();  
this.session = context.getSession();  

There may be a way to get this set automatically, I'm not too familiar with struts2, but it could be that the sessionaware only works for a specific subset of objects and this interceptor isn't one of them for some reason. (not being scanned, being excluded from scan, of the wrong type)
