Yes.

Either do it at the start of each method (use 
RequestFactoryServlet.getThreadLocalRequest().getUserPrincipal() to get the 
current user).
Or create a ServiceLayerDecorator and override the invoke(Method,Object...) 
method to add the check (probably based on some annotation on the method).
I believe you could also use "standard AOP" (Spring AOP or Guice AOP, 
probably also AspectJ or similar) on your services.

We use the second approach, it works very well.
