A few months back, I tried several approaches using both Spring 1.2 and 2.0 AOP models but wasn't successful. My goal was to remove my programmatic access control checks from the methods that handled authenticated and anonymous reads (GET) vs authenticated writes (PUT/POST/DELETE) within a single resource. I eventually worked out a solution using Spring Security, but it still bugged me since I wanted to handle some logging as well. As I implemented the fix a while ago, unfortunately I can't provide more detail on the error messages I was seeing. But yes, my general feeling is that it would be nice to see an example that shows how Spring AOP / AspectJ could or should work in Wink.
