Michael's right. If all you're doing is calling super.oauth1Callback() in the overriding method, then there's really no reason to override that method at all. (But if you do, be sure to annotate the providerId parameter with @PathVariable).
While we're on the topic, I've been wondering for a *long* time about overriding the connectView() method versus having a connectView property that can be configured in Spring. Certainly, overriding connectView() gives more flexibility in the sense that you could construct the returned value intelligently using whatever facilities Java offers...but I also think that the most common case would be a view that is expressed as a simple String (and thus, can be easily configured via Spring injection without creating a subclass of ConnectController). Curious what your thoughts are?
