When to use Spring OAuth2 vs Cloud Foundry UAA?

Question

Both code bases can provided OAuth2 capabilities. Why should I use one vs the other?

Answer 1

The Spring OAuth2 library has capabilities of turning an application into a full-fledged OAuth2 Authorization Server, which is able to issue its own tokens BUT it still needs and depends upon a central OAuth2 provider for authentication. CF UAA is one such provider.

Facebook or Github are the other such OAuth2 service providers used more commonly for this purpose.
