I have a resource server application for which I want to define a controller that needs to get hold of additional information from OAuth2AccessToken. The additional information in the token are added using the authorization server's TokenEnhancer. However, I'm not really sure which part of the whole Spring OAuth 2 configuration I can use for this. I'm using a RemoteTokenServices in my application, which provides a readAccessToken method. However, when I try to use it, I get UnsupportedOperationException.

What information specifically are you needing? What does the enhancement look like? – chrylis -cautiouslyoptimistic- Dec 12 '16 at 08:13

I've added a few user-related details in the token, like UUID, etc. – Psycho Punch Dec 12 '16 at 08:15

Is there a reason not to grab that off of the `@AuthenticationPrincipal`? – chrylis -cautiouslyoptimistic- Dec 12 '16 at 08:17

1The `AuthenticationPrincipal` is an instance of `UserDetails`, which does not have the extra details I need. I actually also have a [different issue](http://stackoverflow.com/questions/41086182/how-do-i-map-oauth-2-token-to-userdetails-object-in-a-resource-server) mapping the `AuthenticationPrincipal` to my custom `UserDetails` class. – Psycho Punch Dec 12 '16 at 08:20
