Does anyone have a working spring3 securty config using oauth2?

I am trying to make spring security with oauth2 work but there is really no good tutorial out there. The tonr and sparkl example apps magi开发者_如何学Pythoncally work but I won't have a spring client which maybe does some magic. So does anyone have a valid spring3 oauth2 config and/or tutorial plus the client config?

Thanx!
