I am trying to implement user registration and log in flow | SSO using Spring Security Oauth 2.0 and Google as the authentication provider.
- How should I initiate registration and login flow? What filter needs to be applied?
In registration flow, I will needs user's details (name, email) that are part of successful authorization response, to be persisted in my local database. How do I handle that?
What's the purpose of oauth2:client id="oauth2ClientFilter" ?
This is how my application context file looks like:-

EDIT
I did implemented same use case using Spring Security OpenID by:-
- Declaring openid:form tag with exchange attributed configured
- Extend the UserDetailsService as described here.
I am looking for equivalent configuration for Oauth 2.0.
