User Registration & Login | SSO using Spring Security OAuth 2.0

问题

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.

回答1:

did you register your client-app in Google? this is how oAuth2 works... the client should be registered in the provider, and get a client ID and client secret. in your XML, it seems like you did not register:

client-secret="client-secret-here"

have a read at Google oAuth2 docs

UPDATE

As for your updated question, I think that the behavior that you see is due to the fact that your application should allow access to "/oauth2/google", in your security.xml file.
