How to implement Oauth login in android+ spring boot+ security

Question

I am trying to implement sns login with Spring Security. The api server is spring-boot and the front is android and iOS.

From my understanding, it seems that spring-security-oauth-client supports the process of issuing an access token with server side rendering. (authentication code grant or implicit grant ..etc)

This is where my troubles begin.

First of all, I want to use OpenId Connect because I know that authentication should not be processed with oauth's access token.

Because android needs to use the sdk, the front (android) issues the idToken and gives it to the backend server.

So I wanted to implement it using the oauth2 function supported by spring-security, but I couldn't find a good way. So the following question arose:

1. Can it be implemented with the oauth-support function of spring-security?

So, I am trying to process authentication by creating an Authentication Provider for each oauth provider through a custom filter that directly extends OncePerRequestFilter.

Another question arises here.

2. Is there any difference between implementing the filter directly in spring-security and performing authentication in the controller of the spring container? performance or other aspects

thank you.
