Class OAuth2UserInfoFactory

java.lang.Object

com.alpaca.security.oauth2.userinfo.OAuth2UserInfoFactory

public class OAuth2UserInfoFactory
extends Object

Factory for creating provider-specific OAuth2 user information handlers.

This class follows the Factory design pattern by encapsulating the logic to instantiate an appropriate OAuth2UserInfo subclass based on the OAuth2 provider identified by registrationId.

Current implementation supports:

• google — returns an instance of GoogleUserInfo.

If the registrationId does not match a supported provider, a BadRequestException is thrown with a descriptive error message.

• BadRequestException
