9강 까지 구현한 CustomOAuth2UserService

@Service
public class CustomOAuth2UserService extends DefaultOAuth2UserService {

    @Override
    public OAuth2User loadUser(OAuth2UserRequest userRequest) throws OAuth2AuthenticationException {

        OAuth2User oAuth2User = super.loadUser(userRequest);
        System.out.println(oAuth2User);

        String registrationId = userRequest.getClientRegistration().getRegistrationId();
        OAuth2Response oAuth2Response = null;
        if (registrationId.equals("naver")) {

            oAuth2Response = new NaverResponse(oAuth2User.getAttributes());
        }
        else if (registrationId.equals("google")) {

            oAuth2Response = new GoogleResponse(oAuth2User.getAttributes());
        }
        else {

            return null;
        }

        //추후 작성
    }
}

나머지 CustomOAuth2UserService

@Service
public class CustomOAuth2UserService extends DefaultOAuth2UserService {

    @Override
    public OAuth2User loadUser(OAuth2UserRequest userRequest) throws OAuth2AuthenticationException {

        OAuth2User oAuth2User = super.loadUser(userRequest);
        System.out.println(oAuth2User);

        String registrationId = userRequest.getClientRegistration().getRegistrationId();
        OAuth2Response oAuth2Response = null;
        if (registrationId.equals("naver")) {

            oAuth2Response = new NaverResponse(oAuth2User.getAttributes());
        }
        else if (registrationId.equals("google")) {

            oAuth2Response = new GoogleResponse(oAuth2User.getAttributes());
        }
        else {

            return null;
        }
				
				//리소스 서버에서 발급 받은 정보로 사용자를 특정할 아이디값을 만듬
        String username = oAuth2Response.getProvider()+" "+oAuth2Response.getProviderId();

				UserDTO userDTO = new UserDTO();
        userDTO.setUsername(username);
        userDTO.setName(oAuth2Response.getName());
        userDTO.setRole("ROLE_USER");

				return new CustomOAuth2User(userDTO);
    }
}

UserDTO

@Getter
@Setter
public class UserDTO {

    private String role;
    private String name;
    private String username;
}
