***************************
APPLICATION FAILED TO START
***************************

Description:

The dependencies of some of the beans in the application context form a cycle:

┌─────┐
|  oauth2UserService defined in file [D:\GooGoo\out\production\classes\eunhye\GooGoo\config\oauth\Oauth2UserService.class]
↑     ↓
|  securityConfig defined in file [D:\GooGoo\out\production\classes\eunhye\GooGoo\config\security\SecurityConfig.class]
└─────┘


Action:

Relying upon circular references is discouraged and they are prohibited by default. Update your application to remove the dependency cycle between beans. As a last resort, it may be possible to break the cycle automatically by setting spring.main.allow-circular-references to true.


Process finished with exit code 1

oauth2UserService와 securityConfig가 cycle을 이루고 있다.

뭔가 구조가 잘못됐다는 것을 알 수 있었습니다만...

전 강의 잘 듣고 잘 코드 쳤다고 생각이 되거든요ㅠ

스스로를 의심하며 아무리 코드를 쳐다봐도 잘못된 점을 모르겠어서 질문 올립니다.

다음은 관련된 코드들입니다.
