constructor using field 후 아래 같은 오류가 뜹니다.

Description:

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

┌─────┐

| securityConfig (field private com.example.demo.oauth.PrincipalOauth2UserService com.example.demo.config.SecurityConfig.principalOauth2UserService)

↑ ↓

| principalOauth2UserService (field private org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder com.example.demo.oauth.PrincipalOauth2UserService.bCyBCryptPasswordEncoder)

└─────┘

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.
