JPA 연관관계 매핑관련 에러좀 부탁드립니다..

안녕하세요.

JPA를 사용하여 회원가입 후 데이터가 정상적으로 DB에 들어 갔는지 확인 하려고 하는데 에러가 발생합니다..

원인은 구글링해서 찾아본 결과 확실하지는 않지만. 아래와 같은 이유인 것 같은데

어떻게 고쳐야하는지 손을 못대겠습니다..

ERROR 1452 : Cannot add or update a child row (a foreign key constraint fails)

외래 키(Foreign Key) 필드에 값을 삽입하거나 수정하려 할 때, 외래 키가 참조하는 주 키(Primary Key)에서 사용하는 값 이외의 값이 들어가면 이 에러를 반환한다.

이 때는 주 키에 속한 값으로 외래 키를 수정하거나 삽입해야 한다.

현재 User(회원) 과 Role(권한)이 다대다 관계로 중간에 매핑테이블을 따로 만들어서 진행하고 있습니다.

회원가입 성공 시 권한을 갖는 회원이 저장되고 User_Role테이블에 회원id와 권한id가 생겨야 합니다.

식별값 id는 전부 @Id 와 @GeneratedValue(strategy = GenerationType.IDENTITY) 적용하였습니다.

User 엔티티 입니다.

Role 엔티티 입니다.

회원 저장기능 부분입니다. (파란 부분이 권한을 생성해서 회원에게 셋 해줍니다.)

application.properties 설정 상태 입니다. (개발 하고 있는 상태라서 create로 주었습니다.)

생성된 테이블 구조 입니다.

매핑테이블 user_role의 외래키 정보 입니다.

실제 에러 코드 입니다. 회원가입을 저장을 누르는 순간 아래 첫줄부터 발생합니다 .

Hibernate: insert into user_role (user_id, role_id) values (?, ?)

사용자 권한 테이블에 권한 아이디 1을 넣을려고 하는데요,
권한 테이블에 권한 아이디 1이 없으니 오류가 발생한 겁니다.
권한 테이블에 데이터를 먼저 넣어둬야겠죠.

안녕하세요 선생님. 답변이 늦어서 정말 죄송합니다ㅠㅠ
위 문제를 아직 해결을 하지 못했습니다..
말씀하신 이류를 원인으로 저도 생각하고 있긴한데 왜 정상적으로 저장이 안되는지 궁금합니다..

저는 User와 Role은 N:M 관계로 사이의 User_Role이라는 매핑테이블을 구상해서 구현했습니다.
User엔티티 와 Role엔티티 관계중 User를 연관관계의 주인으로 설정했고
아래와 같은 서비스 로직의 save()메서드를 보시면
User객체 안에 Role객체를 생성하여 Id를 1L로 주고 User에 넣어 주었거든요..
그리고는 연관관계의 주인인 User의 레포지토리로 save를 실행했는데
연관관계의 주인(user)의 레포지토리를 사용하여 저장쿼리를 실행시켜주면 되는 것 아닌가요?

public User save(User user){ String encodedPassword = passwordEncoder.encode(user.getPassword()); user.setPassword(encodedPassword); user.setEnabled(true); Role role = new Role(); role.setId(1L); user.getRoles().add(role); return userRepository.save(user); }

답변 감사드립니다!!

권한을 정의하는거와 사용자에게 권한을 부여하는 거는 다른 일 입니다.
관리자,운영자,정회원,준회원 정도로 권한을 정의한다고 해보겠습니다.
그럼 이 권한들이 Role 테이블에 데이터로 있어야 합니다.
그래야 사용자와 권한을 매핑 할 수가 있는거죠.
근데 글쓴님은 사용자에게 정의 되지 않은 권한을 부여 하면,
자동으로 권한 정의까지 될 것으로 기대하고 있습니다.
JPA 를 포함한 ORM 들이 이런 걸 알아서 해주지는 않습니다.
Role 테이블에 직접 수동으로 데이터 넣어 두시면 됩니다.

아!!, 제가 지금 이해하고 있는 그대로 말씀해주셨네요
수동으로 직접 권한을 주니 정상적으로 기능들이 동작합니다 감사합니다!

선생님, 말씀해주신 내용을 바탕으로 제가 이해한 내용과 제가 공부한 내용을 정리해보면..
User의 경우는 DB에 직접 붙을 수 있는 UserRepository가 있기 떄문에
user 객체를 생성하고 save()를 할 경우 실제로 DB에 들어가지만.

Role같은 경우는 위의 save() 로직 안에서 Role객체를 생성하고 serId(값)을 준다 하여도 실제 DB에는 Role테이블에 데이터가 없기 때문에 무결성 원칙에 위배되고 해결방법은 수동으로 넣어주어야 된다.

말씀하신 부분을 이렇게 이해했는데 맞는가요?

추가로.. 저 위의 제 로직을 사용하려면 (수동으로 넣지 않고 자동으로 하려면) RoleRepository를 만들어서 save() 로직안에서 roleRepository.save()먼저 해주고 하면 되는 건가요?

질문이 많아서 죄송합니다.. 답변 감사드립니다!!
