[spring, jpa] Cannot add or update a child row: a foreign key constraint fails

mysql의 auto_increment(자동증가)를 기본키로 사용하고 있다.

그런데 jpa에서는 save시 db에 바로 정보가 insert되지 않아

자동증가하는 기본키를 외래키로 바로 사용해야 하는 경우 문제가 된다.

그래서 이때 save를 대신해서 saveAndFlush를 사용할 수 있다.

// Member에 insert
// Member saveEntity = repositoryClass.save(entity);
Member saveEntity = repositoryClass.saveAndFlush(entity);
        
// 권한 저장
if (req.getAuthSeq() != null && req.getAuthSeq() > 0) {
    // Member의 Auth를 insert
    AuthOfMember authOfMemEntity = new AuthOfMember(req.getAuthSeq(), saveEntity.getMemSeq());
    authOfMemberRepositoryClass.save(authOfMemEntity);
}

에러는 2번 라인으로 인해서 발생되므로, 3번과 같이 saveAndFlush를 사용하면

기본키 값을 가져올 수 있다.
