DB생성 관련해서 질문있습니다

Question

먼저.. 강의의 교안과는 상관없을수도 있어 죄송합니다..ㅠㅠ 바쁘실텐데..  지금 활용강의1 다듣고 들은거를 활용해서 혼자서 영화예매 DB를 생성중에 있습니다.. 사실 DB설계도 익숙치 않아서 설계가 이상한건지.. 코드가 이상한건지 전혀모르겠습니다.. 도대체 어디다 물어봐야할지 몰라서.. 고민하다가 새벽에  이렇게 질문해봅니다.. 혹시 실례가되었을지 모르겠습니다 죄송합니다 ㅠㅠ 대강 이런식으로 설계하였습니다만..  원래는 MOVIE를 RESERVATION 옆에 두려했었는데 강의에서 외래키는 일대다 관계에서 다의 관계에 넣으라고 하셨던지라 THEATER를 저렇게 넣게 되었는데요.. 다름이아니라 저기 저 MOVIE와 THEATER에서 오류가 납니다.. 여기에서  21, 22 ,23줄 MOVIE관련한 코드와 MOVIE에서의 맨 마지막 두줄 THEATER 관련 코드만 사라지만 정상작동하며 DB가 실행이 됩니다. 혹시 외래키 관련해서 문제가 있는것인지 . 대체 왜그러는지는 모르겠는데  계속 밑의 MOVIE에서의 theaters에서 mapping이 잘못되었다고 합니다..

안녕하세요. DenBe님 우선 전체 맥락이 보이도록 질문을 자세히 적어주셔서, 답변드리기가 좋습니다^^ 고맙습니다. 문제는 다음과 같이 고쳐주시면 됩니다. 기존: mappedBy = "movie" 변경: mappedBy = "movies" 서로 양쪽에 있는 연관관계를 찾을 때는 해당 필드명(멤버변수명)을 적어주시면 됩니다^^ 연관관계를 설정하는 자세한 내용은 JPA 기본편 강의에서 자세히 알려드립니다. https://www.inflearn.com/course/ORM-JPA-Basic/lecture/21697?tab=curriculum 감사합니다.
