자바 jpa 같은 세션에 오브젝트가 있다는 오류 입니다...

Question

안녕하세요 이제 막 jpa강의를 들으면서 공부하게 된 신입입니다... 프로젝트 관리 목적으로 토이 프로젝트 만들어 보는 중 인터넷에 찾아보다 정말 모르겠어서 선배님들께 질문 드리고 싶어서 글을 적어봅니다... org.hibernate.NonUniqueObjectException: A different object with the same identifier

해당 오류는 같은 세션에 같은 오브젝트가 있어서 해당 오브 젝트를 재사용 해야 한다고 인터넷 글을 보았는데 디버그도 찍어서 for (Project project : projects) { project.setUpperPrjctId(upperPrjctId); projectRepository.saveProjects(project); for (Charger charger : chargers.get(index)) { chargerRepository.saveCharger(charger); } index++; } 이부분에서 위에서 프로젝트 저장하고 아래서 charger 저장할때 프로젝트 오브젝트가 두개 있는걸 알았지만 어떻게 재사용해야 할지를 모르겠어서 질문 드립니다. package Ocean.Pms.domain;
