다음 문제를 해결할 수 없습니다. My Spring + JPA + hibernate + Oracle DB 애플리케이션은 데이터베이스에서 데이터를 올바르게 읽지 만 저장하지는 않습니다. 비슷한 주제로 인터넷 검색 (이 포럼)을 발견했지만 불행히도 내 코드에서 수정할 수 없습니다.JPA entityManager가 데이터를 저장하지 않음, flush가 "progres에서 트랜잭션 없음"예외 발생
생각 중 하나는 persist() 메서드를 호출 한 후에 entityManager.flush()을 추가하는 것이지만 예외는 javax.persistence.TransactionRequiredException: no transaction is in progress입니다.
beginnig에서 나는 또한 내 저장소 클래스에 EntityManagerFactory을 사용했지만 다른 주석을 기반으로 EntityManager과 @PersistenceContext annotation을 사용하도록 마이그레이션했습니다.
도움을 주시면 감사하겠습니다.
