나는 Hibernate/JPA에서 작동 시키려고하는 간단한 클래스 계층 구조를 가지고있다.2 개의 테이블 중 최대 절전 모드 엔티티 분할하기
기본적으로 내가 원하는 것은 MovementData가 데이터베이스의 주요 차량 테이블의 정수 ID에 FK를 사용하여 자체 테이블에 있어야한다는 것입니다.
내가 잘못 했나요? 비슷한 다른 것을 어떻게 달성 할 수 있습니까? 나는 JPA 스펙을 따르고 있다고 확신한다. (동작에서 EJB3이 작동합니다 말한다 : 여기에
EJB3 In Action: @SecondaryTable 내가 점점 오전 예외의 일부입니다 :
여기SEVERE: an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session)
