Hibernate 매핑 예외 : 알 수없는 엔티티

Question

나는 Java에 익숙하지 않고 온라인 자습서에서 Hibernate를 배우기 시작했다. 내가 최대 절전 모드와 자바 코드를 만들었지 만 그 후에 나는 테스트를 실패했습니다. MySQL 데이터베이스 "test"에 데이터베이스 테이블 "users"가 있습니다. 레코드를 삽입하려고하면이 오류가 발생합니다.

user.hbm.xml의 'entity-name'속성을 제거하십시오. 그것은 잘 작동합니다. 은 "= 클래스 이름"in.shivasoft.pojo.Users "테이블 ="사용자 "당신은 당신이 '개체 이름이'이름 속성 것을 제거해야하는 이유를 알 수 줘야
