- 83 | @MappedSuperclass /mappedSuperclass = 상속을 하면서 부모클래스의 필드를 모두 가져온다. 84 | 패키지 이름 : com.example.mapping.mappedsuperclass 85 | @PrePersist, @PreUpdate 어노테이션을 BasicEntity에 포함.(petri님 소스 참고) 86 | 87 |
- 88 | 상속매핑(단일테이블) : /inheritanceSingle = 각각의 상속을 단일테이블로 묶는다 89 | 패키지 이름 : com.example.mapping.inheritance.singletable 90 | 91 |
