I have a self-join table with a head table and I am using Spring JPA with Hibernate.
My table B entity is like that:
@Entity
public class Table B {
....
@OneToMany
List<TableB> child;
@ManyToOne
TableB parent;
@ManyToOne
TableA topParent;
....
}
I usually get errors because the TableB sub-line is usually lost the TableA value. Of course, I should set TableA value in every TableB object but do I have any annotation or solution to automatically ensure the TableA will not miss?
