Code demo
@Entity
public class Category {
....
@OneToMany(mappedBy = "category", fetch=FetchType.LAZY ,orphanRemoval=true)
private List<News> news;
}
Ly do lỗi
Trường hợp này, bạn đang sử dụng quan hệ many to one cũng như đang sử dụng orphanRemoval=true, vậy nên khi bạn sử dụng orphanRemoval nó sẽ truy vấn đến đối tượng news. Trong trường hợp này như các bạn thấy rằng news vẫn có giá trị đang null. Vì lý do này nên nó thông báo lỗi như dòng trên:
A collection with cascade=”all-delete-orphan” was no longer referenced by the owning entity instance
Khắc phục
Để khắc phục lỗi trên, các bạn sử chỉ cần khởi tạo đối tượng ban đầu cho news như sau:
@Entity
public class Category {
....
@OneToMany(mappedBy = "category", fetch=FetchType.LAZY ,orphanRemoval=true)
private List<News> news = new ArrayList<News>();
}
OK, chỉ cần như vậy và khi các bạn chạy lại, lỗi được giải quyết.
Trên là cách khắc phục lỗi A collection with cascade=”all-delete-orphan” was no longer referenced by the owning entity instance trong hibernate. Chúc các bạn khắc phục thành công!
Happy coding!
