JPA/hibernate sorted collection @OrderBy vs @Sort

Question

I would like to have a collection of child objects (here cat-kitten example) that are ordered. And keep their order on adding of new elements.

@Entity 
publ         


        

Answer 1

@Entity 
public class Cat {
  @OneToMany(mappedBy = "cat", cascade = CascadeType.ALL)
  private Set kittens = new TreeSet<>();
}

No need to write

@OrderBy("name ASC")

Make Sure Kitten Class implements Comparable interface properly.
