Java – Hibernate: how to use cascading in annotations?

How to use cascading and annotation in Hibernate?

But I doubt:

I have this situation:

public class Package(){
  @OneToOne(cascade=CascadeType.PERSIST)
  private Product product;

  @OneToOne(cascade=CascadeType.PERSIST)
  private User user;
  ..
}

When I try session An error occurs when saving a package I don't want to save products and packages, just initialize them and set them as my package objects

Is that possible?

Solution

The problem of Hibernate documentation is very clear For example, you can use,

@Cascade(CascadeType.PERSIST)
private List<Object> obj;

or

@OneToMany(cascade = CascadeType.PERSIST)
private List<Object> obj;
