Hibernate: How to use cascade in annotation?
How can I use cascade and annotations in hibernate?
But I stay with a 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 to session.save(package)
, an error occurs.
I don't want to save product and package. I just want to initialize and set them into my package object.
Is that possible?
Solution 1:
See the hibernate documentation which is very clear on this issue. For instance you could use e.g.,
@Cascade(CascadeType.PERSIST)
private List<Object> obj;
or
@OneToMany(cascade = CascadeType.PERSIST)
private List<Object> obj;
Solution 2:
If you use the hibernate native API , then you should use the annotation of hibernate for cascade and it is :
@Cascade(CascadeType.SAVED_UPDATE)
then you call save() method but with your annotation , you should call the method persist() of the JPA
