I defined a entity with a uuid primary key:
@Entity
@Table(name = "SITES")
public class Site extends Model {
@Id
@Column(length = 32)
@GeneratedValue(generator = "system-uuid")
@GenericGenerator(name = "system-uuid", strategy = "uuid")
private String id;
}
It works fine, but I found hibernate will always override the specified id:
When I save a Site object with specified uuid 402881e533fe2de70133fe2df6790000, like:
Site site = new Site();
site.setId("402881e533fe2de70133fe2df6790000");
siteDao.save(site);
Print the id:
System.out.println(site.id);
Get:
402881e534110dc30134110dd4e80000
Is there any way to ask hibernate don't override my specified uuid?
Why you want to use setId(). You should let Hibernate handle the ids and everything is right.
Hibernate sets the id if you persist a new Object.
I don't think this is an acceptable response. The OP made the point clear. Why replying with a different question?
You are right. The Answer to the specific question is: Don't use a @GeneratedValue and Hibernate won't override your default ID.
