Hibernate annotated UUID

If you want to identify portably an object, it can be interesting to store this one with an UUID as an ID.
No boring 1, 2, 3,… as primary key 🙂

@Entity
public class Context implements Serializable {
   @Id
   @GeneratedValue(generator = "system-uuid")
   @GenericGenerator(name = "system-uuid", strategy = "uuid")
   private String id;
...
}
