Class UUIDGenerator

java.lang.Object
  org.hibernate.test.annotations.id.sequences.UUIDGenerator

All Implemented Interfaces:

IdentifierGenerator

public class UUIDGenerator
extends Object
implements IdentifierGenerator

Unlike Hibernate's UUID generator. This avoids meaningless synchronization and has less than a chance of an asteroid hitting you on the head even after trillions of rows are inserted. I know this to be true because it says so in Wikipedia(haha). http://en.wikipedia.org/wiki/UUID#Random_UUID_probability_of_duplicates
