Annotation Interface UuidGenerator

@Target({TYPE,METHOD,FIELD})
@Retention(RUNTIME)
@Repeatable(UuidGenerators.class)
public @interface UuidGenerator

Defines a primary key generator that may be referenced by name when a generator element is specified for the GeneratedValue annotation.

A UUID generator may be specified on the entity class or on the primary key field or property.

The scope of the generator name is global to the persistence unit (across all generator types).

Example:

 @Entity
 public class Employee {
     ...
     @UuidGenerator(name="uuid")
     @Id
     @GeneratedValue(generator="uuid")
     int id;
     ...
 }
