This tutorial describes how to map an Oracle Sequence with JPA.

 

Supposing that you have just created an Oracle sequence using the command:

CREATE SEQUENCE AGENDA_SEQ;

Then, you can use this sequence in your Entity as follows:

@Entity 
public class Agenda {
     

@Id
@GeneratedValue(strategy=GenerationType.AUTO, generator="my_entity_seq_gen")
@SequenceGenerator(name="my_entity_seq_gen", sequenceName="AGENDA_SEQ", allocationSize = 1)
private Long id;

}

The @SequenceGenerator annotation is used to define a sequence and accepts a name, an initial value (the default is 1) and an allocation size (the default is 50). A sequence is global to the application and can be used by one or more fields in one or more classes
