 Post subject: Hibernate - SequenceGenerator and EmbeddedId

Hello,

I am developing a system in an existing database and I have difficulty using a sequence of bank within a Hibernate Embeddable mapping.

Whenever I try to insert a new record value of idPessoa (PES_ID) is zero, it does not trigger the sequence.

Does anyone know how to solve this problem?

Class Main table:

Code:
@Entity 
@Table(name = "PES_PESSOA" ) 
public class Pessoa implements Serializable { 
 
private static final long serialVersionUID = 1L; 
 
@EmbeddedId   
private PessoaPK id; 
 
@Column(name = "PES_NOME" ) 
private String nome; 
 
@Column(name = "PES_LOGRADOURO" ) 
private String logradouro; 
 
@Column(name = "PES_BAIRRO" ) 
private String bairro;   
.... 



Class Embeddable with Sequence:

Code:
@Embeddable 
public class PessoaPK implements Serializable { 
 
private static final long serialVersionUID = 1L; 
 
@Column(name = "EMP_ID" ) 
private long idEmpresa; 
 
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "sequenciaPessoa" ) 
@SequenceGenerator(name = "sequenciaPessoa", sequenceName = "S_PES_PESSOA", allocationSize = 1 ) 
@Column(name = "PES_ID" ) 
private long idPessoa; 
... 
}


Grateful!

I don't think that is possible to have @GeneratedValue with @EmbeddedId. However, you could use a regular EmbeedId and assign the value manually by calling a database sequence.
