I have two classes documentlog and documentversion(with primary keys: int doc_id and int docVersionID) with a many-to-one relationship. I used a composite key class called CompundKey to manage the compound primary key. I need to auto increment docversionID but I am not able to do that. Could you please help me in this regard?
@Entity
@Table(name = "Documentversion", schema = "DocumentManagement")
public class DocumentVersion implements Serializable {
private CompoundKey id;
private List<DocumentLog> documentLog;
@OneToMany(mappedBy="documentVersion", targetEntity=DocumentLog.class,
cascade ={CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH})
public List<DocumentLog> getDocumentLog() {
return documentLog;
}
public void setDocumentLog(List<DocumentLog> documentLog) {
this.documentLog = documentLog;
}
@EmbeddedId
@AttributeOverride(name="doc_Id", column=@Column(name="doc_Id") )
public CompoundKey getId() {
return id;
}
public void setId(CompoundKey id) {
this.id = id;
}
}
