... 42 moreAnalisei meu POJO e esta tudo correto, segue o código:
@Entity
@Table(name="tbl_operadora")
public class Operadora implements PersistentEntity<Integer>{
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name="id_operadora", nullable=false)
private Integer idEntity;
public Operadora() {}
@Override
public Integer getIdEntity() {
return idEntity;
}
@Override
public void setIdEntity(Integer idEntity) {
this.idEntity = idEntity;
}
}O meu controller herda de uma classe genérica onde tenho um método genérico de listagem, segue o codigo:
@Post
@Override
public void list(T obj, Pagination pagination)
throws WiseException
{
PersistenceFilter filter = this.listFilter(obj);
if(pagination.getOrder() != null)
{
filter.setOrdernacao(pagination.getOrder(), pagination.getOrderField());
}
pagination.setAllRecords(this.genericRepository.count(filter));
pagination.setRows(this.genericRepository.list(filter, pagination.getInicio(ALL_RECORDS_BY_PAGE), pagination.getAllRecordsByPage()));
this.result.use(Results.json()).withoutRoot().from(pagination).include("rows").serialize();
}Alguém já passou por problema parecido ?
