OneToOne Relationship with 2 fields of the same class
Greetings to all
I need make something live this
<entity OrdemServico>
@Table(name = "rkos20")
public class OrdemServico
{
// atributos
private String tipoRepasse;
private long codigoOS;
private OrdemServico oSOriginal;
private OrdemServico oSPai;
private Servico servico;
private Usuario requisitante;
private Usuario solicitante;
private String prioridade;
private Date dataAbertura;
private Date dataFechamento;
private String descProblema;
private boolean estaAtrasado;
private Usuario responsavel;
private String status;
private boolean fechamentoAutmat;
private CentroCusto cCustoEmissor;
private Area areaReceptora;
private String descAtendimento;
private Collection<Tarefa> tarefas;
private int horasTrab;
@Id(generate = GeneratorType.SEQUENCE , generator="COD_OS_GEN")
@Column(updatable = true, name = "num_os", nullable = false)
public long getNumero()
{
return codigoOS;
}
<still in OrdemServico>
@OneToOne(cascade = CascadeType.PERSIST)
@JoinColumn(name="num_os_pai")
public OrdemServico getOrdemServicoPai()
{
return oSPai;
}
@OneToOne(cascade = CascadeType.PERSIST)
@JoinColumn(name="num_os_orig")
public OrdemServico getOrdemServicoOriginal()
{
return oSOriginal;
}
the fields "num_os_pai" and "num_os_orig" are reffering other ids of OrdemServico.
When i try to load an OrdemServico i got the following :
SQL Error: 0, SQLState: 42703 09:38:38,179 ERROR [JDBCExceptionReporter] ERROR: column ordemservi0_.num_os_pai does not exist 09:38:38,180 INFO [DefaultLoadEventListener] Error performing load command
