Y ya he cambiado el tipo de dato:
public class Pedido {
private Integer codigo;
private Cliente cliente;
private String estado;
private Set <ProductoForm> listadodeproductos;
public void setCodigo(Integer codigo) {
this.codigo = codigo;
}
public Integer getCodigo() {
return codigo;
}
Base de datos:
- codigo bigint(20)
- codigo_cliente bigint(20)
- estado varchar(20)
mapeo:
<class name="local.model.Pedido" table="pedidos">
<id column="codigo" name="codigo">
<generator class="native"/>
</id>
<many-to-one name="cliente" column="codigo_cliente" class="local.model.Cliente" not-null="true"/>
<property column="estado" name="estado" />
<set name="listadodeproductos" table="detalle_pedidos" inverse="true" fetch="select">
<key>
<column name="codigo_pedido" not-null="true" />
</key>
<one-to-many class="local.model.ProductoForm" />
</set>
</class>
