Hibernate Pedidos +ItensPedido

http://www.java2s.com/Code/Java/Hibernate/Relation-One-to-Many.htm

Que tal?

Faça pesquisas no Fórum, Google e Na documentação do Hibernate mesmo, encontrará exemplos funcionais!

Tente isso
:lol:

Eu procurei no Forum mas não sabia sobre o que procurar exatamente…

Mas vou tentar seguir as dicas dos colegas e volto a postar aqui…

A eu esqueci de falar eu to usando Hibernate Annotations

Obrigado pela atenção de vc’s

Fabiano, tente olhar na documentação de Anotation do Hibernate.
Deve ser algo do tipo: @cascade na tua lista de itens la no pedido…
De uma olhada qualquer coisa retorne

Vou colocar aqui como estou fazendo parece estar tudo certo... Parece né pois se estivese taria funcionando hauahu..

Muito obrigado pela ajuda e atenção de todos.

Classe Pedido

package beans;

// imports

@Entity
@Table(name="tbPedido", schema="public")
public class Pedido implements Serializable {

	@Id
	@SequenceGenerator(name="seqPed", sequenceName="seqPed", initialValue=1)
	@GeneratedValue(generator="seqPed", strategy=GenerationType.AUTO)
	private Integer pedCod;
	
	@ManyToOne
	@JoinColumn(name="cliCod", referencedColumnName="cliCod")
	private Cliente cliente;
	
	@Temporal(value=TemporalType.DATE)
	private Date pedData;
	
	@Temporal(value=TemporalType.DATE)	
	private Date pedDataEntrega;
	
	private BigDecimal pedTotal;
	
	private boolean pedGerado;
	
	@OneToMany(mappedBy="pedido", cascade=CascadeType.ALL, fetch=FetchType.LAZY)
	private List<ItemPedido> itensPedido;
	
	public Pedido() {
		// TODO Auto-generated constructor stub
	}
  
        //Getter's e Setter's

}

Classe ItemPedido

package beans;

//Imports

	private Pedido pedido;
	
	public ItemPedido() {
		
	}

        //Getter's e Setter's
}

ItemPedidoPk

package beans;

//Imports

@Embeddable
public class ItemPedidoPk implements Serializable {

	private static final long serialVersionUID = 1L;

	private Integer pedCod;
	
	private Integer proCod;
	
	public ItemPedidoPk() {
	}

       //Getter's e Setter's
}

Fazendo deste jeito qual problema que está ocorrendo?

Ele da esse erro aqui

E se eu mudar a tabela ItemPedido Para

package beans;

//Imports

@Entity

@Table(name=“tbItenPedido”, schema=“public”)

public class ItemPedido implements Serializable {

private static final long serialVersionUID = 1L;

//@EmbeddedId
//private ItemPedidoPk itemPedidoPk;
@Id
@SequenceGenerator(name="seqItPed", sequenceName="seqItPed", initialValue=1)
@GeneratedValue(generator="seqItPed", strategy=GenerationType.AUTO)	
private Integer itpedCod;

private Float itpedQtde;

private Float itpedPrecoVenda;

private Float itpedPrecoTotal;

@ManyToOne()
@JoinColumn(name="pro_Cod", referencedColumnName="proCod", insertable=true, updatable=true)
private Produto produto;

@ManyToOne(fetch=FetchType.EAGER)
@JoinColumn(name="ped_Cod", referencedColumnName="pedCod", insertable=true, updatable=true)
@Fetch(FetchMode.JOIN)
@Cascade(CascadeType.SAVE_UPDATE)
private Pedido pedido;

public ItemPedido() {
}

    //Getter's e Setter's

}

Funciona sertinho o que será que pode ser
