Eu dei uma olhada no Exemplo, e estou fazendo desse forma.
DAO
package negocio.entidade;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Lob;
import javax.persistence.NamedQueries;
import javax.persistence.NamedQuery;
import javax.persistence.Table;
@Entity
@Table(name = "anexo")
@NamedQueries({
@NamedQuery(name = "Anexo.findAll", query = "SELECT a FROM Anexo a"),
@NamedQuery(name = "Anexo.findByAnexoId", query = "SELECT a FROM Anexo a WHERE a.anexoId = :anexoId")})
public class Anexo implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@Column(name = "anexo_id", nullable = false)
private Integer anexoId;
@Lob
@Column(name = "anexo")
private byte[] anexo;
public Anexo() {
}
public Anexo(Integer anexoId) {
this.anexoId = anexoId;
}
public Integer getAnexoId() {
return anexoId;
}
public void setAnexoId(Integer anexoId) {
this.anexoId = anexoId;
}
public byte[] getAnexo() {
return anexo;
}
public void setAnexo(byte[] anexo) {
this.anexo = anexo;
}
@Override
public int hashCode() {
int hash = 0;
hash += (anexoId != null ? anexoId.hashCode() : 0);
return hash;
}
@Override
public boolean equals(Object object) {
// TODO: Warning - this method won't work in the case the id fields are not set
if (!(object instanceof Anexo)) {
return false;
}
Anexo other = (Anexo) object;
if ((this.anexoId == null && other.anexoId != null) || (this.anexoId != null && !this.anexoId.equals(other.anexoId))) {
return false;
}
return true;
}
@Override
public String toString() {
return "negocio.entidade.Anexo[ anexoId=" + anexoId + " ]";
}
}Ae que vem minha dúvida , quero jogar para minha tabela ou gravar em uma pasta.
Estou seguindo esse exemplo.
MB
