Bem, estou quebrando a cabeça com o Hibernate.
estou tentando fazer de um jeito que quando a janela for aberta ele já preencha a tabela com os dados já existentes no banco.
mas… bem, vejam os códigos.
Onde deveria preencher:
[code]private void formWindowOpened(java.awt.event.WindowEvent evt) {
jTextFieldId.setFocusable(false);
jTextFieldId.setEditable(false);
jTextFieldClienteNovo.setVisible(false);
jTextFieldResponsavelNovo.setVisible(false);
//Tabela Preenchida
OrdemServicoDao<OrdemServico> osDao = new HibernateOrdemServicoDao();
ResponsavelDao<Responsavel> respDao = new HibernateResponsavelDao();
OrdemServico os = new OrdemServico();
//Responsavel resp = new Responsavel();
for(Integer i = 0; i < osDao.listar().size(); i++) {
for (Integer z = 0; z <respDao.listar().size(); z++) {
os.setId(osDao.listar().get(i).getId());
os.setResponsavel(osDao.listar().get(i).getResponsavel());
//os.setResponsavel(respDao.listar().get(z));
os.setCliente(osDao.listar().get(i).getCliente());
os.setTeamViewerId(osDao.listar().get(i).getTeamViewerId());
os.setAmmy(osDao.listar().get(i).getAmmy());
os.setDescricao(osDao.listar().get(i).getDescricao());
os.setData(osDao.listar().get(i).getData());
os.setHora(osDao.listar().get(i).getHora());
for(Integer x = 1; x < osDao.listar().size(); x++) {
for (Integer y = 1; y <osDao.listar().size(); y++) {
jTableOrdemServico.setValueAt(os.getId(), x, y);
}
}
}
}
}[/code]
Onde está o método está:
[code]package br.gs.dao;
import java.lang.reflect.ParameterizedType;
import java.util.List;
public class HibernateGenericDao implements DaoGenerico {
@Override
public T inserir(T t) {
HibernateUtil.getSessao().save(t);
return t;
}
@Override
public T alterar(T t) {
HibernateUtil.getSessao().update(t);
return t;
}
@Override
public T excluir(T t) {
HibernateUtil.getSessao().delete(t);
return t;
}
@SuppressWarnings("unchecked")
@Override
public List<T> listar() {
return HibernateUtil.getSessao().createCriteria(getClassEntidade()).list();
}
@SuppressWarnings("unchecked")
protected Class<T> getClassEntidade() {
return (Class<T>) ((ParameterizedType) getClass().getGenericSuperclass()).getActualTypeArguments()[0];
}
}
