Olá,
estou com duvida qual exception usar quando o banco não está inicializado …
public class DAOFactory {
public static InstitutoDAO criarInstitutoDAO(){
InstitutoDAOHibernate institutoDAO = new InstitutoDAOHibernate();
institutoDAO.setSession(HibernateUtil.getSessionfactory().getCurrentSession());
return institutoDAO;
}
public class InstitutoRN {
private InstitutoDAO institutoDAO;
public InstitutoRN() {
this.institutoDAO = DAOFactory.criarInstitutoDAO();
}
public Object[] buscar() {
return this.institutoDAO.buscar();
}
public Long[] getCountAluno() {
return this.institutoDAO.getCountAluno();
}
}
