Ola, boa tarde.. preciso muito urgente desenvolver um simples crud com hibernate/JSP..
Mas estou com muita difciculdade em chamar os metodos da classe DAO pro formulario.. por enquanto so quero inserir dados no banco
Meu codigo:
CLIENTEDAOpackage persistencia.com;
import java.util.List;
import modelo.com.Cliente;
import org.hibernate.*;
import org.hibernate.cfg.AnnotationConfiguration;
public class ClienteDAO {
private static SessionFactory factory;
private static AnnotationConfiguration cfg;
private static Session getSession() {
return factory.openSession();
}
static {
cfg = new AnnotationConfiguration();
cfg.configure();
factory = cfg.buildSessionFactory();
}
public static void inserir(Cliente c) {
getSession().beginTransaction();
getSession().save(c);
getSession().getTransaction().commit();
getSession().close();
}
public static void deletar(Cliente c) {
getSession().beginTransaction();
getSession().delete(c);
getSession().getTransaction().commit();
getSession().close();
}
public static void atualizar(Cliente c) {
getSession().beginTransaction();
getSession().update(c);
getSession().getTransaction().commit();
getSession().close();
}
public static List listar(String estac) {
Query query = getSession().createQuery("from "+estac);
return query.list();
}
}
<%@page import="modelo.com.Cliente, persistencia.com.ClienteDAO" %>
<%
try{
String action = request.getParameter("action");
if(action.equalsIgnoreCase("inserir")){
Cliente c = new Cliente();
c.setCpf(request.getParameter("cpf"));
c.setNome(request.getParameter("nome"));
c.setPlaca(request.getParameter("placa"));
c.setModelo(request.getParameter("modelo"));
c.setCor(request.getParameter("cor"));
ClienteDAO cd = new ClienteDAO();
try{
cd.inserir(c);
request.setAttribute("msg", "Cadastrado com sucesso!");
request.getRequestDispatcher("index.jsp").forward(request, response);
}catch(Exception e){
out.print("Erro:"+e.getMessage());
}
}
}catch(NullPointerException nexp){
out.print("Você deveria estar vendo este aviso");
}
