example of a chunk of a controller class:
@Transactional
@Controller
public class PessoaController extends HttpServlet{
@Autowired
PessoaDaoI daopessoa;
@RequestMapping(value = "/listapessoas", method = RequestMethod.GET)
public String lista(Model model) {
//PessoaDao dao = new PessoaDao();
model.addAttribute("pessoas", daopessoa.lista());
//model.addAttribute("pessoas", dao.listaPessoas());
return "listapessoas";
