[RESOLVIDO]Problemas com Spring MVC 3.2 e Hibernate 3

Front-end
#1

Galera, boa tarde estou estudando Java Web e estou encontrando algumas dificuldades ao tentar realizar a injeção de dependência com o Spring.
estou tentando fazer um login e estou recebendo o seguinte erro.

O loco, pra que isso tudo de código mano? fica até dificil de olhar se teu erro não fosse fácil. O.o

A mensagem de erro fala que o erro está aqui:
at br.com.sge.logica.UsuarioLogica.efetuarLogin(UsuarioLogica.java:23)
user = usuarioDAO.procuraLoginSenha(u.getLogin_usuario(), u.getSenha_usuario());

Vocẽ viu quem está null aí?

#3

pois é cara tava tentando depurar pelo netbeans mais não passa dessa linha

user = usuarioDAO.procuraLoginSenha(u.getLogin_usuario(), u.getSenha_usuario());

usuarioDAO é null

sei que ele não ta sendo inicializado pelo Spring, mas ainda consegui fazer isso acontecer.

foi malae a quantidade de codigo coloquei tudo, pensei que quanto mais informação mas fácil seria pra responder :oops:

    Seu problema esta na classe acima, porque você não transformou o UsuarioLogica em um bean gerenciado pelo Spring. Assim, ele não consegue injetar o DAO. Adicione a anotação @Service do Spring, acima do nome da classe.

E você não precisa usar:

&lt;bean id="usuarioDAO" class="br.com.sge.dao.implementacao.UsuarioDAO"&gt; &lt;property name="sessionFactory" ref="sessionFactory"/&gt; &lt;/bean&gt;
Você já ta fazendo isso na classe UsuarioDAO através das anotações @Repository e @Autowired.

Troque a anotação @Resource(name=“usuarioDAO”) de UsuarioLogica por @Autowired, mantenha um padrão entre as anotações dentro do projeto.

#5

cara fiz o que você falou mas o erro continua do mesmo jeito

Na classe LoginController faça assim:

/*

 */
package br.com.sge.controller;

import br.com.sge.logica.UsuarioLogica;
import br.com.sge.modelo.Usuario;
import javax.servlet.http.HttpSession;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

/**

 */
@Controller
public class LoginController {

    private UsuarioLogica usuarioLogica; //adicione

    @Autorwired // adicione tudo isso
    public LoginController(UsuarioLogica usuarioLogica) {
        this.usuarioLogica = usuarioLogica;
    }

    @RequestMapping("loginForm")
    public String loginForm() {
        return "formulario-login";
    }

    @RequestMapping("efetuarLogin")
    public String efetuarLogin(Usuario usuario, HttpSession session) {

        if (usuario != null) {

            Usuario user;


            user = usuarioLogica.efetuarLogin(usuario); // altere aqui

            if (user != null) {
                session.setAttribute("usuarioLogado", user);
                return "menu";
            } else {
                return "redirect:loginForm";
            }

        } else {
            return "redirect:loginForm";
        }
    }

    @RequestMapping("logout")
    public String efetuarLogout(HttpSession session) {
        session.invalidate();
        return "redirect:loginForm";
    }
}
