bean tidak melakukan autowiring dalam integrasi hibernasi dan pegas mvc?

Saya baru mengenal spring dan membuat halaman login menggunakan spring dan hibernate tetapi pada saat mendapatkan sessionFactory saya mendapat kesalahan ini -

Musim Semi: Tidak ada Sesi Hibernasi yang terikat ke thread, dan konfigurasi tidak mengizinkan pembuatan sesi non-transaksional di sini

Saya berjuang dari 1 hari. Bagaimana saya bisa mengatasinya. Kode saya adalah -

Dao Pengguna -

package com.mogae.springLogin.db.dao;

import java.util.ArrayList;
import java.util.List;
import java.util.logging.Logger;

import org.hibernate.SessionFactory;

import com.mogae.springLogin.entities.User;

public class UserDao {

    private static Logger LOGGER = Logger.getLogger(UserDao.class.getName());
    private SessionFactory sessionFactory;



    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

    @SuppressWarnings("unchecked")
    public User findUser(String username,String password)
    {
        List<User> users = new ArrayList<User>();
        try{
    //      LOGGER.info("session = "+getFactory().getCurrentSession().isOpen());
        LOGGER.info("login for username = "+username);
        users = getSessionFactory().getCurrentSession().createQuery("from user_data where username =? and password = ?").setParameter(0, username).setParameter(1, password).list();
        }catch(Exception e){
            e.printStackTrace();
        }

        if(users.size()>0)
            return users.get(0);
        else
            return null;
    }

}

Kelas pengontrol adalah -

package com.mogae.springLogin.controllers;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;

import com.mogae.springLogin.db.dao.UserDao;
import com.mogae.springLogin.entities.User;

@Controller
@RequestMapping("/login")
public class LoginController {

@Autowired
private UserDao userDao;


    @RequestMapping(method = RequestMethod.POST)
    public ModelAndView loginUser(@RequestParam("username") String username,
            @RequestParam("password") String password) {
        User user = userDao.findUser(username, password);
        if (user != null)
            return new ModelAndView("jsp/result", "message",
                    "successfully login with user = " + username);
        else
            return new ModelAndView("jsp/index", "message",
                    "invalid login");
    }

Apa yang bukan metode penyetel yang valid? Anda perlu memberi saya sesuatu yang nyata, bukan interpretasi Anda terhadapnya. Bisakah Anda memposting jejak tumpukan?   -  person ConMan    schedule 18.01.2015

@ConMan Saya telah menambahkan jejak tumpukan yang dimaksud... periksa juga untuk properti ini dikatakan bahwa untuk ini tidak ditemukan penyetel yang valid - ‹property name=current_session_context_class›org.hibernate.context.ThreadLocalSessionCon‌​text‹/property›   -  person Amit Das    schedule 18.01.2015

Anda memerlukan transaksi untuk menggunakan Hibernate. Baca dokumentasi tentang transaksi di dokumentasi Spring: docs .spring.io/spring/docs/current/spring-framework-reference/   -  person JB Nizet    schedule 18.01.2015

saya pikir Anda perlu melakukan autowire ini: private SessionFactory sessionFactory; di UserDao   -  person Abhi    schedule 18.01.2015

Sejauh yang saya tahu Spring mencari antarmuka ke kacang Autowired, jadi saya pikir Anda harus mendeklarasikan antarmuka untuk kelas Anda userDao, dan dalam implementasinya Anda meletakkan anotasi @Repository("userDao") seperti ini

public interface UserDao {
   .......
}

@Repository("userDao")
public class UserDaoImpl implements UserDao {
 ........
}

tapi saya menginginkannya tanpa menggunakan antarmuka apa pun. - person Amit Das; 18.01.2015
