How to fix the Autowired dependencies failing in spring-mvc Hibernate - spring

Question

Hello (i am a new Spring MVC Hibernate developper) and i am working on a user regestration application in Spring MVC and Hibernate using Netbeans. I have a problem and i can not resolve it; it's #Autowired and beans problem.
This my Entity, User:
#Entity
#Table(name = "user")
public class User implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
/* attributes */
#Column(name = "Username")
private String userName;
#Column(name = "Email")
private String email;
#Column(name = "Firstname")
private String firstName;
#Column(name = "LastName")
private String lastName;
#Column(name = "BirthDate")
private String birthDate;
#Column(name = "PhoneNumber")
private String phoneNumber;
#Column(name = "PWHash")
private String pwHash;
}
The DAO interface
package com.Etravals.DAO;
import com.Etravels.Model.User;
public interface UserDAO {
public void addUser(User user);
}
DAO Impl:
import com.Etravels.Model.User;
import javax.transaction.Transactional;
import org.hibernate.SessionFactory;
import org.hibernate.Session;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
#Repository
#Transactional
public class UserDAOImpl implements UserDAO{
#Autowired
private SessionFactory sessionFactory;
private Session getSession(){
return sessionFactory.getCurrentSession();
}
#Override
public void addUser(User user) {
Session session = getSession();
session.save(user);
}
}
and service inteface :
package com.Etravels.Service;
import com.Etravels.Model.User;
public interface UserService {
public void addUser(User user);
}
Service Impl :
package com.Etravels.Service;
import com.Etravals.DAO.UserDAO;
import com.Etravels.Model.User;
import javax.transaction.Transactional;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
#Service
#Transactional
public class UserServiceImpl implements UserService{
#Autowired
private UserDAO userdao;
#Override
public void addUser(User user) {
userdao.addUser(user);
}
}
My HomeController :
#Controller
public class HomeController {
#Autowired
private UserService userService;
#RequestMapping(value="/")
public String showIndex(){
return "acceuil";
}
#RequestMapping(value="/addUser", method = RequestMethod.POST)
public ModelAndView addUser(#ModelAttribute("userFormSignUp") User user){
userService.addUser(user);
return new ModelAndView("redirect:/");
}
}
and this is my dispatcher-servlet.xml file :
<context:component-scan base-package="com.Etravels" />
<!-- Getting Database properties -->
<context:property-placeholder location="classpath:application.properties" />
<mvc:resources mapping="/resources/**" location="/resources/"/>

This is what I have as an error from Apache Tomcat server log :

Answer 1

Try
#Autowired(required=true)
private SessionFactory sessionFactory;
In UserDAOImpl class.
