Here is the DAO class with problem:

import java.util.List;

import org.apache.cxf.service.invoker.SessionFactory;
import org.hibernate.Session;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import com.mahin.models.Users;

@Repository
public class usersDAO implements WebChatDAOs{

     @Autowired 
     private SessionFactory sessionFactory;

     private Session getCurrentSession() {
            return sessionFactory.getCurrentSession();
        }

    @Override
    public void addUser(Users user) {
        getCurrentSession().save(user);
    }

    @Override
    public void updateUser(Users user) {
        // TODO Auto-generated method stub

    }

    @Override
    public Users getUser(int id) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public void deleteUser(int id) {
        // TODO Auto-generated method stub

    }

    @Override
    public List<Users> getUsers() {
        // TODO Auto-generated method stub
        return null;
    }


}

Can anyone tell what is the problem?

Answer 1

Looks like you import the wrong SessionFactory. Use:

import org.hibernate.SessionFactory;

instead of:

import org.apache.cxf.service.invoker.SessionFactory;
