@Entity(name = "user")
@Table(name = "user")
public class User {

    @Id
    @Column(name = "id")
    private String id;  
    @Column(name = "password")

//getter and setter for this..
}

@Repository
@Transactional
public class UserImpl implements UserDAO {

    private DataSource dataSource;

    @Autowired
    SessionFactory sessionFactory;
    @Resource(name = "sessionFactory")
    public void setDataSource(DataSource dataSource) {
        this.dataSource = dataSource;
    }

    @Override
    public String insert(User use) {

        Session session = this.sessionFactory.openSession();
        try{

            Session sess = this.sessionFactory.getCurrentSession();              
            session.save(reg);


                        return (String)user.getUserName(); 
                        }catch(Exception e){
                            System.out.println("in catch"+e.getMessage());
                            e.printStackTrace();
