org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userServiceImpl'

I am integrating hibernate and spring and jsf.

I got this exception:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userServiceImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.sajjad.dao.UserDao com.sajjad.service.UserServiceImpl.userDao;

nested exception is org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [com.sajjad.dao.UserDao] is defined: expected single matching bean but found 2: orderDaoImpl,userDaoImpl.

Here is userServiceImpl:

@Service
public class UserServiceImpl implements UserService<User, Integer>, Serializable {

@Autowired
private UserDao userDao;
//other methods

And this is UserDaoImpl:

@Component
public class UserDaoImpl implements UserDao<User, Integer>, Serializable {

@Autowired
private SessionFactory sessionFactory;
// other methods

And here is applicationContext.xml:
