3-create the service and service Imp : 3-创建服务和服务Imp：
public interface UserService {
public User findOne(Long id);

@Service
public class UserServiceImpl implements UserService {
@Resource
UserDao userRepository;
@Override
public User findOne(Long id) {
User user = userRepository.findOne(id);
return user;
}
