我在Spring Boot中有一个关于存储库的问题。我有服务：

@Service("userService")
public class UserServiceImpl implements UserService {

  @Autowired
  private UserRepository userRepository;

  @Autowired
  private RoleRepository roleRepository;
}

和这里的回购：

@Repository("userRepository")
public interface UserRepository extends CrudRepository<User, Long> {
     User findByEmail(String email);
}

当我运行该应用程序时，我收到以下消息：

Description:

Field userRepository in com.projectWS.service.UserServiceImpl required a 
bean of type 'com.projectWS.repo.UserRepository' that could not be found.

Action:

Consider defining a bean of type 'com.projectWS.repo.UserRepository' in your 
configuration.

请帮助我，我很拼命…这是我的主要课程：

@SpringBootApplication
@Configuration
@EnableWebMvc
public class Main {

   public static void main(String[] args) {
    SpringApplication.run(Main.class, args);
   }
}

另一个问题是，@EnableJpaRepositories没有得到认可！
