如何修复JAVA spring boot中的“​​考虑定义类型的bean”错误？

Question

我正在为我的应用程序使用spring boot和spring数据mongodb。我有一个扩展MongoRepository的接口，例如：

public interface CardsRepository extends MongoRepository<Card, String>

我在服务类中使用该存储库，如下所示：

private CardsRepository cardsRepository;

  @Autowired
  public CardsServiceImpl(CardsRepository cardsRepository) {
    this.cardsRepository = cardsRepository;
  }

但是当我运行代码时，出现以下错误：

Description:

Parameter 0 of constructor in *.*.*.service.CardsServiceImpl required a bean of type '*.*.*.repository.CardsRepository' that could not be found.


Action:

Consider defining a bean of type '*.*.*.repository.CardsRepository' in your configuration.

I have tried annotating my Repository interface with @Repository but to no success.
