【问题描述】:
我正在尝试运行我的应用程序并收到此错误:
***************************
APPLICATION FAILED TO START
***************************
Description:
Parameter 0 of constructor in com.danielturato.product.services.ProductServiceImpl required
a bean of type 'com.danielturato.product.persistence.ProductRepository' that could not be
found.
Action:
Consider defining a bean of type 'com.danielturato.product.persistence.ProductRepository' in
your configuration.
我不知道为什么会这样。我试图查看过去的解决方案,其中说使用 @EnableMongoRepository 指向正确的包,但是我已经尝试过,但它不起作用。我还尝试在我的存储库上方添加 @Repository 注释(即使它不需要),但它仍然无法正常工作。这是我的存储库、应用程序以及无法注入存储库的代码。
应用:
@SpringBootApplication
@ComponentScan("com.danielturato")
public class ProductServiceApplication {
private static final Logger LOG = LoggerFactory.getLogger(ProductServiceApplication.class);
public static void main(String[] args) {
SpringApplication.run(ProductServiceApplication.class, args);
}
}
存储库:
public interface ProductRepository extends ReactiveCrudRepository<ProductEntity, String> {
Mono<ProductEntity> findByProductId(int productId);
}
ProductServiceImpl:
@RestController
public class ProductServiceImpl implements ProductService {
private static final Logger LOG = LoggerFactory.getLogger(ProductServiceImpl.class);
private final ServiceUtil serviceUtil;
private final ProductRepository repository;
private final ProductMapper mapper;
@Autowired
public ProductServiceImpl(ProductRepository repository, ProductMapper mapper, ServiceUtil serviceUtil) {
this.repository = repository;
this.mapper = mapper;
this.serviceUtil = serviceUtil;
}
