我正在尝试对我的存储库进行测试，但在启动时会抛出此类异常，说实话，我现在不关心测试，这是编译错误，即使我尝试运行独立的 Spring Boot 应用程序代码也不会运行。 :

这是为什么呢？ 一切都运行良好，直到我开始迁移到反应性存储库。我认为 ReactiveCrudRepository 被注释为 @Component 但我不知道为什么它会下降。我的其他微服务使用完全相同的方法并且测试正在通过..
我的代码如下所示：
Repository:
public interface RecommendationRepository extends ReactiveCrudRepository<RecommendationEntity, String> {
Flux<RecommendationEntity> findByMovieId(int movieId);
}
测试：
@ExtendWith(SpringExtension.class)
@DataMongoTest
public class RecommendationRepositoryTest {
public static final int BASE_RECOMMENDATION_ID = 1;
public static final int BASE_MOVIE_ID = 2;
@Autowired
RecommendationRepository recommendationRepository;
RecommendationEntity savedRecommendationEntity;
@Test
void create() {
recommendationRepository.deleteAll();
RecommendationEntity given = RecommendationEntity.builder()
.recommendationId(BASE_RECOMMENDATION_ID)
.movieId(BASE_MOVIE_ID)
.content("Fake recommendation")
.build();
StepVerifier.create(recommendationRepository.save(given))
.expectNextMatches(recommendationEntity -> assertRecommendation(given, recommendationEntity))
.verifyComplete();
}
}
整个堆栈跟踪都指向该服务：为什么？
@Slf4j
@RestController
public class BaseRecommendationService implements RecommendationService {
private final ServiceUtil serviceUtil;
private final RecommendationRepository recommendationRepository;
private final RecommendationMapper mapper = RecommendationMapper.INSTANCE;
@Autowired
public BaseRecommendationService(ServiceUtil serviceUtil, RecommendationRepository recommendationRepository) {
this.serviceUtil = serviceUtil;
this.recommendationRepository = recommendationRepository;
}
@Override
public List<Recommendation> getRecommendations(int movieId) {
if (movieId < 1) throw new InvalidInputException("Invalid movieId: " + movieId);
// List<RecommendationEntity> recommendationEntities = recommendationRepository.findByMovieId(movieId).;
List<RecommendationEntity> recommendationEntities = new ArrayList<>();
List<Recommendation> recommendations = mapper.entityListToApiList(recommendationEntities);
recommendations.forEach(recommendation -> recommendation.setServiceAddress(serviceUtil.getServiceAddress()));
log.debug("Recommendation response size: {}", recommendations.size());
return recommendations;
}
@Override
public Recommendation createRecommendation(Recommendation recommendation) {
log.debug("createRecommendation: Trying to create recommendation entity: {}/{}", recommendation.getMovieId(), recommendation.getRecommendationId());
try {
RecommendationEntity recommendationEntity = mapper.apiToEntity(recommendation);
RecommendationEntity saved = recommendationRepository.save(recommendationEntity).block();
log.debug("createRecommendation: created a recommendation entity: {}/{}", recommendation.getMovieId(), recommendation.getRecommendationId());
return mapper.entityToApi(saved);
}catch (DuplicateKeyException e) {
throw new DuplicateKeyException("Non unique id for recommendation " + recommendation.getRecommendationId());
}
}
@Override
public void deleteRecommendations(int movieId) {
log.debug("deleteRecommendations: Trying to delete recommendation entity for movie " + movieId);
if (movieId < 1) throw new InvalidInputException("Invalid movieId: " + movieId);
recommendationRepository.deleteAll(recommendationRepository.findByMovieId(movieId));
}
}
更主要的类是这样的：
@Slf4j

public static void main(String[] args) {
ConfigurableApplicationContext context = SpringApplication.run(RecommendationServiceApplication.class, args);

看起来您错过了RecommendationRepository接口中的注释@Repository。 另外，正如我所看到的，您将 ReactiveCrudRepository 用于阻塞 MVC 应用程序，至少您可以面临性能问题，并且您的删除方法将不起作用，因为您必须订阅。您可以在官方文档中阅读更多内容。
尝试将 @ComponentScan(basePackages = {"com.xx.xx"}) 扫描添加到报告错误的模块的条目 xxxApplication 类中。我猜这个错误是因为没有扫描其他模块中的类或接口造成的。
