在集成测试期间使用嵌入式 mongo 连接 bean

Question

我正在将 spring-boot (2.2.7.RELEASE) 与 webflux 一起用于 mongodb 的小型休息服务。我有 2 个存储库（ARepository、BRepository）实现了如下内容：

@Repository
public interface ARepository extends ReactiveMongoRepository<DataDTO, Integer> {
}

我还有一个额外的服务，它使用这两个和一个 ReactiveMongoTemplate 实例。它是这样连接的：

@Slf4j
@Service
public class DefaultTheService implements TheService {
    private final ARepository aRepository;
    private final BRepository bRepository;
    private final ReactiveMongoTemplate mongoTemplate;

    @Autowired
    public DefaultTheService(ARepository aRepository, BRepository bRepository, ReactiveMongoTemplate mongoTemplate) {
        this.aRepository = aRepository;
        this.bRepository = bRepository;
        this.mongoTemplate = mongoTemplate;
    }
}

一切都很好，一切正常，没有问题。

现在，我想写一些集成测试，我是这样开始的：

@DataMongoTest
@Slf4j
class DefaultTheServiceTest {

    @Autowired
    private ARepository aRepository;

    @Autowired
    private BRepository bRepository;

    @Autowired
    private ReactiveMongoTemplate reactiveMongoTemplate;

    @Autowired
    private DefaultTheService defaultTheService;

    @Test
    void runTheMagicTest() {
        // empty body, I just want to see if everything wires up correctly.
    }
}

当我想执行runTheMagicTest（junit5）时，我总是得到这个错误：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.example.DefaultTheServiceTest': Unsatisfied dependency expressed through field 'defaultTheService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.example.DefaultTheService' available: expected at least 1 bean which qualifies as autowire candidate.

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.example.DefaultTheService' available: expected at least 1 bean which qualifies as autowire candidate.

    at org.springframework.beans.factory.support.DefaultListableBeanFactory.resolveDependency(DefaultListableBeanFactory.java:1226)

*！注意 bean 名称：DefaultTheServiceTest

通常，我可以在每次测试之前简单地创建一个 DefaultTheService 实例，然后调用我想要测试的方法，但我想尝试使用 spring。

如果我简单地删除 private DefaultTheService defaultTheService 声明 - 测试是“运行”。我很确定我错过了一些愚蠢的东西，我正在追尾。

那么，有人可以减轻我的痛苦并指出我正在犯的（可能吗？）明显的错误？

谢谢！

Answer 1

@DataMongoTest:

Annotation that can be used for a MongoDB test that focuses only on MongoDB components.

Using this annotation will disable full auto-configuration and instead apply only configuration relevant to MongoDB tests.

改为尝试 @SpringBootTest 以获得“完整”/默认应用程序上下文。

有关一般信息，请参阅：

https://docs.spring.io/spring-framework/docs/current/reference/html/testing.html#testing

对于（自动）配置详细信息和改进：

https://docs.spring.io/spring-boot/docs/current/reference/html/features.html#features.testing

...设置@DataMongoTest(useDefaultFilters = false)（+微调include-/excludeFilters）也可以达到预期效果。
