注释 @ConditionalOnMissingBean 在测试中不匹配 [英] Annotation @ConditionalOnMissingBean not matching in test

问题描述

我有一个接口的两个实现 - default 和 dev.我使用 @ConditionalOnProperty 作为默认实现和 @Profile 和 @ConditionalOnMissingBean 的组合用于开发实现.

I have two implementations of one interface - default and dev. I use @ConditionalOnProperty for default implementation and combination of @Profile and @ConditionalOnMissingBean for dev implementation.

@Service
@ConditionalOnProperty(prefix = "keystore", value = "file")
public class DefaultKeyStoreService implements KeyStoreService {

@Service
@Profile("dev")
@ConditionalOnMissingBean(KeyStoreService.class)
public class DevKeyStoreService implements KeyStoreService {

现在，问题出在 DevKeyStoreService 的测试 DevKeyStoreServiceTest 中.我有这样的配置:

Now, the problem is in test DevKeyStoreServiceTest for DevKeyStoreService. I have configuration like this:

@SpringBootTest(
    classes = {DevKeyStoreService.class},
    properties = {"keystore.file="}
)
@RunWith(SpringRunner.class)
@ActiveProfiles("dev")
public class DevKeyStoreServiceTest {

    @Autowired
    private DevKeyStoreService tested;

    @Test
    public void testPrivateKey() {
    } //... etc.

结果是:

Negative matches:
-----------------
DevKeyStoreService:
   Did not match:
      - @ConditionalOnMissingBean (types: service.crypto.KeyStoreService; SearchStrategy: all) found bean 'devKeyStoreService' (OnBeanCondition)

和典型的org.springframework.beans.factory.UnsatisfiedDependencyException:创建名为service.crypto.DevKeyStoreServiceTest"的bean时出错....

如何配置测试类才能运行它?

How can I configure the test class to be able to run it?

推荐答案

好的，我想通了.

带有值的注释 @ConditionalOnMissingBean(KeyStoreService.class) 试图只找到具体的实例，而 KeyStoreService 接口不是.这样，它找不到任何东西.

Annotation with value @ConditionalOnMissingBean(KeyStoreService.class) tries to find only concrete instances, which interface KeyStoreService is not. This way, it doesn't find anything.

当我使用带有类型的注释时，它的作用就像一个魅力:@ConditionalOnMissingBean(type = "KeyStoreService").

When I use annotation with type instead, it works like a charm: @ConditionalOnMissingBean(type = "KeyStoreService").
