我在春季测试中有这种行为,但我没有看到它在运行应用程序。
即使@SpringBootTest(classes = {OpenElevationClient.class})
注释中提到了OpenElevationClient
接口,我的测试类也无法加载OpenElevationClientImpl
bean。
这篇文章的目的是,如果我在@SpringBootTest
注释中引用了来自OpenElevationClient
接口的同一个包的具有@ComponentScan
注释的类,那么我无法解释OpenElevationClientImpl
bean是否正确加载。
测试类
@ExtendWith(SpringExtension.class)
@SpringBootTest(classes = {RestClientConfig.class, OpenElevationConfig.class})
public class EnrichmentUtilsTest {
@Autowired
ApplicationContext applicationContext;
@Autowired
OpenElevationClient elevationClient;
@Test
public void printBeans() {
for(String tmp:Arrays.asList(applicationContext.getBeanDefinitionNames())){
System.out.println(tmp);
}
}
}
以下所有类都来自同一个包。
OpenElevationClient接口:如果该类在@SpringbootTest
中,则未找到bean
@ComponentScan
public interface OpenElevationClient {
LocationElevationResultsDTO getElevation(String locations);
}
OpenElevationConfig类:如果该类在@SpringbootTest
中,则找到bean
@ComponentScan
public class OpenElevationConfig {
}
OpenElevationClientImpl bean
@Service
public class OpenElevationClientImpl implements OpenElevationClient {
private OpenElevationLookupApi openElevationLookupApi;
@Autowired
public OpenElevationClientImpl(OpenElevationLookupApi openElevationLookupApi, @Value("${openelevation.api.url}") String basePath) {
openElevationLookupApi.getApiClient().setBasePath(basePath);
this.openElevationLookupApi = openElevationLookupApi;
}
@Override
public LocationElevationResultsDTO getElevation(String locations) {
return this.openElevationLookupApi.getLookup(locations);
}
}
同样,这种行为仅在运行测试时可见,OpenElevationConfig.class
仅用作组件类,用于在测试类中加载ApplicationContext。我错过了什么可以向我解释这种奇怪行为的东西?
编辑16/12/2021-回购以复制https://github.com/charlycou/stackoverflow-70198445.
- 在测试(AppTest(中将OpenElevationConfig.class替换为OpenElevation Client.class,测试将失败
- 删除OpenElevationConfig.class并运行Main.class,应用程序运行良好
对于原始问题:
在参考文档中,我只在@Configuration
类上看到@ComponentScan
。
但我能从你的(git(回购中得到的是:

Results:

这个测试:
