Я использую Spring Boot 2.1.6 и намереваюсь писать интеграционные тесты, используя самописный сервис, помеченный @Service.
Тесты работают хорошо, пока я не попытаюсь выполнить автоматическое подключение службы, упомянутой выше, и она жалуется:
Unsatisfied dependency expressed through field 'myService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'de.xxx.MyService' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
Мой тестовый класс помечается следующим образом:
@ExtendWith(SpringExtension.class)
@SpringBootTest (properties = "spring.main.allow-bean-definition-overriding=true",
classes = {MyConfig.class, RestTemplateAutoConfiguration.class, MyService.class})
@WebAppConfiguration
@TestPropertySource("classpath:application.properties")
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
ВВ этот момент возникает ошибка:
@Autowired
private MyService myService;
Что я могу сделать?
Я предположил, что в тестах известен контекст приложения реального приложения (например, бины / компоненты / службы /). ..). Разве это не так?
Интерфейс службы:
package de.xyz.xxx;
public interface MyService {
void doXyz();
}
Реализация службы:
@Service("myService")
public class MyServiceImpl implements MyService {
private static final Logger log = LoggerFactory.getLogger(MyServiceImpl.class);
private final String MY_API_KEY;
public MyServiceImpl(final @Value("${xxx.yyy.key}") String apiKey) {
MY_API_KEY = apiKey;
}
}
У меня не было ни успеха ни при использовании @ComponentScan("de.xyz.xxx"), ни при использовании @SpringBootTest(classes = {MyServiceApplication.class})
Я понял, что аннотировал реализацию службы с помощью @Service, но использовал MyService.class с @SpringBootTest. Однако, когда я пытаюсь импортировать весь контекст, используя MyApplication.class с @SpringBootTest (с MyServiceImpl.class или без него), я получаю это исключение только потому, что я определил bean-компонент в классе конфигурации теста. И снова: не имеет значения, если я аннотирую класс конфигурации с помощью @Configuration или @TestConfiguration:
Test ignored.

Так что же это такое org.springframework.hateoas.config.ConverterRegisteringWebMvcConfigurer и как я могу решить эту проблему?
