Я пытаюсь выполнить миграцию Springboot 1.xy (Brussels-SR12) на 2.xy. Я использую FeignClients
Я изменяю конфигурацию Maven:
<spring-cloud.version>Finchley.RELEASE</spring-cloud.version>
so
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-openfeign</artifactId>
<version>2.0.0.RELEASE</version>
Я изменяю весь импорт:
import org.springframework.cloud.netflix.feign.EnableFeignClients;
import org.springframework.cloud.netflix.feign.FeignClient;
на
import org.springframework.cloud.openfeign.EnableFeignClients;
import org.springframework.cloud.openfeign.FeignClient;
Я использую этот интерфейс:
@FeignClient(value = "COMPANY", fallbackFactory = CompanyClientFallbackFactory.class, configuration = FeignConfiguration.class)
public interface CompanyClient extends CompanyApi {
}
Когда я запускаю свои тесты JUnit (с контекстом Spring), у меня появляется эта ошибка сейчас (не в Springboot 1.xy и старом пакете netflix):
The bean 'COMPANY.FeignClientSpecification', defined in null, could not be registered. A bean with that name has already been defined in null and overriding is disabled.
Полный след:
