Migración Netflix fingir en Springboot 1.xa openfeign en Springboot 2.x

sgrillon:

Trato de hacer la migración Springboot 1.xy (Bruselas-SR12) para uso 2.xy I FeignClients

I cambio de configuración Maven:

<spring-cloud.version>Finchley.RELEASE</spring-cloud.version>

entonces

<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-openfeign</artifactId>
<version>2.0.0.RELEASE</version>

Puedo cambiar todas las importaciones:

import org.springframework.cloud.netflix.feign.EnableFeignClients;

import org.springframework.cloud.netflix.feign.FeignClient;

a

import org.springframework.cloud.openfeign.EnableFeignClients;

import org.springframework.cloud.openfeign.FeignClient;

Yo uso esta interfaz:

@FeignClient(value = "COMPANY", fallbackFactory = CompanyClientFallbackFactory.class, configuration = FeignConfiguration.class)
public interface CompanyClient extends CompanyApi {
}

Cuando ejecuto mis pruebas JUnit (con el contexto de la primavera), tengo este error ahora (no en Springboot 1.xy y el paquete de Netflix de edad):

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.

Alessandro Dionisi:

Probablemente tiene varias @FeignClientdefiniciones con el mismo atributo de nombre.
