在使用OpenFeign调用时，如果目标服务只有一个，而我们想将调用接口分成两个service类，有时间会报这个错：
FeignClientSpecification’ could not be registered. A bean with that name has already been defined and overriding is disabled

这个是因为我们在两个service类上面添加注解时：@FeignClient 时，里面的name值设置为同一个了，但是又因为请求的日标服务是同一个，name必须一样，这个时间该怎么办呢？可以使用另一个属性来标识不同的service,就是：contextId，如下所示：

@FeignClient(contextId = "friend", name = "${vm.config.scene-server-name}", path = "friend")
public interface FriendFeignService {
}

@FeignClient(contextId = "user", name = "${vm.config.scene-server-name}", path = "user")
public interface UserFeignService {
}
