我有@FeignClient声明ea.jar：

@FeignClient(name = "ea")
public interface AdvertGroupRemoteService {

    @RequestMapping(value = "/group/{groupId}")
    AdvertGroupVO findByGroupId(@PathVariable("groupId") Integer adGroupId);
}

我将此 jar 添加为 maven 依赖项，然后注入它：

@RestController
public class TestCtr {

    @Autowired
    private AdvertGroupRemoteService advertGroupRemoteService;
}

我总是得到NoSuchBeanDefinitionException：

Caused by: org.springframework.beans.factory.BeanCreationException: Could not autowire field: private cn.com.sina.alan.ms.ea.api.service.AdvertGroupRemoteService cn.com.sina.alan.gateway.controller.TestCtr.advertGroupRemoteService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [cn.com.sina.alan.ms.ea.api.service.AdvertGroupRemoteService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

但是，如果我将@FeignClient声明移到同一个项目中（不作为 jar 依赖项添加），这个异常就消失了。

这个我不太清楚，求助
