spring cloud feign注入失败，basePackages加了也没有起作用

Question

package com.example.eurekaclient;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.circuitbreaker.EnableCircuitBreaker;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.hystrix.EnableHystrix;
import org.springframework.cloud.openfeign.EnableFeignClients;
import org.springframework.context.annotation.ComponentScan;
//import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;

@SpringBootApplication
@EnableDiscoveryClient
@EnableEurekaClient
@EnableFeignClients(basePackages ={"com.example.eurekaclient.common"})
@EnableHystrix
//@EnableHystrixDashboard
@EnableCircuitBreaker
public class EurekaclientApplication {

    public static void main(String[] args) {
        SpringApplication.run(EurekaclientApplication.class, args);
    }

}

package com.example.eurekaclient.common;

import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;

/**

@FeignClient(name = "SHOP-SERVER")
@Component
public interface HelloRemote {
    @GetMapping(value = "/hello")
    String hello(@RequestParam(value = "name")String name);
}
