@FeignClient(name = "sndhmg-config-client-producer", fallback = UserConsumerFeignFallback.class)
public interface UserConsumerFeign {

    @GetMapping(path = "user/myName/{name}")
    ResultVo<String> hello(@PathVariable String name);

}

@Component
public class UserConsumerFeignFallback implements UserConsumerFeign {

    @Override
    public ResultVo<String> hello(String name) {
        return new ResultVo<>("feign 调用失败");
    }

}

@Service
public class UserService {

    @Autowired
    RestTemplate restTemplate;

    @Autowired
    LoadBalancerClient loadBalancerClient;

    @Autowired
    UserConsumerFeign userConsumerFeign;

    @Value("${feign.circuitbreaker.enabled}")
    String circuitbreaker;

    @Value("${feign.hystrix.enabled}")
    String hystrix;

    public ResultVo<String> hello(String name) {
        ResponseEntity<ResultVo> resp = restTemplate
                .getForEntity("http://sndhmg-config-client-producer/user/myName/" + name, ResultVo.class);
        return resp.getBody();
    }

    public ResultVo<String> feignHello(String name) {
        return userConsumerFeign.hello(name);
    }

}

feign:
  circuitbreaker:
    enabled: true
  hystrix:
    enabled: true

感觉没有啥问题，但是始终不生效，求指教
