Hystrix降级失败，关闭服务端之后，消费端没有降级，而是报connect timed out，如何解决？

Question

controller代码

@RestController
public class HystrixCont {

    @Autowired
    private HystrixService hystrixService;

    @GetMapping("/contsumer/hystrix/zc")
    public  String  hystrix_ok(){
      return   hystrixService.hystrix_ok()+ UUID.randomUUID().toString();
    }

    @HystrixCommand(fallbackMethod = "hystrix_3m_two",commandProperties = {
            @HystrixProperty(name="execution.isolation.thread.timeoutInMilliseconds",value="1500")
    })
    @GetMapping("/contsumer/hystrix/3m")
    public  String  hystrix_3m(){
        return  hystrixService.hystrix_3m();
    }

    public  String  hystrix_3m_two(){
        return  "超时";
    }
}

opfeign接口代码

@Component
@FeignClient(value = "cloud-provider-service",fallbackFactory = FlHystrix.class)
public interface HystrixService {



    @GetMapping("/payment/hystrix/zc")
    public  String  hystrix_ok();



    @GetMapping("/payment/hystrix/3m")
    public  String  hystrix_3m();
}

实现HystrixService，做降级的代码

@Component
public class FlHystrix implements HystrixService{

    @Override
    public String hystrix_ok() {
        return "hystrix_ok";
    }

    @Override
    public String hystrix_3m() {
        return "hystrix_3m";
    }
}

主启动类

@SpringBootApplication
@EnableEurekaClient
@EnableFeignClients
@EnableHystrix
public class HystrixOrder80 {
    public static void main(String[] args) {
        SpringApplication.run(HystrixOrder80.class,args);
    }
}

yml配置

server:
  port: 8000

spring:
  application:
    name: cloud-consumer-order
#  cloud:
#    circuitbreaker:
#      hystrix:
#        enabled: true

eureka:
  client:
    register-with-eureka: true
    fetchRegistry: true
    service-url:
        defaultZone: http://eureka7001.com:7001/eureka

#feign结合hystrix使用
feign:
  hystrix:
    enabled: true

其中，我看到有人说feign没有与hystrix一起了，开启hystrix的方式改变了，变成我注释的那段

#  cloud:
#    circuitbreaker:
#      hystrix:
#        enabled: true

但是还是不生效。

我在消费端controller做@HystrixCommand的超时降级没有问题。opfeign也没问题。
但是关闭服务端，就不调用继承的类的方法。
