YML文件里需要开启OpenFeign客户端超时控制
ribbon:
  #指的是建立连接所用时间,适用于网络状况正常情况下,两端连接所用时间
  ReadTimeout:  5000
  #指的是建立连接后从服务器读取可用资源所用时间
  ConnectTimeout: 5000

@Component
@FeignClient(value = "CLOUD-PAYMENT-SERVICE")
public interface PaymentFeignService {
    @GetMapping("/payment/getPaymentById/{id}")
    public CommonResult<Payment> getPaymentById(@PathVariable("id")Long id);
    @GetMapping("/payment/timeout")
    public String timeout();
}
