配置:  //添加retry

@Configuration
public class FeignConfig {
    @Bean
    public Retryer feignRetryer(){
        return new Retryer.Default(,TimeUnit.SECONDS.toMillis(),);
    }
}

使用:

@FeignClient(name = "tracking-milestone-service", configuration = FeignConfig.class)
public interface TrackingServiceClient {

    @RequestMapping(value = "/ws/search/orders", method = RequestMethod.GET)
    public ResponseEntity<JSONObject> searchByTypesAndNumbers(@RequestParam("type") String type,
            @RequestParam("customer") String customer, @RequestParam("status") JSONArray status,
            @RequestParam("fromTime") String fromTime, @RequestParam("toTime") String toTime,
            @RequestParam("numberFromTime") String numberFromTime, @RequestParam("numberToTime") String numberToTime);
