利用Springcloud怎么熔斷hystrix服務(wù)

@Service
public class PaymentHystrixService {
 @HystrixCommand(fallbackMethod = "paymentCircuitBreaker_fallback",commandProperties = {
      @HystrixProperty(name = "circuitBreaker.enabled", value = "true"),       //是否開啟斷路器
      @HystrixProperty(name = "circuitBreaker.requestVolumeThreshold", value = "10"),  //請求數(shù)達(dá)到后才計算
      @HystrixProperty(name = "circuitBreaker.sleepWindowInMilliseconds", value = "10000"), //休眠時間窗
      @HystrixProperty(name = "circuitBreaker.errorThresholdPercentage", value = "60"), //錯誤率達(dá)到多少跳閘
  })
  public String paymentCirtuitBreaker(@PathVariable("id")Integer id){
   if(id<0){
     throw new RuntimeException("****id不能為負(fù)數(shù)");
   }
   String randomNum= IdUtil.simpleUUID();

   return Thread.currentThread().getName()+"\t"+"調(diào)用成功，編號"+randomNum;

  }
  public String paymentCircuitBreaker_fallback(@PathVariable("id")Integer id){
    return "id不能為負(fù)數(shù)，請稍后重試，o(╥﹏╥)o+"+id;
  }
