Springcloud hystrix服务熔断和dashboard如何实现

@Service
public class PaymentHystrixService {
 @HystrixCommand(fallbackMethod = "paymentCircuitBreaker_fallback",commandProperties = {
      @HystrixProperty(name = "circuitBreaker.enabled", value = "true"),       //是否开启断路器
      @HystrixProperty(name = "circuitBreaker.requestVolumeThreshold", value = "10"),  //请求数达到后才计算
      @HystrixProperty(name = "circuitBreaker.sleepWindowInMilliseconds", value = "10000"), //休眠时间窗
      @HystrixProperty(name = "circuitBreaker.errorThresholdPercentage", value = "60"), //错误率达到多少跳闸
  })
  public String paymentCirtuitBreaker(@PathVariable("id")Integer id){
   if(id<0){
     throw new RuntimeException("****id不能为负数");
   }
   String randomNum= IdUtil.simpleUUID();

   return Thread.currentThread().getName()+"\t"+"调用成功，编号"+randomNum;

  }
  public String paymentCircuitBreaker_fallback(@PathVariable("id")Integer id){
    return "id不能为负数，请稍后重试，o(╥﹏╥)o+"+id;
  }
