CircuitBreakerOpenException即使服务启动

Question

我正在尝试访问在其他服务器上托管的给定服务。  我可以使用邮递员访问此服务。但是当我尝试在项目中访问此服务时，有时即使服务启动，我也会收到CircuitBreakerOpenException。这是我的代码

    private CircuitBreaker breaker = new CircuitBreaker().withFailureThreshold(getFailuresNumber()).withSuccessThreshold(getSuccessThreshold()).withDelay(getDelay(), TimeUnit.SECONDS)
        .withTimeout(getTimeOut(), TimeUnit.SECONDS);

   @Resource(name = "cityRestService")
    private CityRestService cityRestService;

    @Override
    public CustomData getHotelInGIvenCity(final String cityId) {
        CustomData result = null;
        if (!StringUtils.isBlank(cityId)) {
            try {
                logger.info("getHotelInGIvenCity >> cityId >> " + cityId + " breaker state " + breaker.getState() + " brkaer >> " + breaker.getTimeout());
                result = buildCity(Failsafe.with(breaker).get(new ContextualCallable<city>() {
                    public List<city> call(ExecutionContext context) throws Exception {
                        List<city> cities = cityRestService.list(null);

                        return cities;
                    }
                }));
            }
            catch (Exception e) {
                logger.info("Could not retrieve city", cityId, e);
            }
        }
        logger.debug("Breaker state is " + breaker.getState());
        return result;
    }
