Hystrix：为什么rollingStats.timeInMilliseconds 没有生效？

如何解决Hystrix：为什么rollingStats.timeInMilliseconds 没有生效？

这是我做过的实验设置： rollingStats.timeInMilliseconds: 100 sleepWindowInMilliseconds: 200000 错误阈值百分比：20 请求量阈值：1

我的目的是创建一个场景，在 1 次失败后，它将立即进入 sleep window ，因此除非 200 秒结束，否则它不会执行 run。但是我看到的是，它在第​​一次失败后尝试了 3 秒以上，这意味着它一直在调用 run 方法。我一定是错了。请给我一些指导。
