ConsumerAPI.Subscribe 只需要执行一次,如果 Subscribe,可能是 SDK 内返回了类似 Busy 类的错误,因此需要先保证 ConsumerAPI.Subscribe 一定成功,成功之后,会返回一个用于订阅的 chan,这个chan需要走 for range or for select 的语句不断消费 chan 里面的实例变化事件,如果 chan 被 sdk 内部逻辑 close 的话,那么就又会走到外层的循环进行再次发起订阅动作,如果内部for发生错误,跳出当前for,继续执行监听事件

阻塞20秒以后再执行,所以先执行上面的,上面的如果20秒还没有执行完,重新执行说明上面的bug,当然是否可以用户自定义,另外20秒是否过长,这个在dubbo yaml配置文件里面可以用户自定义配置

感觉完全没有必要在在外层加一个for
