監督策略

我們遵循兩種監督策略來監督任何演員：

1. 一對一策略

2. 一對一策略

case object ResumeException extends Exception
 
case object StopException extends Exception
case object RestartException extends Exception
 
override val supervisorStrategy =
 OneForOneStrategy(maxNrOfRetries = 10, withinTimeRange = 1 second){
 case ResumeException => Resume
 case RestartException => Restart
 case StopException => Stop
 case _: Exception => Escalate
 }
