你可以把这个supervisor看作是另一个behavioiur，它把你的behaviour包裹在里面。
让我们说你想有以下HelloWorld演员。

object HelloWorldActor {

  sealed trait Command
  case class HelloCommand(name: String) extends Command

  def apply(): Behavior[Command] =
    Behaviors.receiveMessage[Command] { 
      case msg: HelloCommand =>
        println(s"Hello ${msg.name}")
        Behaviors.same
    }

}

现在，您可以用“主管”来“ Package ”这种“行为”

object SupervisedHelloWorldActor {

  sealed trait Command
  case class HelloCommand(name: String) extends Command

  def apply(): Behavior[Command] =
    Behaviors.supervise(
      Behaviors.receiveMessage[Command] { 
        case HelloCommand(name) =>
          println(s"Hello ${name}")
          Behaviors.same
      }
    ).onFailure(onFailure[IllegalStateException](SupervisorStrategy.restart))

}
