Actor 생성

 

import akka.actor.{Actor, ActorRef, ActorSystem, Props}

object AkkaMain {
  def main(args: Array[String]): Unit = {
    // name 으로는 alphabet 만 사용 가능 ('-, _, space' 도 사용 불가)
    val actorSystem: ActorSystem = ActorSystem(name = "firstActorSystem")
    println(actorSystem.name)

    class Person(name: String) extends Actor {
      // type Receive = PartialFunction[Any, Unit]
      override def receive: Receive = {
        case "hi" => println(s"Hi, my name is $name")
        case _    =>
      }
    }

    object Person {
      def props(name: String): Props = Props(new Person(name))
    }

//    val person = actorSystem.actorOf(Props(new Person("Bob")))
// actor 를 만들 때 아래처럼 companion object 를 이용하는 것이 권장되는 방법임
    val person: ActorRef = actorSystem.actorOf(Person.props("Bob"))
    person ! "hi"
  }
}
