object SimpleAkkaTest {

  def main(args: Array[String]) {
    val system = ActorSystem.create("system")
    val work =system.actorOf(Props[Worker],"worker-1")
    work ! 1
  }

}
class Worker extends Actor {
  override def receive = {
    case 1=> println("1")
    case _ => println("_")
  }
}

解决方案：项目->open module setting->Modules->Dependencies  加上scala sdk的library
