在Actor中使用case class来接收多个参数。这样可以在actorOf()时，以Actor构造函数的形式传递多个参数。

示例代码如下：

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

// 定义case class来接收多个参数 case class GreetingMessage(name: String, message: String)

class GreetingActor extends Actor {

def receive = { case greeting: GreetingMessage => println(s"Hello ${greeting.name}, ${greeting.message}") } }

object Main { def main(args: Array[String]): Unit = { val system = ActorSystem("HelloSystem")

// 使用case class来传递多个参数
val greeting = GreetingMessage("John", "how are you?")

val greetingActor = system.actorOf(Props[GreetingActor], "greetingActor")

// 将Actor构造函数的形式传递多个参数
greetingActor ! greeting

system.terminate()

} }
