如何使用JsonFormat自定义序列化程序来序列化属于case类的akka "actorRef“？

import play.api.libs.json._
import akka.actor.ActorRef

implicit val actorRefFormat: Format[ActorRef] = new Format[ActorRef] {
  override def writes(actorRef: ActorRef): JsValue = JsString(actorRef.path.toString)

  override def reads(json: JsValue): JsResult[ActorRef] = json match {
    case JsString(path) => JsSuccess(system.actorSelection(path).resolveOne())
    case _ => JsError("Invalid actorRef format")
  }
}

import play.api.libs.json.Json

// 导入自定义的JsonFormat
import actorRefFormat._

// 创建一个包含"actorRef"的case类
case class MyMessage(name: String, actor: ActorRef)

// 序列化为JSON字符串
val message = MyMessage("test", actorRef)
val jsonString = Json.toJson(message).toString

// 反序列化为对象
val json = Json.parse(jsonString)
val deserializedMessage = json.as[MyMessage]
