示例1: MqttDispatchingListener

//设置package包名称以及导入依赖的类
package mqtt

import akka.actor.{ActorPath, ActorSystem}
import mqtt.MqttListenerMessage.ConsumeMessage
import org.eclipse.paho.client.mqttv3.{IMqttDeliveryToken, MqttCallback, MqttMessage}
import play.api.Logger


class MqttDispatchingListener(actorSystem: ActorSystem) extends MqttCallback {
  var listeners: List[ActorPath] = List.empty

  override def deliveryComplete(token: IMqttDeliveryToken): Unit = {}
  override def connectionLost(cause: Throwable): Unit = {}

  def addListener(listener:ActorPath): Unit = {
    listeners = listener :: listeners
  }

  override def messageArrived(topic: String, message: MqttMessage): Unit = {
    val msgStr = new String(message.getPayload)
    Logger.debug(s"Mqtt topic $topic received $msgStr")

    listeners.foreach(actorSystem.actorSelection(_) ! ConsumeMessage(topic, msgStr))
  }
}

object MqttListenerMessage {
  case class Ping()
  case class ConsumeMessage(receivedTopic: String, message: String)

//设置package包名称以及导入依赖的类
package service

import controllers.socket.LightSocketActor
import model.Message
import org.eclipse.paho.client.mqttv3.{IMqttDeliveryToken, MqttCallback, MqttClient, MqttMessage}


object SubscribeService {
  val client = new MqttClient(brokerUrl, MqttClient.generateClientId(), persistence)

  def subscribe(): Unit = {
    client.connect()

    // TODO: Change topic
    client.subscribe(topic)

    val callback = new MqttCallback {
      override def deliveryComplete(token: IMqttDeliveryToken): Unit = {
        play.Logger.debug("Delivery complete!")
      }

      override def connectionLost(cause: Throwable): Unit = {
        play.Logger.debug("Connection to socket lost")
        LightSocketActor.sendMessage(Message("Connection lost"))
      }

      override def messageArrived(topic: String, message: MqttMessage): Unit = {
        play.Logger.debug(s"A message arrived: ${new String(message.getPayload)}")
        LightSocketActor.sendMessage(Message(new String(message.getPayload)))
      }
    }

    client.setCallback(callback)
