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)
} 示例2: SubscribeService
//设置package包名称以及导入依赖的类
package service
