我正在尝试创建一个自定义的优先级邮箱,该邮箱使用akka类型,根据邮件的类型来确定邮件的优先级。下面是我创建参与者并向其发送邮件的代码。但是,邮件是按照接收的顺序进行处理的,而不是按照自定义邮箱定义的顺序。
package com.akka.prac
import akka.actor.typed.{ActorSystem, Behavior, DispatcherSelector, Props, Settings}
import akka.actor.typed.scaladsl.Behaviors
import akka.dispatch.{PriorityGenerator, UnboundedPriorityMailbox}
import com.typesafe.config.{Config, ConfigFactory}
object PriorityMailBoxTyped extends App {
val config = ConfigFactory.load("applicationtyped.conf")
val actorSystem = ActorSystem(
MyPriorityActorTyped.receive,
"PriorityMailBox",
config,
DispatcherSelector.fromConfig("prio-dispatcher")
)
actorSystem ! DoubleMessage(6.0)
actorSystem ! IntMessage(1)
actorSystem ! DoubleMessage(5.0)
actorSystem ! IntMessage(3)
actorSystem ! StringMessage("Hello")
actorSystem ! IntMessage(5)
actorSystem ! StringMessage("I am priority actor")
actorSystem ! StringMessage(
"I process string messages first,then integer, long and others"
)
}
class MyPriorityActorMailBoxTyped(settings: Settings, config: Config)
extends UnboundedPriorityMailbox(
// Create a new PriorityGenerator,lower prio means more important
PriorityGenerator {
// Int Messages
case x: IntMessage => 1
// String Messages
case x: StringMessage => 0
// Long messages
case x: LongMessage => 2
// other messages
case x: DoubleMessage => 3
case _ => 4
}
)
trait MyMessage
case class IntMessage(x: Int) extends MyMessage
case class LongMessage(x: Long) extends MyMessage
case class StringMessage(x: String) extends MyMessage
case class DoubleMessage(x: Double) extends MyMessage
object MyPriorityActorTyped {
def receive: Behavior[MyMessage] = Behaviors.receive { (context, message) =>
message match {
case IntMessage(x) => println(x)
case StringMessage(x) => println(x)
case LongMessage(x) => println(x)
case DoubleMessage(x) => println(x)
case _ => println()
}
Behaviors.same
}
}
配置文件
prio-dispatcher {
mailbox-type = "com.akka.prac.MyPriorityActorMailBoxTyped"
}
同样的例子也适用于 akka 经典。我在这里错过了什么?

这似乎是一个bug,现在已在2.6.14中修复。
Justed对它进行了测试,它可以与documentation的配置配合使用:
