AKKA笔记1

读spark源码，AKKA确实有必要单独研究一下，用在java的项目上也不错

1.maven构建一个akka的java项目，只需要添加一个dependencies

        <dependency>
          <groupId>com.typesafe.akka</groupId>
          <artifactId>akka-actor_2.10</artifactId>
          <version>2.3.14</version>
       </dependency>

 

 

2. 第一个java AKKA消息驱动程序

 

1）构建ActorSystem，发送给自定义的MasterActor

 

import scala.concurrent.Future;

import akka.actor.ActorRef;

import akka.actor.ActorSystem;

import akka.actor.Props;

import akka.apply.actor.MasterActor;

import akka.pattern.Patterns;

 

public class MainTest {

 

public static void main(String[] args) {

ActorSystem as = ActorSystem.create("test");

ActorRef master = as.actorOf(Props.create(MasterActor.class), "master");

master.tell("start", master);

as.awaitTermination();

}

 

}

import akka.actor.ActorRef;

import akka.actor.Props;

import akka.actor.UntypedActor;

 

public class MasterActor extends UntypedActor {

 

@Override

public void onReceive(Object msg) throws Exception {

System.out.println(""+this.getClass().getSimpleName()+"::sender:"+this.getSender()+"  ::self:"+this.getSelf());

 

}

 

}

 

运行结果：
