playframework每天與Akka運行任務

Question

我正在尋找簡單的示例/手動/使用Akka Aktor PlayFramework與Java中的使用。 我已經試過這個教程： https://www.playframework.com/documentation/2.2.x/JavaAkka 但我不能讓它編譯。

我想在每24個房間計算一些數據並從系統發送一封電子郵件。我想爲它使用Aktor。

我用playFramework 2.2.x的

Answer 1

我的工作液（用於playFramework 2.2.4）的基礎上一篇：https://stackoverflow.com/a/14706767/1066240

在/app/Global.java

我Global.java類

import org.joda.time.DateTime; 
import org.joda.time.Seconds; 

import actions.ValidateApplicationLicence; 
import akka.actor.ActorRef; 
import akka.actor.Props; 
import play.Application; 
import play.GlobalSettings; 
import play.Logger; 
import play.libs.Akka; 
import scala.concurrent.duration.Duration; 

import java.util.concurrent.TimeUnit; 

public class Global extends GlobalSettings { 

    //ActorRef myActor = Akka.system().actorOf(new Props(ValidateApplicationLicence.class)); 

    @Override 
    public void onStart(Application application) { 

     Akka.system().scheduler().schedule(
       Duration.create(20, TimeUnit.SECONDS), 
       Duration.create(5, TimeUnit.SECONDS), 
       new Runnable() { 
        @Override 
        public void run() { 
         Logger.info("After 10 sec and after EVERY 5 sec --- " + controllers.common.Index.getDate(null)); 
        } 
       }, 
       Akka.system().dispatcher() 
     ); 

     Akka.system().scheduler().scheduleOnce(
       Duration.create(10, TimeUnit.MILLISECONDS), 
       new Runnable() { 
        public void run() { 
         Logger.info("ON START --- " + controllers.common.Index.getDate(null)); 
        } 
       }, 
       Akka.system().dispatcher() 
     ); 
//  Akka.system().scheduler().schedule(
//    Duration.create(0, TimeUnit.MILLISECONDS), //Initial delay 0 milliseconds 
//    Duration.create(30, TimeUnit.MINUTES),  //Frequency 30 minutes 
//    myActor, 
//    "tick", 
//    Akka.system().dispatcher(), 
//    null 
//  ); 
    } 
    public static int nextExecutionInSeconds(int hour, int minute){ 
     return Seconds.secondsBetween(
       new DateTime(), 
       nextExecution(hour, minute) 
     ).getSeconds(); 
    } 

    public static DateTime nextExecution(int hour, int minute){ 
     DateTime next = new DateTime() 
       .withHourOfDay(hour) 
       .withMinuteOfHour(minute) 
       .withSecondOfMinute(0) 
       .withMillisOfSecond(0); 

     return (next.isBeforeNow()) 
       ? next.plusHours(24) 
       : next; 
    } 
}

沒有爲Play 2.0.4 in Java在2.1幾件事情變了樣，反正（主要是進口）
