我正在尝试将远程 akka 系统连接到播放框架，看起来我的配置有问题。
我有一个 Play 框架控制器类和一个 Akka 演员，因为下面的本地对象是代码：
当我运行时，网页上显示以下消息
[ClassNotFoundException: akka.remote.RemoteActorRefProvider]
In C:\Users\FAISAL\workspace\Rakka\app\controllers\Application.java at line 21.
17 public static Result index() throws InterruptedException {
18
19 System.out.println(" Local Node Called0");
20
21 ActorSystem csystem = ActorSystem.create("Application", ConfigFactory.load().getConfig("LocalNode"));
22 ActorRef localNode = csystem.actorOf(new Props(LocalNode.class));
23
24 System.out.println(" Local Node Called1");
25 localNode.tell("Hello");
这是控制器：
public class Application extends Controller {
public static Result index() throws InterruptedException {
System.out.println(" Local Node Called0");
ActorSystem csystem = ActorSystem.create("Application", ConfigFactory.load().getConfig("LocalNode"));
ActorRef localNode = csystem.actorOf(new Props(LocalNode.class));
System.out.println(" Local Node Called1");
localNode.tell("Hello World");
System.out.println(" Local Node Called2");
Thread.sleep(5000);
csystem.shutdown();
return ok(index.render("I am OK"));
}
}
这是当地的阿卡演员
public class LocalNode extends UntypedActor {
LoggingAdapter log = Logging.getLogger(getContext().system(), this);
Timeout timeout = new Timeout(Duration.parse("5 seconds"));
ActorRef master;
public void preStart()
{
/* Get reference to Master Node*/
master = getContext().actorFor("akka://MasterNode@127.0.0.1:2552/user/master");
}
@Override
public void onReceive(Object message) throws Exception {
System.out.println(" Future called ");
Future<Object> future = Patterns.ask(master , message.toString(), timeout);
String result = (String) Await.result(future, timeout.duration());
log.info("Messagefrom Server", result);
}
}
这是本地播放配置文件
#confige the remote connection
LocalNode {
akka {
actor {
provider = "akka.remote.RemoteActorRefProvider"
}
remote {
transport = "akka.remote.netty.NettyRemoteTransport"
netty {
hostname = "127.0.0.1"
port = 0
}
}
}
}
下面的代码来自远程 akka 系统。
这是远程主控
public class MasterNode implements Bootable
{
final ActorSystem system;
public MasterNode() {
system = ActorSystem.create("MasterNode", ConfigFactory.load()
.getConfig("master"));
ActorRef actor = system.actorOf(new Props(MasterActor.class),"master");
System.out.println(" Master Node is called ");
}
public void startup() {
}
public void shutdown() {
system.shutdown();
}
}
这是远程 akka 演员系统
public class MasterActor extends UntypedActor {
@Override
public void onReceive(Object message) throws Exception {
if (message instanceof String) {
// Get reference to the message sender and reply back
getSender().tell(message + " got something");
}
}
}
这是来自远程 akka 配置
master {
akka {
actor {
provider = "akka.remote.RemoteActorRefProvider"
}
remote {
transport = "akka.remote.netty.NettyRemoteTransport"
netty {
hostname = "127.0.0.1"
port = 2552
}
}
}}
为了运行系统，我首先启动了 Akka 远程系统，然后启动了 Play 2 框架
运行 Play 框架后，我收到以下错误

看起来我没有做对，欢迎任何建议或帮助。
