取而代之使用EventStream代替ArchivedEventStream，当我运行命令alert（notification）消息时，转到除原始发件人之外的所有连接的套接字，我怎么也可以发送给原始发件人。播放框架1.2.5 Websocket
这里是我的模型和控制器，使用的WebSocket
EventModel
public class EventModel {
// ~~~~~~~~~ Let's chat!
final EventStream<EventModel.Event> events = new EventStream<EventModel.Event>(100);
/**
* Get the event
*/
public EventStream<EventModel.Event> getEventStream() {
return events;
}
/**
* A user say something on the room
*/
public void _alert(Notification notification){
if(notification == null) return;
events.publish(new EventModel.NotificationEvent(notification));
}
// ~~~~~~~~~ Events
public static abstract class Event {
final public String type;
final public Long timestamp;
public boolean sended;
public Event(String type) {
this.sended = false;
this.type = type;
this.timestamp = System.currentTimeMillis();
}
}
public static class NotificationEvent extends EventModel.Event{
public final Notification notification;
public NotificationEvent(Notification notification) {
super("notification");
this.notification = notification;
}
public User getReceiver(){
return notification.receiver;
}
}
// EventModel factory
static EventModel instance = null;
public static EventModel get() {
if(instance == null) {
instance = new EventModel();
}
return instance;
}
//Alert notification
public static void alert(Notification notification){
get()._alert(notification);
}
}
这里是控制器
public class MyWebSocket extends RootController {
public static class WebSocket extends WebSocketController {
public static void echo(Long userId) {
//Security
User user = User.findById(userId);
EventModel eventCentre = EventModel.get();
// Socket connected, join the chat room
EventStream<EventModel.Event> eventStrean = eventCentre.getEventStream();
// Loop while the socket is open
while(inbound.isOpen()) {
// Wait for an event (either something coming on the inbound socket channel, or ChatRoom messages)
Either<WebSocketEvent,EventModel.Event> e = await(Promise.waitEither(
inbound.nextEvent(),
eventStrean.nextEvent()
));
//Handle if get any notification
for(EventModel.NotificationEvent event: ClassOf(EventModel.NotificationEvent.class).match(e._2)) {
if(!event.getReceiver().equals(user)) continue;
outbound.send(event.notification.toJson());
}
// Case: The socket has been closed
for(WebSocketClose closed: SocketClosed.match(e._1)) {
disconnect();
}
}
}
}
}
