当我运行命令警报(通知)消息转到除原始发件人之外的所有连接的套接字时,使用事件流代替ArchivedEventStream,我还可以如何发送到原始发件人

这是我的模型和控制器,使用WebSocket

事件模型

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);
}

}
公共类事件模型{
//~~~~~~~~~~~~我们聊聊吧!
最终事件流事件=新事件流(100);
/**
*获取事件
*/
public EventStream getEventStream(){
返回事件;
}
/**
*用户在房间里说了些什么
*/
公共无效警报(通知){
如果(通知==null)返回;
发布(新的EventModel.NotificationEvent(通知));
}
//~~~~~~~~~~~~活动
公共静态抽象类事件{
最终公共字符串类型;
最终公共长时间戳;
发送公共布尔值;
公共事件(字符串类型){
this.sended=false;
this.type=type;
this.timestamp=System.currentTimeMillis();
}
}
公共静态类NotificationEvent扩展了EventModel.Event{
公开最后通知;
公共通知事件(通知){
超级(“通知”);
this.notification=通知;
}
公共用户getReceiver(){
返回通知接收人;
}
}
//事件模型工厂
静态EventModel实例=null;
公共静态事件模型get(){
if(实例==null){
实例=新的EventModel();
}
返回实例;
}
//警报通知
公共静态无效警报(通知){
获取()。_警报(通知);
}
}
这是控制器

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();
            }   
        }
    }
}
}
公共类MyWebSocket扩展了RootController{
公共静态类WebSocket扩展了WebSocketController{
公共静态void echo(长用户ID){
//保安
User=User.findById(userId);
EventModel eventcenter=EventModel.get();
//已连接套接字,请加入聊天室
EventStream eventStrean=eventcenter.getEventStream();
//在插座打开时循环
while(inbound.isOpen()){
//等待事件(入站套接字频道或聊天室消息中出现的内容)
e=等待(Promise.waitor)(
inbound.nextEvent(),
eventStrean.nextEvent()
));
//如果收到任何通知,请处理
for(EventModel.NotificationEvent事件:ClassOf(EventModel.NotificationEvent.class).match(e._2)){
如果(!event.getReceiver().equals(user))继续;
outbound.send(event.notification.toJson());
}      
//案例:插座已关闭
for(WebSocketClose关闭:SocketClose.match(e._1)){
断开连接();
}   
}
}
}
}

要发送给原始发件人,请删除或注释掉此行:

if(!event.getReceiver().equals(user)) continue;

需要注意的一个小问题
