Atmosphere Java Servlet Server 发送事件

这是我第一次使用氛围，对我来说非常困难。我想要的是，用户从我的API(Java Servlet/Tomcat(收到一条推送消息。

我正在使用jquery.atmosphere.js和以下应用程序代码：

checkForMenuUpdates: function () {
        var self = this;
        checkUpdates();
        function checkUpdates() {
            var request = {url: path.apiPath + 'user.checkUpdates?token=' + token,                    
                logLevel: 'debug',
                'enableXDR': true,
                transport: 'sse',
                trackMessageLength: "false",
                fallbackTransport: 'long-polling'};
            request.onOpen = function (response) {
            };
            request.onMessage = function (response) {
            }
            var socket = jqueryAtmosphere;
            var subSocket = socket.subscribe(request);
        }
    },

服务器端：控制器：

  else if ("user.checkUpdates".equals(pathInfo)) {
            try {
              AtmosphereBroadcaster atmo=new AtmosphereBroadcaster();
              atmo.subscribe(response);
                //ServerSentEvents updates = new ServerSentEvents();
                //updates.establishConnection(token.getUserId(), response, callback);
            } catch (Exception ex) {
                ErrorHandler error = new ErrorHandler();
                error.Error400(response, callback);
            }
        }

"广播公司"：

private @PathParam("token")
Broadcaster topic;
public SuspendResponse<String> subscribe(HttpServletResponse httpResponse) {
    StandardResponse res = new StandardResponse();
    httpResponse = res.standardResponseSSE(httpResponse);
    return new SuspendResponse.SuspendResponseBuilder<String>()
            .broadcaster(topic)
            .outputComments(true)
            .addListener(new EventsLogger())
            .build();
}
public static void push(String message, String topic) {
    Collection<Broadcaster> broadcasters = BroadcasterFactory.getDefault().lookupAll();
    for (Broadcaster b : broadcasters) {
        System.out.println(b.toString());
    }
    System.out.println("Request to push- Message: " + message + ", Topic: " + topic);
    Broadcaster b = null;
    if (null != (b = BroadcasterFactory.getDefault().lookup(JerseyBroadcaster.class, topic))) {
        System.out.println("Request to push- Message: " + message + ", Topic: " + topic);
        b.broadcast(message + "'n");
    }
}
private class EventsLogger implements AtmosphereResourceEventListener {
    @Override
    public void onPreSuspend(AtmosphereResourceEvent are) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }
    @Override
    public void onSuspend(AtmosphereResourceEvent are) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }
    @Override
    public void onResume(AtmosphereResourceEvent are) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }
    @Override
    public void onDisconnect(AtmosphereResourceEvent are) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }
    @Override
    public void onBroadcast(AtmosphereResourceEvent are) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }
    @Override
    public void onThrowable(AtmosphereResourceEvent are) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }
    @Override
    public void onClose(AtmosphereResourceEvent are) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }
    @Override
    public void onHeartbeat(AtmosphereResourceEvent are) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }
}

和标准响应：

  public HttpServletResponse standardResponseSSE(HttpServletResponse response) {        
    response.setContentType("text/event-stream");
    response.setCharacterEncoding("UTF-8");
    response.setHeader("Pragma", "no-cache");
    response.setHeader("Access-Control-Allow-Origin", "*");
    response.setDateHeader("Expires", -1);
    return response;
}

我从chrome控制台得到以下输出：

上交所成功开业jquery.atmosphere.js？bust=6539327597711.235：3171 SSE 重新连接最大尝试次数达到 6

对我来说，这听起来好像没有回复信息。我有一个非常基本的例子(https://weblogs.java.net/blog/swchan2/archive/2014/05/21/server-sent-events-async-servlet-example(，它工作正常。但对我来说，SSE 不适用于大气框架。

那么这里有什么意义呢？我做错了什么？

编辑：

我知道javascript代码很奇怪 - 它的"正在建设中":)

当然 - 当我将此代码添加到事件记录器时，它正在工作：

public EventsLogger(HttpServletResponse response) {
        PrintWriter write = null;
        try {
            write = response.getWriter();
            while (true) {
                write.write("data:Test 'n'n");
                write.flush();
                Thread.sleep(1000);
            }
        } catch (IOException ex) {
            Logger.getLogger(AtmosphereBroadcaster.class.getName()).log(Level.SEVERE, null, ex);
        } catch (InterruptedException ex) {
            Logger.getLogger(AtmosphereBroadcaster.class.getName()).log(Level.SEVERE, null, ex);
        } finally {
            write.close();
        }
    }

这是心跳未正确发送的问题 - 如何解决这个问题？
