Question

如何使用Atmosphere（Meteor）从一个客户端向另一个客户端广播消息？我目前基于流星教程实现此实现

@Override
public void doGet(HttpServletRequest req, HttpServletResponse res) throws IOException {
    Meteor.build(req).addListener(new AtmosphereResourceEventListenerAdapter());
}

@Override
public void doPost(HttpServletRequest req, HttpServletResponse res) throws IOException {
    String body = req.getReader().readLine().trim();
    //some DAO lookups - here I would like to say I want to broadcast only to concrete client
    BroadcasterFactory.getDefault().lookup(DefaultBroadcaster.class, "/*").broadcast(UserDAO.getInstance().getUser(name));
}

Answer 2

我相信另一个解决方案：对于只处理一个客户端，您不需要广播，您可以这样做：

     try
     {
        r.getResponse().write(message);
     }
     catch(IllegalStateException e)
     {
        logger.error("Could not send message through atmosphere " + userId);
     }

其中r是您可以在程序中记忆的资源。

Answer 3

BroadcasterFactory.getDefault().lookup(atmosphereResource.uuid()).broadcast('something');

仅使用Atmosphere向一个客户端广播
