Java-Atmosphere长轮询只发送第一条消息

我正在尝试实现一种通知机制，其中客户端连接到服务器并接收更新

每个用户都像这样连接到一个服务端点

@ManagedService(path = "/chat/{userId}")

    @Ready
    public void onReady(final AtmosphereResource resource) {
        Broadcaster broadcaster = BroadcasterFactory.getDefault().lookup(userId,true);
        broadcaster.addAtmosphereResource(resource);
    }

@RequestMapping(value = "/ws2/{userId}", method = RequestMethod.GET)
    public void test(@PathVariable("userId") String userId) {
        Broadcaster broadcaster = BroadcasterFactory.getDefault().lookup(userId,true);
        broadcaster.broadcast(new Message(userId, "User id : "));
    }

当他们连接时，他们会像这样在广播公司注册

@ManagedService(path = "/chat/{userId}")

    @Ready
    public void onReady(final AtmosphereResource resource) {
        Broadcaster broadcaster = BroadcasterFactory.getDefault().lookup(userId,true);
        broadcaster.addAtmosphereResource(resource);
    }

@RequestMapping(value = "/ws2/{userId}", method = RequestMethod.GET)
    public void test(@PathVariable("userId") String userId) {
        Broadcaster broadcaster = BroadcasterFactory.getDefault().lookup(userId,true);
        broadcaster.broadcast(new Message(userId, "User id : "));
    }

例如，当我想从REST端点发送消息时，我是这样做的

@ManagedService(path = "/chat/{userId}")

    @Ready
    public void onReady(final AtmosphereResource resource) {
        Broadcaster broadcaster = BroadcasterFactory.getDefault().lookup(userId,true);
        broadcaster.addAtmosphereResource(resource);
    }

@RequestMapping(value = "/ws2/{userId}", method = RequestMethod.GET)
    public void test(@PathVariable("userId") String userId) {
        Broadcaster broadcaster = BroadcasterFactory.getDefault().lookup(userId,true);
        broadcaster.broadcast(new Message(userId, "User id : "));
    }

当我使用websocket实现时，它工作得非常好。 当我更改为长轮询并调用此REST方法时，只发送第一条消息，其他消息将被忽略，没有任何错误或日志。 在这种情况下我能做什么
