机器人配置错误

Question

我正在开发 GTalk 机器人。我还没有完成，但到目前为止，我的机器人工作正常。自从我第一次运行这个机器人以来，有一件事让我很恼火。当我向 gtalk 机器人发送 IM 消息时，它总是响应“机器人配置错误”消息。我不明白为什么会这样。即使在我收到配置错误消息后，它仍然会像正常情况一样进行并运行正常。如果我在收到错误消息几秒钟后发送另一条 IM 消息，我将不会收到机器人配置错误响应。如果我等几分钟让它“重置”。 “重置”机器人后，如果我再次向机器人发送另一条 IM 消息。我将得到配置错误响应。我完全不知道为什么我不断收到这些错误消息。我的代码中甚至没有“机器人配置错误”字符串。它必须来自 Smack API 或 GTalk 服务器或其他东西。

这是我的代码片段：

    public GtalkBot(){
        presence = null;

        ConnectionConfiguration connConfig = new ConnectionConfiguration("talk.google.com", 5222, domain);
        //ConnectionConfiguration connConfig = new ConnectionConfiguration("talk.google.com", 5222);
        connConfig.setReconnectionAllowed(true);
        conn = new XMPPConnection(connConfig);

        chatProcessor = new GChatBufferProcessor(conn);
        logger.info(this.getClass().getSimpleName()+" created");
    } /* Gtalkbot */


    public void run() {
        while(true){
            try {
                login();

                logger.error("failed to connect to "+conn.getHost(), xe);
                this.incrementalNap();
                continue; // skip the rest of the loop and retry from the top
            }

            // start the chat message processor thread
            chatProcessor.start();

            // create gtalk chat listener
            this.createChatListener();

            while(conn.isConnected()){
                /* stuck in this loop while connected, not sure if 
                this is the right way to do it. */
                try {

        conn.sendPacket(presence);
    } /* login */


    public void createChatListener(){
        GtalkMessageListener msgListener = new GtalkMessageListener();
        //PacketFilter filter = new MessageTypeFilter(Message.Type.chat);
        PacketFilter filter = new PacketTypeFilter(Message.class);
        conn.addPacketListener(msgListener, filter);
    } /* createChatListener */


    public void incrementalNap(){
        if(sleepCount < MAX_SLEEP_COUNT){
            sleepSec = sleepSec << 1; // multiply by 2
            sleepCount++;
        }

        logger.debug("Sleeping for "+(sleepSec/1000)+" seconds ...");

        try {
            Thread.sleep(sleepSec);
        } catch (InterruptedException e){
            e.printStackTrace();
        }
    } /*  incrementalNap */

}

提前感谢各位。
