我有个小问题。我想从windows java producer脚本连接到vm centos上的kafka服务器。
在config/server.properties中，我有一行代码：

listeners=PLAINTEXT://0.0.0.0:9092
advertised.listeners=PLAINTEXT://<public ip>:9092

（例如：advised.listeners）=plaintext://192.239.83.27:9092)
我仍然无法在windows上生成来自producer的消息。在虚拟盒上，我在网络设置中设置了“allow all”选项
无法运行kafka服务器，持续运行时出现警告：[controller id=0，targetbrokerid=0]无法建立到节点0的连接。代理可能不可用（org.apache.kafka.clients.networkclient）。
请帮忙：p

以及我在windows上的java代码：

public class TwitterProducer {
Logger logger = LoggerFactory.getLogger(TwitterProducer.class.getName());
String consumerKey = "xxx";
String consumerSecret = "xxx";
String token = "xxx";
String secret = "xxx";
public TwitterProducer() {}
public static void main(String[] args) {
    new TwitterProducer().run();
}
public void run()
{
    logger.info("Setup");
    /**Set up your blocking queues: Be sure to size these properly based on expected TPS of your stream */
    BlockingQueue<String> msgQueue = new LinkedBlockingQueue<String>(1000);
    // create a twitter client
    Client client = createTwitterClient(msgQueue);
    // Attempts to establish a connection.
    client.connect();
    // create a kafka producer
    KafkaProducer<String, String> producer = createKafkaProducer();
    // on a different thread, or multiple different threads....
    while (!client.isDone()) {
        String msg = null;
        try {
            msg = msgQueue.poll(5, TimeUnit.SECONDS);
        } catch (InterruptedException e) {
            e.printStackTrace();
            client.stop();
        }
        if(msg != null){
            logger.info(msg);
            producer.send(new ProducerRecord<String, String>("twitter_tweets", null, msg), new Callback() {
                public void onCompletion(RecordMetadata recordMetadata, Exception e) {
                    if (e != null){
                        logger.error("Something bad happened", e);
                    }
                }
            });
        }
    }
    logger.info("End of application");
}
public Client createTwitterClient(BlockingQueue<String> msgQueue)

    Client hosebirdClient = builder.build();
    return hosebirdClient;
}
