我使用风暴本地模式没问题，但是会在集群上报告故障。

这是我的代码：

public class NettySpout extends BaseRichSpout {

private static final long serialVersionUID = 1L;
/**
 * colloctor for spout
 */
private SpoutOutputCollector collector;

@Override
public void open(Map map, TopologyContext topologyContext, SpoutOutputCollector spoutOutputCollector) {
    collector=spoutOutputCollector;
    StormServer stormServer=new StormServer();
    stormServer.run();
}

@Override
public void nextTuple() {
    Values tuple;
    try {
        while ((tuple = ServerHandler.queue.take()) != null) {
            collector.emit(tuple);
        }
    } catch (Exception e) {
    }
}

@Override
public void declareOutputFields(OutputFieldsDeclarer outputFieldsDeclarer) {
    outputFieldsDeclarer.declare(new Fields("value","channl"));
}


public class ServerHandler extends ChannelInboundHandlerAdapter{

private static Logger logger = LogManager.getLogger(ServerHandler.class);
public static LinkedBlockingQueue<Values> queue = new LinkedBlockingQueue<Values>();
public static Map<String,ChannelHandlerContext> ctxes;

public void channelRead(ChannelHandlerContext ctx, Object msg)  throws Exception {
    JSONObject message = (JSONObject) msg;
    queue.put(new Values(new StreamData(message.toString().getBytes()), new HashMap<>(ctxes)));

}

我对风暴本身并不了解，但似乎你试图将ChannelHandlerContext（存储在你的Map中）序列化，而不是Serializable。
