storm java.io.NotSerializableException

估计有2年没搞storm了，今天由于工作需要重新搞一次，

不过需要使用最新版本的storm了。使用的是1.2.3版本，

写了程序，报了一个错误，如下

13886 [main] INFO  o.a.s.d.s.Supervisor - Starting supervisor with id 87f0e450-46bf-4545-b86f-2a9f961ad24d at host vm1.

工程结构如下：

MainTopology代码如下：

        PropertiesBean propertiesBean = propertiesUtils.readProperties();
        if (propertiesBean == null) {
            return;
        }

        TopologyBuilder builder = new TopologyBuilder();
        builder.setSpout("ThingSpout", new ThingSpout(), 1);
        builder.setBolt("ThingBolt", new ThingBolt(), 1).shuffleGrouping("ThingSpout");

        Config config = new Config();
        config.setNumWorkers(1);
        config.setMessageTimeoutSecs(60);
        config.setMaxSpoutPending(100);
        config.setNumAckers(1);if (Boolean.valueOf(args[0])) {
            StormSubmitter.submitTopology("MainTopology", config, builder.createTopology());
        } else {
            LocalCluster localCluster = new LocalCluster();

ThingBolt代码如下：

package rexel.topo;

import java.util.Map;
import org.apache.storm.task.OutputCollector;
import org.apache.storm.task.TopologyContext;
import org.apache.storm.topology.OutputFieldsDeclarer;
import org.apache.storm.topology.base.BaseRichBolt;
import org.apache.storm.tuple.Tuple;

public class ThingBolt extends BaseRichBolt {
    private static final long serialVersionUID = 1L;

    @Override
    public void prepare(Map map, TopologyContext topologyContext, OutputCollector outputCollector) {

    }

    @Override
    public void execute(Tuple tuple) {
        String content = new String(tuple.getBinaryByField("body"));
        System.out.println("receive message: {" + content + "}");
    }

    @Override
    public void declareOutputFields(OutputFieldsDeclarer outputFieldsDeclarer) {

    }
}

错误的原因是在Spout中有没有序列化的代码，将以下两个对象前面加上static之后，问题解决。

private MessageListener messageListener → private static MessageListener messageListener

private JmsConnectionListener myJmsConnectionListener → private static JmsConnectionListener myJmsConnectionListener
