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

MainTopology代码如下:

package rexel.topo;

import org.apache.storm.LocalCluster;
import org.apache.storm.StormSubmitter;
import org.apache.storm.topology.TopologyBuilder;

public class MainTopology {
    private static PropertiesUtils propertiesUtils = PropertiesUtils.getInstance();

    public static void main(String[] args) throws Exception {
        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();

            e.printStackTrace();
        }
        return Base64.encodeBase64String(rawHmac);
    }
}

 

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
