          <type>jar</type>
        </dependency>
      </dependencies>
    </plugin>
  </plugins>
</build>

三、定义Schema 将kafka获取的消息作过滤处理。

package com.simon.storm;

import backtype.storm.spout.Scheme;
import backtype.storm.tuple.Fields;
import backtype.storm.tuple.Values;

import java.io.UnsupportedEncodingException;
import java.util.List;

/**
 * Created by Administrator on 2018/1/10.
 * 对kafka出来的数据转换成字符串，
 * 接下来我们想办法来处理strom清洗之后的数据
 */
public class MessageScheme implements Scheme {
    public List<Object> deserialize(byte[] bytes) {
        try {
             String msg = new String(bytes, "UTF-8");
             return new Values(msg);
         } catch (UnsupportedEncodingException e) {
             e.printStackTrace();
         }
        return null;
    }

    public Fields getOutputFields() {
        return new Fields("msg");
    }
}

四、定义bolt

将数据处理并保存到redis中

package com.simon.storm;

import backtype.storm.task.TopologyContext;
import backtype.storm.topology.BasicOutputCollector;
import backtype.storm.topology.OutputFieldsDeclarer;
import backtype.storm.topology.base.BaseBasicBolt;
import backtype.storm.tuple.Fields;
import backtype.storm.tuple.Tuple;
import backtype.storm.tuple.Values;
import redis.clients.jedis.Jedis;

import java.io.DataOutputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Map;

/**
 * Created by Administrator on 2018/1/10.
 *
 * 把输出的消息放到文件redis缓存中
 */
public class SenqueceBolt  extends BaseBasicBolt {

    private Jedis jedis ;

    @Override
    public void prepare(Map stormConf, TopologyContext context) {
        super.prepare(stormConf, context);
        jedis = new Jedis("master",6379);
    }

    public void execute(Tuple tuple, BasicOutputCollector basicOutputCollector) {
        String word = (String) tuple.getValue(0);
        /*String out = "output:" + word;*/
        System.out.println(word);

        if(word != null){
            //将url写入到redis的一个zset集合中
            // 参数1： zset的主键 参数2：要增加的分数 参数3：url中的网站部分——site
            word = word.toUpperCase();
            jedis.zincrby("words", 1, word);
        }

        basicOutputCollector.emit(new Values(word));
    }

    public void declareOutputFields(OutputFieldsDeclarer outputFieldsDeclarer) {
        outputFieldsDeclarer.declare(new Fields("message"));
    }
}

五、定义Topology 提交本地或集群

package com.simon.storm;

import backtype.storm.Config;
import backtype.storm.LocalCluster;
import backtype.storm.StormSubmitter;
import backtype.storm.generated.AlreadyAliveException;
import backtype.storm.generated.InvalidTopologyException;
import backtype.storm.spout.SchemeAsMultiScheme;
import backtype.storm.topology.TopologyBuilder;
import backtype.storm.utils.Utils;
import storm.kafka.BrokerHosts;
import storm.kafka.KafkaSpout;
import storm.kafka.SpoutConfig;
import storm.kafka.ZkHosts;
import storm.kafka.bolt.KafkaBolt;
import java.util.HashMap;
import java.util.Map;
public class StormKafkaTopo {
    public static void main( String[] args ) {
        BrokerHosts brokerHosts = new ZkHosts("master:2181,slave01:2181,slave02:2181");
        SpoutConfig spoutConfig = new SpoutConfig(brokerHosts, "hello", "/kafka", "kafkaspout");
         Config conf = new Config();
         Map<String, String> map = new HashMap<String, String>();
         map.put("metadata.broker.list", "10.10.34.36:9092");
         map.put("serializer.class", "kafka.serializer.StringEncoder");
         conf.put("kafka.broker.properties", map);
         //conf.put("topic", "topic2");
         spoutConfig.scheme = new SchemeAsMultiScheme(new MessageScheme());
         TopologyBuilder builder = new TopologyBuilder();
         builder.setSpout("spout", new KafkaSpout(spoutConfig));
         builder.setBolt("bolt", new SenqueceBolt()).shuffleGrouping("spout");
         builder.setBolt("kafkabolt", new KafkaBolt<String, Integer>()).shuffleGrouping("bolt");
         if(args != null && args.length > 0) {
                //提交到集群运行
                 try {
                     StormSubmitter.submitTopology(args[0], conf, builder.createTopology());
                 } catch (AlreadyAliveException e) {
                     e.printStackTrace();
                 } catch (InvalidTopologyException e) {
                     e.printStackTrace();
                 }
             } else {
                 //本地模式运行
                 LocalCluster cluster = new LocalCluster();
                 cluster.submitTopology("Topotest1121", conf, builder.createTopology());
                 Utils.sleep(1000000);
                 cluster.killTopology("Topotest1121");
                 cluster.shutdown();
             }
     }
}
