                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

二、自定义bolt

package jiankunking.kafkajstorm.bolts;


import backtype.storm.topology.BasicOutputCollector;
import backtype.storm.topology.OutputFieldsDeclarer;
import backtype.storm.topology.base.BaseBasicBolt;
import backtype.storm.tuple.Tuple;
import backtype.storm.tuple.TupleImplExt;
import jiankunking.kafkajstorm.util.ByteUtil;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.io.UnsupportedEncodingException;




/**
 * Created by jiankunking on 2017/4/19 16:47.
 */
public class CustomBolt extends BaseBasicBolt

    protected final Logger logger = LoggerFactory.getLogger(CustomBolt.class);

    public void execute(Tuple input, BasicOutputCollector collector) {
        try {
            String ss=ByteUtil.getStringFromByteArray((byte[]) ((TupleImplExt) input).get("bytes"));
            System.out.println(ss);
            logger.info(ss);
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
    }

    public void declareOutputFields(OutputFieldsDeclarer declarer) {
        System.out.println("declareOutputFields");
    }
}

三、自定义拓扑图入口类

package jiankunking.kafkajstorm.topologies;


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.topology.TopologyBuilder;
import com.alibaba.jstorm.client.ConfigExtension;
import jiankunking.kafkajstorm.bolts.CustomBolt;
import jiankunking.kafkajstorm.kafka.KafkaSpout;
import jiankunking.kafkajstorm.kafka.KafkaSpoutConfig;
import jiankunking.kafkajstorm.util.PropertiesUtil;

import java.util.Map;

/**
 * Created by jiankunking on 2017/4/19 16:27.
 * 拓扑图 入口类
 */
public class CustomCounterTopology

    /**
     * 入口类，即提交任务的类
     *
     * @throws InterruptedException
     * @throws AlreadyAliveException
     * @throws
    public static void main(String[] args) throws AlreadyAliveException, InvalidTopologyException {
        System.out.println("11111");
        PropertiesUtil propertiesUtil = new PropertiesUtil("/application.properties", false);
        Map propsMap = propertiesUtil.getAllProperty();
        KafkaSpoutConfig spoutConfig = new KafkaSpoutConfig(propertiesUtil.getProps());
        spoutConfig.configure(propsMap);
        TopologyBuilder builder = new TopologyBuilder();
        builder.setSpout("kafkaSpout", new KafkaSpout(spoutConfig));
        builder.setBolt("customBolt", new CustomBolt(), 1).shuffleGrouping("kafkaSpout");
        //Configuration
        Config conf = new Config();
        conf.setDebug(false);
        //指定使用logback.xml
        //需要把logback.xml文件放到jstorm conf目录下
        ConfigExtension.setUserDefinedLogbackConf(conf, "%JSTORM_HOME%/conf/logback.xml");
        if (args != null && args.length > 0) {
            //提交到集群运行
            StormSubmitter.submitTopologyWithProgressBar("customCounterTopology", conf, builder.createTopology());
        } else {
            conf.setMaxTaskParallelism(3);
            //本地模式运行
            LocalCluster cluster = new LocalCluster();
            cluster.submitTopology("CustomCounterTopology", conf, builder.createTopology());
        }
    }
}

四、配置文件application.properties

# kafka
# kafka 消费组
kafka.client.id=kafkaspoutid
kafka.broker.partitions=4
kafka.fetch.from.beginning=false
kafka.topic=test_one
kafka.broker.hosts=10.10.10.10:9092
kafka.zookeeper.hosts=10.10.10.10:2181

storm.zookeeper.root=/kafka

小注：

1、jstorm kafka插件源码集成

需要到jstorm的github官网：​​https://github.com/alibaba/jstorm/releases​​中找到你需要使用的release版本，下载源码，将其中的插件源码集成到你自己的项目中，插件源码位置如下图：

2、logback的使用

jstorm 2.1.1之后，jstorm默认使用了logback作为日志框架，logback在一般使用时是兼容log4j的，也就是说log4j可以直接桥接到logback，具体为：

a. 添加slf4j-api, log4j-over-slf4j和logback依赖（其实加了logback依赖之后就不需要加slf4j-api依赖了），具体：

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.5</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>log4j-over-slf4j</artifactId>
    <version>1.7.10</version>
</dependency>
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.0.13</version>
</dependency>

b. 排除pom中所有的slf4j-log4j12的依赖，因为slf4j-log4j12跟log4j-over-slf4j是冲突的：

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
    <version>1.7.5</version>
    <scope>provided</scope>
</dependency>

这里版本一般是1.7.5，但是还要具体看你的应用pom仲裁出的版本。

理论上，这样就能够把log4j桥接到slf4j。
