一.啟動相關服務

1.啟動Zookeeper服務

2.啟動kafka相關服務

二.程式碼演示（非常簡單，寫一個KafkaProducer）

import java.util.Properties;

import org.apache.kafka.clients.producer.KafkaProducer;
import org.apache.kafka.clients.producer.ProducerRecord;

public class SendDataToKafka {
public static void main(String[] args) {
SendDataToKafka sendDataToKafka = new SendDataToKafka();
sendDataToKafka.send("mysqltest", "", "this is a test data too");
}

public void send(String topic,String key,String data){
Properties props = new Properties();
props.put("bootstrap.servers", "127.0.0.1:9092");
props.put("acks", "all");
props.put("retries", 0);
props.put("batch.size", 16384);
props.put("linger.ms", 1);
props.put("buffer.memory", 33554432);
props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");
props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer");


KafkaProducer<String, String> producer = new KafkaProducer<String,String>(props);
for(int i=1;i<2;i++){
try {
Thread.sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
producer.send(new ProducerRecord<String, String>(topic, ""+i, data));
}
producer.close();
}
}

執行程式碼即可在kafka consumer看到訊息

ps:KafkaProducer類所在的包在kafka根目錄lib下
