kafka0.10 生产者案例

1;首先创建topic 
./bin/kafka-topics.sh -zookeeper zk1:2181,zk2:2181,zk3:2181 -topic test -replication-factor 3 -partition 3 -create
2:查看topic
./bin/kafka-topics.sh -zookeeper zk1:2181,zk2:2181,zk3:2181 -list

3:然后执行如下代码

package com.xx.bigdata.kafkaTool;

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

import java.util.Properties;
import java.util.UUID;

public class Producer {
    public static void main(String[] args) {
        Properties properties = new Properties() {{
            put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, "zk1:9092,zk2:9092,zk3:9092");
            put(ProducerConfig.ACKS_CONFIG, "all");
            put(ProducerConfig.RETRIES_CONFIG, 0);
            put(ProducerConfig.BATCH_SIZE_CONFIG, 16384);
            put(ProducerConfig.LINGER_MS_CONFIG, 1);
            put(ProducerConfig.BUFFER_MEMORY_CONFIG, 33554432);
            put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.StringSerializer");
            put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.StringSerializer");
        }};
        KafkaProducer<String, String> producer = new KafkaProducer<>(properties);
        while (true) {
            try {
                Thread.sleep(500);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            producer.send(new ProducerRecord<>("test", UUID.randomUUID().toString(), UUID.randomUUID().toString()));
        }
    }
}
