我开发了一个定制的Kafka制作人，作为一个maven项目，我使用的依赖关系是：

<dependency>
    <groupId>org.apache.kafka</groupId>
    <artifactId>kafka-clients</artifactId>
    <version>0.8.2.0</version>
</dependency>

我使用的导入：

import org.apache.kafka.clients.producer.KafkaProducer;
import org.apache.kafka.clients.producer.ProducerConfig;
import org.apache.kafka.clients.producer.ProducerRecord;
import org.apache.kafka.common.serialization.ByteArraySerializer;
import org.apache.kafka.common.serialization.StringSerializer;

我的生产者消息发送代码片段：

Properties props = new Properties();
props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, zkConnection);
props.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, StringSerializer.class);
props.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, ByteArraySerializer.class);

byte[] byteData = null;
File myInputFile = new File(...);
try (InputStream inputStream = new FileInputStream(myInputFile)) {
    byteData = IOUtils.toByteArray(inputStream);
}

try (KafkaProducer<String, byte[]> producer = new KafkaProducer<String, byte[]>(props)) {
    producer.send(new ProducerRecord<String, byte[]>(topic, byteData));
}
