我是新来Kafka，我有这样的要求，我有很多服务器产生大量的日志，我想创造多个生产者和消费者。
我已经实现了单一生产者和消费者可以任何人请帮助我了解我将如何创建多个生产者和消费者。
这是我的生产者和消费者代码
producer:-

public class MessageProducerExample {

    public static void main(String[] args) {

        System.out.println("Hello World");

         Properties props = new Properties();
         props.put("bootstrap.servers", "localhost: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");

         Producer<String, String> producer = new KafkaProducer<String, String>(props);
         for(int i = 0; i < 100; i++)
             producer.send(new ProducerRecord<String, String>("test", "Msg"+Integer.toString(i),"Msg"+Integer.toString(i)));

         producer.close();

    }
}

消费者：-

public class MessageConsumerExample {

    public static void main(String[] args) {

        String topicName = args[0];

         Properties props = new Properties();
         props.put("bootstrap.servers", "localhost:9092");
         props.put("group.id", "test-consumer-group");
         props.put("enable.auto.commit", "true");
         props.put("auto.commit.interval.ms", "1000");
         props.put("session.timeout.ms", "30000");
         props.put("key.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");
         props.put("value.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");
         props.put("auto.offset.reset","earliest");

         System.out.println("TopicName="+topicName);

         KafkaConsumer<String, String> consumer = new KafkaConsumer<String, String>(props);
         consumer.subscribe(Arrays.asList(topicName));

         while (true) {
             ConsumerRecords<String, String> records = consumer.poll(100);
             System.out.println("records"+records.count());
             for (ConsumerRecord<String, String> record : records)
                 //System.out.println("offset = %d, key = %s, value = %s", record.offset(), record.key(), record.value());
                 System.out.println("RECORD_OFFSET"+record.offset()+"RECORD_KEY" +record.key()+"RECORD_VALUE "+record.value());
         }
        }
}

提前谢谢。
