    Properties properties = new Properties();

properties.put("security.protocol", "SASL_PLAINTEXT");
properties.put("sasl.mechanism", "PLAIN");

properties.setProperty("key.serializer", StringSerializer.class.getName());
properties.setProperty("value.serializer", StringSerializer.class.getName());

KafkaProducer producer = new KafkaProducer(properties);
ProducerRecord record = new ProducerRecord("test", "test_value");
producer.send(record);
producer.flush();
producer.close();

Конфигурация Kafka server.properties приведена ниже.
