we can also send and receive custom Java objects. This requires configuring the appropriate serializer in ProducerFactory and a deserializer in ConsumerFactory.

@Bean
public ProducerFactory<String, Greeting> greetingProducerFactory() {
    // ...
    configProps.put(
      ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, 
      JsonSerializer.class);
    return new DefaultKafkaProducerFactory<>(configProps);
}

@Bean
public KafkaTemplate<String, Greeting> greetingKafkaTemplate() {
    return new KafkaTemplate<>(greetingProducerFactory());
}
kafkaTemplate.send(topicName, new Greeting("Hello", "World"));
