Unable to read same message on same topic by multiple consumers - spring-boot

Question

I am publishing a message to topicX. To consume this message by multiple consumers, I have written following ConsumerConfig (Note, each consumer has different groupd_id.
#EnableKafka
#Configuration
public class ConsumerConfig {
#Value("${spring.kafka.bootstrap-servers}")
private String bootstrapServers;
#Bean
public Map<String, Object> consumerConfigs(String groupId) {
Map<String, Object> props = new HashMap<>();
props.put(BOOTSTRAP_SERVERS_CONFIG, bootstrapServers);
props.put(GROUP_ID_CONFIG, "my.groupid." + groupId);
props.put(AUTO_OFFSET_RESET_CONFIG, "earliest");
return props;
}
#Bean
public ConsumerFactory<String, Car> consumerFactory(String groupId) {
return new DefaultKafkaConsumerFactory<>(consumerConfigs(groupId), new StringDeserializer(),
new JsonDeserializer<>(Car.class));
}
#Bean
public ConcurrentKafkaListenerContainerFactory<String, Car> consumerOneKafkaListenerContainerFactory() {
ConcurrentKafkaListenerContainerFactory<String, Car> factory = new ConcurrentKafkaListenerContainerFactory<>();
factory.setConsumerFactory(consumerFactory("one"));
return factory;
}
#Bean
public ConcurrentKafkaListenerContainerFactory<String, Car> consumerTwoKafkaListenerContainerFactory() {
ConcurrentKafkaListenerContainerFactory<String, Car> factory = new ConcurrentKafkaListenerContainerFactory<>();
factory.setConsumerFactory(consumerFactory("two"));
return factory;
}
}
And then on specific consumer, I have added following annotation (specified the group id and container factory)
#KafkaListener(id = "my.groupid.one", topics = "${app.topic.topicname}", containerFactory = "consumerOneKafkaListenerContainerFactory")
But when i publish the message, only one consumer consumes it. How can i i configure kafka so that each published message is consumed by multiple consumers?
I have tried this code with 1 partition and n partitions (where n = number of consumers) and yet i am having this issue.
UPDATE
Here is my topic producer class
#Service
#Slf4j
public class TopicProducer {
#Autowired
private KafkaTemplate<String, TopicPayload> kafkaTemplate;
public void send(String topicName, TopicPayload payload) {
log.info("sending message={} to topic={}", payload, topicName);
kafkaTemplate.send(topicName, payload);
}
}
And here is my TopicProducerConfig
#Configuration
public class TopicProducerConfig {
#Value("${spring.kafka.bootstrap-servers}")
private String bootstrapServers;
#Bean
public Map<String, Object> producerConfigs() {
Map<String, Object> props = new HashMap<>();
props.put(BOOTSTRAP_SERVERS_CONFIG, bootstrapServers);
props.put(KEY_SERIALIZER_CLASS_CONFIG, StringSerializer.class);
props.put(VALUE_SERIALIZER_CLASS_CONFIG, JsonSerializer.class);
return props;
}
#Bean
public ProducerFactory<String, TopicPayload> producerFactory() {
return new DefaultKafkaProducerFactory<>(producerConfigs());
}
#Bean
public KafkaTemplate<String, TopicPayload> kafkaTemplate() {
return new KafkaTemplate<>(producerFactory());
}
}
I post a message by calling producer.send(topicName, payload).
