Event-Driven Microservices using Spring boot and Kafka

Comment

We have a couple of building blocks, mainly

Infrastructure (Kafka, Zookeeper)

Producer (Java Spring-Boot Service)

Consumer (Java Spring-Boot Service)

public class ConsumerConfiguration {

  @Value("${kafka.bootstrap-servers}")
  private String bootstrapServers;

  @Bean
  public Map<String, Object> consumerConfigs() {
    Map<String, Object> props = new HashMap<>();
    props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, bootstrapServers);
    props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
    return props;
  }

  @Bean
  public ConsumerFactory<String, String> consumerFactory() {
    return new DefaultKafkaConsumerFactory<>(consumerConfigs());
  }

  @Bean
  public KafkaListenerContainerFactory<ConcurrentMessageListenerContainer<String, String>> kafkaListenerContainerFactory() {
    ConcurrentKafkaListenerContainerFactory<String, String> factory = new ConcurrentKafkaListenerContainerFactory<>();
    factory.setConsumerFactory(consumerFactory());
    return factory;
  }

  @Bean
  public NewTopic timestampTopic() {
    return TopicBuilder.name("timestamp")
                       .build();
  }

}
