Configuring Topics

Comment

With the introduction of AdminClient in Kafka, we can now create topics programmatically.

We need to add the KafkaAdmin Spring bean, which will automatically add topics for all beans of type NewTopic:

@Configuration
public class KafkaTopicConfig {
    
    @Value(value = "${spring.kafka.bootstrap-servers}")
    private String bootstrapAddress;

    @Bean
    public KafkaAdmin kafkaAdmin() {
        Map<String, Object> configs = new HashMap<>();
        configs.put(AdminClientConfig.BOOTSTRAP_SERVERS_CONFIG, bootstrapAddress);
        return new KafkaAdmin(configs);
    }
    
    @Bean
    public NewTopic topic1() {
         return new NewTopic("baeldung", 1, (short) 1);
    }
}
