アプリケーションを spring-kafka (spring-integration-kafka ではない) と統合しています。プロジェクトの春のドキュメントは次のとおりです。http://docs.spring.io/spring-kafka/docs/1.0.1.RELEASE/reference/htmlsingle
プロデューサーは完全に動作しますが、コンシューマーはメッセージを消費していません。任意のポインター。
これが私の構成です：
@EnableKafka
public class MyConfig {
@Value("${kafka.broker.list}") // List of servers server:port,
private String kafkaBrokerList;
@Bean
public KafkaListenerContainerFactory<ConcurrentMessageListenerContainer<Integer, Message>> kafkaListenerContainerFactory() {
ConcurrentKafkaListenerContainerFactory<Integer, Message> factory = new ConcurrentKafkaListenerContainerFactory<>();
factory.setConsumerFactory(consumerFactory());
factory.setConcurrency(12);
factory.getContainerProperties().setPollTimeout(3000);
factory.getContainerProperties().setIdleEventInterval(60000L);
factory.setAutoStartup(Boolean.TRUE);
factory.setMessageConverter(new StringJsonMessageConverter());
return factory;
}
@Bean
public ConsumerFactory<Integer, Message> consumerFactory() {
JsonDeserializer<Message> messageJsonDeserializer = new JsonDeserializer<>(Message.class);
return new DefaultKafkaConsumerFactory<>(consumerConfigs(), new IntegerDeserializer(), messageJsonDeserializer);
}
@Bean
public Map<String, Object> consumerConfigs() {
Map<String, Object> props = new HashMap<>();
props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, kafkaBrokerList);
props.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG, true);
props.put(ConsumerConfig.AUTO_COMMIT_INTERVAL_MS_CONFIG, 10000);
props.put(ConsumerConfig.SESSION_TIMEOUT_MS_CONFIG, 15000);
props.put(ConsumerConfig.CONNECTIONS_MAX_IDLE_MS_CONFIG, 60000);
props.put(ConsumerConfig.RETRY_BACKOFF_MS_CONFIG, 10000);
return props;
}
@KafkaListener(topics = "myTopic", containerFactory = "kafkaListenerContainerFactory")
public void listen(@Payload Message message) {
System.out.println(message);
}
}

ゲイリーさん、返信ありがとうございます。ログに例外はありません。またKafkaTemplate、同様の構成で試してみたところ、メッセージをキューに発行できましたが、消費者にとってはうまくいきませんでした。Message オブジェクトの代わりに String を使用するようにコードを変更しています。ログの一部は次のとおりです。
