логическая идея
Я настраивал приложение Springboot, которое создает сообщения для брокера Kafka, который работает в контейнере Docker.
Docker Setup of Kafka Broker
Я следовал за следующим шагом к установке Cafka Broker с Aronge Theme и Presser -Broker с Aromer с Antry с Antry с Antry с Antry с Antry с Antry с Antry с Antry с Antry с Antry с Antry с Antry с Antry с Antry -Broker с Arner -Broker с Arting Arner -Broker. />docker run -d -p 9092:9020 --name broker apache/kafka:latest
docker exec --workdir /opt/kafka/bin/ -it broker sh
./kafka-topics.sh --bootstrap-server localhost:9092 --create --topic SCH-dispatcher
./kafka-console-consumer.sh --topic SCH-dispatcher --from-beginning --bootstrap-server localhost:9092
< /code>
code < /h1>
У меня есть следующие свойства, настроенные в моем приложении.# KAFKA CONFIGURATION
trax.kafka.address=localhost:9092
trax.kafka.dispatch-topic=SCH-dispatcher
< /code>
Рядом с этим у меня есть класс кафкаконфигурации, который создает компонент для создания соединения кафки. < /p>

@Bean

Map configProps = new HashMap();
configProps.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, kafkaAddress);

configProps.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, StringSerializer.class);

return new DefaultKafkaProducerFactory(configProps);
}
@Bean
public KafkaTemplate kafkaTemplate() {
return new KafkaTemplate(producerFactory());
}
}
< /code>
Рядом с этим у меня есть класс производителя кафки: < /p>

@Component
@RequiredArgsConstructor
@Slf4j
public class DispatcherKafkaProducer {
private final KafkaTemplate kafkaTemplate;
public void send(String topic, String message) {
CompletableFuture future = kafkaTemplate.send(topic, message);
future.whenComplete((result, ex) -> {
throw new IllegalArgumentException("Exception occurred during sending message to Kafka topic.", ex);
});
}
}

Сценарий проблемы < /h1>
Когда я запускаю приложение, я вижу, как запускается по продюсеру Kafka, но на моем кафке-кончителе не возвращает одно сообщение.2025-08-21T16:58:00.035+02:00 INFO 10328 --- [Scheduler] [ scheduling-1] o.a.k.clients.producer.ProducerConfig : ProducerConfig values:

Я слишком незнаком, чтобы самостоятельно обнаружить основную причину проблемы. Итак, я ищу совета, почему мои сообщения, созданные кафкой, не получены брокером или почему брокер не потребляет сообщения.
