укажите ниже конфигурацию Kafka для локального сервера @Bean public ConsumerFactory consumerFactory () {Map config = new HashMap <> ();
config.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, "127.0.0.1:9092");
config.put(ConsumerConfig.GROUP_ID_CONFIG, "group_id");
config.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
config.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
return new DefaultKafkaConsumerFactory<>(config);
}
@Bean
public ConcurrentKafkaListenerContainerFactory<String, String> kafkaListenerContainerFactory() {
ConcurrentKafkaListenerContainerFactory<String, String> factory = new
ConcurrentKafkaListenerContainerFactory();
factory.setConsumerFactory(consumerFactory());
return factory;
}
here I need to change the topic as a dynamic content
@KafkaListener(topics = "mytopic")
private void consume2(String Data) {
String userID = null;
String topic = null;
String message = null;
System.out.println(Data);
}
