What are topics in Apache Kafka?

Comment

A stream of messages that belong to a particular category is called a topic in Kafka. Kafka stores data in topics that are split into partitions.

@Component
@KafkaListener(id = "multiGroup", topics = "multitype")
public class MultiTypeKafkaListener {

    @KafkaHandler
    public void handleGreeting(Greeting greeting) {
        System.out.println("Greeting received: " + greeting);
    }

    @KafkaHandler
    public void handleF(Farewell farewell) {
        System.out.println("Farewell received: " + farewell);
    }

    @KafkaHandler(isDefault = true)
    public void unknown(Object object) {
        System.out.println("Unkown type received: " + object);
    }
}
