指定消費的kafka集群

@KafkaListener(topics = "topic-name", containerFactory = "kafkaListenerContainerFactoryK2")public void onEvent(ConsumerRecord<String, String> record) {// 省略}

指定生產者發生的kafka集群

public class KafkaTest {@Autowiredprivate KafkaTemplate<String, String> kafkaTemplate;@Testpublic void test() {ListenableFuture<SendResult<String, String>> result = kafkaTemplate.send("topic", "data");try {SendResult<String, String> value = result.get(2, TimeUnit.SECONDS);System.out.println(value.getProducerRecord());System.out.println(value.getRecordMetadata());} catch (Exception e) {e.printStackTrace();}} }
