无法使用传入消息调用侦听器方法，并且对于 ConsumerRecord 没有耗尽 Backoff

Question

下面是我对 kafka 侦听器的方法定义，如果接收到有效负载的 null 或空字符串，我想我会遇到错误...请您帮忙。

 @KafkaListener(topics = "${kafka.consumer-topic-name.reservation}", groupId = "${kafka.consumer-group-id.test}",
        containerFactory = "kafkaListenerContainerFactory",autoStartup = "${kafka.auto-start.consumer.tets}")
public void consumeReservation(String payload, @Header(KafkaHeaders.RECEIVED_TOPIC) String topic,
                               @Header(KafkaHeaders.RECEIVED_MESSAGE_KEY) String kafkaKey) {}

你需要指定payload不是必需的。

@Payload(required = false) String payload, ...
