无法使用传入消息调用侦听器方法，并且 Backoff none 已用完 ConsumerRecord

Question

下面是我对 kafka 侦听器的方法定义，如果收到有效负载的空字符串或空字符串，我想我遇到了以下错误...你能帮忙吗。

 @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) {}

Answer 1

您需要指定不需要负载。

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

无法使用传入消息调用侦听器方法，并且 Backoff none 已用完 ConsumerRecord

Listener method could not be invoked with the incoming message and Backoff none exhausted for ConsumerRecord

apache-kafka

spring-boot
