使用此配置设置kafka consumer

kafkaconfig:
  acks: 1
  autoCommit: true
  bootstrapServers: example.com:9092
  topic: item
  groupId: EWok-group
  keyDeserializer: org.apache.kafka.common.serialization.StringDeserializer
  valueDeserializer: org.apache.kafka.common.serialization.StringDeserializer
  maxPollRecords: 1
  pollMillisTime: 15
  retries: 5
  heartBeatInterval: 300
  sessionTimeout: 100000
  maxPollInterval: 30000

代码

卡夫卡版本：Kafka-clients-2.0.1

您能建议任何一个Kafka消费的配置是什么样子的吗？

我已经将System.exit（0）放在源代码中的其他位置。这就是为什么消费者已经离开组并标记为关闭的原因

我已从源代码中删除System.exit（0）。现在它工作正常。

这是否回答了您的问题？这完全类似于重复到标记的问题这不是重复的问题。我没有在while循环中关闭消费者，但我仅在异常将引发时关闭消费者。为什么不将捕获放在循环之外，然后关闭消费者@用户6903099
