java - 如何获取用于日志记录的kafka consumer-id

Question

在我的应用程序中，我使用 spring-kafka 来消费来自 kafka 服务器的消息，但是我从控制台消费者那里得到了所有活跃的消费者线程的 consumer-id

TOPIC            PARTITION  CURRENT-OFFSET  LOG-END-OFFSET  LAG             CONSUMER-ID                                    HOST            CLIENT-ID
easytest-events    9          247367          247367          0             p3-S14-0-e6a1d3cb-8ab3-435f-9f53-5081a6e8f812 /10.66.56.129   p3-S14-0

有没有办法通过代码获取consumer-id，以便我可以比较它们

Answer 1

consumer-id 似乎是附加了 UUID 的 client-id - 因此您可以只使用 client-id(您可以将其设置为任何您想要的)。 Spring 会添加-0、-1 等。

您可以在分配分区时在日志中看到线程数...
