小编Seb*_* Le的帖子

我开始在我的项目中使用spring-integration-kafka,我可以生成和使用来自Kafka的消息.但是现在,我希望向特定分区生成消息,并且还消耗来自特定分区的消息.

示例我想生成到分区3的消息,而消费只会从分区3接收消息.

到目前为止,我的主题有8个分区,我可以向特定分区生成消息,但我还没有找到配置消费者的方法,只接收来自特定分区的消息.

所以关于如何使用spring-integration-kafka配置使用者的任何建议,或者其他任何需要与KafkaConsumer.java类配合使用的建议都可以从特定分区接收消息.

谢谢.

这是我的代码:
