Question

我正在使用Spring Boot和Kafka，并希望收听现有和正在运行的经纪人和主题上的消息。

application.yml配置如下：

spring:
  kafka:
    topic:
        boot: my_topic
    bootstrap-servers: hostname:9092
    properties:
      security.protocol: SSL
    consumer:
      auto-offset-reset: earliest
      group-id: my_group
      enable-auto-commit: false
      fetch-max-wait: 500
      max-poll-records: 1

抛出以下错误：

不可能更改kafka经纪人和制作人的配置。 Spring Boot中的客户端kafka配置中是否有任何缺失可以添加以解决此问题？

Answer 1

您的代理似乎未配置SSL;如果我在客户端设置SSL，我会得到同样的错误;我的经纪人没有使用SSL ......
