Logging 如何使用log4j在日志中打印spring kafka配置

有没有办法使用log4j在日志中记录所有spring kafka配置？我尝试在我的应用程序log4j2.yml中使用以下记录器配置，我可以看到所有信息和调试日志，但看不到配置。 -名称：org.springframework.kafka 可加性：false 级别：信息/调试 附录REF： -参考：一些附录

提前感谢您的帮助。

我认为您只需要担心应用于Apache Kafka客户端的属性。这也将涵盖Spring Kafka配置。为此，您只需为

org.apache.kafka.clients

类别配置

INFO

这是我一次测试的日志：

这对我来说很好

Configutation:
  name: Default

  Properties:
    Property:
      name: log-path
      value: "logs"

  Appenders:

    Console:
      name: Console_Appender
      target: SYSTEM_OUT
      PatternLayout:
        pattern: "[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n"

  Loggers:

      Root:
        level: warn
        AppenderRef:
          - ref: Console_Appender

      Logger:
        - name: org.apache.kafka
          level: info
          AppenderRef:
            - ref: Console_Appender

我知道org.apache.kafka会记录所有kafka客户端属性，但我想记录Spring kafka属性。示例如果我使用以下Spring Kafka道具配置应用程序，我应该能够在日志中看到这些配置，但这些道具不会显示为“org.apache.Kafka”的一部分Spring:Kafka:consumer:enable auto commit:false listener:ack mode:record某些Spring引导属性（特别是

消费者

和

生产者

）设置卡夫卡属性；例如，代码>启用自动提交< /COD>在卡夫卡属性中设置<代码>启用.Auto.Prime<代码>属性。我们目前不提供一种内置机制来记录Spring特定属性，如“代码> ACK模式< /代码>，但您可以添加自己的。请随意打开A，我们将考虑将其添加到未来。release.Contributions是受欢迎的。感谢Gary确认日志中没有打印Spring Kafka属性的默认方法。一个选项将是..感谢我更改package

org.apache.Kafka.clients的日志级别

有助于避免服务启动时日志混乱。正如Hoxton.SR1中使用Spring Cloud Stream的Kafka消费者所做的那样具有信息日志级别的大量配置日志。
