如何使用log4j在日志中打印spring kafka配置

Question

有没有办法使用log4j记录日志中的所有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，但不能看到配置。 - name：org.springframework.kafka additivity：false level：info / debug AppenderRef： - ref：SOME_APPENDER提前感谢您的帮助。

我认为你真的只需要担心应用于Apache Kafka客户端的属性。这也将涵盖Spring Kafka配置。为此，您只需要为INFO类别配置org.apache.kafka.clients。

这是我的一个测试的日志：

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

和
