yaml - Log4j2 : How to configure multiple Appender with same type in Yaml configuration

Question

我正在尝试在同一YAML配置中使用2 RollingRandomAccessFile。我可以用XML来做，但是不能用YAML来做。结果，我想要两个文件“application.log”和“payload.log”。

这是我的工作XML配置:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="debug">
    <Appenders>

        <Console name="CONSOLE" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
        </Console>

        <RollingRandomAccessFile name="PAYLOAD" fileName="logs/payload.log"
                                 filePattern="logs/$${date:yyyy-MM}/payload-%d{MM-dd-yyyy}-%i.log.gz">
            <PatternLayout>
                <pattern>[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n</pattern>
            </PatternLayout>
            <Policies>
                <SizeBasedTriggeringPolicy size="1 KB"/>
            </Policies>
        </RollingRandomAccessFile>

        <RollingRandomAccessFile name="APPLICATION" fileName="logs/application.log"
                                 filePattern="logs/$${date:yyyy-MM}/application-%d{MM-dd-yyyy}-%i.log.gz">
            <PatternLayout>
                <pattern>[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n</pattern>
            </PatternLayout>
            <Policies>
                <SizeBasedTriggeringPolicy size="1 KB"/>
            </Policies>
        </RollingRandomAccessFile>

    </Appenders>

    <Loggers>
        <Root level="info" additivity="false">
            <appender-ref ref="CONSOLE" level="trace"/>
            <appender-ref ref="APPLICATION" level="trace"/>
            <appender-ref ref="PAYLOAD" level="trace"/>
        </Root>
    </Loggers>

</Configuration>

这是我无法使用的YAML配置。 RollingRandomAccessFile的第二个声明将覆盖第一个声明，仅产生“application.log”:

Configuration:
  status: debug

  Appenders:
    Console:
      name: CONSOLE
      target: SYSTEM_OUT
      PatternLayout:
        Pattern: "%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"
    RollingRandomAccessFile:
      name: PAYLOAD
      fileName: logs/payload.log
      filePattern: "logs/$${date:yyyy-MM}/payload-%d{MM-dd-yyyy}-%i.log.gz"
      PatternLayout:
        Pattern: "%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"
      Policies:
        SizeBasedTriggeringPolicy:
          size: 1 KB
    RollingRandomAccessFile:
      name: APPLICATION
      fileName: logs/application.log
      filePattern: "logs/$${date:yyyy-MM}/application-%d{MM-dd-yyyy}-%i.log.gz"
      PatternLayout:
        Pattern: "%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"
      Policies:
        SizeBasedTriggeringPolicy:
          size: 1 KB

  Loggers:
    Root:
      level: debug
      AppenderRef:
        - ref: CONSOLE
        - ref: PAYLOAD
        - ref: APPLICATION

这是我尝试在Appender级别使用List的方法，并且没有输出，甚至没有控制台:

Configuration:
  status: debug

  Appenders:
    - Console:
      name: CONSOLE
      target: SYSTEM_OUT
      PatternLayout:
        Pattern: "%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"
    - RollingRandomAccessFile:
      name: PAYLOAD
      fileName: logs/payload.log
      filePattern: "logs/$${date:yyyy-MM}/payload-%d{MM-dd-yyyy}-%i.log.gz"
      PatternLayout:
        Pattern: "%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"
      Policies:
        SizeBasedTriggeringPolicy:
          size: 1 KB
    - RollingRandomAccessFile:
      name: APPLICATION
      fileName: logs/application.log
      filePattern: "logs/$${date:yyyy-MM}/application-%d{MM-dd-yyyy}-%i.log.gz"
      PatternLayout:
        Pattern: "%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"
      Policies:
        SizeBasedTriggeringPolicy:
          size: 1 KB

  Loggers:
    Root:
      level: debug
      AppenderRef:
        - ref: CONSOLE
        - ref: PAYLOAD
        - ref: APPLICATION

如果我将第二个RollingRandomAccessFile替换为RollingFile，它会完美地工作。

我终于找到了解决方案，滥用了名单

Configuration:
  status: debug

  Appenders:
    Console:
      name: CONSOLE
      target: SYSTEM_OUT
      PatternLayout:
        Pattern: "%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"
    RollingRandomAccessFile:
      - name: PAYLOAD
        fileName: logs/payload.log
        filePattern: "logs/$${date:yyyy-MM}/payload-%d{MM-dd-yyyy}-%i.log.gz"
        PatternLayout:
          Pattern: "%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"
        Policies:
          SizeBasedTriggeringPolicy:
            size: 1 KB
      - name: APPLICATION
        fileName: logs/application.log
        filePattern: "logs/$${date:yyyy-MM}/application-%d{MM-dd-yyyy}-%i.log.gz"
        PatternLayout:
          Pattern: "%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"
        Policies:
          SizeBasedTriggeringPolicy:
            size: 1 KB

  Loggers:
    Root:
