log4j2 - 一个appender中不同层次的不同布局

Question

我想为不同的消息层次使用不同布局的appender。我想出的所有解决方案都需要两个不同的appender，像这里：

<Appender type="Console" name="STDOUT_D"> 
    <Layout type="PatternLayout" pattern="[%-5p] %d %c - %m%n"/> 
    <Filters> 
     <ThresholdFilter level="fatal" onMatch="ACCEPT" onMismatch="NEUTRAL"/> 
     <ThresholdFilter level="error" onMatch="ACCEPT" onMismatch="NEUTRAL"/> 
     <ThresholdFilter level="warn" onMatch="DENY" onMismatch="NEUTRAL"/> 
     <ThresholdFilter level="info" onMatch="DENY" onMismatch="NEUTRAL"/> 
     <ThresholdFilter level="debug" onMatch="ACCEPT" onMismatch="NEUTRAL"/> 
    </Filters> 
</Appender> 
<Appender type="Console" name="STDOUT"> 
    <Layout type="PatternLayout" pattern="[%-5p] %d %-60.60c - %m%n"/> 
    <Filters> 
     <ThresholdFilter level="fatal" onMatch="DENY" onMismatch="NEUTRAL"/> 
     <ThresholdFilter level="error" onMatch="DENY" onMismatch="NEUTRAL"/> 
     <ThresholdFilter level="warn" onMatch="ACCEPT" onMismatch="NEUTRAL"/> 
     <ThresholdFilter level="info" onMatch="ACCEPT" onMismatch="NEUTRAL"/> 
     <ThresholdFilter level="debug" onMatch="DENY" onMismatch="NEUTRAL"/> 
    </Filters> 
</Appender> 

想法？

我在严格模式下使用XML配置。

我archieved使用ScriptPatternSelector

<Appender type="Console" name="STDOUT"> 
    <PatternLayout> 
    <ScriptPatternSelector defaultPattern="[%-5level] %c{1.} %C{1.}.%M.%L %msg%n"> 
     <Script name="selector" language="groovy"><![CDATA[ 
      if (logEvent.getLevel() == org.apache.logging.log4j.Level.DEBUG) 
       return "DEBUG" 
      else 
       return "INFO" 
      ]]> 
     </Script> 
     <PatternMatch key="DEBUG" pattern="[%-5p] %d %c - %m%n"/> 
     <PatternMatch key="INFO" pattern="[%-5p] %d %-60.60c - %m%n"/> 
    </ScriptPatternSelector> 
    </PatternLayout> 
</Appender> 

这一结果
