LOG4J2:多个记录器，到多个附加器，处于不同的记录级别 [英] LOG4J2: Multiple loggers, to multiple appenders, at different logging levels

问题描述

我想做的很简单:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
  <Appenders>
    <Console name="Console">
      <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
    </Console>

    <File name = "hibernateFile" fileName = "${artifactId}/logs/hibernate.log"> 
        <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
    </File>

     <File name = "springFile" fileName = "${artifactId}/logs/spring.log"> 
        <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
    </File>

    <File name = "rootFile" fileName = "${artifactId}/logs/root.log"> 
        <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
    </File>        

  </Appenders>
  <Loggers>
    <Root level="trace">
      <AppenderRef ref="Console"/>
      <AppenderRef ref="rootFile"/>
    </Root>

    <Logger name ="org.springframework" level = "debug"> 
        <AppenderRef ref = "Console" level = "info"/>
        <AppenderRef ref = "springFile" level = "debug"/>
    </Logger>

     <Logger name ="org.hibernate" level = "debug"> 
        <AppenderRef ref = "Console" level ="info"/>
        <AppenderRef ref = "hibernateFile" level = "debug"/>
    </Logger>

  </Loggers>
</Configuration>

我只希望重要消息显示在控制台附加程序上，而我希望将详细消息路由到文件附加程序.

I want only important messages to be displayed on my Console appender, while I want detailed messages to be routed to the file appenders.

但是，我不想过滤附加器本身-因为我可能希望在其中路由一些调试或跟踪消息(例如，当我在开发中时).

However, I don't want to filter the appender itself - as I may want to route some debugging or trace messages there (for example when I'm in development).

Apache FAQ 建议我可以按日志记录级别进行过滤在 AppenderRef 上，但正如上面xml中所述，我已经尝试过此操作-并且它仍然将DEBUG级别的消息路由到控制台.

The Apache FAQ suggests that I can just filter by logging level on the AppenderRef, but I've tried this, as outlined in the above xml - and it still routes the DEBUG level messages to the console.

我也尝试过将ThresholdFilter添加到 AppenderRef 中，但这也不能对其进行过滤.

I've also tried adding a ThresholdFilter to the AppenderRef, but that doesn't filter it either.

 <Logger name ="org.hibernate" level = "debug"> 
    <AppenderRef ref = "Console">
         <ThresholdFilter level="info" onMatch="ACCEPT" onMismatch="DENY"/>
    </AppenderRef>
    <AppenderRef ref = "hibernateFile" level = "debug"/>
</Logger>

推荐答案

additivity ="false" 应该可以解决问题:

<Logger name="org.hibernate" level="debug" additivity="false"> 

加性控制是否将日志事件也仍转发到根记录器.

The additivity controls whether a log event is also still forwarded to the root logger or not.
