Question

在我的Storm APP中，每次我跑步时，我都会从控制台获取这些线路：

我已配置log4j2.xml以使Storm将其日志重定向到不同的日志文件中，并且它正在运行：

<Loggers>
        <Logger name="org.apache.storm" level="debug" additivity="false">
            <AppenderRef ref="Storm"/>
        </Logger>
        <Logger name="org.apache.storm.kafka" level="debug" additivity="false">
            <AppenderRef ref="Storm-Kafka"/>
        </Logger>
        <Logger name="org.apache.zookeeper" level="debug" additivity="false">
            <AppenderRef ref="ZooKeeper"/>
        </Logger>
        <Logger name="org.apache.storm.shade.org.apache.zookeeper" level="debug" additivity="false">
            <AppenderRef ref="Storm-ZooKeeper"/>
        </Logger>
        <Logger name="TestMain" level="info">
            <AppenderRef ref="TestMain"/>
        </Logger>
        <!-- these lines don't work -->
        <Logger name="org.apache.logging.log4j" level="info">
            <AppenderRef ref="Storm-logging"/> 
        </Logger>
        <Root level="OFF">
            <AppenderRef ref="Console" />
        </Root>
    </Loggers>

但我仍然从控制台获取这些日志。我希望使用log4j或log4j2配置消除它。

我检查了日志，发现这些日志似乎来自org.apache.logging.log4j本身，而不是来自任何其他Storm类，因为org.apache.storm，org.apache.storm.kafka等日志文件在，不包括这些行，并检查源代码，在类中可以看到PluginManager {} found {} plugins：

org.apache.logging.log4j.core.config.plugins.util.PluginManager.class

它位于其中一个依赖项log4j-core-2.8.2.jar。

中

所以，似乎控制台打印的是来自log4j的日志，而不是来自Storm。

如何预防？正如你所看到的，我已经关闭了root logger并且我有这些行，但它们不起作用：

<Logger name="org.apache.logging.log4j" level="info">
    <AppenderRef ref="Storm-logging"/> 
</Logger>

编辑：我的log4j2.xml：

要打印的日志属于log4j2，因为您已启用debug级log4j2级日志记录。

要关闭此详细日志记录，请将配置中status元素的Configuration属性更改为warn或error -

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

休息应保持不变。

Log4j2 documentation详细介绍了此日志记录 -

从log4j-2.9开始

从log4j-2.9开始，log4j2将打印所有内部日志记录到   控制台，如果定义了系统属性log4j2.debug（任何或没有   值）。

在log4j-2.9之前

在log4j-2.9之前，有两个地方可以进行内部日志记录   控制：

如果找到配置文件正确，则log4j2内部状态   可以通过设置<Configuration status="trace">来控制日志记录   配置文件。这将显示详细的log4j2内部日志   控制台上有关配置期间发生的情况的语句   处理。这可能有助于解决配置问题。通过   默认情况下，状态记录器级别为WARN，因此您只能看到通知   当出现问题时。

如果找不到配置文件，您仍然可以启用   通过设置系统属性来记录log4j2内部状态   -Dorg.apache.logging.log4j.simplelog.StatusLogger.level=TRACE。

Apache Storm - 即使我关闭root logger，log4j2也会一直打印自己的日志
