Apache Storm - log4j2一直在打印自己的日志，即使我关闭了根记录器

Question

在我的 Storm 应用程序中，每次运行时，我现在都会从控制台获取这些行：

2018-01-17 18:38:30,417 main DEBUG Initializing configuration XmlConfiguration[location=D:Desarrolloworkspacesoxygen_mainStormAcustattargetclasseslog4j2.xml]

2018-01-17 18:38:31,284 main DEBUG Starting OutputStreamManager SYSTEM_OUT.false.false

我已经配置了log4j2.xml，使 Storm 将其日志重定向到不同的日志文件中，并且它正在工作：

<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。我想用log4j或log4j2配置来消除它。

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等的日志文件不包含这些行，并检查源代码，PluginManager {} found {} plugins在类中看到：

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

它位于依赖项之一中，log4j-core-2.8.2.jar.

因此，控制台似乎打印了log4j的日志，而不是来自 Storm。

如何预防？如您所见，我已经关闭了根记录器，并且有以下行，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：

Answer 1

正在打印的日志是log4j2的，因为您已启用debuglog4j2的日志记录。

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

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

其余部分应保持不变。

Log4j2 文档详细描述了此日志记录 -

从log4j-2.9开始

从 log4j-2.9 开始，log4j2 会将所有内部日志记录打印到 控制台(如果定义了系统属性log4j2.debug(使用任何或否) 值)。

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：

如果正确找到配置文件，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。这将显示详细的日志4j2-内部日志 控制台上关于配置期间发生的情况的语句 过程。这对于解决配置问题可能很有用。由 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。

如果未正确找到配置文件，您仍然可以启用 通过设置系统属性记录 log4j2 内部状态-Dorg.apache.logging.log4j.simplelog.StatusLogger.level=TRACE.
