java - Apache Storm - log4j2 始终打印自己的日志，即使我关闭根记录器

Question

在我的 Storm APP 中，每次运行时我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:\Desarrollo\workspaces\oxygen_main\StormAcustat\target\classes\log4j2.xml]

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，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 消除它或log4j2配置。

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 的日志文件, org.apache.storm.kafka等等，不要包含这些行，并检查源代码，PluginManager {} found {} plugins在类里面看到:

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

它位于依赖项之一 log4j-core-2.8.2.jar 内.

所以，控制台似乎打印了来自 log4j 的日志，不是来自 Storm。

如何防止这种情况发生？正如您所看到的，我已经关闭了根记录器，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>

Answer 1

正在打印的日志为 log4j2因为您已启用debug log4j2 的级别日志记录。

要关闭此详细日志记录，请更改 status Configuration 的属性配置中的元素为 warn或error -

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

休息应保持不变。

Log4j2 documentation详细描述了此日志记录 -

From log4j-2.9 onward

From log4j-2.9 onward, log4j2 will print all internal logging to the console if system property log4j2.debug is defined (with any or no value).

Prior to log4j-2.9

Prior to log4j-2.9, there are two places where internal logging can be controlled:

If the configuration file is found correctly, log4j2 internal status logging can be controlled by setting <Configuration status="trace"> in the configuration file. This will display detailed log4j2-internal log statements on the console about what happens during the configuration process. This may be useful to trouble-shoot configuration issues. By default the status logger level is WARN, so you only see notifications when there is a problem.

If the configuration file is not found correctly, you can still enable log4j2 internal status logging by setting system property -Dorg.apache.logging.log4j.simplelog.StatusLogger.level=TRACE.
