Log4j2在apender中过滤特定级别 [英] Log4j2 Filter particular level in apender
本文介绍了Log4j2在apender中过滤特定级别的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我应该使用什么过滤器来定义要使用apender记录的特定级别?例如:
What filter should i use, to define particular level to be logged with apender? For example:
java:
LOGGER.debug("Debug message");
LOGGER.info("Info message");
LOGGER.warn("Warn message");
LOGGER.error("Error message");
LOGGER.fatal("Fatal message");
log4j2.xml:
log4j2.xml:
<Configuration>
<Appenders>
<Console name="info-stdout-message">
<PatternLayout pattern="[%logger{36}] %message %n" />
<ThresholdFilter level="info"/>
</Console>
<Console name="detailed-stdout-message">
<PatternLayout pattern="[%logger{36}] [%level] %message %n" />
</Console>
<File name="file-appender" fileName="logs/debug.log">
<PatternLayout pattern="%d{HH:mm:ss dd.mm} [%t] [%-5level] %logger{36} - %msg %n" />
</File>
</Appenders>
<Loggers>
<Root level="debug">
<AppenderRef ref="file-appender" level="debug" />
<AppenderRef ref="info-stdout-message" level="info"/>
<AppenderRef ref="detailed-stdout-message" level="info"/>
</Root>
</Loggers>
</Configuration>
文件输出正常,但在控制台我有这样的结果:
The file output is fine, but in console I have such result:
[application.Main] [INFO] Info message
[application.Main] Info message
[application.Main] [WARN] Warn message
[application.Main] Warn message
[application.Main] [ERROR] Error message
[application.Main] Error message
[application.Main] [FATAL] Fatal message
[application.Main] Fatal message
但我需要 info-stdout-message
appender只输出INFO消息,而 detailed-stdout-message
输出所有EXEPT INFO。因此控制台输出应如下所示:
but I need info-stdout-message
appender to output only INFO messages, while detailed-stdout-message
to output all EXEPT INFO. So the console output should looks like:
[application.Main] Info message
[application.Main] [WARN] Warn message
[application.Main] [ERROR] Error message
[application.Main] [FATAL] Fatal message
无法了解如何防止过滤器尊重级别继承。是否可以这样做?
Can't find out how to prevent filters respect level inheritance. Is it possible to do this?
推荐答案
这有效:
<Console name="info-stdout-message">
<PatternLayout pattern="[%logger{36}] %message %n" />
<Filters>
<!-- Now deny warn, error and fatal messages -->
<ThresholdFilter level="warn" onMatch="DENY" onMismatch="NEUTRAL"/>
<!-- This filter accepts info, warn, error, fatal and denies debug/trace -->
<ThresholdFilter level="info" onMatch="ACCEPT" onMismatch="DENY"/>
</Filters>
</Console>
