单个 Logger 的每个 appender 的日志级别 [英] Log Level per appender for a single Logger

问题描述

是否可以根据 appender 为单个 Logger 配置不同的日志级别?

Is it possible to configure different log levels for a single Logger based on the appender?

我意识到这与此类似 问题，这是我自己已经知道的，但问题在于阈值适用于所有记录到该附加程序的记录器，而我只想要适用于单个记录器的阈值.

I realize this is similar to this question, and this is as far as I had already got myself, but the problem with this is that the threshold applies to all loggers that log to that appender, whereas I only want the threshold to apply to a single logger.

即到目前为止，我有这样的事情:

i.e. So far I have something like this:

log4j.rootLogger=WARN, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Threshold=WARN
log4j.appender.stdout.layout=org.apache.log4j.SimpleLayout

log4j.logger.mylogger=DEBUG,logfile
log4j.appender.logfile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.logfile.DatePattern=${roll.pattern.daily}
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%d{${datestamp}} [%t] %-5p %C{2} - %m%n
log4j.appender.logfile.File=mylogfile.log

我希望将 mylogger DEBUG 消息发送到 logfile 附加程序，但我也希望将 mylogger INFO 消息发送到 stdout 附加程序(但对于所有其他记录器，只有 WARN ings).使用阈值将 stdout 限制为 WARN 会限制 mylogger 的输出.

I want mylogger DEBUG messages to be send to the logfile appender, but I also want mylogger INFO messages to be sent to the stdout appender (but for all other loggers only WARN ings). Using the Threshold to limit stdout to WARN restricts the output of mylogger.

推荐答案

啊哈，我改了

log4j.appender.stdout.Threshold=WARN

到

log4j.appender.stdout.Threshold=INFO

第一次应该更加小心.
