Log4j setting log level for individual class
提问by vico
I have package mypack and MyClass in this package. I would like to log just INFO level for this class and trying to set it using log4j.properties:
我在这个包中有包 mypack 和 MyClass 。我只想记录此类的 INFO 级别并尝试使用 log4j.properties 设置它：
log4j.debug=true
log4j.rootLogger=ALL, debugLogfile
log4j.rootCategory=, debugLogFile
#log4j.category.mypack =INFO
log4j.logger.mypack =INFO
log4j.appender.debugLogfile=org.apache.log4j.RollingFileAppender
log4j.appender.debugLogfile.File=mylog.log
log4j.appender.debugLogfile.Threshold=ALL
log4j.appender.debugLogfile.MaxFileSize=100MB
log4j.appender.debugLogfile.MaxBackupIndex=4
log4j.appender.debugLogfile.layout=org.apache.log4j.PatternLayout
log4j.appender.debugLogfile.layout.ConversionPattern=%d %-4r [%t] %-5p %c %x - %m%n
Unfortunately class logs DEBUG level also. What is wrong?
不幸的是，类也记录了 DEBUG 级别。怎么了？
I create logger in this way:
我以这种方式创建记录器：
public final Logger log = Logger.getLogger(getClass());

What you need is to set packageloggeraccess at Categoryor Loggerlevel, to achive this try following :
您需要packagelogger在Category或Logger级别设置访问权限，以实现此尝试，请执行以下操作：
# make default and debugLogFile both as root category
log4j.rootCategory=, debugLogFile
# set package wide logger Level (via Category, older way)
log4j.category.mypack=INFO
# OR set package wide logger Level (via Logger, newer way)
log4j.logger.mypack=INFO
# an example of turning all apache package logs to WARN
log4j.category.org.apache=WARN

Try
尝试
log4j.rootLogger=DEBUG, stdoutdebugLogfile
log4j.logger.mypack = INFO
log4j.rootLogger=DEBUG, stdoutdebugLogfile
log4j.logger.mypack = INFO
instead of
代替
log4j.appender.debugLogfile.mypack =INFO
log4j.appender.debugLogfile.mypack =INFO
To set DEBUG level for whole app and INFO for 'mypack' package.
为整个应用程序设置调试级别，为“mypack”包设置信息。

As far as i remember you can specify it like this
据我记得你可以像这样指定它
log4j.logger.com.proj.eqd.exo.http.filter=INFO
log4j.logger.com.proj.eqd.exo.http.filter=INFO

try adding this :
尝试添加这个：
log4j.logger.mypack =INFO, debugLogfile
log4j.additivity.mypack = false
log4j.rootLogger=ALL, debugLogfile
Your class is using the config for the rootLogger and also its own. By adding the additivity parameter, you will avoid it.
您的课程正在使用 rootLogger 的配置以及它自己的配置。通过添加可加性参数，您将避免它。
Hope it helps.
希望能帮助到你。
