log4j category
提问by Nuno Furtado
I have the following on my log4j.properties
我的 log4j.properties 上有以下内容
log4j.rootLogger = debug, stdout, fileLog
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.fileLog = org.apache.log4j.RollingFileAppender
log4j.appender.fileLog.File = C:/logs/services.log
log4j.appender.fileLog.MaxFileSize = 256MB
log4j.appender.fileLog.MaxBackupIndex = 32
#Category: ConsultaDados
log4j.category.ConsultaDados=ConsultaDados
log4j.appender.ConsultaDados=org.apache.log4j.DailyRollingFileAppender
log4j.appender.ConsultaDados.layout=org.apache.log4j.PatternLayout
log4j.appender.ConsultaDados.layout.ConversionPattern={%t} %d - [%p] %c: %m %n
log4j.appender.ConsultaDados.file=C:/logs/consulta.log
log4j.appender.ConsultaDados.DatePattern='.' yyyy-MM-dd-HH-mm
And im creating my logger with :
我用以下方法创建我的记录器：
myLogger = Logger.getLogger("ConsultaDados");
But this doesnt log my calls to the file. they get thrown into the rootLogger
但这不会记录我对文件的调用。他们被扔进了 rootLogger
Any ideas?
有任何想法吗？

Just to finish this thread, the real issue was that the first value on your category line should have been a log level. So, as you correctly discovered, changing :
为了完成这个线程，真正的问题是类别行上的第一个值应该是日志级别。因此，正如您正确发现的那样，更改：
log4j.category.ConsultaDados=ConsultaDados
log4j.category.ConsultaDados=ConsultaDados
to
到
log4j.category.ConsultaDados=info,ConsultaDados
log4j.category.ConsultaDados=info,ConsultaDados
worked properly. As an FYI, you could have also changed the line to
工作正常。作为仅供参考，您也可以将行更改为
log4j.category.ConsultaDados=,ConsultaDados
log4j.category.ConsultaDados=,ConsultaDados
which would have caused you to inherit the logging level from the root logger.
这会导致您从根记录器继承日志记录级别。

First, your category is not mapped to an appender, second ConsultaDadosEORIdoesn't match any category.
首先，您的类别未映射到附加程序，第二个ConsultaDadosEORI不匹配任何类别。
Here is a sample :
这是一个示例：
log4j.appender.YOUR_APPENDER=org.apache.log4j.RollingFileAppender
log4j.appender.YOUR_APPENDER.File=${SYSTEM_PROPEY_WITH_LOGGER_FOLDER}/log_file.log
log4j.appender.YOUR_APPENDER.Append=true
log4j.appender.YOUR_APPENDER.MaxFileSize=20MB
log4j.appender.YOUR_APPENDER.MaxBackupIndex=2
log4j.appender.YOUR_APPENDER.layout=org.apache.log4j.PatternLayout
log4j.appender.YOUR_APPENDER.layout.ConversionPattern=%d [%t] %p %c - %m %n
log4j.category.**YOUR_PACKAGE**=**INFO,YOUR_APPENDER**
log4j.additivity.**YOUR_PACKAGE**=true or false
