I have multiple appenders in my log4j
config, and I was wondering whether it would be possible to define the layout and conversion pattern once for all of them.
I.e. I have
log4j.appender.CA=org.apache.log4j.ConsoleAppender
log4j.appender.CA.layout=org.apache.log4j.PatternLayout
log4j.appender.CA.layout.ConversionPattern=%d{yyyy/MM/dd HH:mm:ss} %-5p %c %x - %m%n
log4j.appender.FA=org.apache.log4j.RollingFileAppender
log4j.appender.FA.MaxBackupIndex=0
log4j.appender.FA.MaxFileSize=100Mb
log4j.appender.FA.File=log/my.log
log4j.appender.FA.layout=org.apache.log4j.PatternLayout
log4j.appender.FA.layout.ConversionPattern=%d{yyyy/MM/dd HH:mm:ss} %-5p %c %x - %m%n
and I'd like to know if and how I could define the last two rows of each appender's config only once.
Not sure if it is exactly what you want, but using the following you can define the layout in 1 place:
PATTERN = %-4r [%t] %-5p %c %x - %m%n
log4j.rootLogger=info, A
log4j.logger.FILE = info, FILE
log4j.appender.A=org.apache.log4j.ConsoleAppender
log4j.appender.A.layout=org.apache.log4j.PatternLayout
log4j.appender.A.layout.ConversionPattern=${PATTERN}
log4j.appender.FILE=org.apache.log4j.RollingFileAppender
log4j.appender.FILE.File=log.log
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.ConversionPattern=${PATTERN}
