Answer 1

给你个我用的：

log4j.rootCategory=INFO, stdout , R

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%t] %C.%M(%L) | %m%n

log4j.appender.R=org.apache.log4j.DailyRollingFileAppender
log4j.appender.R.File=./logs/Server.log
log4j.appender.R.DatePattern = '.'yyyy-MM-dd
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%d %p [%t] %C.%M(%L) | %m%n

log4j.logger.com.xxx=DEBUG
log4j.logger.controllers=DEBUG
log4j.logger.vo=DEBUG
log4j.logger.notifiers=DEBUG

log4j.logger.com.opensymphony.oscache=WARN
log4j.logger.net.sf.navigator=WARN
log4j.logger.org.apache.commons=WARN
log4j.logger.org.apache.struts=WARN
