log4j 日志大小限制 分成30一个 不按日期分日志 按大小分成 按生产日期

首先说说生成按日期。不解释，大家都懂的，这种方法的缺点是很吃硬盘空间

log4j.rootLogger=INFO,logfile,stdout

log4j.logger.java.sql=DEBUG,sqllog
#log4j.additivity.java.sql=false
#velocity print out
log4j.logger.org.apache.velocity=ERROR,velocityfile
log4j.additivity.org.apache.velocity=false
log4j.logger.org.springframework.web.servlet.mvc.annotation=false
#app print out
log4j.logger.com.hundsun.network=DEBUG
log4j.logger.com.hundsun.network.melody.common.profiler=DEBUG,profiler
log4j.additivity.com.hundsun.network.melody.common.profiler=false

#standout log appender #
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n


#common log appender #
log4j.appender.logfile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.logfile.File=/WEB-INF/log/app.log
log4j.appender.logfile.append=true
log4j.appender.logfile.encoding=GB18030
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - %m%n

#error log appender #
log4j.appender.errorfile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.errorfile.File=/WEB-INF/log/error.log
log4j.appender.errorfile.Threshold=ERROR
log4j.appender.errorfile.append=true
log4j.appender.errorfile.encoding=GB18030
log4j.appender.errorfile.layout=org.apache.log4j.PatternLayout
log4j.appender.errorfile.layout.ConversionPattern=%d %p [%c] - %m%n

#sql log appender #
log4j.appender.sqllog=org.apache.log4j.DailyRollingFileAppender
log4j.appender.sqllog.File=/WEB-INF/log/sql.log
log4j.appender.sqllog.append=true
log4j.appender.sqllog.encoding=GB18030
log4j.appender.sqllog.layout=org.apache.log4j.PatternLayout
log4j.appender.sqllog.layout.ConversionPattern=%d %p [%c] - %m%n

#velocity log appender #
log4j.appender.velocityfile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.velocityfile.File=/WEB-INF/log/velocity.log
log4j.appender.velocityfile.append=true
log4j.appender.velocityfile.encoding=GB18030
log4j.appender.velocityfile.layout=org.apache.log4j.PatternLayout
log4j.appender.velocityfile.layout.ConversionPattern=%d %p [%c] - %m%n

#profile appender #
log4j.appender.profiler=org.apache.log4j.DailyRollingFileAppender
log4j.appender.profiler.File=/WEB-INF/log/profler.log
log4j.appender.profiler.append=true
log4j.appender.profiler.encoding=GB18030
log4j.appender.profiler.layout=org.apache.log4j.PatternLayout
log4j.appender.profiler.layout.ConversionPattern=%d %p [%c] - %m%n

于是我们来解决一下这个问题。把日志的大小限在10240Ｋ,一共仅仅许生成30个。循环覆盖
