项目中不同日志打印在不同日志文件

1.在log4j.properties文件中添加

log4j.logger.ruiming=info,ruiming
log4j.additivity.ruiming=false
log4j.appender.ruiming=org.apache.log4j.DailyRollingFileAppender
log4j.appender.ruiming.DatePattern='_'yyyy-MM-dd-HH
log4j.appender.ruiming.File=/LOGS/logs/ruiming_gpsalarmdata.log
log4j.appender.ruiming.MaxFileSize=200M  
log4j.appender.ruiming.MaxBackupIndex=100
log4j.appender.ruiming.Append=true  
log4j.appender.ruiming.layout=org.apache.log4j.PatternLayout
log4j.appender.ruiming.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n

2.在类中

private static Logger ruiming = Logger.getLogger("ruiming");

ruiming.info(data);
