public static void main(String[] args) {Logger logger = Logger.getLogger("userManager");logger.info("11111");Logger logger2 = Logger.getLogger("epic");logger2.error("2222");Logger logger3 = Logger.getLogger(Test.class);logger3.error("3333");}

每月产生一个文件：

log4j.appender.epicfile.DatePattern = '.'yyyy-MM-dd      log4j.appender.epicfile.DatePattern = '.'yyyy-MM

以文件大小备份：

#日志文件的大小 log4j.appender.epicfile.MaxFileSize=100KB # 保存一个备份文件 log4j.appender.epicfile.MaxBackupIndex=1
