log4j 按照要求打到不同的日志

关键点  配置文件

log4j.rootLogger = info,stdout
log4j.logger.com.smartshown.mylog.mylog = info,adups
log4j.additivity.com.smartshown.mylog.mylog = false
log4j.logger.com.smartshown.mylog.userlog= info,userlog
log4j.additivity.com.smartshown.mylog.userlog = false
log4j.logger.com.ibatis = info,ibatis
log4j.logger.java.sql = debug,ibatis
#log = /home/yang/logs/
log =E:/logs
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %C{1}:%L - %m%n


log4j.appender.adups = org.apache.log4j.DailyRollingFileAppender
log4j.appender.adups.File = ${log}/smart
log4j.appender.adups.DatePattern='_'yyyyMMdd'.log'
log4j.appender.adups.layout = org.apache.log4j.PatternLayout
log4j.appender.adups.layout.ConversionPattern = %d{yyyy-MM-dd HH:mm:ss} %C{1}:%L - %m%n
log4j.appender.adups.Append=true


log4j.appender.userlog = org.apache.log4j.DailyRollingFileAppender
log4j.appender.userlog.File = ${log}/userlog
log4j.appender.userlog.DatePattern='_'yyyyMMdd'.log'
log4j.appender.userlog.layout = org.apache.log4j.PatternLayout
log4j.appender.userlog.layout.ConversionPattern = %d{yyyy-MM-dd HH:mm:ss} %C{1}:%L - %m%n
log4j.appender.userlog.Append=true


log4j.appender.ibatis = org.apache.log4j.DailyRollingFileAppender
log4j.appender.ibatis.File = ${log}/ibatis
log4j.appender.ibatis.DatePattern='_'yyyyMMdd'.log'
log4j.appender.ibatis.layout=org.apache.log4j.PatternLayout
log4j.appender.ibatis.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %C{1}:%L - %m%n
log4j.appender.ibatis.Append=true




mylog和userlog是两个不同的log类 

package com.smartshown.mylog;




import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;




/**
 * 日志配置类
 */
public class mylog {

private static Log logger;
 private static boolean DBUG = true;


 public static void log(String tag, String content) {
   if (DBUG)
     getLogger().info(tag + ": " + content);
 }


 private static Log getLogger()
 {
   if (logger == null) {
     logger = LogFactory.getLog(mylog.class);
   }


   return logger;
 }


}

在用的地方只需要

mylog.log("111", "222");
userlog.log("rrr1232", "wwwww");

就会打到不同的文件中。
