定义自己的Appender类，继承DailyRollingFileAppender，改写针对Threshold 的设置说明。

重写 isAsSevereAsThreshold(Priority priority)方法

 

package com.autonavi.tinfo.traffic.tmc.config;

import org.apache.log4j.Priority;
import org.apache.log4j.RollingFileAppender;

public class TMCRollingAppender extends RollingFileAppender {
    @Override  
     public boolean isAsSevereAsThreshold(Priority priority) {  
      //只判断是否相等，而不判断优先级  
      return this.getThreshold().equals(priority);  
     }
}
