log4j不同级别日志分不同文件记录

最近被问到一个log4j分不同文件记录不同级别日志的问题，一下给难倒了，以前没有留意过log4j的具体功能，只是了解了下。如今自己还差的远啊。╮(╯▽╰)╭。。。

参考了前段时间的那个项目中的log4j配置文件，发现那个只不过将不同模组的日志记录到不同的日志文件。并未按日志级别分文件记录。自己在动手调试的过程中结合查阅网上很多博文，终于以xml格式配置的方式调通。具体配置如下：

 

Xml代码

<?

 只不过是在配置appender的时候配置了一个LevelRangeFilter
的filter，并配置LevelMax与LevelMin(最大最小级别)，加个测试类：

 

Java代码

package
 com.javaeye.paopaohou;  

  

import
 org.apache.log4j.Logger;  

  

public
 
class
 TestLog4j {  

  

    private
 
static
 
final
 Logger log = Logger.getLogger(TestLog4j.
class
);  

    /**
 

     * 测试log4j不同级别日志分文件记录
 

     *
 

     */
  

  

    public
 
static
 
void
 main(String[] args) {  

        log.debug("debug..."
);  

        log.info("info..."
);  

        log.warn("warn..."
);  

        log.error("error..."
);  

  

    }  

  

}  

package com.javaeye.paopaohou;

import org.apache.log4j.Logger;

public class TestLog4j {

private static final Logger log = Logger.getLogger(TestLog4j.class);
/**
* 测试log4j不同级别日志分文件记录
*
*/

public static void main(String[] args) {
log.debug("debug...");
log.info("info...");
log.warn("warn...");
log.error("error...");

}

}

 这样就可以将不同级别的日志记录到不同的文件，可惜使用properties格式的log4j配置文件却没有调通。是因为properties格
式的文件不支持这么配置吗？不知道哪位在使用properties文件时候这么做过，还有我发现我经历的项目都使用xml格式的配置文件好像多于
properties格式的文件，是因为xml格式配置起来更灵活吗？学习。。。
