[log4j2_2.1] How to write different log-messages to different log-files?

[joey . lv]

I want to write the 'trace' and 'debug' messages to debug.log, 'info' messages 
to info.log, and 'warn','error','fafal' messages to error.log

Here is a sample java code,
package com.r7oad.udsp.common.cache.test;

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

public class Log4j2Test {
    private static final Logger logger = LogManager.getLogger(Log4j2Test.class);
    public static void main(String[] args){
        logger.trace("Hello world - trace log");
        logger.debug("Hello world - debug log");
        logger.info("Hello world - info log");
        logger.warn("Hello world - warn log");
        logger.error("Hello world - error log");
        logger.fatal("Hello world - fatal log");
    }
}

messages in debug.log file. (correct)

so, how to config the <ThresholdFilter/> to achieve my purpose?
