一、log4g简单配置控制台配置


以下是对log4j.properties文件配置====

log4j.properties


以下是Test.java文件========

package com.sec.log4j;
import org.apache.log4j.Logger;
public class Test{

    private static final Logger logger = Logger.getLogger(Test.class);
    public static void main(String[] args){
        for(int i=0;i<1000;i++){
            logger.debug("1111");
        }
    }
}

以下是TestLog4j.java文件======

package com.sec.log4j;
import org.apache.log4j.Logger;
public class TestLog4j{
    private static Logger logger=Logger.getRootLogger();
    public static void main(String[] args){
        logger.debug("debug11");
        logger.info("info11");
        logger.warn("warn11");
        logger.error("error111");
    }
}
