不在web中使用的log方法

导入jar包：log4j-1.2.14.jar
package com.rsl.log;
import org.apache.log4j.Logger;
public class TestLog {
    public static void main(String args[]){
        Logger logger = Logger.getLogger(TestLog.class);
        logger.debug("debug");
        logger.info("info");
        logger.error("error");
    }

}

配置文件要放在src目录下：http://blog.csdn.net/Kawaboger/article/details/7357344#t5
