Log4j配置

　　1、导入Log4j的jar包；

　　2、配置Log4j.properties:

#log4j.rootCategory=error,stdout
#
#log4j.appender.stdout=org.apache.log4j.ConsoleAppender
#log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
#log4j.appender.stdout.layout.ConversionPattern=[HYYT] %p [%t] %C.%M(%L) | %m%n
#
#log4j.logger.com.opensymphony.xwork2.ognl.OgnlValueStack=ERROR

　　3、编写测试类：

public class LoggerTest {
    
    private static final Logger logger = Logger.getLogger(LoggerTest.class);


    @Test
    public void sysLog(){
        System.out.println("-------------------\n" + "sys日志" + "\n-------------------");
        logger.debug("-------------------\n" + "Debug日志" + "\n-------------------");//不打印
        logger.info("-------------------\n" + "Info日志" + "\n-------------------");
        logger.warn("-------------------\n" + "Warn日志" + "\n-------------------");
        logger.error("-------------------\n" + "Error日志" + "\n-------------------");
    }
    
}

　　4、生成的日志文件：
