测试类

package com.mark.other;

import org.junit.Test;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

/**
 * Created by Mark on 2018/3/27.
 * LogBack日志输出测试
 */
public class logBackTest {
    private static Logger logger = LoggerFactory.getLogger(logBackTest.class);

    @Test
    public  void testLog(){
        logger.debug("This is DeBug");
        logger.info("This is Info");
        logger.error("This is Error");
    }
}

输出结果：

这里输出的日志可以高亮显示是因为

 <property name="log.pattern" value="%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %highlight(%-5level)  %magenta(%logger{50}) - %msg%n" /><!--日志的输出格式-->

配置文件设置了%highlight 和 %magenta（详情或者更多的设置可以查看上面官网地址）
