日志级别基础等级从高到低（并不是全部log实现都有以下级别）： OFF、 FATAL、ERROR、WARN、INFO、DEBUG、TRACE、ALLexpress

一、简介 LOGBack，一个“可靠、通用、快速而又灵活的Java日志框架”。async
二、部署使用工具
在工程src目录下创建logback.xml 注： 1.logback首先会试着查找logback.groovy文件; 2.当没有找到时，继续试着查找logback-test.xml文件; 3.当没有找到时，继续试着查找logback.xml文件; 4.若是仍然没有找到，则使用默认配置（打印到控制台）。性能
三、示例lua
<?xml version="1.0" encoding="UTF-8"?>

<!--
    configuration：
        scan:true设置加载配置，false不加载，defulat:true
        scanPeriod：扫描时间,默认1分钟
        debug:是否打印logback内部日志
 -->
<configuration scan="true" scanPeriod="60 seconds" debug="false">
    <!--
    property:属性名称 k-v格式
    contextName:每一个logger都关联到logger上下文
    timestamp:时间戳,datePattern 格式
    -->
    <property name="APP_NAME" value="walter" />
    <contextName>${APP_NAME}</contextName>
    <timestamp key="time" datePattern="yyyyMMdd'T'HHmmss"/>
    <property name="LOG_HOME" value="F:/project/logback" />

    <!--
        配置开启 JMXConfigurator,经过jconsle等工具能够查看配置
    -->
    <jmxConfigurator />

    <!--
    appender: name-引用名称，class-类名 ch.qos.logback.core。*
        ConsoleAppender：控制台
        FileAppender：文件
        RollingFileAppender：滚动

            rollingPolicy：滚动策略，TimeBasedRollingPolicy-最经常使用按照时间
            maxHistory：控制保留的归档文件的最大数量
            timeBasedFileNamingAndTriggeringPolicy：maxFileSize最大文件
        filter：ThresholdFilter：临界值过滤器，指定级别level
