日誌級別基礎等級從高到低（並不是全部log實現都有以下級別）： OFF、 FATAL、ERROR、WARN、INFO、DEBUG、TRACE、ALLexpress

參考：app

一、簡介 LOGBack，一個「可靠、通用、快速而又靈活的Java日誌框架」。async

二、部署使用工具

在工程src目錄下創建logback.xml 注： 1.logback首先會試着查找logback.groovy文件; 2.當沒有找到時，繼續試着查找logback-test.xml文件; 3.當沒有找到時，繼續試着查找logback.xml文件; 4.若是仍然沒有找到，則使用默認配置（打印到控制檯）。性能

三、示例lua

<?xml version="1.0" encoding="UTF-8"?>

<!--
    configuration：
        scan:true設置加載配置，false不加載，defulat:true
        scanPeriod：掃描時間,默認1分鐘
        debug:是否打印logback內部日誌
 -->
<configuration scan="true" scanPeriod="60 seconds" debug="false">
    <!--
    property:屬性名稱 k-v格式
    contextName:每一個logger都關聯到logger上下文
    timestamp:時間戳,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" />

    <!--
        配置開啓 JMXConfigurator,經過jconsle等工具能夠查看配置
    -->
    <jmxConfigurator />

    <!--
    appender: name-引用名稱，class-類名 ch.qos.logback.core。*
        ConsoleAppender：控制檯
        FileAppender：文件
        RollingFileAppender：滾動

        filter：ThresholdFilter：臨界值過濾器，指定級別level
