scan:当此属性设置为true时，配置文件如果发生改变，将会被重新加载，默认值为true。
scanPeriod:设置监测配置文件是否有修改的时间间隔，如果没有给出时间单位，默认单位是毫秒。当scan为true时，此属性生效。默认的时间间隔为1分钟。
debug:当此属性设置为true时，将打印出logback内部日志信息，实时查看logback运行状态。默认值为false。

<div class="section"><div class="titlepage"><div><div><h4 class="title"><a id="logback.contextName"></a>31.5.5. contextName 设置上下文名称</h4></div></div></div>
<pre class="screen">
每个logger都关联到logger上下文，默认上下文名称为“default”。但可以使用设置成其他名字，用于区分不同应用程序的记录。设置后可以通过%contextName来打印日志上下文名称。
<contextName>logback</contextName>

用来定义变量值的标签， 有两个属性，name和value；其中name的值是变量的名称，value的值时变量定义的值。通过定义的值会被插入到logger上下文中。定义变量后，可以使“${}”来使用变量。

<pre class="screen">
<encoder>表示对日志进行编码：
%d{HH: mm:ss.SSS}——日志输出时间
%thread——输出日志的进程名字，这在Web应用以及异步任务处理中很有用
%-5level——日志级别，并且使用5个字符靠左对齐
%logger{36}——日志输出者的名字
%msg——日志消息
%n——平台的换行符

<pre class="screen">
上例中<fileNamePattern>${log.path}/logback.%d{yyyy-MM-dd}.log</fileNamePattern>定义了日志的切分方式——把每一天的日志归档到一个文件中，同理，可以使用%d{yyyy-MM-dd_HH-mm}来定义精确到分的日志切分方式。
<maxHistory>30</maxHistory>表示只保留最近30天的日志，以防止日志填满整个磁盘空间。
<totalSizeCap>1GB</totalSizeCap>用来指定日志文件的上限大小，例如设置为1GB的话，那么到了这个值，就会删除旧的日志。
