<!-- 根节点<configuration>，包含下面三个属性： -->
<!-- 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。 -->
<configuration scan="true" scanPeriod="60 seconds" debug="false">
<!-- 子节点<contextName>：用来设置上下文名称，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<contextName>设置成其他名字，用于区分不同应用程序的记录。一旦设置，不能修改 -->
