<Configuration><!--Configuration有两个属性:status和monitorinterval-->
<!--Configuration后面的status，这个用于设置log4j2自身内部的信息输出，可以不设置，当设置成trace时，你会看到log4j2内部各种详细输出-->

<!--monitorInterval：Log4j能够自动检测修改配置 文件和重新配置本身，设置间隔秒数-->

<!--<configuration status="WARN" monitorInterval="30"> -->

    <Appenders><!--有“输出目的地”之意。（题外话：Appender和LogEvent都是log4j2的重要组件）Log4j2为使用者提供了13种非常实用的Appenders，使用者可用方便的调用这13种Appender来控制日志的输出
Appenders节点，常见的有三种子节点:Console、RollingFile、File.-->
        
        <!--Console节点用来定义输出到控制台的Appender.
            name:指定Appender的名字.
            target:SYSTEM_OUT 或 SYSTEM_ERR,一般只设置默认:SYSTEM_OUT.
            PatternLayout:输出格式，不设置默认为:%m%n.-->
        <Console name="STDOUT-APPENDER" target="SYSTEM_OUT">
            <PatternLayout pattern="%-5p %c{2} - %m%n%throwable" charset="UTF-8"/>
        </Console>
        <Console name="STDERR-APPENDER" target="SYSTEM_ERR">
            <PatternLayout pattern="%-5p %c{2} - %m%n%throwable" charset="UTF-8"/>
        </Console>
        
        <!--RollingFile节点用来定义超过指定大小自动删除旧的创建新的的Appender.
            name:指定Appender的名字.
            fileName:指定输出日志的目的文件带全路径的文件名.
            PatternLayout:输出格式，不设置默认为:%m%n.
            filePattern:指定新建日志文件的名称格式.
            Policies:指定滚动日志的策略，就是什么时候进行新建日志文件输出日志.
            TimeBasedTriggeringPolicy:Policies子节点，基于时间的滚动策略，interval属性用来指定多久滚动一次，默认是1 hour。modulate=true用来调整时间：比如现在是早上3am，interval是4，那么第一次滚动是在4am，接着是8am，12am...而不是7am.
            SizeBasedTriggeringPolicy:Policies子节点，基于指定文件大小的滚动策略，size属性用来定义每个日志文件的大小.
            DefaultRolloverStrategy:用来指定同一个文件夹下最多有几个日志文件时开始删除最旧的，创建新的(通过max属性)。
            append，boolean，指定是否是追加写入（append=true，默认情况），还是覆盖写入（append=false）-->
