Java 停止日志4J2记录器初始化日志打印到标准输出

下面是log4j2.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="DEBUG">
  <Properties>
    <Property name="log-path">C:/logs</Property>
  </Properties>
  <Appenders>
    <RollingFile name="RollingFile" fileName="${log-path}/myexample.log"
         filePattern="${log-path}/myexample-%d{yyyy-MM-dd}-%i.log" >
      <PatternLayout>
    <pattern>%d{dd/MMM/yyyy HH:mm:ss,SSS}- %c{1}: %m%n</pattern>
      </PatternLayout>
      <Policies>
    <SizeBasedTriggeringPolicy size="1 KB" />
      </Policies>
      <DefaultRolloverStrategy max="4"/>
    </RollingFile>
  </Appenders>
  <Loggers>
    <Logger name="root" level="debug" additivity="false">
      <appender-ref ref="RollingFile" level="debug"/>
    </Logger>
  </Loggers>
</Configuration>

为什么会打印这些初始化语句？

在配置的第一行将状态记录器级别从调试更改为警告

塔克斯。顺便问一下，是否可以将配置输出设置为其他文件记录器？
