	// config logback listener
	// 默认logback初始化会将初始化信息打印到控制台，但是可以通过设置listener的方式控制打印的位置
	// 目前有Nop，直接忽略，还可以将它放置在内存，后续拿出来，详细参考logback代码
	// use running command parameter
	// logback支持的listener启动参数
	// -Dlogback.statusListenerClass=ch.qos.logback.core.status.NopStatusListener
	// 或者在logback.xml中配置
/*
	<configuration>
  <statusListener class="ch.qos.logback.core.status.OnConsoleStatusListener" />  

  ... the rest of the configuration file  
</configuration>
