I try write messages of my custom log level "BSHARING_LOG" to separate log file "bsharing.log". After start app, empty file 'bsharing.log' appears, but no messages in it. Both "test log message2" and "test log message" are on console. But not in file 'bsharing.log'. Messages for standart levels writes to 'application.log'. What's wrong?

我尝试将我的自定义日志级别“BSHARING_LOG”的消息写入单独的日志文件“bSharing.log”。启动应用程序后，会出现空文件‘bSharing.log’，但其中没有消息。“测试日志消息2”和“测试日志消息”都在控制台上。但不在文件‘bSharing.log’中。将标准级别的消息写入‘Applation.log’。怎么了？

}

If

如果

<Root level="info">
   <AppenderRef ref="Console" />
   <AppenderRef ref="appLog" />
   <AppenderRef ref="bsharingLogAppender" />
</Root>

then logs writes to both files.
I can't understand, why my custom log messages appears only in console, but not in file 'bsharing.log'.

然后记录对这两个文件的写入。我不明白，为什么我的自定义日志消息只出现在控制台中，而不出现在‘bSharing.log’文件中。
