Question

我的根记录器捕获除off之外的所有级别的日志。我的等级设为INFO。我搜索了某个地方的等级是否有所改变，但我一无所获。

当我将记录器IBatisNet.DataMapper.Commands.DefaultPreparedCommand放到DEBUG时，日志将在SpecificAppender的文本文件中创建。但是，即使根设置为INFO，日志也会出现在控制台中。

这是我的代码：

我尝试将root的级别更改为其他级别，但我总是得到相同的结果。

这似乎是log4net的工作方式。处理配置文件时，其行为就像配置如下：

<logger name="IBatisNet.DataMapper.Commands.DefaultPreparedCommand" additivity="false">
    <level value="DEBUG" />
    <appender-ref ref="SpecificAppender"/>
    <appender-ref ref="ConsoleAppender" />
    <appender-ref ref="LogBufferingAppender" />
</logger>

幸运的是，有一种解决方法，那就是在appender上设置一个级别过滤器，例如：对于ConsoleAppender：

 <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
  <layout type="log4net.Layout.PatternLayout">
    <param name="ConversionPattern" value="%d{HH:mm:ss,fff} [%t] %-5p %c{1} - %m%n" />
  </layout>
  <filter type="log4net.Filter.LevelRangeFilter">
    <levelMin value="INFO" />
    <acceptOnMatch value="true" />
  </filter>    
</appender>

将appender重命名为更具描述性的内容（如InfoConsoleAppender）也可能更好。此外，如果您希望能够在调试级别将某些记录器记录到控制台，那么您可能需要另一个未经过筛选的ConsoleAppender。

根日志所有级别
