当动态设置日志文件名时,RollingFileAppender与log4net.Appender.FileAppender MinimalLock锁定模型一起使用
似乎没有记录任何文件.但是,在没有此锁定模型的情况下使用appender时,日志记录有效.

在下面的配置文件中,Appender1可以工作,但Appender2不能：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,Log4net"/>
  </configSections>

  <log4net>
    <appender name="Appender2"
    type="log4net.Appender.RollingFileAppender" >
      <file type="log4net.Util.PatternString" value="%property{LogName}" />
      <encoding value="utf-8" />
      <appendToFile value="true" />
      <rollingStyle value="Size" />
      <maxSizeRollBackups value="10" />
      <maximumFileSize value="10000KB" />
      <staticLogFileName value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="[%logger] %message%n" />
      </layout>
      <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
    </appender>
    <appender name="Appender1"
    type="log4net.Appender.RollingFileAppender" >
      <file type="log4net.Util.PatternString" value="%property{LogName}" />
      <encoding value="utf-8" />
      <appendToFile value="true" />
      <rollingStyle value="Size" />
      <maxSizeRollBackups value="10" />
      <maximumFileSize value="10000KB" />
      <staticLogFileName value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%message%n" />
      </layout>
    </appender>
    <logger name="myLogger" additivity="false">
      <level value="DEBUG" />
      <appender-ref ref="Appender2" />
    </logger>
    <root>
      <level value="DEBUG" />
      <appender-ref ref="Appender1" />
    </root>
  </log4net>
</configuration>

这是我正在测试的示例代码：

static void Main(string[] args)
{
    ILog logger = LogManager.GetLogger("myLogger");
    GlobalContext.Properties["LogName"] = "Log1.log"; // <== The log file name is getting set here.  
    log4net.Config.XmlConfigurator.Configure(new FileInfo(@"Logger.config"));

    logger.Info("Sample log entry");
}

我做的另一个观察是,如果我删除根级别记录器,则记录似乎有效.

解决方法:

我想你必须添加

 <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />

对于两个appender,Appender1中都没有.这将解释为什么删除根元素有效.
