如何在 log4net 中记录没有路径的类文件

发布于 2024-07-30 05:01:41 字数 690 浏览 3 评论 0原文

我希望能够在日志文件中记录类文件和行号，因此我使用以下配置...

<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
  <!--etc-->
   <layout type="log4net.Layout.PatternLayout">
       <conversionPattern value="%date [%thread] %-5level (%file:%line) %logger => %message%newline" />
  </layout>
</appender>

但是 %file 属性使我的日志文件条目太长而无法舒适地阅读...

2009-08-07 16:41:55,271 [7] INFO  (O:\mystream\aevpallsrv\DotNet\com.mycompany.au\myapp\Myappp\Controller.cs:75) MyApp.Controller => Controller.EnqueueWorkerThreads() - START

有吗一种只显示类文件（'Controller.cs'）而不是文件的完整路径的方法？？？

I want to be able to log the class file and line number in my log file so I am using the following config...

<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
  <!--etc-->
   <layout type="log4net.Layout.PatternLayout">
       <conversionPattern value="%date [%thread] %-5level (%file:%line) %logger => %message%newline" />
  </layout>
</appender>

However the %file attribute is making my log file entries waaaay too long to read comfortably....

2009-08-07 16:41:55,271 [7] INFO  (O:\mystream\aevpallsrv\DotNet\com.mycompany.au\myapp\Myappp\Controller.cs:75) MyApp.Controller => Controller.EnqueueWorkerThreads() - START

Is there a way to show just the class file ('Controller.cs') instead of the full path to the file also???

尽管您询问的是文件名，但我相信您可以使用 %type 来获取完全限定的类型名称 (abclassName)。如果您只需要类名，请使用 %type{1}

请注意，任何生成调用者信息（%file 和 %type）的方法都会产生与之相关的性能成本。

顺便说一句，您可以通过使用类型名称命名记录器来绕过性能影响。

namespace MyNamespace
{     
    public class Foo
    {
        private static ILog log = LogManager.GetLogger(typeof(Foo));
    }
}

您的转换模式将如下所示：

"%date [%thread] %-5level %logger %message"

您的记录器将是“MyNameSpace.Foo”。同样，如果您只需要类名，请使用“%logger{1}”，它将解析为“Foo”。

这种方法的最大优点之一是您可以利用 log4net 的分层存储库系统来调整每种类型的日志记录级别：

<!-- all classes in MyNamespace are warn -->
<logger name="MyNamespace">
     <level value="WARN" />
</logger>

<!-- only Foo is in debug -->
<logger name="MyNamespace.Foo">
    <level value="DEBUG" />
</logger>

Although you're asking about the file name, I believe you can use %type to get the fully qualified type name (a.b.className). If you just want the class name, use %type{1}

Note that any method that generates caller information (%file and %type) have a performance cost associated with them.

As an aside, you can bypass the performance hit by naming the Logger using the Type name.

namespace MyNamespace
{     
    public class Foo
    {
        private static ILog log = LogManager.GetLogger(typeof(Foo));
    }
}

Your conversion pattern would look like:

"%date [%thread] %-5level %logger %message"

Where your logger would be "MyNameSpace.Foo". Likewise, if you only want the class name, use "%logger{1}, which will resolve as "Foo".

One of the best advantages to this approach is that you can leverage log4net's hierarchical repository system to adjust logging levels per type:

<!-- all classes in MyNamespace are warn -->
<logger name="MyNamespace">
     <level value="WARN" />
</logger>

<!-- only Foo is in debug -->
<logger name="MyNamespace.Foo">
    <level value="DEBUG" />
</logger>
