如何按名稱空間對log4net中的日志消息進行分組？

Question

我正在嘗試實現自己的log4net附加程序，該附加程序將按名稱空間將消息分組。 問題是，我無法像我想要的那樣讓log4net記錄LocationInformation。

  class Program
{
    protected static IWindsorContainer container;
    static void Main(string[] args)
    {
        container = new WindsorContainer();
        container.Kernel.Resolver.AddSubResolver(new ArrayResolver(container.Kernel));

        // add facilities
        container.AddFacility("logging.facility", new LoggingFacility(LoggerImplementation.Log4net, "log4net.config"));
        container.Register(Component.For<ParentClass>().ImplementedBy<ParentClass>());
        container.Register(Component.For<ChildClass>().ImplementedBy<ChildClass>());                      

        var parentClass = container.Resolve<ParentClass>();
        var childClass = container.Resolve<ChildClass>();
        parentClass.Init();
        childClass.Init();

    }
}

public class ParentClass
{
    private readonly ILogger logger;

    private ILog localLogger;

    public ParentClass(ILogger logger)
    {
        this.logger = logger;
        localLogger = LogManager.GetLogger(GetType());
        logger.Info("ctor ioc logger, type: {0}",GetType().Name);
        localLogger.Info(string.Format("ctor local logger, type: {0}", GetType().Name));
    }

    public void Init()
    {
        logger.Info("init ioc logger, type: {0}", GetType().Name);
        localLogger.Info(string.Format("init local logger, type: {0}", GetType().Name));
    }
}

public class ChildClass : ParentClass
{
    public ChildClass(ILogger logger) : base(logger)
    {

    }
}

輸出是

2011-03-28 09:58:55 INFO 10 ParentClass - ctor ioc logger, type: ParentClass
2011-03-28 09:58:55 INFO 10 ParentClass - ctor local logger, type: ParentClass
2011-03-28 09:58:55 INFO 10 ParentClass - ctor ioc logger, type: ChildClass
2011-03-28 09:58:55 INFO 10 ParentClass - ctor local logger, type: ChildClass
2011-03-28 09:58:55 INFO 10 ParentClass - init ioc logger, type: ParentClass
2011-03-28 09:58:55 INFO 10 ParentClass - init local logger, type: ParentClass
2011-03-28 09:58:55 INFO 10 ParentClass - init ioc logger, type: ChildClass
2011-03-28 09:58:55 INFO 10 ParentClass - init local logger, type: ChildClass

問題是，log4net類名稱始終輸出為基類名稱（ParentClass）。 我最初以為可能是溫莎城堡，導致了這種問題，但結果表明，即使我手動創建了記錄器實例，它仍然記錄基類名稱。 可能有人知道，如何強制log4net寫入實際實例類名？

更新

這是使用的log4net配置：

<appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
  <file value="c:\temp\testlog.log" />
  <appendToFile value="true" />
  <maximumFileSize value="10MB" />
  <maxSizeRollBackups value="2" />

  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%utcdate{yyyy-MM-dd HH:mm:ss} %level %thread %C{1} - %message%newline" />
  </layout>
</appender>

<root>
  <level value="INFO" />
  <appender-ref ref="RollingFile" />      
</root>

上面的輸出是我得到的，我期望得到的是：

2011-03-28 09:58:55 INFO 10 ParentClass - ctor ioc logger, type: ParentClass
2011-03-28 09:58:55 INFO 10 ParentClass - ctor local logger, type: ParentClass
2011-03-28 09:58:55 INFO 10 ChildClass - ctor ioc logger, type: ChildClass
2011-03-28 09:58:55 INFO 10 ChildClass - ctor local logger, type: ChildClass
2011-03-28 09:58:55 INFO 10 ParentClass - init ioc logger, type: ParentClass
2011-03-28 09:58:55 INFO 10 ParentClass - init local logger, type: ParentClass
2011-03-28 09:58:55 INFO 10 ChildClass - init ioc logger, type: ChildClass
2011-03-28 09:58:55 INFO 10 ChildClass - init local logger, type: ChildClass

萬一有人需要這種東西，這里是可行的追加器實現：

public class GroupStringListAppender : log4net.Appender.AppenderSkeleton
{
    private readonly int listLength = 30;
    private readonly Func<string, string> pathFuction;
    private readonly Dictionary<string, List<string>> messagesDictionary = new Dictionary<string, List<string>>();

    public GroupStringListAppender(int listLength, Func<string, string> pathFuction)
    {
        this.listLength = listLength;
        this.pathFuction = pathFuction;
    }

    public List<string> GetMessages(string path)
    {
        return messagesDictionary[path];
    }        

    protected override void Append(LoggingEvent loggingEvent)
    {
        var msg = loggingEvent.RenderedMessage;
        var path = pathFuction.Invoke(loggingEvent.LoggerName);

        if (!messagesDictionary.ContainsKey(path))
        {
            messagesDictionary.Add(path, new List<string>());
            OnNewPathCreated(path);
        }

        var list = messagesDictionary[path];        

        while (list.Count - listLength > 0)
        {
            list.RemoveAt(0);    
        }

        list.Add(msg);

        OnAppended(path, list);          
    }

    public event AppendedEventHandler Appended;

    public void OnAppended(string path, List<string> list)
    {
        AppendedEventHandler handler = Appended;
        if (handler != null) handler(this, new LoggerMessageAppendedEventArgs(path, list));
    }

    public event NewPathCreatedHandler NewPathCreated;

    public void OnNewPathCreated(string path)
    {
        var handler = NewPathCreated;
        if (handler != null) handler(this, new NewPathCreatedHandlerArgs(path));
    }
}

public delegate void NewPathCreatedHandler(object sender, NewPathCreatedHandlerArgs args);

public class NewPathCreatedHandlerArgs : EventArgs
{
    public string Path { get; set; }

    public NewPathCreatedHandlerArgs(string path)
    {
        Path = path;
    }
}

public class LoggerMessageAppendedEventArgs : EventArgs
{
    public string Path { get; set; }
    public List<string> List { get; set; }

    public LoggerMessageAppendedEventArgs(string path, List<string> list)
    {
        Path = path;
        List = list;
    }
}

public delegate void AppendedEventHandler(object sender, LoggerMessageAppendedEventArgs e);

通過使用%logger而不是%C{1}您至少將獲得本地記錄器所需的結果。

我認為對於IoC，您需要做更多的事情。 必須對此進行更多調查...
