ServiceStack 4.5以编程方式配置log4net [英] ServiceStack 4.5 configure log4net programmatically

问题描述

我正在使用ServiceStack 4.5启动一个新项目.有什么方法可以通过编程方式配置log4net?在我找到的文档中

I am starting a new project with ServiceStack 4.5. Is there any way to configure log4net programmatically? In the documentation I found

LogManager.LogFactory = new Log4NetFactory(configureLog4Net: true); 

我将其添加到AppHost类的构造函数中.但是，这似乎是假设您将配置放入App.config文件中(我正在Windows服务上进行自我托管).

I added this to the constructor of the AppHost class. However this seems to assume that you put the configuration to the App.config file (I am doing self-hosting on a windows service).

在其他一些项目中，我编写了一个单例，然后使用Log4Net API进行配置:

In some other projects I wrote a singleton and then used the Log4Net API to do the configuration:

   private static void CreateFileAppender(ref Logger bedInventoryLogger, string logFilePath, Level logLevel, int maxFileSizeInMb, bool filterNh)
    {
        var filePatternLayout = new PatternLayout
        {
            ConversionPattern = "%date; [%thread]; %-5level; %logger; [%type{1}.%method]; - %message%newline"
        };
        filePatternLayout.ActivateOptions();
        var bediLogFileAppender = new RollingFileAppender
        {
            File = logFilePath,
            AppendToFile = true,
            MaximumFileSize = $"{maxFileSizeInMb}MB",
            MaxSizeRollBackups = 5,
            RollingStyle = RollingFileAppender.RollingMode.Size,
            LockingModel = new FileAppender.MinimalLock(),
            Layout = filePatternLayout,
            StaticLogFileName = true,
            Threshold = logLevel
        };
        if (filterNh)
        {
            bediLogFileAppender.AddFilter(new LoggerMatchFilter
            {
                LoggerToMatch = "NHibernate",
                AcceptOnMatch = false
            });
            bediLogFileAppender.AddFilter(new LoggerMatchFilter
            {
                LoggerToMatch = "NHibernate.SQL",
                AcceptOnMatch = false
            });
            bediLogFileAppender.AddFilter(new LoggerMatchFilter
            {
                LoggerToMatch = "FluentNHibernate",
                AcceptOnMatch = false
            });
        }
        bediLogFileAppender.ActivateOptions();
        bedInventoryLogger.AddAppender(bediLogFileAppender);
    }

由于我使用了多个日志，所以追加程序etd并想关闭NHibernate日志记录(我将NHibernate 4用作ORM)等.我发现用C#进行配置比使用XML更方便.

Since I used several logs, appenders etd and wanted to turn off NHibernate logging (I am using NHibernate 4 as ORM) etc. I found it more convenient to do configuration in C# than in XML.

是否可以将其与ServiceStack挂钩，还是最好直接使用Log4Net?

Is it possible to hook this in with ServiceStack or do I better use Log4Net directly?

推荐答案

默认的ServiceStack Log4Net适配器不允许您注入已配置的Log4Net实例，但是适配器类很容易复制和修改，仅在这2个文件中基本上只是将呼叫转发到Log4Net:

The default ServiceStack Log4Net adapter doesn't allow you to inject a configured Log4Net instance however the adapter classes are easy to copy and modify which are just in this 2 files which basically just forward the calls to Log4Net:

• Log4NetFactory.cs
• Log4NetLogger.cs

• Log4NetFactory.cs
• Log4NetLogger.cs
