asp.net - 无法让 Log4Net 在我的 ASP.NET 网站中工作 :(

Question

非常简单的问题 -> 在我的 ASP.NET 应用程序中，我似乎无法从 Log4Net 获取任何数据。我有一个简单的 ASP.NET 网站，它引用了一个类库。在这个类库中，我有一些调用记录器的行。

我正在尝试在我的 Visual Studio 2008 调试输出窗口中读取 log4net 输出数据 .

这是我的代码和我的配置...

//Class Library project
//File: Foo.cs
public class FooService
{
    private static readonly ILog log = LogManager.GetLogger(typeof(FooService));

    public FooService()
    {
        // NOTE: To play with my L4N settings, I'll call Debug once, then Info once.

        log.Info("Starting Constructor");

        // ... snip ...

        log.Debug("Leaving Constructor");
    }
}


// ASP.NET Website project
// File: global.asax
void Application_Start(object sender, EventArgs eventArgs) 
{
    log4net.Config.XmlConfigurator.Configure();
}

// File: Whatever.aspx.cs
// A delegate method (when a user clicks a button) creates the FooService() instance.

// File: web.config
<configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler" requirePermission="false" />

    // ....

</configSections>


<log4net>
    <appender name="ColoredConsoleAppender" type="log4net.Appender.ColoredConsoleAppender">
        <mapping>
            <level value="ERROR" />
            <foreColor value="White" />
            <backColor value="Red, HighIntensity" />
        </mapping>
        <mapping>
            <level value="DEBUG" />
            <backColor value="Green" />
        </mapping>
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
        </layout>
    </appender>

    <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
        <layout type="log4net.Layout.PatternLayout" value="%date [%thread] %-5level %logger - %message%newline" />
    </appender>

    <appender name="OutputDebugStringAppender" type="log4net.Appender.OutputDebugStringAppender">
        <mapping>
            <level value="ERROR" />
            <foreColor value="White" />
            <backColor value="Red, HighIntensity" />
        </mapping>
        <mapping>
            <level value="DEBUG" />
            <backColor value="Blue" />
        </mapping>
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
        </layout>
    </appender>


    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
        <file value="App_Data\logging\log-append.txt"/>
    </appender>

    <!-- Setup the root category, add the appenders and set the default level -->
    <root>
        <level value="ALL" />
        <appender-ref ref="OutputDebugStringAppender" />
        <appender-ref ref="ConsoleAppender" />
        <appender-ref ref="ColoredConsoleAppender" />
    </root>
    <!-- Specify the level for some specific categories -->
    <logger name="DotNetOpenAuth">
        <level value="ALL" />
    </logger>
</log4net>

为任何帮助或建议干杯...

编辑:添加了 RollingLogFileAppender。

Answer 1

ASP.Net 对文件系统访问的使用有限制，因此尝试明确指向 App_Data 下的目录(是否允许)
这是我的工作示例:

<log4net>
    <appender name="FileAppender" type="log4net.Appender.FileAppender">
        <file value="App_Data\logging\log-file.txt"/>

或者有翻车

    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
        <file value="App_Data\logging\log-append.txt"/>
