使用ASP.NET MVC的log4net:没有任何反应

我正在尝试将log4net与ASP.NET MVC一起使用,但我无法发生任何事情 . 我已经在我的web项目根目录中创建了一个配置:

<log4net>
    <root>
        <level value="INFO" />
        <appender-ref ref="RollingLogFileAppender"/>
    </root>

    <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
        <file value="C:\DWSApplicationFiles\AppLogs\app.log" />
        <appendToFile value="true" />
        <rollingStyle value="Size" />
        <maxSizeRollBackups value="10" />
        <maximumFileSize value="100KB" />
        <staticLogFileName value="true" />
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%d [%t]%-5p %c [%x] - %m%n" />
        </layout>
    </appender>

    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
        <file value="C:\DWSApplicationFiles\AppLogs\app.log" />
        <appendToFile value="false" />
        <datePattern value="-dddd" />
        <rollingStyle value="Date" />
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%d [%t]%-5p %c [%x] - %m%n" />
        </layout>
    </appender>
</log4net>

在我被问到之前:是的,应用程序有权写入目录 . 我已对此进行了测试,该应用程序已获得此目录的权限 .

这是我尝试使用log4net的地方:

public class HomeController : Controller
{
    readonly log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
    public ActionResult Index()
    {
        log.Error("In Index  ");
         return View();
    }
}

当我运行应用程序并转到此控制器时,log4net什么都不做;它不会在该目录或任何内容中创建文件 .

我已经为log4net启用了内部调试,我在控制台中没有输出错误 . 以下是我在log4net上看到的全部内容:

log4net:log4net assembly [log4net,Version = 1.2.10.0,Culture = neutral,PublicKeyToken = 1b44e1d426115821] . 从[C:\ Users \ twaldron.BULLFROGSPAS \ AppData \ Local \ Temp \ Temporary ASP.NET Files \ root \ 7642c99a \ 60feb7f2 \ assembly \ dl3 \ 17247033 \ 008dfd6d_e2d0ca01 \ log4net.DLL]加载 .

你在global.asax中有这样的东西吗?

void Application_Start(object sender, EventArgs e)
{
    string l4net = Server.MapPath("~/log4net.config");
    log4net.Config.XmlConfigurator.ConfigureAndWatch(new System.IO.FileInfo(l4net));

    ...

确保你打电话

log4net.Config.XmlConfigurator.Configure();

在您的应用程序启动时 .

在ASP.NET MVC 4 Web应用程序中配置Log4Net

<configuration> 
    <configSections>
        <section
            name="log4net"
            type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
    </configSections>
    <log4net>
        <appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender">
            <param name="File" value="LOGS\log.txt"/>
            <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
            <appendToFile value="true" />
            <rollingStyle value="Size" />
            <maxSizeRollBackups value="2" />
            <maximumFileSize value="10MB" />
            <staticLogFileName value="true" />
            <layout type="log4net.Layout.PatternLayout">
                <param name="ConversionPattern" value="%d [%t] %-5p %c %m%n"/>
            </layout>
        </appender>
        <root>
            <level value="ALL" />
            <appender-ref ref="LogFileAppender" />
        </root> 
        <logger name="test">
            <level value="DEBUG"></level>
        </logger>
    </log4net>
</configuration>
  • 修改AssemblyInfo.cs:
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "Web.config", Watch = true)]
  • 修改global.asax.cs:
protected void Application_Start()
{
    log4net.Config.XmlConfigurator.Configure(new FileInfo(Server.MapPath("~/Web.config")));
}
  • 在要为其创建日志的类中添加 Logger 声明:
readonly log4net.ILog log =
    log4net.LogManager.GetLogger(
        System.Reflection.MethodBase.GetCurrentMethod().DeclaringType
    );
  • 使用日志功能:
log.Error("make mistakes");

在AssemblyInfo.cs中添加以下行:

[assembly:log4net.Config.XmlConfigurator(Watch = true)]
