发生异常ASP.Net在共享主机上使用Log4net的MVC应用程序

yellow-screen-of-death shared-hosting log4net exception asp.net-mvc

Saajid Ismail · 技术社区 · 16 年前

我有一个网站是用ASP.NetMVC,并使用Log4net进行异常日志记录。直到大约4小时前,这个网站一直运行良好。我们在过去两周内没有对网站进行任何更改。这个网站自从我们1个月前建立以来一直运行得很顺利。该网站是在我们的ISP托管共享托管帐户。

这是我们收到的例外情况:

[FormatException: String was not recognized as a valid Boolean.]
   log4net.Core.LoggerManager.RegisterAppDomainEvents() +0
   log4net.Core.LoggerManager..cctor() +33

[TypeInitializationException: The type initializer for 'log4net.Core.LoggerManager' threw an exception.]
   log4net.Core.LoggerManager.GetLogger(Assembly repositoryAssembly, String name) +0
   log4net.LogManager.GetLogger(Assembly repositoryAssembly, String name) +8
   log4net.LogManager.GetLogger(String name) +20
   i3t.LcaWeb.View.MvcApplication..cctor() in Global.asax.cs:17

[TypeInitializationException: The type initializer for 'i3t.LcaWeb.View.MvcApplication' threw an exception.]
   i3t.LcaWeb.View.MvcApplication..ctor() +0
   ASP.global_asax..ctor() in App_global.asax.fqjmwqjv.0.cs:0

[TargetInvocationException: Exception has been thrown by the target of an invocation.]
   System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean noCheck, Boolean& canBeCached, RuntimeMethodHandle& ctor, Boolean& bNeedSecurityCheck) +0
   System.RuntimeType.CreateInstanceSlow(Boolean publicOnly, Boolean fillCache) +86
   System.RuntimeType.CreateInstanceImpl(Boolean publicOnly, Boolean skipVisibilityChecks, Boolean fillCache) +230
   System.Activator.CreateInstance(Type type, Boolean nonPublic) +67
   System.RuntimeType.CreateInstanceImpl(BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes) +1051
   System.Activator.CreateInstance(Type type, BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes) +111
   System.Web.HttpApplicationFactory.GetSpecialApplicationInstance(IntPtr appContext, HttpContext context) +215
   System.Web.HttpApplicationFactory.FireApplicationOnStart(HttpContext context) +8878568
   System.Web.HttpApplicationFactory.EnsureAppStartCalled(HttpContext context) +136
   System.Web.HttpApplicationFactory.GetApplicationInstance(HttpContext context) +92
   System.Web.HttpRuntime.ProcessRequestInternal(HttpWorkerRequest wr) +289

log4net.ILog 正在创建:

public class MvcApplication : System.Web.HttpApplication
{
    private static log4net.ILog log = log4net.LogManager.GetLogger("global.asax");

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            "Home.aspx",
            "",
            new { action = "Index", controller = "Home" }
        );

这个问题不会在测试中发生,我们无法重现。我已经删除了现场网站上的所有文件,并重新上传,以防有东西被破坏,但这并没有解决问题。

有什么解决这个问题的线索吗?

我也有类似的问题。在我的情况下,我意外地在Web.config文件作为不是布尔值的东西。

<appender name="XYLogger" type="log4net.Appender.RollingFileAppender">
    <file value="App_Data\logging\xymaps.log" />
    <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
    <appendToFile value="some-file-name"/>
    <rollingStyle value="Size" />
    <maxSizeRollBackups value="2" />
    <maximumFileSize value="2MB" />
    <staticLogFileName value="true" />
    <layout type="log4net.Layout.PatternLayout">
        <param name="ConversionPattern" value="%d [%t] %-tp %c %m%n" />
    </layout>
</appender>

我搞错了 <appendToFile> 作为指定记录器应附加到的文件名的标记。相反,它应该读到 <appendToFile value="true" /> . 如果有人碰到他们的问题,我建议他们再检查一次Web.config文件对于具有错误值的布尔字段。

LogManager.GetLogger()需要用于日志记录的类的名称,而不是全局.asax,它是文件的名称。请仅使用“Global”作为参数LogManager.GetLogger().
