Web Api - 异常未记录

Question

我有以下class

    public class WebApiExceptionLoggingFilter : ExceptionFilterAttribute
{
    private readonly ILog _logger;

    public WebApiExceptionLoggingFilter(ILog logger)
    {
        this._logger = logger;
    }

    public override void OnException(HttpActionExecutedContext filterContext)
    {
        //Logging Exception
        _logger.Error("An unhandled exception was thrown", filterContext.Exception);

        //Changing exception message to something generic.
        var exceptionMessage = "An error occurred and logged during processing of this application.";

        //Throwing a proper message for the client side
        var message = new HttpResponseMessage(HttpStatusCode.InternalServerError)
        {
            Content = new StringContent(exceptionMessage),
            ReasonPhrase = exceptionMessage
        };

        throw new HttpResponseException(message);
    }
}

我正在注册它：

        public static void Register(HttpConfiguration config)
    {
        // Web API configuration and services

        // Web API routes
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{action}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );

        config.Filters.Add(new WebApiExceptionLoggingFilter(LogManager.GetLogger("Web Api Unhandled Exception Logger")));
    }

我为我的 mvc 控制器注册了另一个过滤器属性，它已在 FilterConfig.cs 文件中注册。当控制器操作中发生异常时，它会通过 log4net 记录到 windows 事件查看器。当在调用 Web api 控制器操作时发生异常时，将命中上述处理程序中的 OnException 方法并调用 _logger.log，但事件查看器不会记录任何内容。我错过了什么吗？

终于找到问题了

我的 assemblyinfo.cs

里有这个

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

我需要这个

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config",Watch = true)]

Web Api - 异常未记录

Web Api - Exception not logging

c#

exception

log4net
