StructureMap找不到HttpServerUtility的默认实例

ioc-container structuremap c#

我有一门课 HttpServerUtilityBase HttpServerUtilityWrapper 作为默认实例。没什么奇怪的。但是,一旦我将声明添加到注册表中,structuremap就无法解析该实例,并且出现了一个错误。

public class ApplicationRegistry : Registry
{
    public ApplicationRegistry()
    {
        Scan(scanThe =>
        {
            scanThe.AssembliesFromApplicationBaseDirectory();
            scanThe.WithDefaultConventions();
        });

        Scan(scanThe =>
        {
            scanThe.AssemblyContainingType<HttpServerUtilityBase>();
        });

        SetAllProperties(x =>
        {
            x.WithAnyTypeFromNamespaceContainingType<IFinancialYearRepository>();
            x.WithAnyTypeFromNamespaceContainingType<IUserManagementFacade>();
            x.WithAnyTypeFromNamespaceContainingType<IBulkTypeImporter>();
            x.OfType<ILog>();
            x.OfType<ISessionManager>();
        });

        For<IUnitOfWork>()
            .HttpContextScoped()
            .Use(() => new EFUnitOfWork(
                    ConfigurationManager.ConnectionStrings["PublishedEFSqlServer"].ConnectionString
                    )).Named("publishedUnitOfWork");

        For<IUnitOfWork>()
            .HttpContextScoped()
            .Use(() => new EFUnitOfWork(
                ConfigurationManager.ConnectionStrings["UnpublishedEFSqlServer"].ConnectionString
                )).Named("unpublishedUnitOfWork");

        For<ILog>()
            .AlwaysUnique()
            .Use(s =>
            {
                ILog loggger;
                if (s.ParentType == null)
                {
                    loggger = LogManager.GetLogger(s.BuildStack.Current.ConcreteType);
                }
                else
                {
                    loggger = LogManager.GetLogger(s.ParentType);
                }

                if (HttpContext.Current.User != null && HttpContext.Current.User.Identity.IsAuthenticated)
                {
                    ThreadContext.Properties["user"] = HttpContext.Current.User.Identity.Name;
                }
                return loggger;
            });

        For<ISessionManager>().Singleton();

        For<HttpServerUtilityBase>()
            .Singleton()
            .Use<HttpServerUtilityWrapper>();
    }
}

我觉得一切都很好,但很明显我错过了什么。也可以通过调用 WhatDoIHave() 它引用了HttpServerUtilityBase,似乎引用了 HttpServerUtilityWrapper程序

HttpServer实用程序库(System.Web.HttpServer实用程序库)3bf840df-e159-4dcf-93ef-211bb7484698配置的实例System.Web.HttpServerUtilityWrapper文件, 系统.Web,版本=4.0.0.0,区域性=中性,PublicKeyToken=b03f5f7f11d50a3a
范围为:单例

结果发现解决办法很简单。我需要为 HttpServerUtilityWrapper

For<HttpServerUtilityBase>()
    .Singleton()
    .Use<HttpServerUtilityWrapper>()
    .Ctor<HttpServerUtility>().Is(HttpContext.Current.Server);
