StructureMap找不到HttpServerUtility的默认实例

Question

我有一个依赖于HttpServerUtilityBase的类，我的计划是让结构映射使用HttpServerUtilityWrapper作为默认实例。那里没什么奇怪的。但是，一旦我将声明添加到我的注册表中，structuremap就无法解析实例，并得到一个202错误。

这是我的注册表：

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>();
    }
}

在我看来一切都很好，但很明显我错过了什么。另外，调用WhatDoIHave() (引用HttpServerUtilityBase )生成的行似乎有一个对HttpServerUtilityWrapper的引用，所以我认为它应该能正常工作。

HttpServerUtilityBase (System.Web.HttpServerUtilityBase) 3bf840df-e159-4 4dcf 93ef-211bb7484698配置的System.Web.HttpServerUtilityWrapper、System.Web、Version=4.0.0.0、Culture=neutral、PublicKeyToken=b03f5f7f11d50a3a的配置实例

范围为: Singleton

我遗漏了什么？

结果发现修复方法很简单。我需要为HttpServerUtilityWrapper指定构造函数参数

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