Asp.net 结构图、实体框架和IRepository/IUnitOfWork配置

我正在ASP.NET MVC应用程序上使用带有实体框架和IRepository/IUnitOfWork模式的StructureMap。目标是将所有对象的作用域限定为当前HTTP请求，如下所示：

For<ObjectContext>()
    .HttpContextScoped()
        .Use<MembershipEntities>()
            .Ctor<string>("connectionString")
                .Is("name=MembershipEntities")
        .Named(MembershipObjectContextInstanceKey);

For<IObjectContext>()
    .HttpContextScoped()
        .Use<ObjectContextAdapter>()
            .Ctor<ObjectContext>("objectContext")
                .Is(c => c.GetInstance<ObjectContext>(MembershipObjectContextInstanceKey))
        .Named(MembershipIObjectContextInstanceKey);

For<IUnitOfWork>()
    .HttpContextScoped()
        .Use<UnitOfWork>()
            .Ctor<IObjectContext>("objectContext")
                .Is(x => x.GetInstance<IObjectContext>(MembershipIObjectContextInstanceKey))
        .Named(MembershipUOWInstanceKey);

For(typeof(IRepository<>))
    .HttpContextScoped()
        .Use(typeof(Repository<>))
            .CtorDependency<IObjectContext>("objectContext")
                .IsNamedInstance(MembershipIObjectContextInstanceKey)
        .Named(MembershipIRepositoryInstanceKey);

但是，当我运行此代码并获得IRepository和IUnitOfWork的命名实例时，它们的内部IObjectContext不是同一个实例，这不是我的意图

你知道我做错了什么吗？任何帮助都将不胜感激

StructureMap支持两种形式的依赖项注入：

构造函数注入-通过构造函数参数将依赖项推送到具体类中。 Setter注入-通过公共属性将依赖项推送到具体类中。塞特命名法取自 Java，其中属性为GetSomethingValue和setSomethingvalue。 我使用类似于以下的配置获得了很好的结果：

// In my projects, I have something like a DataContext (IDataContext's implementation) expose my ObjectContext...
// * You don't need to HttpContextScope everything, usually the ObjectContext is sufficient
For<ObjectContext>()
    .HttpContextScoped()
    .Use<MembershipEntities>()
    .Ctor<string>("connectionString")
    .Is("name=MembershipEntities")
    .Named(MembershipObjectContextInstanceKey);

// Usually, I don't abstract or wrap the ObjectContext, it is simply injected, under the hood
// ObjectContextAdapter receives an ObjectContext (HttpContextScoped)
For<IObjectContext>().Use<ObjectContextAdapter>();

// Ctor receives a IObjectContext
// * Again, if you have absolutely no use for IObjectContext, it shouldn't exist and UnitOfWork's ctor should receive the HttpContextScoped ObjectContext
For<IUnitOfWork>().Use<UnitOfWork>();

// Ctor receives a IObjectContext [...]
For(typeof(IRepository<>)).Use(typeof(Repository<>));

每次我都或多或少是这样做的

让我知道它是否适合你。 真诚地 马克斯
