asp.net-mvc – 使用ASP.NET MVC,Linq To SQL和StructureMap导致

> ASP.NET MVC 1.0
> StructureMap 2.6.1

我在这里创建了一个bootstrapper类：

Imports StructureMap
Imports DCS.Data
Imports DCS.Services

Public Class BootStrapper

    Public Shared Sub ConfigureStructureMap()

        ObjectFactory.Initialize(AddressOf StructureMapRegistry)

    End Sub

    Private Shared Sub StructureMapRegistry(ByVal x As IInitializationExpression)

        x.AddRegistry(New MainRegistry())
        x.AddRegistry(New DataRegistry())
        x.AddRegistry(New ServiceRegistry())
        x.Scan(AddressOf StructureMapScanner)

    End Sub

    Private Shared Sub StructureMapScanner(ByVal scanner As StructureMap.Graph.IAssemblyScanner)

        scanner.Assembly("DCS")
        scanner.Assembly("DCS.Data")
        scanner.Assembly("DCS.Services")
        scanner.WithDefaultConventions()

    End Sub

End Class

我在这里创建了一个控制器工厂：

Imports System.Web.Mvc
Imports StructureMap

Public Class StructureMapControllerFactory
    Inherits DefaultControllerFactory

    Protected Overrides Function GetControllerInstance(ByVal controllerType As System.Type) As System.Web.Mvc.IController

        Return ObjectFactory.GetInstance(controllerType)

    End Function

End Class

我修改了Global.asax.vb,如下所示：

...
    Sub Application_Start()

        RegisterRoutes(RouteTable.Routes)

        'StructureMap
        BootStrapper.ConfigureStructureMap()
        ControllerBuilder.Current.SetControllerFactory(New StructureMapControllerFactory())

    End Sub
...

我已经为我的三个项目中的每一个添加了一个Structure Map注册表文件：DCS,DCS.Data和DCS.Services.这是DCS.Data注册表：

Imports StructureMap.Configuration.DSL

Public Class DataRegistry
    Inherits Registry

    Public Sub New()

        'Data Connections.
        [For](Of DCSDataContext)() _
            .HybridHttpOrThreadLocalScoped _
            .Use(New DCSDataContext())

        'Repositories.
        [For](Of IShiftRepository)() _
            .Use(Of ShiftRepository)()

        [For](Of IMachineRepository)() _
            .Use(Of MachineRepository)()

        [For](Of IShiftSummaryRepository)() _
            .Use(Of ShiftSummaryRepository)()

        [For](Of IOperatorRepository)() _
            .Use(Of OperatorRepository)()

        [For](Of IShiftSummaryJobRepository)() _
            .Use(Of ShiftSummaryJobRepository)()

    End Sub

End Class

就加载dependecies而言,一切都很好,但是我遇到了Linq2SQL Classes生成的DCSDataContext类的问题.

我有一个表单发布到详细信息页面(/ Summary / Details),它从SQL加载一些数据.然后我有一个按钮,在JQuery中打开一个对话框,它将对话框从请求填充到(/ Operator / Modify).在对话框中,表单有一个组合框和一个OK按钮,允许用户更改运算符的名称.单击“确定”后,表单将发布到(/ Operator / Modify)并通过程序的服务和存储库层发送,并更新数据库中的记录.然后,调用RedirectToAction将用户发送回详细信息页面(/ Summary / Details),在那里调用再次从SQL中提取数据,更新详细信息视图.

一切都很好,除了详细信息视图没有显示所选的新运算符.我可以单步执行代码并查看正在访问的DCSDataContext类以更新操作符(实际上确实更改了数据库记录),但是当访问DCSDataContext以重新加载详细信息对象时,它会提取旧值.我猜测StructureMap不仅会导致DCSDataContext类,还会导致数据被缓存？

我还尝试将以下内容添加到Global.asax中,但它最终导致程序崩溃,告诉我DCSDataContext已被处理…

Private Sub MvcApplication_EndRequest(ByVal sender As Object,ByVal e As System.EventArgs) Handles Me.EndRequest

   StructureMap.ObjectFactory.ReleaseAndDisposeAllHttpScopedObjects()

End Sub

有人可以帮忙吗？
