Unity MVC使用SOA和gereric Repository和UnitOfWork

Question

我正在尝试整合一个基于SOA的项目，并使用Gereric Repository和UnitOfWork以及Unity。

我的问题是，当控制器尝试初始化时，我收到以下错误：

无法构造String类型。您必须配置容器以提供此值。

我有以下Unity配置：

public static class UnityConfig
{ 

    #region Unity Container
    private static Lazy<IUnityContainer> container = new Lazy<IUnityContainer>(() =>
    {
        var container = new UnityContainer();
        RegisterTypes(container);
        return container;
    });

    /// <summary>
    /// Gets the configured Unity container.
    /// </summary>
    public static IUnityContainer GetConfiguredContainer()
    {
        return container.Value;
    }
    #endregion

    public static void RegisterTypes(IUnityContainer container)
    {

        // register all your components with the container here
        // it is NOT necessary to register your controllers

        // e.g. container.RegisterType<ITestService, TestService>();    

        container.RegisterType<IDataContextAsync, MyDbContext>(new PerRequestLifetimeManager())
                 .RegisterType<IRepositoryProvider, RepositoryProvider>(
                    new PerRequestLifetimeManager(),
                    new InjectionConstructor(new object[] { new RepositoryFactories() })
                    )
                 .RegisterType<IUnitOfWorkAsync, UnitOfWork>(new PerRequestLifetimeManager())
                 .RegisterType<IUnitOfWork, UnitOfWork>(new PerRequestLifetimeManager())
                 .RegisterType<IRepositoryAsync<ApplicationSetting>, Repository<ApplicationSetting>>()
                 .RegisterType<IApplicationSettingService, ApplicationSettingService>();

        container.RegisterType<IRepositoryProvider, RepositoryProvider>(new InjectionConstructor(container));


    }
}

以下Activator

using System.Linq;
using System.Web.Mvc;
using Microsoft.Practices.Unity.Mvc;
using XNETProductQuote.Web; 

[assembly: WebActivatorEx.PreApplicationStartMethod(typeof(UnityWebActivator), "Start")]
[assembly: WebActivatorEx.ApplicationShutdownMethod(typeof(UnityWebActivator), "Shutdown")]


namespace XNETProductQuote.Web  
{
    /// <summary>Provides the bootstrapping for integrating Unity with ASP.NET MVC.</summary>
    public static class UnityWebActivator
    {
        /// <summary>Integrates Unity when the application starts.</summary>
        public static void Start()
        {
            var container = UnityConfig.GetConfiguredContainer();

            FilterProviders.Providers.Remove(FilterProviders.Providers.OfType<FilterAttributeFilterProvider>().First());
            FilterProviders.Providers.Add(new UnityFilterAttributeFilterProvider(container));

            DependencyResolver.SetResolver(new UnityDependencyResolver(container));

            // TODO: Uncomment if you want to use PerRequestLifetimeManager
            Microsoft.Web.Infrastructure.DynamicModuleHelper.DynamicModuleUtility.RegisterModule(typeof(UnityPerRequestHttpModule));
        }

        /// <summary>Disposes the Unity container when the application is shut down.</summary>
        public static void Shutdown()
        {
            var container = UnityConfig.GetConfiguredContainer();
            container.Dispose();
        }
    }
}

我想加载的控制器是以下

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

using XNETProductQuote.Entities ;
using XNETProductQuote.Entities.Models;
using XNETProductQuote.Service;

namespace XNETProductQuote.Controllers
{
    public class ApplicationSettingController : Controller
    {

        private IApplicationSettingService service;

    public ApplicationSettingController(IApplicationSettingService svr)         
    { 
        service = svr;
    }

    //
    // GET: /ApplicationSetting/
    public ActionResult Index()
    {
        var applicationSettings = service.GetAll();
        return View(applicationSettings); 
    }



}

据我所知，Unityconfig注册了应该用于初始化控制器的IApplicationSettingService类型。

我错过了其他什么吗？

更新：

我得到的错误是

    }
