大家好，我是环境MVC4RC wepapi和microsoft.practices.unity V2.0团结mvc4和的WebAPI相同的应用程序
我想用的IoC/DI在MVC控制器（从System.web.mvc.Controller继承）和webapi控制器（从System.web.http.ApiController继承）。问题是我不能同时工作，如果有人能帮助我，我会粘贴一些代码。
在的global.asax.cs
public class MvcApplication : System.Web.HttpApplication
{
private static IUnityContainer container;
protected void Application_Start()
{
....
InitializeDependencyInjectionContainer(GlobalConfiguration.Configuration);
}
private static void InitializeDependencyInjectionContainer(HttpConfiguration config)
{
container = new UnityContainer();
container.RegisterType<Site.Web.Data.IDatabaseFactory, Site.Web.Data.DatabaseFactory>();
container.RegisterType<Site.Web.Data.Interfaces.IUnitOfWork, Site.Web.Data.UnitOfWork>();
container.RegisterType<Site.Web.Data.Interfaces.IUserRepository, Site.Web.Data.Repositories.UserRepository>();
container.RegisterType<Site.Web.Data.Interfaces.ISiteRepository, Site.Web.Data.Repositories.SiteRepository>();
container.RegisterType<Site.Web.Data.Interfaces.IInformationRepository, Site.Web.Data.Repositories.InformationRepository>();
container.RegisterType<IUserServices, UserServices>();
container.RegisterType<ISiteServices, SiteServices>();
container.RegisterType<IInformationServices, InformationServices>();
container.RegisterType<IFormsAuthenticationService, FormsAuthenticationService>();
container.RegisterType<IMembershipService, MembershipService>();
//config.DependencyResolver = new Site.Web.IoC.IoCContainer(container);
DependencyResolver.SetResolver(new Site.Web.IoC.IoCContainer(container));
//DependencyResolver.SetResolver(new Site.Web.IoC.UnityDependencyResolver(container));
}
}
的IoC的解析器：
public class IoCContainer : System.Web.Mvc.IDependencyResolver
{
private readonly IUnityContainer container;
public IoCContainer(IUnityContainer container)
{
this.container = container;
}
public object GetService(Type serviceType)
{
try
{
return this.container.Resolve(serviceType);
}
catch (ResolutionFailedException)
{
return null;
}
}
public IEnumerable<object> GetServices(Type serviceType)
{
try
{
return this.container.ResolveAll(serviceType);
}
catch (ResolutionFailedException)
{
return new List<object>();
}
}
}
注：System.Web.Mvc.IDependencyResolver而不是System.Web.Http.Dependencies.IDependencyResolver
现在控制器都具有相同的结构，我使用常见的类来提供用户和站点信息（如codeplex/Silk的样式）
一个MVC的控制器：
public class SiteController : _AuthorizedController
{
ISiteServices _siteServices;
public SiteController(Site.Web.Domain.Services.IUserServices userServices,
Site.Web.Domain.Services.ISiteServices siteServices)
: base(userServices)
{
this._siteServices = siteServices;
}
....
}
的_AuthorizedController是我使用的一个具有所需的所有用户和地点信息：
public class _AuthorizedController : Controller
{
protected readonly Site.Web.Domain.Services.IUserServices _userServices;
public _AuthorizedController(Site.Web.Domain.Services.IUserServices userServices)
{
if (userServices == null) throw new ArgumentNullException("userServices");
this._userServices = userServices;
}
...
}
和一个的WebAPI控制器：
public class InformationController : _AuthorizedApiController
{
private ISiteServices _siteServices;
private IUserServices _userServices;
public InformationController(Site.Web.Domain.Services.IUserServices userServices,
Site.Web.Domain.Services.ISiteServices siteServices)
: base(userServices)
{
this._siteServices = siteServices;
this._userServices = userServices;
}
... }
和_AuthorizedApiController我创建preservethe继承链（ApiController）：
public class _AuthorizedApiController : ApiController
{
protected readonly Site.Web.Domain.Services.IUserServices _userServices;
public _AuthorizedApiController(Site.Web.Domain.Services.IUserServices userServices)
{
if (userServices == null) throw new ArgumentNullException("userServices");
this._userServices = userServices;
}
.....
}
以及这种结构适用于MVC控制器，但我没能上apicontroller运行。我会尝试根据Using the Web Api dependency...但没有运气改变的IoC
我总是有非常expresive错误“Site.Web.webapi.InformationController”没有默认的构造函数
赞赏的Tx任何帮助。
