我刚开始学习使用IoC容器,因此选择了Ninject。
经过几个小时的努力,我仍然无法弄清如何在我的MVC3应用程序中设置Ninject。
到目前为止,我已经做了以下工作:
Global.asax.cs
public class MvcApplication : Ninject.Web.Mvc.NinjectHttpApplication
{
public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
filters.Add(new HandleErrorAttribute());
}
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
}
protected void Application_Start()
{
DependencyResolver.SetResolver(new MyDependencyResolver(CreateKernel()));
RegisterGlobalFilters(GlobalFilters.Filters);
RegisterRoutes(RouteTable.Routes);
}
protected override IKernel CreateKernel()
{
var modules = new [] { new ServiceModule() };
return new StandardKernel(modules);
}
}
ServiceModule.cs
internal class ServiceModule : NinjectModule
{
public override void Load()
{
Bind<IGreetingService>().To<GreetingService>();
}
}
MyDependencyResolver.cs
public class MyDependencyResolver : IDependencyResolver
{
private IKernel kernel;
public MyDependencyResolver(IKernel kernel)
{
this.kernel = kernel;
}
public object GetService(System.Type serviceType)
{
return kernel.TryGet(serviceType);
}
public System.Collections.Generic.IEnumerable<object> GetServices(System.Type serviceType)
{
return kernel.GetAll(serviceType);
}
}
GreetingService.cs
public interface IGreetingService
{
string Hello();
}
public class GreetingService : IGreetingService
{
public string Hello()
{
return "Hello from GreetingService";
}
}
TestController.cs
public class TestController : Controller
{
private readonly IGreetingService service;
public TestController(IGreetingService service)
{
this.service = service;
}
public ActionResult Index()
{
return View("Index", service.Hello());
}
}
每次尝试加载索引视图时,它要么会抛出溢出异常,要么会出现HTTP 404错误 - 如果我删除所有的Ninject代码,它就能正常工作,出了什么问题?
NinjectHttpApplication
吗?我应该把我的旧代码void Global_PostReleaseRequestState(object sender, EventArgs e)
,public override void Init()
和void Global_PreRequestHandlerExecute(object sender, EventArgs e)
放在哪里? - Maslow
