Structuremap不适用于MVC4

Question

我已经StructureMap多次使用MVC2/3而没有任何顾虑,但我想在MVC4中处理IoC是不同的.当我用于StructureMap处理MVC4中的IoC时,我得到以下异常:

没有为此对象定义的无参数构造函数

为什么？我没有在谷歌找到任何正确的结果,除了这个:IoC不工作在MVC4 这些是我的IoC类:

public static class IoC {
    public static IContainer Initialize() {
        ObjectFactory.Initialize(x =>
                    {
                        x.Scan(scan =>
                        {
                            //scan.Assembly("DLL.Core");
                            scan.Assembly("DLL.CMS");
                            scan.TheCallingAssembly();
                            scan.WithDefaultConventions();
                        });
                        x.For<IDbContext>().Use<ModelEntities>();
                        x.For(typeof(IRepository<>)).Use(typeof(Repository<>));
                        x.For<IHttpControllerActivator>();
                        x.For<IController>();
                    });

        return ObjectFactory.Container;
    }

而SmDependencyResolver是:

    public class SmDependencyResolver : IDependencyResolver
{
    private readonly IContainer _container;

    public SmDependencyResolver(IContainer container)
    {
        _container = container;
    }

    public object GetService(Type serviceType)
    {
        if (serviceType == null) return null;
        try
        {
            return serviceType.IsAbstract || serviceType.IsInterface
                     ? _container.TryGetInstance(serviceType)
                     : _container.GetInstance(serviceType);
        }
        catch
        {

            return null;
        }
    }

    public IEnumerable<object> GetServices(Type serviceType)
    {
        return _container.GetAllInstances(serviceType).Cast<object>();
    }
}

我的错误是:

没有为此对象定义的无参数构造函数.描述:执行当前Web请求期间发生未处理的异常.请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息.

谢谢你的正确答案.

ooops.I找到了紧急解决方案:)尝试从IControllerActivator实现一个类

   public class StructureMapControllerActivator : IControllerActivator
    {
        private IContainer _container;

        public StructureMapControllerActivator(IContainer container)
        {
            _container = container;
        }

        public IController Create(RequestContext requestContext, Type controllerType)
        {
            return _container.GetInstance(controllerType) as IController;
        }
}

然后将其注册到IoC类:

 x.For<IControllerActivator>().Use<StructureMapControllerActivator>();

然后享受它.祝好运
