Question

我想将HaveBox用于依赖注入。但这不是HaveBox的问题。所以我创建了基本控制器：

public abstract class BaseController : Controller
    {
        protected  readonly IRepository m_Repository;

        protected BaseController(IRepository repository)
        {
            m_Repository = repository;
        }
    }

我的HomeController继承自BaseController。将HaveBoxConfig.RegisterTypes();添加到Application_Start方法并HaveBoxConfig的实施是：

 public class HaveBoxConfig
    {
        public static void RegisterTypes()
        {
            var container = new Container();
            container.Configure(config => config.For<IService>().Use<Service>());
            container.Configure(config => config.For<IRepository>().Use<Repository>());
            IDependencyResolver resolver = DependencyResolver.Current;
            var newResolver = new MyResolver(container, resolver);
            DependencyResolver.SetResolver(newResolver);
        }
    }

我的解析器：

public class MyResolver : IDependencyResolver
    {
        private readonly IContainer m_container;
        private readonly IDependencyResolver m_resolver;
        public MyResolver(IContainer container, IDependencyResolver resolver)
        {
            m_container = container;
            m_resolver = resolver;
        }
        public object GetService(Type serviceType)
        {
            try
            {
                return m_container.GetInstance(serviceType);
            }
            catch (Exception ex)
            {
                return m_resolver.GetService(serviceType);
            }
        }
        public IEnumerable<object> GetServices(Type serviceType)
        {
            return m_resolver.GetServices(serviceType);
        }
    }

方法GetService要求使用下一种类型：IControllerFactory，IControllerActivator，HomeController，但不适用于我的IRepository。

我做错了什么？为什么没有为IRepository执行DI？

Answer 1

您还需要实现控制器工厂。最简单的方法是继承DefaultControllerFactory。您可以使用Castle Windsor检查他们是如何做到的。然后你告诉ASP.NET MVC使用你的实现。

DependencyResolver.SetResolver(newResolver);
ControllerBuilder.Current.SetControllerFactory(controllerFactory);

Answer 2

我已经检查了不同的解决方法。最简单的只是将我的控制器添加到容器中。例如：

container.Configure(config => config.For<HomeController>().Use<HomeController>());

简单明了。如果您有复杂的项目和更优雅的解决方案，您可以通过反映实现IController接口的所有类。

依赖注入不知道我想要注入的类型
