使用结构图注册通用类型

Question

我是结构图新手。我试图让 Structuremap 自动注册

public void RegisterAllEventHandlers()
{
    Scan(cfg =>
        {
            cfg.TheCallingAssembly();
            //cfg.IncludeNamespaceContainingType<NewCustomerCreated>();
            cfg.IncludeNamespace("ParentNameSpace");
            cfg.AddAllTypesOf(typeof (IHandle<NewCustomerCreated>));
        });

        //For(typeof (IHandle<>)).Use(typeof (NewCustomerCreated));
}

NewCustomerCreated 是事件，我想注册该事件的所有处理程序，即使用 IHandle

以下代码正在工作但我确信可以通过扫描来完成：-

ObjectFactory.Initialize(x =>
    {                                                      
        x.For(typeof(IHandle<NewCustomerCreated>))
            .Add(new NewCustomerCreatedHandler());                                                                        
        x.For(typeof(IHandle<NewCustomerCreated>))
            .Add(new SendWelcomeEmailToNewCustomer());
    });

我正在尝试使用 DomainEvent raiser http://blog.robustsoftware.co.uk/2009 /08/better-domain-event-raiser.html

编辑 1：从博客添加代码

 public interface IEventDispatcher
    {

        void Dispatch<TEvent>(TEvent eventToDispatch) where TEvent : IDomainEvent;

    }


    public static class DomainEventDispatcher
    {

        public static IEventDispatcher Dispatcher { get; set; }



        public static void Raise<TEvent>(TEvent eventToRaise) where TEvent : IDomainEvent
        {

            Dispatcher.Dispatch(eventToRaise);

        }

    }


    public class StructureMapEventDispatcher : IEventDispatcher
    {

        public void Dispatch<TEvent>(TEvent eventToDispatch) where TEvent : IDomainEvent
        {

            foreach (var handler in ObjectFactory.GetAllInstances<IHandle<TEvent>>())
            {

                handler.Handle(eventToDispatch);

            }

        }

从我的测试项目中，我调用注册表类，它将扫描程序集

  public void RegisterAllEventHandlers()
        {
            Scan(cfg =>
            {
                cfg.TheCallingAssembly();
                cfg.IncludeNamespace("Project1");
                //cfg.AddAllTypesOf(typeof(IHandle<NewCustomerCreated>));
                cfg.ConnectImplementationsToTypesClosing(typeof(IHandle<>));

            });

            // This initializes correctly 
            //ObjectFactory.Initialize(x =>
            //{
            //    x.For(typeof(IHandle<NewCustomerCreated>)).Add(new NewCustomerCreatedHandler());

            //}); 



          // Handler  returns 0 count 

          var handler =ObjectFactory.GetAllInstances<IHandle<NewCustomerCreated>>();





        }

，然后

var eventDispatcher = new StructureMapEventDispatcher();
            DomainEventDispatcher.Dispatcher = eventDispatcher;

Answer 1

试试这个：

cfg.AddAllTypesOf(typeof (IHandle<>));

然后你的容器将完成剩下的工作：

var handler = container.GetInstance<IHandler<NewCustomerCreated>>();
