使用依赖注入

Question

我继承ApiController及以下初始化抽象类的对象是我重写ExecuteAsync方法依赖注入，

public abstract class BaseController : ApiController 
{ 
    private IMyService _myService; 
    public PersonModel person; 
    protected BaseController(IMyService myService) 
    { 
     _myService = myService; 
    } 

    public override Task<HttpResponseMessage> ExecuteAsync(HttpControllerContext controllerContext, CancellationToken cancellationToken) 
    { 
     _myService.Initialize(person); 
    } 
} 

这是我的服务接口，

public interface IMyService 
{ 
    HttpResponseMessage Initialize(PersonModel person); 
} 

这里是类，

public class MyService : IMyService 
{ 
    public HttpResponseMessage Initialize(PersonModel person) 
    { 
     //Initializing person model from db 
     return new HttpResponseMessage(HttpStatusCode.OK); 
    } 
} 

当我执行这个方法时，person对象在BaseController类仍然为空。我应该改变什么来初始化抽象类中的对象？

请检查此线程，看看这个回答你的问题 - Registering implementations of base class with Autofac to pass in via IEnumerable

你将不得不适当地注册您的抽象类的子类。
