Autofac財產注射

Question

我有基地controlller我嘗試屬性注射，但沒有工作...

public class BaseController : Controller 
{ 
    public ILoggingService loggingService { get; set; } 

    public BaseController() 
    { 

    } 
} 

這是我Autofac配置...

var builder = new ContainerBuilder(); 

// builder.Register(c => new BaseController { loggingService = c.Resolve<ILoggingService>() }); 
builder.RegisterControllers(Assembly.GetExecutingAssembly()) 
        .PropertiesAutowired(); 

builder.Register(c => new BaseController()).OnActivated(e => 
{ 
    e.Instance.loggingService = e.Context.Resolve<ILoggingService>(); 
}); 
builder.RegisterAssemblyTypes(Assembly.Load("Aizen.Services")) 
        .Where(t => t.Name.EndsWith("Service")) 
        .AsImplementedInterfaces() 
        .InstancePerRequest(); 

Answer 1

您還沒有註冊一個你的ILoggingService接口的具體類型。沒有這一點，Autofac不知道它真正需要設置你的財產。

添加這樣的事情（當然真正的對象替換）：

builder.RegisterType<YourLoggingServiceGoesHere>().As<ILoggingService>(); 

Answer 2

你可以試試這個解決方案：

builder.Register(c => new BaseController { loggingService = c.Resolve<ILoggingService>() });
