Question

我有基础控制器我尝试了属性注入，但没有工作......

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

    public BaseController()
    {

    }
}

这是我的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

您尚未为ILoggingService界面注册具体类型。没有它，Autofac不知道将你的财产设置为实际需要什么。

添加这样的东西（当然替换为真实对象）：

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

Answer 2

您可以尝试此解决方案：

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

Autofac属性在基本控制器中注入
