在使用StructureMap在WebAPI中实现DI时，我们使用了在中的ServiceActivator
> Configuring Dependency Injection with ASP.NET WebAPI 2.1
> WebAPI + APIController with structureMap
public class ServiceActivator : IHttpControllerActivator
{
public ServiceActivator(HttpConfiguration configuration) {}
public IHttpController Create(HttpRequestMessage request,HttpControllerDescriptor controllerDescriptor,Type controllerType)
{
var controller = ObjectFactory.GetInstance(controllerType) as IHttpController;
return controller;
}
}
但现在有了新的StructureMap，我的ReSharper建议：
Class ‘StructureMap.ObjectFactory’ is obsolete: ObjectFactory will be removed in a future 4.0 release of StructureMap. Favor the usage of the Container class for future work
集装箱上的智能感觉给我的信息非常有限。
我们应该如何用Container类重写我们的ServiceActivator？
解决方法
该
static stuff is going away.如果不使用某种类型的服务定位器，你将不得不实现自己“的ObjectFactory”为
referenced here：
public static class ObjectFactory
{
private static readonly Lazy<Container> _containerBuilder =
new Lazy<Container>(defaultContainer,LazyThreadSafetyMode.ExecutionAndPublication);
public static IContainer Container
{
get { return _containerBuilder.Value; }
}
private static Container defaultContainer()
{
return new Container(x =>
{
// default config
});
}
}
更新：我以前的答案是错误的。感谢@JoeMighty的头。
