asp.net-mvc-3 – 是否需要StructureMap HttpContextScoped？

protected void Application_Start()
    {
        ...

        initStructureMap();

    }

    private static void initStructureMap()
    {

        ObjectFactory.Initialize(x =>
        {
            x.For<IUnitOfWork>().HttpContextScoped().Use(() => new Context());
            x.For<IFirstEntity>().Use<FirstEntity>();
            x.For<ISecondEntity>().Use<SecondEntity>();
            x.For<IThirdEntity>().Use<ThirdEntity>();
        });

        ControllerBuilder.Current.SetControllerFactory(new StructureMapControllerFactory());
    }

    protected void Application_EndRequest(object sender,EventArgs e)
    {
        ObjectFactory.ReleaseAndDisposeAllHttpScopedObjects();
    }


public class StructureMapControllerFactory : DefaultControllerFactory
{
    protected override IController GetControllerInstance(RequestContext requestContext,Type controllerType)
    {
        return ObjectFactory.GetInstance(controllerType) as Controller;
    }
}

FirstEntity,SecondEntity和……都需要在构造函数中使用IunitOfWork.

正如你所看到的那样,只使用HttpContextScoped()用于Context而不是其他用户,在EndRequest事件中它调用ReleaseAndDisposeAllHttpScopedObjects().

1-这是一个正确的方法吗？

2-我应该将HttpContextScoped()用于所有其他服务层接口,还是仅用于IUnitOfWork？例如

x.For<IFirstEntity>().Use<FirstEntity>();

要么

x.For<IFirstEntity>().HttpContextScoped().Use(() => new FirstEntity());

3- ReleaseAndDisposeAllHttpScopedObjects()处理所有实例还是只处置Context？
