我是StructureMap的新手，我一直試圖修復這個錯誤一段時間。 只是不知道如何解決它，我在哪裏做錯了。 我甚至設置了一個模板MVC4網站，沒有任何內容，仍然得到這個錯誤。結構圖沒有爲此對象定義的無參數構造函數
有人可以幫我嗎？

public static IContainer Initialize() {
ObjectFactory.Initialize(x =>

scan.WithDefaultConventions();
});
x.For<IDbSession>().Use(() => MvcApplication.DbSession);
x.For<IDbService>().Use<DbService>();
});
return ObjectFactory.Container;
}
