asp.net-mvc - Nopcommerce 新表服务注册错误

Question

请帮帮我。我坚持服务注册。我尝试了谷歌的每一个可能方面，但无法得出结论。我想要做的是创建一个新表 EducationDegree，一个主表。消费者随后将被分配教育学位。
我的问题与 EducationDegreeService 注册有关。请参阅在 Nop.web>Controllers> CustomController.cs 中创建的构造函数和在 Nop.web>Framework> dependencyregister.cs 中完成的注册。附加代码评论为 //由 Shyam 添加已经一个多星期了，我一直没能破解。所以请帮帮我。

下面是错误信息

在“Nop.Web.Controllers.CustomerController”类型上使用“Autofac.Core.Activators.Reflection.DefaultConstructorFinder”找到的构造函数都不能用可用的服务和参数调用:无法解析构造函数'Void .ctor(Nop.Services.Authentication.IAuthenticationService，Nop.Services.Helpers.IDateTimeHelper，Nop.Services.Helpers.DateTimeSettings，Nop.Core.Domain。 Tax.TaxSettings，Nop.Services.Localization.ILocalizationService，Nop.Core.IWorkContext，Nop.Core.IStoreContext，Nop.Services.Stores.IStoreMappingService，Nop.Services.Customers.ICustomerService，Nop.Services.Customers.ICustomerAttributeParser，Nop。服务。客户Nop.Core.Domain.Common.AddressSettings，Nop.Core.Domain.Forums.ForumSettings，Nop.Core.Domain.Orders.OrderSettings，Nop.Services.Common.IAddressService，Nop.Services.Directory.ICountryService，Nop.Services。可怕的ctory.IStateProvinceService，Nop.Services.Orders.IOrderTotalCalculationService，Nop.Services.Orders.IOrderProcessingService，Nop.Services.Orders.IOrderService，Nop.Services.Directory.ICurrencyService，Nop.Services.Catalog.IPriceFormatter，Nop.Services.Media。 IPictureService，Nop.Services.Messages.INewsLetterSubscriptionService，Nop.Services.Forums.IForumService，Nop.Services.Orders.IShoppingCartService，Nop.Services.Authentication.External.IOpenAuthenticationService，Nop.Services.Catalog.IBackInStockSubscriptionService，Nop.Services.Media。 IDownloadService、Nop.Core.IWebHelper、Nop.Services.Logging.ICustomerActivityService、Nop.Core.Domain.Media.MediaSettings、Nop.Services.Messages.IWorkflowMessageService、Nop.Core.Domain.Localization.LocalizationSettings、Nop.Web.Framework。 UI.Captcha.CaptchaSettings, Nop.Core.Domain.Customers.ExternalAuthenticationSettings, Nop.Services.EducationDegrees.EducationDegreeService)'

Answer 1

是的，你是对的 user3838557 :

Nop.Web.Controllers 构造函数声明。

而不是声明

"EducationDegreeService educationDegreeService"

你应该用过

IEducationDegreeService educationDegreeService"
