automapper - NopCommerce 网络服务 DTO

Question

我正在尝试扩展 webservice plygin 以便从 nopcommerce 获取产品列表。

我所做的是以下。我创建了一个类似的类ProductDto，并在里面NopService.cs创建了一个类似的方法：

public List<ProductDto> GetProductCollection(string usernameOrEmail, string userPassword)

ProductDto取自Product使用 AutoMapper。（如下图）

但它不起作用:(我错过了什么？

有任何想法吗？这一切背后的想法是通过网络服务将 nopcommerce 与我的 ERP 连接起来

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Nop.Core.Domain.Catalog
{
    public class ProductDto
    {
        public virtual string Name { get; set; }

        // Instance members must be virtual on data table objects like Affiliate.cs
        // Virtual is required by data access frameworks so that these frameworks
        // can implement more complex features like lazy loading.

        public virtual string ProductGID { get; set; }

        /// <summary>
        /// Gets or sets the short description
        /// </summary>

        public virtual string ShortDescription { get; set; }

        /// <summary>
        /// Gets or sets the full description
        /// </summary>

        public virtual string FullDescription { get; set; }

        /// <summary>
        /// Gets or sets the admin comment
        /// </summary>

        public virtual string AdminComment { get; set; }

        /// <summary>
        /// Gets or sets a value of used product template identifier
        /// </summary>

        public virtual int ProductTemplateId { get; set; }

        /// <summary>
        /// Gets or sets a value indicating whether to show the product on home page
        /// </summary>

        public virtual bool ShowOnHomePage { get; set; }

        /// <summary>
        /// Gets or sets the meta keywords
        /// </summary>

        public virtual string MetaKeywords { get; set; }

        /// <summary>
        /// Gets or sets the meta description
        /// </summary>

        public virtual string MetaDescription { get; set; }

        /// <summary>
        /// Gets or sets the meta title
        /// </summary>

        public virtual string MetaTitle { get; set; }

        /// <summary>
        /// Gets or sets the search-engine name
        /// </summary>

        public virtual string SeName { get; set; }

        /// <summary>
        /// Gets or sets a value indicating whether the product allows customer reviews
        /// </summary>

        public virtual bool AllowCustomerReviews { get; set; }

        /// <summary>
        /// Gets or sets the rating sum (approved reviews)
        /// </summary>

        public virtual int ApprovedRatingSum { get; set; }

        /// <summary>
        /// Gets or sets the rating sum (not approved reviews)
        /// </summary>

        public virtual int NotApprovedRatingSum { get; set; }

        /// <summary>
        /// Gets or sets the total rating votes (approved reviews)
        /// </summary>

        public virtual int ApprovedTotalReviews { get; set; }

        /// <summary>
        /// Gets or sets the total rating votes (not approved reviews)
        /// </summary>

        public virtual int NotApprovedTotalReviews { get; set; }

        /// <summary>
        /// Gets or sets a value indicating whether the entity is published
        /// </summary>

        public virtual bool Published { get; set; }

        /// <summary>
        /// Gets or sets a value indicating whether the entity has been deleted
        /// </summary>

        public virtual bool Deleted { get; set; }

        /// <summary>
        /// Gets or sets the date and time of product creation
        /// </summary>

        public virtual DateTime CreatedOnUtc { get; set; }

        /// <summary>
        /// Gets or sets the date and time of product update
        /// </summary>

        public virtual DateTime UpdatedOnUtc { get; set; }
    }
}

在 NopService.cs 我创建了一个这样的方法

public List<ProductDto> GetProductCollection(string usernameOrEmail, string userPassword)
    {
        CheckAccess(usernameOrEmail, userPassword);
        if (!_permissionSettings.Authorize(StandardPermissionProvider.ManageCatalog))
            throw new ApplicationException("Not allowed to manage Catalog");

        var productslist = new List<Product>();
        productslist.AddRange(_productService.GetAllProducts(false));
        List<Product> products = productslist;
        List<ProductDto> productsDtos = Mapper.Map<List<Product>, List<ProductDto>>(products);

        return productsDtos;
    }
}

Answer 1

您的映射只能在启动期间配置一次。因此，尝试将其移至个人资料：

namespace MyNamespace
{
    using System.Collections.Generic;

    using AutoMapper;

    public class ProductProfile : Profile
    {
        public override string ProfileName
        {
            get
            {
                return "ProductProfile";
            }
        }

        protected override void Configure()
        {
            Mapper.CreateMap<Product, ProductDto>();
            Mapper.CreateMap<ProductCategory, ProductCategoryDto>();
            // etc
        }
    }
}

然后在启动期间对其进行初始化（Application_Start等）：

Mapper.Initialize(m => m.AddProfile<ProductProfile>());

创建一个单元测试来检查您的映射：

namespace MyNamespace
{
    using System.Collections.Generic;

    using AutoMapper;

    using NUnit.Framework;

    [TestFixture]
    public class AutoMapperTests
    {
        [Test]
        public void AutoMapper_Configuration_IsValid()
        {
            Mapper.Initialize(m => m.AddProfile<ProductProfile>());
            Mapper.AssertConfigurationIsValid();
        }
    }
}

这将有助于确定您的映射配置中是否存在任何错误，并向您展示要修复的内容。完成此操作后，您就可以专注于使功能正常工作。

我设法让它工作，但在映射嵌套类时遇到问题。

    public virtual string Name { get; set; }

    // Instance members must be virtual on data table objects like Affiliate.cs
    // Virtual is required by data access frameworks so that these frameworks

        protected set { _productCategories = value; }
    }



}

}

产品类别类

public partial class ProductCategory : BaseEntity
{
     public virtual int ProductId { get; set; }

    /// <summary>
    /// Gets or sets the category identifier
    /// </summary>
    public virtual int CategoryId { get; set; }

     public virtual bool IsFeaturedProduct { get; set; }

     public virtual Category Category { get; set; }

    /// <summary>
    /// Gets the product
    /// </summary>
     public virtual Product Product { get; set; }

}

和 ProductCategoryDto 类

public class ProductCategoryDto

{
    /// <summary>
    /// Gets or sets the product identifier
    /// </summary>
    public virtual int ProductId { get; set; }

    /// <summary>
    /// Gets or sets the category identifier
    /// </summary>
    public virtual int CategoryId { get; set; }

    /// <summary>
    /// Gets or sets a value indicating whether the product is featured
    /// </summary>
    public virtual bool IsFeaturedProduct { get; set; }

    /// <summary>
    /// Gets or sets the display order
    /// </summary>
    public virtual int DisplayOrder { get; set; }

    /// <summary>
    /// Gets the category
    /// </summary>
    public virtual CategoryDto Category { get; set; }

    /// <summary>
    /// Gets the product
    /// </summary>
    public virtual ProductDto Product { get; set; }
}

映射是在这样的方法中完成的

public List<ProductDto> GetProductCollection(string usernameOrEmail, string userPassword)

    {
        CheckAccess(usernameOrEmail, userPassword);
        if (!_permissionSettings.Authorize(StandardPermissionProvider.ManageCatalog))
            throw new ApplicationException("Not allowed to manage Catalog");

        List<Product> productslist = new List<Product>();
        productslist.AddRange(_productService.GetAllProducts(false));
        List<ProductCategory> productCategorylist = new List<ProductCategory>();
        foreach (var product in productslist)
        {
            productCategorylist.AddRange(_categoryService.GetProductCategoriesByProductId(product.Id, false));


        }



        Mapper.CreateMap<Product, ProductDto>();

        Mapper.CreateMap<ProductCategory, ProductCategoryDto>();
        List<ProductDto> productsDto = Mapper.Map<List<Product>, List<ProductDto>>(productslist);
        List<ProductCategoryDto> productCategoriesDto = Mapper.Map<List<ProductCategory>, List<ProductCategoryDto>>(productCategorylist);


        return productsDto;

    }

问题是我从来没有得到从 ProductDto 到 ProductCategoriesDto 的 Icollection 的映射。其他一切正常。
