  上篇文章已经封装好了类库,现在继续实现功能,在ABPZero框架的基础上来实现一个完整的功能。

Redis缓存

编写功能前先在本机安装好Redis,需要用到Redis做缓存,以下分享2个Windows安装Redis的教程

博客园:http://www.cnblogs.com/mzws/p/redis1.html

我的笔记:http://note.youdao.com/noteshare?id=a25fc319c5a38285ab7cab2e81857b31&sub=675165188B214E6CA0660B8EEB0A1C35(请记得及时收藏,可能不知哪天就失效了)

Core项目

在Core项目下新建Pdd目录,继续在Pdd目录下新建Entities、IRepositories目录,建完如下图所示:

 

接着在Entities目录下新建PddMall实体类,代码如下:

/// <summary>
    /// 店铺
    /// </summary>
    public class PddMall : FullAuditedEntity
    {
        /// <summary>
        /// 店铺id
        /// </summary>
        public string MallId { get; set; }

        /// <summary>
        /// 店铺名称
        /// </summary>
        public string Name { get; set; }

        /// <summary>
        /// logo
        /// </summary>
        public string Logo { get; set; }

        /// <summary>
        /// 描述
        /// </summary>
        public string Desc { get; set; }

        /// <summary>
        /// 退款地址
        /// </summary>
        public string RefundAddress { get; set; }

        /// <summary>
        /// 销售量
        /// </summary>
        public long Sales { get; set; }

        /// <summary>
        /// 商品数量
        /// </summary>
        public int GoodNum { get; set; }
    }

 

继续在IRepositories目录下新建IMallRepository仓储接口,代码如下:

public interface IMallRepository : IRepository<PddMall>
{
}

 

EntityFramework项目

打开AbpZeroTemplateDbContext.cs文件,添加如下代码:

文件路径:D:\abpweb\PddSellerAssistant\PddSellerAssistant.EntityFramework\EntityFramework\AbpZeroTemplateDbContext.cs

/************拼多多相关*********************************/
public virtual IDbSet<PddMall> PddMalls { get; set; }
/************拼多多相关*********************************/

打开VS的包管理控制台,并在包管理控制台中选择 .EntityFramework 项目作为默认项目。然后在控制台中执行下面命令:

Add-Migration "Add_PddMall"

 

看到上图黄色提示说明创建迁移文件成功

同时Migrations目录多了一个文件,这个就是刚刚创建的迁移文件。

现在你可以使用下面命令来创建数据库:

Update-Database

 

命令执行成功,查看数据库也创建了对应的表(如下):

 

再EntityFramework项目下新建Pdd目录,接着再创建Repositories目录,结构如下:

Repositories目录下新建MallRepository仓储实现类,代码如下:

public class MallRepository : AbpZeroTemplateRepositoryBase<PddMall>, IMallRepository
    {
        public MallRepository(IDbContextProvider<AbpZeroTemplateDbContext> dbContextProvider) : base(dbContextProvider)
        {
        }
    }

 

 

Application项目

首先引用类库PddTool

 

同样新建Pdd目录,此目录下再新建MallApp、ProductApp,这两个目录分别再创建Dto目录,效果如下:

 

MallApp目录下新建IMallAppService接口,代码如下:

public interface IMallAppService : IApplicationService
    {
        void CreateByMallId(CreateMallInput input);
        /// <summary>
        /// 获取店铺信息,返回店铺编号、店铺名称
        /// 
        /// </summary>
        /// <returns></returns>
        MallOutput GetMallInfo(int id);

        /// <summary>
        /// 获取店铺列表
        /// </summary>
        /// <returns></returns>
        GetMallsOutput GetMalls();

        
    }

 

 

此时,Input、Output类会报错,接着在Dto目录下再创建这几个类,分别如下:

public class CreateMallInput
    {
        [Required]
        public string MallId { get; set; }
    }

 

 

public class MallOutput
    {
        public int Id { get; set; }

        /// <summary>
        /// 店铺名称
        /// </summary>
        public string Name { get; set; }

        /// <summary>
        /// 店铺id
        /// </summary>
        public string MallId { get; set; }
    }

 

 

public class GetMallsOutput
    {
        public List<MallOutput> Items { get; set; }
    }

 

 

MallApp目录下再新建MallAppService类,代码如下:

public class MallAppService : AbpZeroTemplateAppServiceBase, IMallAppService
    {
        private readonly IMallRepository _mallRepository;
        private readonly ICacheManager _cacheManager;
        public MallAppService(IMallRepository mallRepository, ICacheManager cacheManager)
        {
            _mallRepository = mallRepository;
            _cacheManager = cacheManager;
        }

        /// <summary>
        /// 获取店铺信息
        /// </summary>
        /// <param name="id"></param>
        /// <returns></returns>
        public MallOutput GetMallInfo(int id)
        {

            var mall = _mallRepository.Get(id);
            return new MallOutput()
            {
                Id = mall.Id,
                MallId = mall.MallId,
                Name = mall.Name
            };
        }

        /// <summary>
        /// 添加店铺
        /// </summary>
        /// <param name="input"></param>
        public void CreateByMallId(CreateMallInput input)
        {
            try
            {
                var mall = MallTool.GetInfo(input.MallId);
                var entity = new PddMall()
                {
                    Name = mall.mall_name,
                    Desc = mall.mall_desc,
                    GoodNum = mall.goods_num,
                    Logo = mall.logo,
                    MallId = input.MallId,
                    RefundAddress = mall.refund_address,
                    Sales = mall.mall_sales,
                };
                //按店铺id查询店铺资料
                var count = _mallRepository.Count(a => a.MallId.Equals(input.MallId) && a.CreatorUserId == AbpSession.UserId);
                if (count != 0)
                {
                    //数据库存在则更新
                    var m = _mallRepository.Single(a => a.MallId.Equals(input.MallId) && a.CreatorUserId == AbpSession.UserId);
                    m.Name = entity.Name;
                    m.Desc = entity.Desc;
                    m.GoodNum = entity.GoodNum;
                    m.Logo = entity.Logo;
                    m.MallId = entity.MallId;
                    m.RefundAddress = entity.RefundAddress;
                    m.Sales = entity.Sales;
                    _mallRepository.Update(m);
                }
                else
                {
                    //数据库不存在此店铺则使用API获取
                    _mallRepository.Insert(entity);
                }

            }
            catch (Exception ex)
            {
                throw new UserFriendlyException(ex.Message);
            }
        }

        /// <summary>
        /// 从数据库中获取店铺列表
        /// </summary>
        /// <returns></returns>
        public GetMallsOutput GetMalls()
        {
            var list = _mallRepository.GetAllList(a => a.CreatorUserId == AbpSession.UserId);
            //创建映射
            return new GetMallsOutput()
            {
                Items = Mapper.Map<List<MallOutput>>(list)
            };
        }
        
    }

 

 

目录结构如下:

 

ProductApp目录下继续新建IProductAppService接口,代码如下:

public interface IProductAppService : IApplicationService
    {
        
        Task<PagedResultDto<KaiTuanProductOutput>> GetKaiTuanProductsAsync(GetProductsInput input);

        /// <summary>
        /// 根据商品id获取此商品所有拼团信息
        /// </summary>
        /// <param name="input"></param>
        /// <returns></returns>
        //[HttpGet]
        PagedResultDto<ProductOutput> GetAllKaiTuansByGoodId(GetAllKaiTuansInput input);
    }

 

 

接着再新建ProductAppService类,代码如下:

public class ProductAppService : AbpZeroTemplateAppServiceBase, IProductAppService
    {
        /// <summary>
        /// 缓存管理
        /// </summary>
        private readonly ICacheManager _cacheManager;
        private string key;    //缓存key
        public ProductAppService(ICacheManager cacheManager)
        {
            _cacheManager = cacheManager;
        }
        /// <summary>
        ///根据店铺id, 获取有开团的商品
        /// </summary>
        /// <param name="input"></param>
        /// <returns></returns>
        public async Task<PagedResultDto<KaiTuanProductOutput>> GetKaiTuanProductsAsync(GetProductsInput input)
        {
            //获取所有商品的开团人数
            var list = MallTool.GetKaiTuanList(input.MallId);
            //清除缓存
            key = string.Format("{0}_{1}_KaiTuan", AbpSession.UserId, input.MallId);
            _cacheManager.GetCache(key).Clear();
            #region 数据转换
            var items = new List<KaiTuanProductOutput>();
            foreach (var localGroupItem in list)
            {
                var item = new KaiTuanProductOutput()
                {
                    GoodId = localGroupItem.GoodId,
                    Name = localGroupItem.Name,
                    KaiTuanCount = localGroupItem.KaiTuanCount,
                    Img = localGroupItem.Img,

                };
                items.Add(item);
            }
            #endregion
            int totalCount = list.Count;

            #region 处理排序
            if (input.Sorting.Equals("goodId ASC"))
            {
                items = items.OrderBy(a => a.GoodId).ToList();
            }
            else if (input.Sorting.Equals("goodId DESC"))
            {
                items = items.OrderByDescending(a => a.GoodId).ToList();
            }
            if (input.Sorting.Equals("name ASC"))
            {
                items = items.OrderBy(a => a.Name).ToList();
            }
            else if (input.Sorting.Equals("name DESC"))
            {
                items = items.OrderByDescending(a => a.Name).ToList();
            }
            if (input.Sorting.Equals("kaiTuanCount ASC"))
            {
                items = items.OrderBy(a => a.KaiTuanCount).ToList();
            }
            else if (input.Sorting.Equals("kaiTuanCount DESC"))
            {
                items = items.OrderByDescending(a => a.KaiTuanCount).ToList();
            }
            #endregion

            return new PagedResultDto<KaiTuanProductOutput>(totalCount, items);
        }

        /// <summary>
        /// 根据商品id,获取此商品所有开团
        /// </summary>
        /// <param name="input"></param>
        /// <returns></returns>
        public PagedResultDto<ProductOutput> GetAllKaiTuansByGoodId(GetAllKaiTuansInput input)
        {
            #region 使用redis缓存
            key = string.Format("{0}_{1}_KaiTuan", AbpSession.UserId, input.MallId);
            var list = _cacheManager.GetCache<string, List<KaiTuan>>(key).Get("GetAllKaiTuanByGoodId." + input.GoodId, () => MallTool.GetAllKaiTuanByGoodId(input.MallId, input.GoodId));

            #endregion
            #region 数据转换
            List<ProductOutput> productOutputs = Mapper.Map<List<ProductOutput>>(list);

            #endregion
            #region 处理排序
            if (input.Sorting.Equals("timeLeft ASC"))
            {
                productOutputs = productOutputs.OrderBy(a => a.TimeLeft).ToList();
            }
            else if (input.Sorting.Equals("timeLeft DESC"))
            {
                productOutputs = productOutputs.OrderByDescending(a => a.TimeLeft).ToList();
            }
            #endregion

            int total = productOutputs.Count;
            #region 处理分页
            productOutputs = productOutputs.Skip(input.SkipCount).Take(input.MaxResultCount).ToList();
            #endregion
            return new PagedResultDto<ProductOutput>(total, productOutputs);
        }
    }

 

同样Input、Output报错,在Dto分别创建如下类即可:

public class KaiTuanProductOutput
    {
        public int Id { get; set; }

        public int GoodId { get; set; }

        /// <summary>
        /// 商品名称
        /// </summary>
        public string Name { get; set; }

        /// <summary>
        /// 商品图片
        /// </summary>
        public string Img { get; set; }

        /// <summary>
        /// 开团人数
        /// </summary>
        public int KaiTuanCount { get; set; }
    }

 

 

public class GetProductsInput : PagedAndSortedInputDto, IShouldNormalize
    {
        /// <summary>
        /// 店铺id
        /// </summary>
        public string MallId { get; set; }

        /// <summary>
        /// 提醒间隔(分钟)
        /// </summary>
        public int Interval { get; set; }
        public void Normalize()
        {
            if (string.IsNullOrEmpty(Sorting))
            {
                Sorting = "Name";
            }
        }
    }

 

 

public class ProductOutput
    {
        /// <summary>
        /// 商品id
        /// </summary>
        public int Id { get; set; }

        /// <summary>
        /// 昵称
        /// </summary>
        public string  NickName { get; set; }

        /// <summary>
        /// 
        /// </summary>
        public string SKU { get; set; }

        /// <summary>
        /// 订单号
        /// </summary>
        public string OrderNum { get; set; }

        /// <summary>
        /// 剩余时间
        /// </summary>
        public double TimeLeft { get; set; }

        /// <summary>
        /// 开团单号
        /// </summary>
        public string KaiTuanOrderNum { get; set; }
    }

 

 

public class GetAllKaiTuansInput : PagedAndSortedInputDto, IShouldNormalize
    {
        /// <summary>
        /// 店铺id
        /// </summary>
        public int MallId { get; set; }
        /// <summary>
        /// 商品id
        /// </summary>
        public int GoodId { get; set; }

public void Normalize() { if (string.IsNullOrEmpty(Sorting)) { Sorting = "timeLeft ASC"; } } }

 

 

再打开CustomDtoMapper.cs,添加如下代码(约定映射):

文件路径:D:\abp version\aspnet-zero-3.4.0\aspnet-zero-3.4.0\src\MyCompanyName.AbpZeroTemplate.Application\CustomDtoMapper.cs

private static void CreateMappingsInternal(IMapperConfigurationExpression mapper)
        {
            mapper.CreateMap<User, UserEditDto>()
                .ForMember(dto => dto.Password, options => options.Ignore())
                .ReverseMap()
                .ForMember(user => user.Password, options => options.Ignore());
            /**********************拼多多相关********************************/
            mapper.CreateMap<PddMall, MallOutput>();
            mapper.CreateMap<KaiTuan, ProductOutput>();
        }

 

 

以上整个拼团提醒业务逻辑就完成了,最终Application项目中Pdd目录结构如下:

 

生成解决方案,浏览器打开框架后台登录。

浏览器再打开http://localhost:8088/swagger/ui/index,进行api测试。

按上一篇提到获取拼多多店铺编号的方法,找一个店铺编号:1227314,对刚刚编写的功能进行测试。

目前只有店铺资料会保存到数据库,商品信息或拼团信息保存到缓存。

本篇内容比较多,页面实现移到下一篇。

 

 返回总目录
