ABP架構學習系列四：集成Dapper

　　以前，一直想集成Dapper到項目中，可是一直沒成功，今天把abp升級到最新版，而後按教程來，就能夠了，呵呵

　   如今，基於上一篇的源碼進行升級和集成dapper，將abp升級到3.8.2

　  官方升級文檔：https://github.com/ABPFrameWorkGroup/AbpDocument2Chinese/blob/master/Markdown/Abp/9.5ABP%E5%9F%BA%E7%A1%80%E8%AE%BE%E6%96%BD%E5%B1%82-%E9%9B%86%E6%88%90Dapper.md

1、註冊Module

　　首先，你要在Module類上添加 DependsOn 特性，而且使用 AbpDapperModule 做爲傳入參數。依賴關係的前後順序 AbpDapperModule 依賴應該在 EF Core依賴以後。

　　修改ZmBlog.Infrastructure的ZmBlogDataModule 以下：

namespace ZmBlog.EntityFramework
{
    [DependsOn(typeof(ZmBlogCoreModule), typeof(AbpEntityFrameworkModule), typeof(AbpDapperModule))]
    public class ZmBlogDataModule : AbpModule
    {
        public override void PreInitialize()
        {
            Database.SetInitializer(new CreateDatabaseIfNotExists<ZmBlogDbContext>());

            Configuration.DefaultNameOrConnectionString = "DefaultConnection";
        }

        public override void Initialize()
        {
            IocManager.RegisterAssemblyByConvention(Assembly.GetExecutingAssembly());

            DapperExtensions.DapperExtensions.SetMappingAssemblies(new List<Assembly> { typeof(ZmBlogDataModule).GetAssembly() });
        }
    }
}

2、配置實體與表的映射

　　和ef同樣，須要配置映射關係

public class PersonMapper : ClassMapper<Category>
    {
        public PersonMapper()
        {
            Table("Categories");
            AutoMap();
        }
    }

PS: 若是同時使用ef，它的映射最好使用ToTable指定表名，否則ef會自動轉換最後一個單詞爲複數

 

3、使用

　　1.在應用層使用

　　　　 private readonly IRepository<Category, string> _categoryRepository; 
        private readonly IDapperRepository<Category, string> _categoryDapperRepository; 
        private readonly ICategoryDapperRepository _categoryDapperRepo; 
 

        public CategoryApp(IRepository<Category, string> categoryRepository, IDapperRepository<Category, string> categoryDapperRepository, ICategoryDapperRepository categoryDapperRepository2)
        {
            _categoryRepository = categoryRepository;
            _categoryDapperRepository = categoryDapperRepository;
            _categoryDapperRepo = categoryDapperRepository2;
        }

　　2.DapperRepository的封裝

　　封裝的倉儲基類

namespace ZmBlog.EntityFramework.EntityFramework.DapperRepositories
{
    public abstract class DapperRepository<TEntity, TPrimaryKey> : DapperEfRepositoryBase<ZmBlogDbContext, TEntity, TPrimaryKey> where TEntity : class, IEntity<TPrimaryKey>
    {
        public DapperRepository(IActiveTransactionProvider activeTransactionProvider) : base(activeTransactionProvider)
        {
        }
    }

    public abstract class DapperRepository<TEntity> : DapperEfRepositoryBase<ZmBlogDbContext, TEntity, string> where TEntity : class, IEntity<string>
    {
        public DapperRepository(IActiveTransactionProvider activeTransactionProvider) : base(activeTransactionProvider)
        {
        }
    }
}

　　定義倉儲接口和實現

//領域層
public interface ICategoryDapperRepository : IDapperRepository<Category, string>
    {
    }
//基礎設施層
public class CategoryDapperRepository : DapperRepository<Category, string>, ICategoryDapperRepository
    {
        public CategoryDapperRepository(IActiveTransactionProvider activeTransactionProvider) : base(activeTransactionProvider)
        {
        }
    }
