ABP架构学习系列四:集成Dapper
之前,一直想集成Dapper到项目中,但是一直没成功,今天把abp升级到最新版,然后按教程来,就可以了,呵呵
现在,基于上一篇的源码进行升级和集成dapper,将abp升级到3.8.2
官方升级文档: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
一、注册Module
首先,你要在Module类上添加 DependsOn 特性,并且使用 AbpDapperModule 作为传入参数。依赖关系的先后顺序 AbpDapperModule 依赖应该在 EF Core依赖之后。
修改ZmBlog.Infrastructure的ZmBlogDataModule 如下:
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() }); } } }
二、配置实体与表的映射
和ef一样,需要配置映射关系
public class PersonMapper : ClassMapper<Category> { public PersonMapper() { Table("Categories"); AutoMap(); } }
PS: 如果同时使用ef,它的映射最好使用ToTable指定表名,不然ef会自动转换最后一个单词为复数
三、使用
1.在应用层使用
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的封装
封装的仓储基类
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) { } } }
定义仓储接口和实现
//领域层 public interface ICategoryDapperRepository : IDapperRepository<Category, string> { } //基础设施层 public class CategoryDapperRepository : DapperRepository<Category, string>, ICategoryDapperRepository { public CategoryDapperRepository(IActiveTransactionProvider activeTransactionProvider) : base(activeTransactionProvider) { } }
