仓储接口实现类如下：
//PostRepository.cs using Meowv.Blog.Domain.Blog; using Meowv.Blog.Domain.Blog.Repositories; using Volo.Abp.Domain.Repositories.EntityFrameworkCore; using Volo.Abp.EntityFrameworkCore; namespace Meowv.Blog.EntityFrameworkCore.Repositories.Blog { /// <summary> /// PostRepository /// </summary> public class PostRepository : EfCoreRepository<MeowvBlogDbContext, Post, int>, IPostRepository { public PostRepository(IDbContextProvider<MeowvBlogDbContext> dbContextProvider) : base(dbContextProvider) { } } } //CategoryRepository.cs using Meowv.Blog.Domain.Blog; using Meowv.Blog.Domain.Blog.Repositories; using Volo.Abp.Domain.Repositories.EntityFrameworkCore; using Volo.Abp.EntityFrameworkCore; namespace Meowv.Blog.EntityFrameworkCore.Repositories.Blog { /// <summary> /// CategoryRepository /// </summary> public class CategoryRepository : EfCoreRepository<MeowvBlogDbContext, Category, int>, ICategoryRepository { public CategoryRepository(IDbContextProvider<MeowvBlogDbContext> dbContextProvider) : base(dbContextProvider) { } } } //TagRepository.cs using Meowv.Blog.Domain.Blog; using Meowv.Blog.Domain.Blog.Repositories; using System.Collections.Generic; using System.Threading.Tasks; using Volo.Abp.Domain.Repositories.EntityFrameworkCore; using Volo.Abp.EntityFrameworkCore; namespace Meowv.Blog.EntityFrameworkCore.Repositories.Blog { /// <summary> /// TagRepository /// </summary> public class TagRepository : EfCoreRepository<MeowvBlogDbContext, Tag, int>, ITagRepository { public TagRepository(IDbContextProvider<MeowvBlogDbContext> dbContextProvider) : base(dbContextProvider) { } /// <summary> /// 批量插入 /// </summary> /// <param></param> /// <returns></returns> public async Task BulkInsertAsync(IEnumerable<Tag> tags) { await DbContext.Set<Tag>().AddRangeAsync(tags); await DbContext.SaveChangesAsync(); } } } //PostTagRepository.cs using Meowv.Blog.Domain.Blog; using Meowv.Blog.Domain.Blog.Repositories; using System.Collections.Generic; using System.Threading.Tasks; using Volo.Abp.Domain.Repositories.EntityFrameworkCore; using Volo.Abp.EntityFrameworkCore; namespace Meowv.Blog.EntityFrameworkCore.Repositories.Blog { /// <summary> /// PostTagRepository /// </summary> public class PostTagRepository : EfCoreRepository<MeowvBlogDbContext, PostTag, int>, IPostTagRepository { public PostTagRepository(IDbContextProvider<MeowvBlogDbContext> dbContextProvider) : base(dbContextProvider) { } /// <summary> /// 批量插入 /// </summary> /// <param></param> /// <returns></returns> public async Task BulkInsertAsync(IEnumerable<PostTag> postTags) { await DbContext.Set<PostTag>().AddRangeAsync(postTags); await DbContext.SaveChangesAsync(); } } } //FriendLinkRepository.cs using Meowv.Blog.Domain.Blog; using Meowv.Blog.Domain.Blog.Repositories; using Volo.Abp.Domain.Repositories.EntityFrameworkCore; using Volo.Abp.EntityFrameworkCore; namespace Meowv.Blog.EntityFrameworkCore.Repositories.Blog { /// <summary> /// PostTagRepository /// </summary> public class FriendLinkRepository : EfCoreRepository<MeowvBlogDbContext, FriendLink, int>, IFriendLinkRepository { public FriendLinkRepository(IDbContextProvider<MeowvBlogDbContext> dbContextProvider) : base(dbContextProvider) { } } }在TagRepository和PostTagRepository仓储接口的实现中，因为数据量不大，可以直接用了EF Core自带的AddRangeAsync批量保存数据。
到这里，关于博客的自定义仓储便完成了，此时项目层级目录图，如下：
接下来在就可以在.Application服务层愉快的玩耍了，写服务之前，我们要分析我们的项目，要有哪些功能业务。由于是博客项目，无非就是一些增删改查。今天先不写博客业务，先完成对数据库文章表meowv_posts的一个简单CRUD。
在.Application层新建Blog文件夹，添加一个IBlogService.cs博客接口服务类，分别添加增删改查四个方法。
这时就要用到我们的数据传输对象(DTO)了，简单理解，DTO就是从我们的领域模型中抽离出来的对象，它是很纯粹的只包含我们拿到的数据，不参杂任何行为逻辑。
在.Application.Contracts层新建Blog文件夹，同时新建一个PostDto.cs类，与.Domain层中的Post.cs与之对应，他们很相似，但是不一样。
于是IBlogService.cs接口服务类的CRUD为：
//IBlogService.cs using Meowv.Blog.Application.Contracts.Blog; using System.Threading.Tasks; namespace Meowv.Blog.Application.Blog { public interface IBlogService { Task<bool> InsertPostAsync(PostDto dto); Task<bool> DeletePostAsync(int id); Task<bool> UpdatePostAsync(int id, PostDto dto); Task<PostDto> GetPostAsync(int id); } }接口写好了，少不了实现方式，直接在Blog文件夹新建Impl文件夹，用来存放我们的接口实现类BlogService.cs，注意：都是以Service结尾的噢~
