DDD架构项目依赖关系图 调整后架构图，Domain对象转Dto对象可以使用AotoMap

4.基础设施层构建 EntityFramewrokCore 层构建 1.创建EntityFrameworkCore项目 2.引用 Volo.Abp.AspNetCore //ABP核心 Volo.Abp.EntityFrameworkCore //EFCore支持性 3.创建Module文件 继承AbpModule,依赖AbpEntityFrameworkCoreModule [DependsOn(typeof(Volo.Abp.EntityFrameworkCore.AbpEntityFrameworkCoreModule))] public class AbpEntityFrameworkCoreModule:AbpModule { } 4.创建数据库Context上下文类继承AbpDbContext public class AbpEntityDBContext : AbpDbContext<AbpEntityDBContext> { public AbpEntityDBContext(DbContextOptions<AbpEntityDBContext> options) : base(options) { } protected override void OnModelCreating(ModelBuilder modelBuilder) { base.OnModelCreating(modelBuilder); } } 5.EntityFramewrokCore模块里面注入DbContext [DependsOn(typeof(Volo.Abp.EntityFrameworkCore.AbpEntityFrameworkCoreModule))] public class AbpEntityFrameworkCoreModule:AbpModule { public override void ConfigureServices(ServiceConfigurationContext context) { //注入DB context.Services.AddAbpDbContext<AbpEntityDBContext>(); //使用sqlserver数据库 Configure<AbpDbContextOptions>(opt => opt.UseSqlServer()); } } 6.在Web主程序appsettings.json里面配置连接字符串 7.在数据库上下文类加入特性 [ConnectionStringName("Default")] 完成连接字符串配置 8.配置主模块加入依赖 typeof(AbpDemoEntityFrameworkCoreModule)

3.依赖注入 模块之间的引用是通过依赖注入

2.模块化开发 Abp每一个项目都是模块，按模块开发，模块依赖型的 [DependsOn] (依赖) Abp的核心就是模块依赖 namespace AbpDemo { [DependsOn(typeof(AbpAspNetCoreMvcModule))] public class AbpDemoModule:AbpModule { /// <summary> /// 服务依赖注入 /// </summary> /// <param name="context"></param> public override void ConfigureServices(ServiceConfigurationContext context) { base.ConfigureServices(context); } /// <summary> /// 中间件配置 /// </summary> /// <param name="context"></param> public override void OnApplicationInitialization(ApplicationInitializationContext context) { base.OnApplicationInitialization(context); } } } 2.把启动类里面的依赖注入builder.Services.XXX转移到模块类的ConfigureServices 3.把启动类的app.UseXXX使用中间件等代码转移到OnApplicationInitialization 调整完后Program.cs启动类变成 using AbpDemo; var builder = WebApplication.CreateBuilder(args); // 重新注册 Configuration 不加启动会报错 builder.Services.ReplaceConfiguration(builder.Configuration); //添加自定义模块 builder.Services.AddApplication<AbpDemoModule>(); //* 同上等效代码 //* 添加自定义模块 DemoWebApiModule //builder.Services.AddApplication<DemoWebApiModule>(options => { //options.Services.ReplaceConfiguration(builder.Configuration); // 重新注册 Configuration //}); var app = builder.Build(); app.InitializeApplication(); app.Run(); Module类： using Volo.Abp; using Volo.Abp.AspNetCore.Mvc; using Volo.Abp.Modularity; namespace AbpDemo { [DependsOn( typeof(AbpAspNetCoreMvcModule), typeof(AbpAutofacModule) )] public class AbpDemoModule : AbpModule { /// <summary> /// 服务依赖注入 /// </summary> /// <param name="context"></param> public override void ConfigureServices(ServiceConfigurationContext context) { context.Services.AddControllersWithViews(); } /// <summary> /// 中间件配置 /// </summary> /// <param name="context"></param> public override void OnApplicationInitialization(ApplicationInitializationContext context) { var app = context.GetApplicationBuilder(); if (!context.GetEnvironment().IsDevelopment()) { app.UseExceptionHandler("/Home/Error"); } app.UseStaticFiles(); app.UseRouting(); app.UseAuthorization(); app.UseEndpoints( end => { end.MapControllerRoute( name: "default", pattern: "{controller=Home}/{action=Index}/{id?}" ); } ); } } } 项目启动即可

5.领域(Domain)层构建 1.领域层放数据库对应的实体 引入 Volo.Abp.AspNetCore, Volo.Abp.Ddd.Domain [DependsOn( typeof(AbpDddDomainModule) //依赖领域模块 )] public class AbpDemoDomainModule:AbpModule { }
