官方文檔:https://docs.abp.io/程序員
ABP CLI是使用ABP框架啓動新解決方案的最快方法。若是沒有安裝ABP CLI,使用命令行窗口安裝ABP CLI:github
dotnet tool install -g Volo.Abp.Cli
abp new Acme.BookStore
您可使用不一樣級別的名稱空間。例如BookStore,Acme.BookStore或Acme.Retail.BookStore。web
這樣,就已經完成了一個應用程序的搭建。
sql
而後咱們只須要修改一下其餘的配置便可運行應用程序,開發人員在這個架構的基礎上就能夠愉快的擼代碼了。數據庫
然而,ABP的學習纔剛剛開始。ABP放棄了原有MVC的架構,使用了模塊化架構,支持微服務,根據DDD模式和原則設計和開發,爲應用程序提供分層模型。對於沒有微服務開發經驗的程序員來講,學習ABP難度比較大。下面咱們開始從一個空的web解決方案,一步步搭建API接口服務。json
開發環境:Mac Visual Studio Code
SDK:dotnet core 3.1api
使用命令建立一個空的web方案:緩存
dotnet new web -o Lemon.UserCenter.HttpApi.Hosting
建立api層 dotnet new classlib -o Lemon.UserCenter.HttpApi 建立應用層 dotnet new classlib -o Lemon.UserCenter.Application 建立領域層 dotnet new classlib -o Lemon.UserCenter.Domain 建立基於EntityFrameworkCore的數據層 dotnet new classlib -o Lemon.UserCenter.EntityFrameworkCore
建立解決方案 dotnet new sln 全部類庫加入解決方案 dotnet sln Lemon.UserCenter.sln add Lemon.UserCenter.HttpApi.Hosting/Lemon.UserCenter.HttpApi.Hosting.csproj dotnet sln Lemon.UserCenter.sln add Lemon.UserCenter.HttpApi/Lemon.UserCenter.HttpApi.csproj dotnet sln Lemon.UserCenter.sln add Lemon.UserCenter.Application/Lemon.UserCenter.Application.csproj dotnet sln Lemon.UserCenter.sln add Lemon.UserCenter.Domain/Lemon.UserCenter.Domain.csproj dotnet sln Lemon.UserCenter.sln add Lemon.UserCenter.EntityFrameworkCore/Lemon.UserCenter.EntityFrameworkCore.csproj 添加項目引用 dotnet add Lemon.UserCenter.HttpApi.Hosting/Lemon.UserCenter.HttpApi.Hosting.csproj reference Lemon.UserCenter.HttpApi/Lemon.UserCenter.HttpApi.csproj dotnet add Lemon.UserCenter.HttpApi.Hosting/Lemon.UserCenter.HttpApi.Hosting.csproj reference Lemon.UserCenter.EntityFrameworkCore/Lemon.UserCenter.EntityFrameworkCore.csproj dotnet add Lemon.UserCenter.HttpApi/Lemon.UserCenter.HttpApi.csproj reference Lemon.UserCenter.Application/Lemon.UserCenter.Application.csproj dotnet add Lemon.UserCenter.Application/Lemon.UserCenter.Application.csproj reference Lemon.UserCenter.Domain/Lemon.UserCenter.Domain.csproj dotnet add Lemon.UserCenter.EntityFrameworkCore/Lemon.UserCenter.EntityFrameworkCore.csproj reference Lemon.UserCenter.Domain/Lemon.UserCenter.Domain.csproj
領域層添加Volo.Abp.Identity.Domain包引用:架構
dotnet add Lemon.UserCenter.Domain/Lemon.UserCenter.Domain.csproj package Volo.Abp.Identity.Domain
建立領域層模塊類:
using Volo.Abp.Identity; using Volo.Abp.Modularity; namespace Lemon.UserCenter.Domain { [DependsOn(typeof(AbpIdentityDomainModule))] public class UserCenterDomainModule : AbpModule { } }
建立實體類:
using System; using Volo.Abp.Domain.Entities; namespace Lemon.UserCenter.Domain { public class UserData : Entity<Guid> { /// <summary> /// 帳號 /// </summary> /// <value>The account.</value> public string Account { get; set; } /// <summary> /// 暱稱 /// </summary> /// <value>The name of the nike.</value> public string NickName { get; set; } = ""; /// <summary> /// 頭像 /// </summary> /// <value>The head icon.</value> public string HeadIcon { get; set; } = ""; /// <summary> /// 手機號碼 /// </summary> /// <value>The mobile.</value> public string Mobile { get; set; } = ""; /// <summary> /// 電子郵箱 /// </summary> /// <value>The email.</value> public string Email { get; set; } = ""; /// <summary> /// 刪除註記 /// </summary> /// <value><c>true</c> if deleted; otherwise, <c>false</c>.</value> public bool Deleted { get; set; } } }
數據層添加引用:
dotnet add Lemon.UserCenter.EntityFrameworkCore/Lemon.UserCenter.EntityFrameworkCore.csproj package Volo.Abp.EntityFrameworkCore dotnet add Lemon.UserCenter.EntityFrameworkCore/Lemon.UserCenter.EntityFrameworkCore.csproj package Volo.Abp.EntityFrameworkCore.PostgreSQL dotnet add Lemon.UserCenter.EntityFrameworkCore/Lemon.UserCenter.EntityFrameworkCore.csproj package Microsoft.EntityFrameworkCore.Design dotnet add Lemon.UserCenter.EntityFrameworkCore/Lemon.UserCenter.EntityFrameworkCore.csproj package Microsoft.EntityFrameworkCore dotnet add Lemon.UserCenter.EntityFrameworkCore/Lemon.UserCenter.EntityFrameworkCore.csproj package Microsoft.EntityFrameworkCore.Relational
在這裏咱們使用的是PostgreSQL數據庫,因此引用了Volo.Abp.EntityFrameworkCore.PostgreSQL,若是使用的是MySQL,就要引用Volo.Abp.EntityFrameworkCore.MySQL,若是使用的是sqlserver,就要引用Volo.Abp.EntityFrameworkCore.SQLServer。
加入UserCenterDbContext類:
using Lemon.UserCenter.Domain; using Microsoft.EntityFrameworkCore; using Volo.Abp.Data; using Volo.Abp.EntityFrameworkCore; namespace Lemon.UserCenter.EntityFrameworkCore { [ConnectionStringName("Default")] public class UserCenterDbContext : AbpDbContext<UserCenterDbContext> { public DbSet<UserData> UserData { get; set; } public UserCenterDbContext(DbContextOptions<UserCenterDbContext> options) : base(options) { } protected override void OnModelCreating(ModelBuilder builder) { base.OnModelCreating(builder); } } }
加入UserCenterDbContextFactory類:
using System.IO; using Microsoft.EntityFrameworkCore; using Microsoft.EntityFrameworkCore.Design; using Microsoft.Extensions.Configuration; namespace Lemon.UserCenter.EntityFrameworkCore { public class UserCenterDbContextFactory: IDesignTimeDbContextFactory<UserCenterDbContext> { public UserCenterDbContext CreateDbContext(string[] args) { var configuration = BuildConfiguration(); var builder = new DbContextOptionsBuilder<UserCenterDbContext>() .UseNpgsql(configuration.GetConnectionString("Default")); return new UserCenterDbContext(builder.Options); } private static IConfigurationRoot BuildConfiguration() { var builder = new ConfigurationBuilder() .SetBasePath(Directory.GetCurrentDirectory()) .AddJsonFile("appsettings.json", optional: false); return builder.Build(); } } }
加入appsettings.json配置,用於生成數據遷移代碼:
{ "ConnectionStrings": { "Default": "server=127.0.0.1;port=5432;Database=abp-samples-user-center;uid=postgres;pwd=123456" } }
建立數據層模塊類:
using Lemon.UserCenter.Domain; using Microsoft.EntityFrameworkCore; using Microsoft.Extensions.DependencyInjection; using Volo.Abp.EntityFrameworkCore; using Volo.Abp.EntityFrameworkCore.PostgreSql; using Volo.Abp.Modularity; namespace Lemon.UserCenter.EntityFrameworkCore { [DependsOn(typeof(UserCenterDomainModule), typeof(AbpEntityFrameworkCoreModule), typeof(AbpEntityFrameworkCorePostgreSqlModule))] public class UserCenterentityFrameworkCoreModule : AbpModule { public override void ConfigureServices(ServiceConfigurationContext context) { context.Services.AddAbpDbContext<UserCenterDbContext>(options => { options.AddDefaultRepositories(includeAllEntities: true); }); Configure<AbpDbContextOptions>(options => { options.Configure(ctx => { if (ctx.ExistingConnection != null) { ctx.DbContextOptions.UseNpgsql(ctx.ExistingConnection); } else { ctx.DbContextOptions.UseNpgsql(ctx.ConnectionString); } }); }); #region 自動遷移數據庫 context.Services.BuildServiceProvider().GetService<UserCenterDbContext>().Database.Migrate(); #endregion 自動遷移數據庫 } } }
生成數據遷移代碼:
dotnet ef migrations add InitialCreate --project Lemon.UserCenter.EntityFrameworkCore/Lemon.UserCenter.EntityFrameworkCore.csproj
在數據層下生成一個Migrations文件夾,裏面的代碼就是數據遷移代碼,執行如下命令便可在數據庫中自動生成數據庫表:
dotnet ef database update --project Lemon.UserCenter.EntityFrameworkCore/Lemon.UserCenter.EntityFrameworkCore.csproj
應用層添加Volo.Abp.Identity.Application應用:
dotnet add Lemon.UserCenter.Application/Lemon.UserCenter.Application.csproj package Volo.Abp.Identity.Application
建立應用層模塊類:
using Volo.Abp.Modularity; using Volo.Abp.Identity; namespace Lemon.UserCenter.Application { [DependsOn(typeof(AbpIdentityApplicationModule))] public class UserCenterApplicationModule : AbpModule { } }
建立用戶接口:
using System.Threading.Tasks; using Lemon.UserCenter.Domain; namespace Lemon.UserCenter.Application { public interface IUserService { Task<UserData> Create(UserData data); } }
實現用戶服務:
using System; using System.Threading.Tasks; using Lemon.UserCenter.Domain; using Volo.Abp.Application.Services; using Volo.Abp.Domain.Repositories; namespace Lemon.UserCenter.Application { public class UserService : ApplicationService, IUserService { private readonly IRepository<UserData, Guid> _repository; public UserService(IRepository<UserData, Guid> repository) { this._repository = repository; } public async Task<UserData> Create(UserData data) { return await _repository.InsertAsync(data); } } }
api層添加Volo.Abp.Identity.HttpApi引用:
dotnet add Lemon.UserCenter.HttpApi/Lemon.UserCenter.HttpApi.csproj package Volo.Abp.Identity.HttpApi
建立模塊類:
using Lemon.UserCenter.Application; using Volo.Abp.Identity; using Volo.Abp.Modularity; namespace Lemon.UserCenter.HttpApi { [DependsOn(typeof(AbpIdentityHttpApiModule), typeof(UserCenterApplicationModule))] public class UserCenterHttpApiModule : AbpModule { } }
建立controller:
using System.Threading.Tasks; using Lemon.UserCenter.Application; using Lemon.UserCenter.Domain; using Microsoft.AspNetCore.Mvc; using Volo.Abp.AspNetCore.Mvc; namespace Lemon.UserCenter.HttpApi.Controllers { [Route("api/user")] public class UserController : AbpController { private readonly IUserService _userService; public UserController(IUserService userService) { this._userService = userService; } [HttpPost("create")] public async Task<IActionResult> Create(UserData data) { var result = await _userService.Create(data); return Json(result); } } }
添加Volo.Abp.Autofac引用:
dotnet add Lemon.UserCenter.HttpApi.Hosting/Lemon.UserCenter.HttpApi.Hosting.csproj package Volo.Abp.Autofac
建立模塊類
using Lemon.UserCenter.Domain; using Lemon.UserCenter.EntityFrameworkCore; using Microsoft.AspNetCore.Builder; using Microsoft.Extensions.Hosting; using Volo.Abp; using Volo.Abp.AspNetCore.Mvc; using Volo.Abp.Autofac; using Volo.Abp.Modularity; namespace Lemon.UserCenter.HttpApi.Hosting { [DependsOn(typeof(UserCenterHttpApiModule), typeof(UserCenterDomainModule), typeof(UserCenterentityFrameworkCoreModule), typeof(AbpAspNetCoreMvcModule), typeof(AbpAutofacModule))] public class UserCenterHttpApiHostingModule: AbpModule { public override void OnApplicationInitialization( ApplicationInitializationContext context) { var app = context.GetApplicationBuilder(); var env = context.GetEnvironment(); if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } else { app.UseExceptionHandler("/Error"); } app.UseStaticFiles(); app.UseRouting(); app.UseMvcWithDefaultRouteAndArea(); } } }
修改Program類,新增UseAutofac:
using Microsoft.AspNetCore.Hosting; using Microsoft.Extensions.Hosting; namespace Lemon.UserCenter.HttpApi.Hosting { public class Program { public static void Main(string[] args) { CreateHostBuilder(args).Build().Run(); } public static IHostBuilder CreateHostBuilder(string[] args) => Host.CreateDefaultBuilder(args) .ConfigureWebHostDefaults(webBuilder => { webBuilder.UseStartup<Startup>(); }).UseAutofac(); } }
修改Startup類:
using Microsoft.AspNetCore.Builder; using Microsoft.Extensions.DependencyInjection; namespace Lemon.UserCenter.HttpApi.Hosting { public class Startup { public void ConfigureServices(IServiceCollection services) { services.AddApplication<UserCenterHttpApiHostingModule>(); } public void Configure(IApplicationBuilder app) { app.InitializeApplication(); } } }
cd Lemon.UserCenter.HttpApi.Hosting dotnet watch run
操做以下圖:
數據庫結果以下:
以上就是接口服務的構建過程,主要參考了ABP CLI生成的項目結構,可是又有所不一樣。整個分層架構還能夠繼續優化,這個就見仁見智吧。後續還會繼續分享ABP的相關知識,例如identity server 四、緩存、微服務等。
