建立API專案
建立API專案並安裝以下依賴
修改Program.cs為以下內容
using BookApp;
var builder = WebApplication.CreateBuilder(args);
await builder.AddApplicationAsync<BookAbpModule>();
builder.Host.UseAutofac();
var app = builder.Build();
await app.InitializeApplicationAsync();
await app.RunAsync();
建立BookAbpModule.cs
using Microsoft.OpenApi.Models;
using Volo.Abp;
using Volo.Abp.Application;
using Volo.Abp.AspNetCore.Mvc;
using Volo.Abp.Autofac;
using Volo.Abp.Domain;
using Volo.Abp.Modularity;
using Volo.Abp.Swashbuckle;
namespace BookApp
{
[DependsOn(
typeof(AbpAutofacModule),
typeof(AbpAspNetCoreMvcModule),
typeof(AbpSwashbuckleModule)
)]
public class BookAbpModule : AbpModule
{
override public void ConfigureServices(ServiceConfigurationContext context)
{
ConfigureSwaggerServices(context.Services);
}
override public void OnApplicationInitialization(ApplicationInitializationContext context)
{
var app = context.GetApplicationBuilder();
var env = context.GetEnvironment();
app.UseStaticFiles();
app.UseRouting();
app.UseSwagger();
app.UseAbpSwaggerUI(options =>
{
options.SwaggerEndpoint("/swagger/v1/swagger.json", "BookApp API");
});
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
}
private void ConfigureSwaggerServices(IServiceCollection services)
{
services.AddAbpSwaggerGen(
options =>
{
options.SwaggerDoc("v1", new OpenApiInfo { Title = "BookApp API", Version = "v1" });
options.DocInclusionPredicate((docName, description) => true);
options.CustomSchemaIds(type => type.FullName);
}
);
}
}
}
模組化程式設計
新建AbpModuleA類庫並引用Volo.Abp.Core
//加AbpModuleAModule.cs
using System.IO;
using System;
using Volo.Abp.Modularity;
using Volo.Abp;
namespace AbpModuleA
{
public class AbpModuleAModule: AbpModule
{
public override void PreConfigureServices(ServiceConfigurationContext context)
{
Console.WriteLine("AbpModuleA.PreConfigureServices ");
}
override public void PostConfigureServices(ServiceConfigurationContext context)
{
Console.WriteLine("AbpModuleA.PostConfigureServices");
}
public override void ConfigureServices(ServiceConfigurationContext context)
{
Console.WriteLine("AbpModuleA.ConfigureServices");
}
public override void OnApplicationInitialization(ApplicationInitializationContext context)
{
Console.WriteLine("AbpModuleA.OnApplicationInitialization");
}
public override void OnPreApplicationInitialization(ApplicationInitializationContext context)
{
Console.WriteLine("AbpModuleA.OnPreApplicationInitialization");
}
override public void OnPostApplicationInitialization(ApplicationInitializationContext context)
{
Console.WriteLine("AbpModuleA.OnPostApplicationInitialization");
}
}
}
新建AbpModuleB類庫並引用Volo.Abp.Core
//加AbpModuleBModule.cs
using System.IO;
using System;
using Volo.Abp.Modularity;
using Volo.Abp;
namespace AbpModuleB
{
public class AbpModuleBModule: AbpModule
{
public override void PreConfigureServices(ServiceConfigurationContext context)
{
Console.WriteLine("AbpModuleB.PreConfigureServices");
}
override public void PostConfigureServices(ServiceConfigurationContext context)
{
Console.WriteLine("AbpModuleB.PostConfigureServices");
}
public override void ConfigureServices(ServiceConfigurationContext context)
{
Console.WriteLine("AbpModuleB.ConfigureServices");
}
public override void OnApplicationInitialization(ApplicationInitializationContext context)
{
Console.WriteLine("AbpModuleB.OnApplicationInitialization");
}
public override void OnPreApplicationInitialization(ApplicationInitializationContext context)
{
Console.WriteLine("AbpModuleB.OnPreApplicationInitialization");
}
override public void OnPostApplicationInitialization(ApplicationInitializationContext context)
{
Console.WriteLine("AbpModuleB.OnPostApplicationInitialization");
}
}
}
修改Api專案的模組配置檔案
//BookAbpModule.cs
using Microsoft.OpenApi.Models;
using Volo.Abp;
using Volo.Abp.Application;
using Volo.Abp.AspNetCore.Mvc;
using Volo.Abp.Autofac;
using Volo.Abp.Domain;
using Volo.Abp.Modularity;
using Volo.Abp.Swashbuckle;
using AbpModuleA;
using AbpModuleB;
namespace BookApp
{
[DependsOn(
typeof(AbpAutofacModule),
typeof(AbpAspNetCoreMvcModule),
typeof(AbpSwashbuckleModule),
typeof(AbpModuleAModule),
typeof(AbpModuleBModule)
)]
public class BookAbpModule : AbpModule
{
public override void PreConfigureServices(ServiceConfigurationContext context)
{
Console.WriteLine("BookAbpModule.PreConfigureServices ");
}
override public void PostConfigureServices(ServiceConfigurationContext context)
{
Console.WriteLine("BookAbpModule.PostConfigureServices");
}
override public void ConfigureServices(ServiceConfigurationContext context)
{
Console.WriteLine("BookAbpModule.ConfigureServices");
ConfigureSwaggerServices(context.Services);
}
override public void OnApplicationInitialization(ApplicationInitializationContext context)
{
Console.WriteLine("BookAbpModule.OnApplicationInitialization");
var app = context.GetApplicationBuilder();
var env = context.GetEnvironment();
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseStaticFiles();
app.UseRouting();
app.UseSwagger();
app.UseAbpSwaggerUI(options =>
{
options.SwaggerEndpoint("/swagger/v1/swagger.json", "BookApp API");
});
app.UseConfiguredEndpoints();
}
public override void OnPreApplicationInitialization(ApplicationInitializationContext context)
{
Console.WriteLine("BookAbpModule.OnPreApplicationInitialization");
}
override public void OnPostApplicationInitialization(ApplicationInitializationContext context)
{
Console.WriteLine("BookAbpModule.OnPostApplicationInitialization");
}
private void ConfigureSwaggerServices(IServiceCollection services)
{
services.AddAbpSwaggerGen(
options =>
{
options.SwaggerDoc("v1", new OpenApiInfo { Title = "BookApp API", Version = "v1" });
options.DocInclusionPredicate((docName, description) => true);
options.CustomSchemaIds(type => type.FullName);
}
);
}
}
}
執行結果
我們會發現，系統載入所有繼承AbpModule的檔案，並按序執行裡面的方法實現對模組的配置
訪問資料庫
新建Entities資料夾並建立Book.cs
using Volo.Abp.Domain.Entities;
namespace BookApp.Entities
{
public class Book : Entity<Guid>
{
public string Name { get; set; }
}
}
新增Data目錄並新增BookAbpDbContext.cs
using BookApp.Entities;
using Microsoft.EntityFrameworkCore;
using System.Collections.Generic;
using System.Reflection.Emit;
using Volo.Abp.Data;
using Volo.Abp.EntityFrameworkCore;
namespace BookApp.Data
{
[ConnectionStringName("Default")]
public class BookAbpDbContext : AbpDbContext<BookAbpDbContext>
{
public BookAbpDbContext(DbContextOptions<BookAbpDbContext> options)
: base(options)
{ }
public DbSet<Book> Books { get; set; }
protected override void OnModelCreating(ModelBuilder builder)
{
base.OnModelCreating(builder);
builder.Entity<Book>(b =>
{
b.ToTable(nameof(Books));
});
}
}
}
修改BookAbpModule.cs
using Microsoft.OpenApi.Models;
using Volo.Abp;
using Volo.Abp.Application;
using Volo.Abp.AspNetCore.Mvc;
using Volo.Abp.Autofac;
using Volo.Abp.Domain;
using Volo.Abp.Modularity;
using Volo.Abp.Swashbuckle;
using AbpModuleA;
using AbpModuleB;
using Volo.Abp.EntityFrameworkCore;
using BookApp.Data;
using Volo.Abp.EntityFrameworkCore.Sqlite;
namespace BookApp
{
[DependsOn(
typeof(AbpAutofacModule),
typeof(AbpAspNetCoreMvcModule),
typeof(AbpSwashbuckleModule),
typeof(AbpDddApplicationModule),
typeof(AbpDddDomainModule),
typeof(AbpEntityFrameworkCoreSqliteModule),
typeof(AbpModuleAModule),
typeof(AbpModuleBModule)
)]
public class BookAbpModule : AbpModule
{
public override void PreConfigureServices(ServiceConfigurationContext context)
{
Console.WriteLine("BookAbpModule.PreConfigureServices ");
}
override public void PostConfigureServices(ServiceConfigurationContext context)
{
Console.WriteLine("BookAbpModule.PostConfigureServices");
}
override public void ConfigureServices(ServiceConfigurationContext context)
{
Console.WriteLine("BookAbpModule.ConfigureServices");
ConfigureSwaggerServices(context.Services);
// 使用sqlite作為資料庫
context.Services.AddAbpDbContext<BookAbpDbContext>(options =>
{
options.AddDefaultRepositories(includeAllEntities: true);
});
Configure<AbpDbContextOptions>(options =>
{
options.UseSqlite();
});
}
override public void OnApplicationInitialization(ApplicationInitializationContext context)
{
Console.WriteLine("BookAbpModule.OnApplicationInitialization");
var app = context.GetApplicationBuilder();
var env = context.GetEnvironment();
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseStaticFiles();
app.UseRouting();
app.UseSwagger();
app.UseAbpSwaggerUI(options =>
{
options.SwaggerEndpoint("/swagger/v1/swagger.json", "BookApp API");
});
app.UseConfiguredEndpoints();
}
public override void OnPreApplicationInitialization(ApplicationInitializationContext context)
{
Console.WriteLine("BookAbpModule.OnPreApplicationInitialization");
}
override public void OnPostApplicationInitialization(ApplicationInitializationContext context)
{
Console.WriteLine("BookAbpModule.OnPostApplicationInitialization");
}
private void ConfigureSwaggerServices(IServiceCollection services)
{
services.AddAbpSwaggerGen(
options =>
{
options.SwaggerDoc("v1", new OpenApiInfo { Title = "BookApp API", Version = "v1" });
options.DocInclusionPredicate((docName, description) => true);
options.CustomSchemaIds(type => type.FullName);
}
);
}
}
}
修改appsettings.json
{
"ConnectionStrings": {
"Default": "Data Source=BookApp.db"
},
"Logging": {
"LogLevel": {
"Default": "Information",
"Microsoft.AspNetCore": "Warning"
}
},
"AllowedHosts": "*"
}
安裝Nuget包"Microsoft.EntityFrameworkCore.Tools",並在在專案根目錄下開啟命令列工具，依次執行以下命令進行資料遷移和資料庫更新：
dotnet ef migrations add InitialCreate
dotnet ef database update
新建Application目錄
新建IBookAppService.cs
namespace BookApp.Application
{
using BookApp.Entities;
public interface IBookAppService
{
Task<string> CreateAsync(string name);
Task<List<Book>> GetListAsync();
}
}
新建BookAppService.cs
using BookApp.Entities;
using Volo.Abp.Application.Services;
using Volo.Abp.Domain.Repositories;
namespace BookApp.Application
{
public class BookAppService : ApplicationService, IBookAppService
{
public IRepository<Book, Guid> Repository => LazyServiceProvider.LazyGetRequiredService<IRepository<Book, Guid>>();
public async Task<string> CreateAsync(string name)
{
var book = await Repository.InsertAsync(new Book()
{
Name = name
});
return book.Name;
}
public async Task<List<Book>> GetListAsync()
{
var list = await Repository.GetListAsync();
return list;
}
}
}
在Controllers目錄新建BookController.cs
using BookApp.Application;
using Microsoft.AspNetCore.Mvc;
using Volo.Abp.AspNetCore.Mvc;
using BookApp.Entities;
namespace BookApp.Controllers
{
[ApiController]
[Route("[controller]")]
public class BookController : AbpController
{
private readonly IBookAppService _service;
public BookController(IBookAppService service)
{
_service = service;
}
[HttpGet]
public Task<string> CreateAsync(string name)
{
return _service.CreateAsync(name);
}
[HttpGet("list")]
public Task<List<Book>> GetListAsync()
{
return _service.GetListAsync();
}
}
}
整個檔案結構與包引用情況如下
執行結果如下
我們可以透過這兩個介面新增與顯示Book資訊。
