1 首先创建一个WebApi项目

2 初步整合ABP模块化

Abp官网，这里我们先初步整合WebApi模块化，待程序运行起来，后续文章我们再对Abp进行深入。

2.1 NuGet：包Volo.Abp

Volo,Abp：模块化必备

2.2 NuGet：Volo.Abp.AspNetCore

Volo.Abp.AspNetCore：装配Web项目DI容器注入必备

2.3 NuGet：Volo.Autofac

Volo.Autofac：Abp的DI容器

2.4.创建一个模块化Module类

    [DependsOn(typeof(AbpAspNetCoreModule))]
    public class AdminGatewayModule : AbpModule
    {
        public override void ConfigureServices(ServiceConfigurationContext context)
        {
            // Add services to the container.

            context.Services.AddControllers();
            // Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle

            context.Services.AddEndpointsApiExplorer();
            context.Services.AddSwaggerGen();
        }
        public override void OnApplicationInitialization(ApplicationInitializationContext context)
        {
            var env = context.GetEnvironment();

            var app = context.GetApplicationBuilder();

            if (env.IsDevelopment())
            {
                app.UseSwagger();
                app.UseSwaggerUI();
            }

            app.UseRouting();

            app.UseEndpoints(endpoint =>
            {
                endpoint.MapControllers();
            });
        }
    }

2.5 修改Program启动配置

    public class Program
    {
        public async static Task Main(string[] args)
        {
            var builder = WebApplication.CreateBuilder(args);

            builder.Host.ConfigureAppConfiguration((context, builder) =>
            {
                builder.AddJsonFile($"appsettings.{context.HostingEnvironment.EnvironmentName}.json",
                    optional: true, reloadOnChange: true)
                .AddEnvironmentVariables();
            }).UseAutofac();

            await builder.AddApplicationAsync<IdentityServerHostModule>();

            var app = builder.Build();

            await app.InitializeApplicationAsync();

            await app.RunAsync();
        }
    }
