Migrate from ASP.NET Core 2.2 to 3.0 -> Use MVC without Endpoint Routing

ASP.NET Core 2.0 : 七.一張圖看透啟動背後的秘密

本人測試環境

vs2019

.net core3.0

庫版本

Volo.Abp.AspNetCore.Mvc  1.02

Volo.Abp.Autofac 1.02

步驟:

參考上文, 可建立一個helloworld工程.

說明:

  vs2019建立工程可能有些許差別, 但原理基本一致.

遇到問題:

  1.原文使用的庫在本人測試時已經有所升級(abp團隊已從.net core2.2升級為3.0), AppModule類中app.UseMvcWithDefaultRoute();報異常:

　　Using 'UseMvc' to configure MVC is not supported while using Endpoint Routing. To continue using 'UseMvc', please set 'MvcOptions.EnableEndpointRounting = false' inside 'ConfigureServices'.

  解決方法:

　　a.註釋該行代碼;

　　b.修改startup.cs

public class Startup
    {
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddApplication<AppModule>();
            //添加
            services.AddMvc(option => option.EnableEndpointRouting = false);
        }

        public void Configure(IApplicationBuilder app)
        {
            app.InitializeApplication();
            //添加
            app.UseRouting();
            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllerRoute(
                    name: "default",
                    pattern: "{controller}/{action=Index}/{id?}");
            });
        }
    }

 運行,解決.

其他:

  隨著升級, autofac的使用也變的簡單, 引入庫之後, 直接在Program.cs的CreateHostBuilder方法中直接添加.UserAutofac()即可

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>();
                })
　　　　　　　　　　//添加
                .UseAutofac();
    }
