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

本人测试环境

vs2019

.net core3.0

库版本

Volo.Abp.AspNetCore.Mvc 1.02

Volo.Abp.Autofac 1.02

步骤:

参考上文, 可建立一个helloworld工程.

说明:

vs2019建立工程可能有些许差别, 但原理基本一致.

遇到问题:

1.原文使用的库在本人测试时已经有所升级(abp团队已从.net core2.2升级为3.0), AppModule类中app.UseMvcWithDefaultRoute();报异常:

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

解决方法:

　　a.注释该行代码;

　　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?}");
            });
        }
    }

运行,解决.

其他:

随着升级, autofac的使用也变的简单, 引入库之后, 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();
    }
