Modularity 模块化

单体模块化

• https://github.com/thinktecture-labs/aspnetcore-modular-monolith

因为类名如 Autofac 和 aspnetcore 中的类相同，将类名修改成如下名称

• Module.cs-->ModuleInfo.cs
• IStartup.cs-->IModuleStartup.cs

创建一个类库名 Module1，并引用 AspNetCore 包

   <ItemGroup>
		<FrameworkReference Include="Microsoft.AspNetCore.App" />
   </ItemGroup>

集成接口，可在ConfigureServices中注入任何服务，在Configure方法中注入中间件

public class Module1Startup : IModuleStartup
{
    public void ConfigureServices(IServiceCollection services)
    {
        //services.AddSingleton<ITestService, TestService>();
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        app.UseEndpoints(endpoints =>
            endpoints.MapGet("/TestEndpoint",
                async context =>
                {
                    await context.Response.WriteAsync("Hello World from TestEndpoint in Module 1");
                }).RequireAuthorization()
        );
    }
}

使用控制器

using Microsoft.AspNetCore.Mvc;

[Route("[module]/[controller]")]
public class TestController : Controller
{
    [HttpGet]
    public ActionResult<string> Index()
    {
        return "Hello World from TestController in Module 1";
    }

    /// <summary>
    /// InterModule
    /// </summary>
    /// <returns></returns>
    [HttpGet("InterModule")]
    public ActionResult<string> InterModule()
    {
        return $"{0} in TestController in Module 1";
    }
}

• 主程序Program

// Register a convention allowing to us to prefix routes to modules.
builder.Services.AddTransient<IPostConfigureOptions<MvcOptions>, ModuleRoutingMvcOptionsPostConfigure>();

// Adds module1 with the route prefix module-1
builder.Services.AddModule<Module1.Module1Startup>("module-1");

// Adds module2 with the route prefix module-2
builder.Services.AddModule<Module2.Module2Startup>("module-2");

• 注入中间件

// Adds endpoints defined in modules
var modules = app.Services.GetRequiredService<IEnumerable<ModuleInfo>>();
foreach (var module in modules)
{
    app.Map($"/{module.RoutePrefix}", builder =>
    {
        builder.UseRouting();
        module.Startup.Configure(builder, app.Environment);
    });
}
