如何在 ASP.NET Core MVC 2.0 的另一个程序集中使用控制器?

How to use a controller in another assembly in ASP.NET Core MVC 2.0?(如何在 ASP.NET Core MVC 2.0 的另一个程序集中使用控制器?)

问题描述

为了模块化，我在不同的程序集中创建了一些控制器.每个程序集代表整个系统的一个有界上下文(一个模块、一个子系统、一个部门等).

For the sake of modularity, I have created some controllers in different assemblies. Each assembly represents a bounded context (a module, a sub-system, a division, etc.) of the overall system.

每个模块的控制器都是由对其他模块一无所知的人开发的，中央编排器即将在一个应用程序中涵盖所有这些模块.

Each module's controllers are developed by someone that knows nothing about other modules, and a central orchestrator is about to cover all these modules in one single application.

所以，有一个名为 school 的模块，其中有一个 TeacherController.它的输出是 Contoso.School.UserService.dll.

So, there is this module called school, and it has a TeacherController in it. The output of it is Contoso.School.UserService.dll.

主编排器名为 Education，它引用了 Contoso.School.UserService.dll.

The main orchestrator is called Education and it has a reference to Contoso.School.UserService.dll.

我的 program.cs 是:

    public static IWebHost BuildWebHost(string[] args) =>
        WebHost.CreateDefaultBuilder(args).UseKestrel()
            .UseStartup<Startup>()
            .Build();

但是对于教师控制器的路由，我得到 404.如何在其他程序集中使用控制器?

Yet for the routes of teacher controller, I get 404. How to use controllers in other assemblies?

推荐答案

在 Startup 类的 ConfigureServices 方法中，您必须调用以下代码:

Inside the ConfigureServices method of the Startup class you have to call the following:

services.AddMvc().AddApplicationPart(assembly).AddControllersAsServices();

其中 assembly 是代表 Contoso.School.UserService.dll 的实例 Assembly.

Where assembly is the instance Assembly representing Contoso.School.UserService.dll.

您可以从任何包含的类型中获取它或像这样加载它:

You can load it either getting it from any included type or like this:

var assembly = Assembly.Load("Contoso.School.UserService");
