ASP.NET Core修改IOC为Autofac
如下是我为了了解如何更换ASP.NET Core中的IOC而查找的文章,如果大家英文OK的,可以直接前往阅读,同时也已经有简单的github例子供大家参考。
参考文章:
ASP.NET Core文档:https://docs.asp.net/en/latest/fundamentals/dependency-injection.html#replacing-the-default-services-container
Autofac文档:http://docs.autofac.org/en/latest/integration/aspnetcore.html
Autofac官网的Example:https://github.com/autofac/Examples/tree/master/src/AspNetCoreExample
有了上面的参考文章,其他多余的废话也不说了,直接说重点。
1. 在Nuget上,找到Autofac和Autofac.Extensions.DependencyInjection,直接安装。
2. 修改Startup.cs中的代码,主要ConfigureServices(IServiceCollection services)方法。其中该方法默认的返回值为void,这里需要修改返回值为IServiceProvider。代码如下:
public IContainer ApplicationContainer { get; private set; } // ConfigureServices is where you register dependencies. This gets // called by the runtime before the Configure method, below. public IServiceProvider ConfigureServices(IServiceCollection services) { // Add services to the collection. services.AddMvc(); // Create the container builder. var builder = new ContainerBuilder(); // Register dependencies, populate the services from // the collection, and build the container. If you want // to dispose of the container at the end of the app, // be sure to keep a reference to it as a property or field. builder.RegisterType<MyType>().As<IMyType>(); builder.Populate(services); this.ApplicationContainer = builder.Build(); // Create the IServiceProvider based on the container. return new AutofacServiceProvider(this.ApplicationContainer); }
