net5 Autofac支持

1、Nuget引入程序包

2、指定Autofac工厂替换默认工厂,Program指定

public static IHostBuilder CreateHostBuilder(string[] args) =>
           Host.CreateDefaultBuilder(args)
               .ConfigureWebHostDefaults(webBuilder =>
               {
                   webBuilder.UseStartup<Startup>();
               })
               .UseServiceProviderFactory(new AutofacServiceProviderFactory());

3、在Startup类增加ConfigureContainer 方法　

public void ConfigureContainer(ContainerBuilder builder)
       {
           builder.RegisterType<CustomServiceA>().As<ICustomServiceA>();
       }

4、通过控制器构造函数注入，获取实例

 

public class FirstController : Controller
{
    private readonly IConfiguration _Configuratin;

    public FirstController(IConfiguration configuration)//构造函数注入
    {
        _Configuratin = configuration;
    }

    public IActionResult Index()
    {
        ViewBag.Conn= _Configuratin["connstr"]; 
        return View();
    }
}
