1. Install
Install-Package Autofac
Install-Package Autofac.Extensions.DependencyInjection
2.Startup
2.1 增加成員
public IContainer ApplicationContainer { get; private set; }
2.2 Startup.ConfigureServices
返回值改為:IServiceProvider
末尾中增加:
//******************* autofac start ***********************
// Create the container builder.
var autofacBuilder = new ContainerBuilder();
autofacBuilder.RegisterType<TCPCollectorApplicationService>().As<ITCPCollectorApplicationService>();
autofacBuilder.Populate(services);
this.ApplicationContainer = autofacBuilder.Build();
return new AutofacServiceProvider(this.ApplicationContainer);
//******************* autofac start ***********************
3. Usage
3.1 构造注入
直接構造注入即可使用。
public TodoController(IKnowledgeApplicationService knowledgeApplicationService, ITCPCollectorApplicationService tcpCollectorApplicationService, IServiceProvider serviceProvider)
{
KnowledgeApplicationService = knowledgeApplicationService;
TCPCollectorApplicationService = tcpCollectorApplicationService;
ServiceProvider = serviceProvider;
}
3.2 使用ServiceProvider获取。
var tcpSvc = ServiceProvider.GetService(typeof(ITCPCollectorApplicationService)) as ITCPCollectorApplicationService;
return Ok(tcpSvc.GetAll());
