简单了解：

 项目代码：

owin+webapi中使用Autofac:

添加Nuget包：

Autofac Autofac.WebApi2.Owin

 

owin中添加：

//注册依赖注入            ContainerBuilder builder = new ContainerBuilder();            // Register your Web API controllers.            builder.RegisterApiControllers(Assembly.GetExecutingAssembly());                        builder.RegisterType
     
      ().As
      
       ();            builder.RegisterType
       
        ().As
        
         ();            // Run other optional steps, like registering filters,            // per-controller-type services, etc., then set the dependency resolver            // to be Autofac.            IContainer container = builder.Build();            config.DependencyResolver = new AutofacWebApiDependencyResolver(container);            // OWIN WEB API SETUP:            // Register the Autofac middleware FIRST, then the Autofac Web API middleware,            // and finally the standard Web API middleware.            app.UseAutofacMiddleware(container);            app.UseAutofacWebApi(config);
        
       
      
     

 

①在Repository 仓储中写逻辑代码，Service  应用中调用仓储代码

列如：

 

 

 

 

 

②webapi中
