废话不多说，直接上代码

    public static class MvcContainer{public static IContainer Instance;public static System.Web.Mvc.IDependencyResolver Init(Func<ContainerBuilder, ContainerBuilder> func = null){var builder = new ContainerBuilder();//新建容器用于注册组件MyBuild(builder);//注册组件func?.Invoke(builder);Instance = builder.Build();//利用构建器创建容器return new AutofacDependencyResolver(Instance);//返回针对MVC的解析器}public static void MyBuild(ContainerBuilder builder){//注册仓储层Assembly repositoryAssembly = Assembly.Load("WenYuanAutoAutoFac.Repository");builder.RegisterAssemblyTypes(repositoryAssembly).PublicOnly()   //只要public访问权限的.Where(cc => cc.IsClass)    //只要class类型的(排除值和interface类型).AsImplementedInterfaces(); //自动以其实现的接口暴露(包括Dispose接口)//注册逻辑层Assembly serviceAssembly = Assembly.Load("Wangxc.AutoFac.Service");builder.RegisterAssemblyTypes(serviceAssembly).PublicOnly().Where(cc => cc.IsClass).AsImplementedInterfaces();//注册MVC项目中拆分出来的不同Areas下面的ControllerAssembly MvcAssembly = Assembly.Load("Portal");Assembly XsAssembly = Assembly.Load("XS");Assembly ReportAssembly = Assembly.Load("Report");Assembly KcAssembly = Assembly.Load("KC");Assembly[] Assemblys = new Assembly[] { MvcAssembly , XsAssembly,ReportAssembly,KcAssembly};builder.RegisterControllers(Assemblys);}}
