今天自己搭了一套基于三层的依赖注入mvc web api 的依赖注入框架,在此总结下相关配置
1.设置应用程序的.net Framework版本为 4.5
2.通过Nuget 安装autofac包
Install-Package Autofac
Install-Package Autofac.WebApi
3.引用如下命名空间
using Autofac;
using Autofac.Integration.WebApi;
using Autofac.Integration.Mvc;
using System.Web.Mvc;
4.再按照如下代码配置Autofac(分别搭建DAL、BLL、IDAL、IBLL)
public static void Register()
{
var builder = new ContainerBuilder();
HttpConfiguration configuration = GlobalConfiguration.Configuration;
var assemblyList = AppDomain.CurrentDomain.GetAssemblies();
builder.RegisterWebApiFilterProvider(configuration);
//var iServices = Assembly.Load("IOC.IBLL");
//var services = Assembly.Load("IOC.BLL");
//var iRepository = Assembly.Load("IOC.IDAL");
//var repository = Assembly.Load("IOC.DAL");
//builder.RegisterAssemblyTypes(iServices, services)
// .Where(t => t.Name.EndsWith("Service"))
// .AsImplementedInterfaces();
//var test = builder.RegisterAssemblyTypes(iRepository, repository)
// .Where(t => t.Name.EndsWith("Dal"))
// .AsImplementedInterfaces();
builder.RegisterAssemblyTypes(assemblyList)
.Where(t => t.Name.EndsWith("Service") || t.Name.EndsWith("Dal"))
.AsImplementedInterfaces();
builder.RegisterControllers(Assembly.GetExecutingAssembly()).PropertiesAutowired(); //注册所有controller
builder.RegisterApiControllers(Assembly.GetExecutingAssembly()).PropertiesAutowired(); //注册所有apicontroller
var container = builder.Build();
configuration.DependencyResolver = new AutofacWebApiDependencyResolver(container);//注册api容器
DependencyResolver.SetResolver(new AutofacDependencyResolver(container));//注册mvc容器
}
5.在Application_Start里调用 AutofacConfig.Register();
6.然后在每一层采用构造函数依赖注入方式。
