Autofac的注入和web.config配合

public static void BuildMvcContainer()        {            var builder = new ContainerBuilder();            var assemblys = AppDomain.CurrentDomain.GetAssemblies().ToList();            //拆分DLL后需要注冊(cè)，需要注入的DLL            Assembly[] asm = GetAllAssembly("*.Controllers.dll").ToArray();            builder.RegisterAssemblyTypes(asm);　　　　　　　//讀取web.config中配置的值　            builder.RegisterModule(new ConfigurationSettingsReader("autofac"));                        var container = builder.Build();            DependencyResolver.SetResolver(new AutofacDependencyResolver(container));        }

        #region 加載程序集        PRivate static List<Assembly> GetAllAssembly(string dllName)        {            List<string> pluginpath = FindPlugin(dllName);            var list = new List<Assembly>();            foreach (string filename in pluginpath)            {                try                {                    string asmname = Path.GetFileNameWithoutExtension(filename);                    if (asmname != string.Empty)                    {                        Assembly asm = Assembly.LoadFrom(filename);                        list.Add(asm);                    }                }                catch (Exception ex)                {                    Console.Write(ex.Message);                }            }            return list;        }        //查找所有插件的路徑        private static List<string> FindPlugin(string dllName)        {            List<string> pluginpath = new List<string>();                           string path = AppDomain.CurrentDomain.BaseDirectory;                string dir = Path.Combine(path, "bin");                string[] dllList = Directory.GetFiles(dir, dllName);                if (dllList.Length > 0)                {                    pluginpath.AddRange(dllList.Select(item => Path.Combine(dir, item.Substring(dir.Length + 1))));                }            return pluginpath;        }        #endregion

上面的代碼就是注冊(cè)的代碼，我是在MVC4使用，寫(xiě)完之后再Global.asax中的application_Start調(diào)用，確保啟動(dòng)應(yīng)用后執(zhí)行

然后是web.config中配置

  <autofac configSource="Configuration/autofac.config" />

我web.config中引用一個(gè)文件，詳細(xì)看我之前的博文

<?xml version="1.0" encoding="utf-8"?><autofac>  <components>    <component  type="Cactus.Service.TestServer, Cactus.Service" service="Cactus.IService.TestInterface,Cactus.IService" />    <component  type="Cactus.Service.SiteConfigService, Cactus.Service" service="Cactus.IService.ISiteConfigService,Cactus.IService" />    <component  type="Cactus.Service.ActionGroupServer, Cactus.Service" service="Cactus.IService.IActionGroupServer,Cactus.IService" />    <component  type="Cactus.Service.ActionServer, Cactus.Service" service="Cactus.IService.IActionServer,Cactus.IService" />    <component  type="Cactus.Service.RoleServer, Cactus.Service" service="Cactus.IService.IRoleServer,Cactus.IService" />    <component  type="Cactus.Service.UserServer, Cactus.Service" service="Cactus.IService.IUserServer,Cactus.IService" />  </components></autofac>

然后在autofac.config中注冊(cè)服務(wù)，type是實(shí)現(xiàn)的server，service是接口

在MVC中的使用，根據(jù)的是構(gòu)造函數(shù)注入

public class AdminLoginController : Controller    {        public readonly IUserServer userServer;        public AdminLoginController(IUserServer userServer)        {            this.userServer = userServer;        }        public ActionResult Index()        {            userServer.xxxxx//隨便寫(xiě)            return View();        }}
