mvc5整合Autofac

本文中将使用 mvc5与webapi2进行对Autofac整合

准备工作：

　　1、vs2013 or vs2013+

　　2、网络良好,nuget正常访问

好了需要的准备工作就这么多。

-----------------------------分割线---------------------------------------

1、首先新建一个mvc5 与 webapi2 的项目如下图

2、安装相应的插件：

   <package id="Autofac" version="3.5.0" targetFramework="net46" />
   <package id="Autofac.Configuration" version="3.3.0" targetFramework="net46" />
   <package id="Autofac.Mvc5" version="3.3.4" targetFramework="net46" />
   <package id="Autofac.Mvc5.Owin" version="3.1.0" targetFramework="net46" />
   <package id="Autofac.Owin" version="3.1.0" targetFramework="net46" />
   <package id="Autofac.WebApi2" version="3.4.0" targetFramework="net46" />
   <package id="Autofac.WebApi2.Owin" version="3.3.0" targetFramework="net46" />

ps：请参考id进行进行安装

3、在Startup文件中配置 Autofac（ps:看下面代码 有很多可选配置 应为我没有用到就注释了。例如builder.RegisterModelBinders(Assembly.GetExecutingAssembly())  因为我没有自定义ModelBinders 就启用）

 public partial class Startup
     {
         public void Configuration(IAppBuilder app)
         {
             //ConfigureAuth(app);
             var builder = new ContainerBuilder();
             // Register dependencies, then...
             IOCRegister.Init(builder);

             // Register your MVC controllers.
             builder.RegisterControllers(typeof(MvcApplication).Assembly);
             // OPTIONAL: Register model binders that require DI.
             //builder.RegisterModelBinders(Assembly.GetExecutingAssembly());
             //builder.RegisterModelBinderProvider();

             // OPTIONAL: Register web abstractions like HttpContextBase.
             //builder.RegisterModule<AutofacWebTypesModule>();

             // OPTIONAL: Enable property injection in view pages.
             //builder.RegisterSource(new ViewRegistrationSource());

             // OPTIONAL: Enable property injection into action filters.
             builder.RegisterFilterProvider();
             builder.RegisterApiControllers(Assembly.GetExecutingAssembly());
             var config = GlobalConfiguration.Configuration;
             // Set the dependency resolver to be Autofac.
             var container = builder.Build();
             DependencyResolver.SetResolver(new AutofacDependencyResolver(container));
             config.DependencyResolver = new AutofacWebApiDependencyResolver(container);
             app.UseAutofacMiddleware(container);
             app.UseAutofacMvc();
             app.UseAutofacWebApi(config);
         }
     }

 1 public class IOCRegister
     {
         public static void Init(ContainerBuilder builder)
         {
             XmlConfigurator.Configure(new FileInfo(Path.Combine(HttpContext.Current.Server.MapPath("/"), "log4net.config")));
             var logger = LogManager.GetLogger("");
             builder.RegisterInstance(logger).As<ILog>().SingleInstance();

             var configPath = Path.Combine(HttpContext.Current.Server.MapPath("/"), @"App_Data/Config");

             builder.RegisterModule(new ConfigurationSettingsReader("components", Path.Combine(configPath, "components.xml")));
             //更多配置文件.....

         }
     }

ps：以上代码使用配置文件的方法配置 注入实例

4、配置文件components.xml

 <?xml version="1.0" encoding="utf-8" ?>
 <components defaultAssembly="BA.Framework.Util">
   <files>
     <file name="App_Data/Config/services.xml" section="services" />
   </files>
 </components>

5、配置文件 services.xml

 <?xml version="1.0" encoding="utf-8" ?>
 <service defaultAssembly="WebApplication1Service">
   <components>
     <component
            type="WebApplication1Service.TestService"
            service="WebApplication1Service.ITestService"
            instance-scope="per-lifetime-scope">
       <parameters>
         <parameter name="name" value="adfasdfasdfasdfasdf" />
         <parameter name="age" value="121"/>
       </parameters>
     </component>

   </components>
 </service>

ps: 注意 defaultAssembly 需要配置注入类的命名空间

最后：关于TestService.cs

  public interface ITestService
     {
         string Test();

         TestModel GetInfo();

     }

     public class TestService : ITestService
     {

         private readonly string name;
         private readonly int age;

         public TestService(string name, int age)
         {
             this.name = name;
             this.age = age;
         }
         public int Count { set; get; }

         public string Test()
         {
             return "afdafdasdf";
         }

         public TestModel GetInfo()
         {
             return new TestModel()
             {
                 Age = age,
                 Name = name
             };
         }
     }

     public class TestModel
     {
         public string Name { get; set; }
         public int Age { set; get; }
     }

Controller里使用Service：

 public class Home2Controller : ApiController
    {
        private readonly ITestService _testService;
        public Home2Controller(ITestService testService)
        {
            _testService = testService;
        }
        public TestModel Get()
        {
            return _testService.GetInfo();
        }
    }
