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();
        }
    }
