web Api 用 windsor 注入

第一步 创建API controller 注入类

public class ApiControllersInstaller : IWindsorInstaller
{
  public void Install(IWindsorContainer container, IConfigurationStore store)
  {
     container.Register(Classes.FromThisAssembly().BasedOn<System.Web.Http.ApiController>().LifestyleTransient());
  }
}

第二步 创建windsor contain 安装类

public static class WindsorBootstrapper
{
   private static IWindsorContainer _container;

   public static void Initialize()
   {
      _container = new WindsorContainer();
      _container.Install(FromAssembly.This());
      _container.Register(Component.For<IWindsorContainer>().Instance(_container).LifestyleSingleton());

    }

   public static IWindsorContainer Container
   {
    get
    {
       return _container;
     }
   }
  }
}

 

第三步 创建WindsorCompositionRoot 类

public class WindsorCompositionRoot:IHttpControllerActivator
{
    private readonly IWindsorContainer _container;
    public WindsorCompositionRoot(IWindsorContainer container)
    {
        _container = container;
     }
     public IHttpController Create( HttpRequestMessage request,HttpControllerDescriptor controllerDescriptor,Type controllerType)
    {
       var controller =
       (IHttpController)_container.Resolve(controllerType);

       request.RegisterForDispose(
       new Release(
       () => _container.Release(controller)));

      return controller;
    }
    private class Release : IDisposable
    {
       private readonly Action _release;

       public Release(Action release)
       {
         _release = release;
       }

       public void Dispose()
      {
         _release();
      }
   }
}

第四步  Global.asax 注入

public class WebApiApplication : HttpApplication
{
    protected void Application_Start()
    {
        WindsorBootstrapper.Initialize();

       GlobalConfiguration.Configuration.Services.Replace(typeof(IHttpControllerActivator),new WindsorCompositionRoot(WindsorBootstrapper.Container));

    }
}
