ASP. NET Web API, asp. netwebapi

Sample Code

When the project is started, create a dependency injection container

Define a static container IWindsorContainer

1 private static IWindsorContainer _ container;

In Application_Start (), create the container

1 _ container = new WindsorContainer ();

 

Call the Container Install method to register components in the Container.

1 _ container. Install (FromAssembly. This ());

This statement calls all Install methods in the IWindsorInstaller Interface Class in the entire Assembly to register components with the container. Run the following code:

1 public void Install(IWindsorContainer container, IConfigurationStore store)2 {3     container.Register(4         Component.For<IDPlatypusRepository>().ImplementedBy<DPlatypusRepository>().LifestylePerWebRequest());5 }

Specifically list the code for registering a Controler in the Container:

1 public void Install(IWindsorContainer container, IConfigurationStore store)2 {3       container.Register(Classes.FromThisAssembly()4              .BasedOn<ApiController>().LifestylePerWebRequest());5 }

 

Defines the WindsorDependencyResolver class that implements the IDependencyResolver interface, as the Resolver of global HttpConfiguration

var dependencyResolver = new WindsorDependencyResolver(_container);configuration.DependencyResolver = dependencyResolver;

 

Create an IHttpControllerActivator and change the Controller creation method to get

Implement the Create method of the IHttpControllerActivator Interface

1 public IHttpController Create(HttpRequestMessage request, HttpControllerDescriptor controllerDescriptor, Type controllerType)2 {3     var controller = (IHttpController)_container.Resolve(controllerType);4 5     request.RegisterForDispose(6         new Release(() => _container.Release(controller)));7 8     return controller;9 }

And register the Controller when the web request is Dispose.

Replace Default IHttpControllerActivator Behavior

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