Spring.NET 1.3.1 新特性探索系列1——ASP.NET MVC的依赖注入
本文内容纲要：Spring.NET 1.3.1 新特性探索系列1——ASP.NET MVC的依赖注入
Spring.NET 1.3.1的程序集Spring.Web.Mvc提供对ASP.NET MVC程序的整合。其中SpringControllerFactory类继承自DefaultControllerFactory，以便于实现Spring.NET对Controller的管理
SpringControllerFactory
publicclass SpringControllerFactory : DefaultControllerFactory
{
privatestatic IApplicationContext _context;
///
/// Gets the application context.
///
///
publicstatic IApplicationContext ApplicationContext
{
get
{
if (_context ==null|| _context.Name != ApplicationContextName)
{
if (string.IsNullOrEmpty(ApplicationContextName))
{
_context = ContextRegistry.GetContext();
}
else
{
_context = ContextRegistry.GetContext(ApplicationContextName);
}
}
return _context;
}
}
///
/// Gets or sets the name of the application context.
///
///
/// Defaults to using the root (default) Application Context.
///
///
publicstaticstring ApplicationContextName { get; set; }
///
/// Creates the specified controller by using the specified request context.
///
///The context of the HTTP request, which includes the HTTP context and route data.
///The name of the controller.
///
///
///
publicoverride IController CreateController(RequestContext requestContext, string controllerName)
{
IController controller;
if (ApplicationContext.ContainsObjectDefinition(controllerName))
{
controller = ApplicationContext.GetObject(controllerName) as IController;
}
else
{
controller =base.CreateController(requestContext, controllerName);
}
AddActionInvokerTo(controller);
return controller;
}
///
/// Retrieves the controller instance for the specified request context and controller type.
///
///The context of the HTTP request, which includes the HTTP context and route data.
///The type of the controller.
///
///
///
///
///
///
protectedoverride IController GetControllerInstance(RequestContext requestContext, Type controllerType)
{
IController controller =null;
if (controllerType !=null)
{
var controllers = ApplicationContext.GetObjectsOfType(controllerType);
if (controllers.Count >0)
{
controller = (IController)controllers.Cast
}
}
else
{
//pass to base class for remainder of handling if can't find it in the context
controller =base.GetControllerInstance(requestContext, controllerType);
}
AddActionInvokerTo(controller);
return controller;
}
///
/// Adds the action invoker to the controller instance.
///
///The controller.
protectedvirtualvoid AddActionInvokerTo(IController controller)
{
if (controller ==null)
return;
if (typeof(Controller).IsAssignableFrom(controller.GetType()))
{
((Controller)controller).ActionInvoker =new SpringActionInvoker(ApplicationContext);
}
}
}
让我们开始实现对ASP.NET依赖注入的实现。
一、首先引用程序集Spring.Web.Mvc.dll，此程序可以脱离Spring.NET独立使用。
二、修改MvcApplication类，继承SpringMvcApplication。
让我们看下SpringMvcApplication类的代码
SpringMvcApplication
publicabstractclass SpringMvcApplication : HttpApplication
{
///
/// Handles the Start event of the Application control.
///
///The source of the event.
///The
protectedvirtualvoid Application_Start(object sender, EventArgs e)
{
RegisterAreas();
RegisterRoutes(RouteTable.Routes);
}
///
/// Configures the
///
///
/// You must override this method in a derived class to control the manner in which the
///
///
protectedvirtualvoid ConfigureApplicationContext()
{
}
///
/// Executes custom initialization code after all event handler modules have been added.
///
publicoverridevoid Init()
{
base.Init();
//the Spring HTTP Module won't have built the context for us until now so we have to delay until the init
ConfigureApplicationContext();
RegisterSpringControllerFactory();
}
///
/// Registers the areas.
///
///
/// Override this method in a derived class to modify the registered areas as neeeded.
///
protectedvirtualvoid RegisterAreas()
{
AreaRegistration.RegisterAllAreas();
}
///
/// Registers the routes.
///
///
/// Override this method in a derived class to modify the registered routes as neeeded.
///
protectedvirtualvoid RegisterRoutes(RouteCollection routes)
{
// This IgnoreRoute call is provided to avoid the trouble of CASSINI passing all req's thru
// ASP.NET (and thus the controller pipeline) during debugging
// see http://stackoverflow.com/questions/487230/serving-favicon-ico-in-asp-net-mvc and elsewhere for more info
routes.IgnoreRoute("{*favicon}", new { favicon =@"(.*/)?favicon.ico(/.*)?" });
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller ="Home", action ="Index", id = UrlParameter.Optional } // Parameter defaults
);
}
///
/// Registers the controller factory with the Mvc Framework.
///
protectedvirtualvoid RegisterSpringControllerFactory()
{
ControllerBuilder.Current.SetControllerFactory(typeof(SpringControllerFactory));
}
}
这样，我们在增加Route规则的时候，可以重写RegisterRoutes方法。
MvcApplication
publicclass MvcApplication : SpringMvcApplication
{
protectedoverridevoid RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // 路由名称
"{controller}/{action}/{id}", // 带有参数的 URL
new { controller ="Home", action ="Index", id = UrlParameter.Optional } // 参数默认值
);
}
}
三、给HomeController增加一个属性。
HomeController
publicclass HomeController : Controller
{
publicstring Message { get; set; }
public ActionResult Index()
{
ViewData["Message"] =this.Message;
return View();
}
public ActionResult About()
{
return View();
}
}
四、增加Controller配置Controllers.xml。
Controllers.xml
五、配置Web.config
Web.config
运行效果
