MVC Project Practice, implementing the Sportsstore-03,ninject controller factory in a three-tier architecture

Sportsstore is the MVC project demonstrated in the master ASP. NET MVC3 Framework (third edition), which covers many aspects of MVC, including: Using di containers, URL optimization, navigation, paging, shopping carts, orders, product management, image uploads ... is a good MVC practice project, but the project is not developed in a multi-layered framework, and there is a distance from the real project. This series will attempt to implement the Sportsstore project in a multi-layered framework and implement some functions in its own way.

This article is the third series, including:

5. Custom Ninject Controller Factory
6, the first operation of the project

5. Custom Ninject Controller Factory

Add the following references under Mysportsstore.webui:

Add a reference to Ninject
Add a reference to MYSPORTSSTORE.IBLL
Add a reference to MYSPORTSSTORE.BLL
Add a reference to Mysportsstore.model

Create Ninjectcontrollerfactory:

usingSYSTEM.WEB.MVC;usingMYSPORTSSTORE.BLL;usingMYSPORTSSTORE.IBLL;usingNinject;namespacemysportsstore.webui.extension{ Public classNinjectcontrollerfactory:defaultcontrollerfactory {PrivateIkernel Ninjectkernel;  Publicninjectcontrollerfactory () {Ninjectkernel=NewStandardkernel ();        Addbindings (); }        protected OverrideIController getcontrollerinstance (System.Web.Routing.RequestContext requestcontext, System.Type controllertype )        {            returnControllertype = =NULL?NULL: (IController) Ninjectkernel.get (Controllertype); }        Private voidaddbindings () {Ninjectkernel.bind<IProductService> (). To<productservice>(); }    }}

Registering ninjectcontrollerfactory in the global

 Public class MvcApplication:System.Web.HttpApplication    {        protectedvoid  Application_Start ()        {            ...            ControllerBuilder.Current.SetControllerFactory (new  ninjectcontrollerfactory ());        }    }

Why do I need ninjectcontrollerfactory?
Ninject This di container can help us manage interfaces and implementations well, and inject them into the controller as attributes or constructors to invoke the methods of the interface implementation class. Also, Ninject provides a get () method that allows you to create a controller using Ninject.

6, the first operation of the project

Create Basecontroller, which gives you a mechanism for manual garbage collection.

usingSystem;usingSystem.Collections.Generic;usingSYSTEM.WEB.MVC;namespacemysportsstore.webui.controllers{ Public classBasecontroller:controller {protectedIlist<idisposable> Disposableobjects {Get;Private Set; }  PublicBasecontroller () { This. Disposableobjects =NewList<idisposable>(); }        protected voidAdddisposableobject (Objectobj) {IDisposable disposable= obj asIDisposable; if(Disposable! =NULL)            {                 This.            Disposableobjects.add (disposable); }        }        protected Override voidDispose (BOOLdisposing) {            if(disposing) {foreach(IDisposable objinch  This. disposableobjects) {if(NULL!=obj) {obj.                    Dispose (); }                }            }            Base.        Dispose (disposing); }    }}

When the other controller is derived from Basecontroller, if a xxxservice of type ixxxservice is used, the adddisposableobject of the Basecontroller (object obj Put the Xxxservice in the Disposableobjects collection attribute in Basecontroller and destroy these Xxxservice using Dispose ().

In the Baseservice also provides the manual garbage collection mechanism, can recover the currentrepository in time.

Finally, a manual garbage collection mechanism is also provided in Baserepository, which can be used to reclaim EF context in a timely manner.

Create a Productcontroller to derive it from Basecontroller:

usingSYSTEM.WEB.MVC;usingMYSPORTSSTORE.IBLL;usingNinject;namespacemysportsstore.webui.controllers{ Public classProductcontroller:basecontroller {[Inject] iproductservice productservice {Get;Set; }  PublicProductcontroller () { This.        Adddisposableobject (Productservice); }         PublicViewResult List () {returnView (productservice.loadentities (p =true).        AsQueryable ()); }    }}

The corresponding prduct/list.cshtml views are:

@model ienumerable<mysportsstore.model.product>@{Viewbag.title="List"; Layout="~/views/shared/_layout.cshtml";} @foreach (varIteminchModel) {    <divclass="Item"> @item. Description"C") }

To enable EF to automatically create the database and display it at the first run, we also need to configure the connection string in Web. config in Mysportsstore.webui:

<connectionStrings> ...     <add name="conn"       connectionString="Data source=.; User=some user name; Password=some password;initial catalog=mysportsstore;integrated security=true"        ProviderName="System.Data.SqlClient"/>  </connectionstrings >

Modify the default route to:

routes. MapRoute (                "Default",                "{Controller}/{action}/{id}  ",                new"Product""List  ", id = urlparameter.optional}            );

Run and get the following interface:

The Mysportsstore database has also been added to the database:
