One of the. NET MVC4 Training Records (introduction of Unity3.0 IOC framework)

has been doing maintenance projects, without the opportunity to contact the complete architecture, so self-taught. NET MVC. Since today, the process of self-study, problems encountered and solutions have been recorded.

Right-click in the WebApp project and use NuGet to introduce Unity3.0.

　　

A Bootstrapper.cs file is automatically generated when the project directory is introduced.

　　

Manually create the Ioc.config file under the WebApp root directory to configure IOC rules. (Note: The configuration file in the online tutorial before the,<typealiases></typealiases> node and the <unity></unity> node peer, but the runtime is always abnormal, The definition of ibaseservice could not be found. The assembly that contains the custom type should not be found. After I move the <typeAliases></typeAliases> node to the inside of <unity></unity>, the exception is gone. ）

Modify the Buildunitycontainer () method in the Bootstrapper.cs file:

1PrivateStaticIunitycontainer Buildunitycontainer ()2{3var container =NewUnityContainer ();45//Register all your components and the container here6//It isn't necessary to register your controllers78//Get the IOC configuration file location9String configfile = System.Web.HttpRuntime.AppDomainAppPath +"Ioc.config";10//Setting the extension profile type11var filemap =New Execonfigurationfilemap {execonfigfilename =ConfigFile};12//Reading configuration information from the config fileSystem.Configuration.Configuration config =14 Configurationmanager.openmappedexeconfiguration (Filemap, Configurationuserlevel.none); 15 // Gets the configuration section for the specified name 16 unityconfigurationsection configuration = (unityconfigurationsection) config. GetSection ( "unity" Span style= "color: #000000;" >); 17 // Configure IOC container 18  configuration. Configure (container); 19 20 return container; 21}             

Initialize the IOC container in Globale.asax.cs:

1ProtectedvoidApplication_Start ()2{3 Arearegistration.registerallareas ();  5  Filterconfig.registerglobalfilters ( Globalfilters.filters);  Routeconfig.registerroutes (routetable.routes); Span style= "color: #008080;" > 8  Bundleconfig.registerbundles (bundletable.bundles);  Authconfig.registerauth (); 11 bootstrapper.initialise (); // Initialize IOC container 12}  

Add the Ibaseservice type attribute to the controller, plus the [Dependency] tag so that it can be used directly in the controller.

　　

The IOC Framework Unity 3.0 was introduced to completion.
