Sitecore dependency injection

 

1. If there's a service provider in the constructor

serviceProvider.GetService<IRenderingConfig>() 

2. If no - use this 

DependencyResolver.Current.GetService<IErrorsController>())

ServiceLocator.ServiceProvider.GetService<ICountryRepository>();

3. Uses Sitecore.DependencyInjection

4. Without passing in the constructor new the concrete type and populate properties

To register the type:

using Globus.Feature.Products.Controllers;

using Microsoft.Extensions.DependencyInjection;

using Sitecore.DependencyInjection;

using Sitecore.LayoutService.Configuration;

namespace Globus.Feature.Products.Services

{

    public class ServiceConfigurator : IServicesConfigurator

    {

        public void Configure(IServiceCollection serviceCollection)

        {

            serviceCollection.AddScoped(typeof(IRenderingConfiguration), typeof(DefaultRenderingConfiguration));

        }

    }

}

Then add it in the config:

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">

    <sitecore>

        <pipelines>

            <httpRequestBegin>

                <processor type="Globus.Feature.Products.Pipelines.HttpRequestBegin.ItineraryItemResolver, Globus.Feature.Products" 

                           patch:before="processor[@type='Sitecore.Pipelines.HttpRequest.ItemResolver, Sitecore.Kernel']"  

                           resolve="true" />

            </httpRequestBegin>

          

            <initialize>

                <processor type="Globus.Feature.Products.Pipelines.Initialize.RegisterCustomRoute, Globus.Feature.Products" patch:before="processor[@type='Sitecore.Mvc.Pipelines.Loader.InitializeRoutes, Sitecore.Mvc']" />

            </initialize>

        </pipelines>

        <services>

            <configurator type="Globus.Feature.Products.Services.ServiceConfigurator, Globus.Feature.Products"/>

        </services>

    </sitecore>    

</configuration>

Then in the controller class:

protected readonly IRenderingConfiguration _JSSConfig;

Then add to constructor:

public ProductsController(

            IItinerariesRepository itinerariesRepository,

            IDeparturesRepository departuresRepository,

            IPromotionsRepository promotionsRepository,

            IRenderingConfiguration jssconfig

            )

======================

 public ProductsController(

            IItinerariesRepository itinerariesRepository,

            IDeparturesRepository departuresRepository,

            IPromotionsRepository promotionsRepository

            )

        {

            _itinerariesRepository = itinerariesRepository;

            _departuresRepository = departuresRepository;

            _promotionsRepository = promotionsRepository;

            // 1. When passed in the constructor            

            //_JSSConfig = jssconfig;

            // 2. When 'newed'

            //_JSSConfig = new DefaultRenderingConfiguration();

            //_JSSConfig.Name = "jss"; and so on

            // 3. 

            _JSSConfig = DependencyResolver.Current.GetService<IRenderingConfiguration>();

            //4. 

            _JSSConfig = ServiceLocator.ServiceProvider.GetService<IRenderingConfiguration>();

        }
