Sitecore: enable sitecore component dependency

Question

I am using Sitecore 8.1 MVC with Autofac as DI. I was wondering how it is recommended to embed the allowed objects in the created sitecore objects, i.e. Conveyors, commands, computed fields, etc. As an example, I use a membership provider, in which I need to call my business level. Is it possible to define a class constructor and sitecore will inject objects?

thank

With things like pipelined processors, instructions, etc. Basically, everything that Sitecore creates is pretty limited. The usual approach is to use the Locator pattern to define dependencies:

var membershipProvider = DependencyResolver.Current.Resolve<IMembershipProvider>()

. : https://cardinalcore.co.uk/2014/07/02/sitecore-pipelines-commands-using-ioc-containers/ factory . :

using System;
using System.Diagnostics.CodeAnalysis;

using Sitecore.Reflection;

public class ContainerFactory : IFactory
{
    private readonly IContainerManager containerManager;

    public ContainerFactory() : this(new LocatorContainerManager()) // service locate an appropriate container
    {
    }

    public ContainerFactory(IContainerManager containerManager)
    {
        this.containerManager = containerManager;
    }

    public object GetObject(string identifier)
    {
        Type type = Type.GetType(identifier);
        return this.containerManager.Resolve(type);
    }
}

factory , factory . config:

<sitecore>
  <events>
    <event name="item:saved">
      <handler factory="ContainerFactory" ref="MyApp.MyHandler, MyApp" method="MyMethod">
        <database>master</database>
      </handler>
    </event>
  </events>
  <pipelines>
    <MyPipeline>
      <processor type="1" factory="ContainerFactory" ref="MyApp.MyProcessor, MyApp" />
    </MyPipeline>
  </pipelines>
  <factories>
    <factory id="ContainerFactory" type="MyApp.ContainerFactory"></factory>
  </factories>
</sitecore>
