Symfony2 Use Doctrine in Service Container

Question

How do I use Doctrine in a service container?

The Code just causes an error message \"Fatal error: Call to undefined method ...::get()\".

For Symfony 3.x

The most easy-peasy solution for me was to just turn on autowiring/autoconfiguring, and then injecting the service I needed via the constructor. Note that I have also allowed any controller to be injected as a service by setting resource: '../../src/AppBundle/*'

 #services.yml or config.yml
 services:
    _defaults:
        autowire: true
        autoconfigure: true
        public: false
    # Allow any controller to be used as a service
    AppBundle\:
        resource: '../../src/AppBundle/*'    
        # you can exclude directories or files
        # but if a service is unused, it's removed anyway
        exclude: '../../src/AppBundle/{Entity,Repository,Tests,DataFixtures,Form}'

Then in any service, you can inject & use the entity manager $em (or any other service/controller) via the constructor like this:

// class xyz
private $em;
// constructor
public function __construct(\Doctrine\ORM\EntityManager $em)  {
    $this->em = $em;
}
public function bar() {
    //Do the Database stuff
    $query = $this->em->createQueryBuilder();
    //Your Query goes here
    $result = $query->getResult();
}
