Error Symfony when command execute - symfony

Question

I create a symfony command that executes a function in a controller but when I run the command I get this error message:
[Symfony \ Component \ Debug \ Exception \ FatalThrowableError]
Fatal error: Call to a member function has () on null
My Services.yml
services:
app.site_batch:
class: App\SiteBundle\Controller\BatchController
arguments:
entityManager: "#doctrine.orm.entity_manager"
container: "#service_container"
My Controller
<?php
namespace App\SiteBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\ParamConverter;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use ChrisCom\BDDBundle\Entity\Paiement;
use ChrisCom\BDDBundle\Entity\BBooking;
/**
* #Route("/batch")
*/
class BatchController extends Controller
{
private $log_file;
private $output;
private function openLog($filename) { $this->log_file = fopen($this->get('kernel')->getLogDir() . '/' . $filename, 'a'); }
private function log($line, $message)
{
if ($this->log_file)
{
$msg = sprintf("[%s %s:%03d] %s\n", date('d/m/Y H:i:s'), basename(__FILE__), $line, $message);
fputs($this->log_file, $msg);
$this->output .= $msg;
}
}
private function closeLog() { if ($this->log_file) fclose($this->log_file); }
/**
* #Route("/check_bookings", name="batch_check_bookings")
*/
public function checkBookingsAction($simul)
{
$em = $this->getDoctrine()->getManager();
$rep_book = $em->getRepository('ChrisComBDDBundle:BBooking');
$cur_date = new \DateTime();
$format_cmp = 'YmdHis';
$flush = false;
....
My Command
<?php
namespace App\SiteBundle\Command;
use Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand;
use Symfony\Component\Console\Input\InputArgument;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Input\InputOption;
use Symfony\Component\Console\Output\OutputInterface;
class CheckBookingsCommand extends ContainerAwareCommand
{
protected function configure()
{
$this
->setName('cron:checkBookings')
->setDescription('Vérification des réservation')
->addOption(
'simul',
null,
InputOption::VALUE_NONE,
'Si défini, le programme ne fera pas de COMMIT en base de donnée'
);
}
protected function execute(InputInterface $input, OutputInterface $output)
{
$output->writeln("Starting the cron");
// Call the method here
$version = $this->getContainer()->get('app.bdd')->parameterGet('VERSION');
$simul = ($input->getOption('simul'));
if ($simul) $output->writeln("Mode simulation");
$output->writeln($this->getContainer()->get('app.site_batch')->checkBookingsAction($simul));
$output->writeln("Cron completed");
}
}
I searched but without result ...
Thank you for help.

In your BatchController :
public function checkBookingsAction($simul)
{
$em = $this->container->get('doctrine')->getManager();
// ...
}
When you use a controller as a service, you lose the possibility to use $this->getDoctrine().
