Using phpExcel out of controller - symfony

Question

I would use the PHPExcel bundle other than in a controller (to create a service), but I can not get it to work under these conditions.
Here is what I have written in the function 'execute' of the command file:
class XportXcelPourAnalyseCommand extends ContainerAwareCommand
....
protected function execute(InputInterface $input, OutputInterface $output){
....
$phpExcelObject = $this->getContainer('phpexcel')->createPHPExcelObject();
$phpExcelObject->getProperties()->setCreator("liuggio")
->setLastModifiedBy("Giulio De Donato")
->setTitle("Office 2005 XLSX Test Document")
->setSubject("Office 2005 XLSX Test Document")
->setDescription("Test document for Office 2005 XLSX, generated using PHP classes.")
->setKeywords("office 2005 openxml php")
->setCategory("Test result file");
$phpExcelObject->setActiveSheetIndex(0)
->setCellValue('A1', 'Hello')
->setCellValue('B2', 'world!');
$phpExcelObject->getActiveSheet()->setTitle('Simple');
// Set active sheet index to the first sheet, so Excel opens this as the first sheet
$phpExcelObject->setActiveSheetIndex(0);
// create the writer
$writer = $this->get('phpexcel')->createWriter($phpExcelObject, 'Excel5');
// create the response
$response = $this->get('phpexcel')->createStreamedResponse($writer);
// adding headers
$dispositionHeader = $response->headers->makeDisposition(
ResponseHeaderBag::DISPOSITION_ATTACHMENT,
'stream-file.xls'
);
$response->headers->set('Content-Type', 'text/vnd.ms-excel; charset=utf-8');
$response->headers->set('Pragma', 'public');
$response->headers->set('Cache-Control', 'maxage=1');
$response->headers->set('Content-Disposition', $dispositionHeader);
return $response;
$output->writeln('done');
}

when you create a command by following docs your command class inherits ContainerAwareCommand class and you can get the container by calling $this->getContainer() inside the execute() function of your command class, once you have container you can access any service like to get the excel service you can get it like $this->getContainer()->get('phpexcel')
class GenerateExcelCommand extends ContainerAwareCommand
{
protected function configure()
{
//..............
}
protected function execute(InputInterface $input, OutputInterface $output)
{
$excelObj= $this->getContainer()->get('phpexcel');
// do your excel stuff here
$phpExcelObject = $excelObj->createPHPExcelObject('file.xls');
$writer = $excelObj->createWriter($phpExcelObject, 'Excel5');
$writer->save('file.xls');
$output->writeln('done');
}
}
By using ContainerAwareCommand as the base class for the command (instead of the more basic Command), you have access to the service container. In other words, you have access to any configured service
