Use custom annotations in Symfony User Provider - php

Question

I'm trying to make a custom User Provider which uses a custom Doctrine-like bundle. This bundles uses entities, pretty much like Doctrine does :
/**
* #EntityMeta(table="MY_TABLE")
*/
class MyTable extends AbstractEntity
{
/**
* #var int
* #EntityColumnMeta(column="Code", isKey=true)
*/
protected $code;
/**
* #var int
* #EntityColumnMeta(column="Name")
*/
protected $name;
Those annotations work well when I use the doctrine-like manager provided by my bundle. This code works well :
public function indexAction(DoctrineLikeManager $manager)
{
$lines = $manager->getRepository('MyTable')->findBy(array(
'email' => 'test#test.com'
));
// do something with these
}
So I know annotations work. But when I use the same code, with the same entity, in the User Provider Class, I get the following error :
[Semantical Error] The annotation "#NameSpace\DoctrineLikeBundle\EntityColumnMeta" in property AppBundle\MyTable::$code does not exist, or could not be auto-loaded.
The UserProvider :
class HanaUserProvider implements UserProviderInterface
{
private $manager;
public function __construct(DoctrineLikeManager $manager)
{
$this->manager = $manager;
}
public function loadUserByUsername($username)
{
// this is where it fails :(
$lines = $this->manager->getRepository('MyTable')->findBy(array(
'email' => 'test#test.com'
));
// return user or throw UsernameNotFoundException
}
}
Is it possible to use custom annotations in that context ? Maybe I should do something in particular so custom annotations can be successfully loaded ?
Thanks in advance !

Answer 1

Ok, I found a solution, which might not be the best but works.
The thing is that annotations don't seem to use classic autoloading, as explained here.
I had to register a loader in my User Provider :
public function loadUserByUsername($username)
{
AnnotationRegistry::registerLoader('class_exists'); // THIS LINE HERE
$lines = $this->manager->getRepository('MyTable')->findBy(array(
'email' => 'test#test.com'
));
// return user or throw UsernameNotFoundException
}
However, the problem is that this method is deprecated and will be removed in doctrine/annotations 2.0.
