How to use Doctrine outside of Symfony?

Question

symfony

Hello!
There is a project on Symfony and there is a separate php application.
I would like to use common Entities to interact with the database, but not put the application in the Symfony structure. How to implement it correctly?
The php application is located in the source folder
(full path _project_/src/worker/application.php).
Tried to do like this:

require __DIR__.'/../../vendor/autoload.php';
use Doctrine\ORM\Tools\Setup;
use Doctrine\ORM\EntityManager;
use App\Entity\Account; // Подключаю объект account, который прекрасно работает из Symfony

$isDevMode = true;
$entitiesPaths = array(__DIR__.'/../Entity');
$dbParams = array(
    'dbname' => '_база_',
    'user' => '_логин_',
    'password' => '_пароль_',
    'host' => '127.0.0.1',
    'driver' => 'pdo_mysql',
);
$config = Setup::createAnnotationMetadataConfiguration($entitiesPaths, $isDevMode);
$em = \Doctrine\ORM\EntityManager::create($dbParams, $config);
$id = 9; // для примера
$account = $em->getRepository(Account::class)->findOneBy([
'id'=>$id,
]);
var_dump($account);
//Дальше идёт код приложения

But I get an error:
Class "App\Entity\Account" is not a valid entity or mapped super class.
That being said App\Entity\Account is formed with php bin/console make:entity and works well from symfony controllers

Answer 1

Setup::createAnnotationMetadataConfiguration($entitiesPaths, $isDevMode, null, null, false);

for doctrine up to version 3.0 (in the third version, it seems to be done according to normal). Most likely, the problem is that in a Symfony project you write something like in the annotations @ORM\Entity, and for this, a pure doctrine needs to slip a normal AnnotationReader, and not Simple, which is created by default.

1. Create a composer package with shared entities
   There are also git submodules, but this is a more crutch option
