Doctrine2 - “class” is not a valid entity or mapped super class

Question

I get exception Uncaught exception \'Doctrine\\ORM\\Mapping\\MappingException\' with message \'Class \"Users\" is not a valid entity or mapped super class every

Answer 1

You are using a Doctrine\Common\Annotations\SimpleAnnotationReader instead of a Doctrine\Common\Annotations\AnnotationReader.

The SimpleAnnotationReader works with default namespaces and reads annotations in format @Entity, while the AnnotationReader can use the imported classes and namespaces (via use statement) and annotations such as @ORM\Entity.

You can read more about that on the documentation.

Here's a fixed version of your test.php

 'pdo_mysql',
    'user'     => 'root',
    'password' => 'pass',
    'dbname'   => 'dbname',
);

$config = Setup::createConfiguration($isDevMode);
$driver = new AnnotationDriver(new AnnotationReader(), $paths);

// registering noop annotation autoloader - allow all annotations by default
AnnotationRegistry::registerLoader('class_exists');
$config->setMetadataDriverImpl($driver);

$em = EntityManager::create($connectionParams, $config);

$user = $em->find('Users', 5);
