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 time when I run the next code:

test.php

<?php
require_once "vendor/autoload.php";

use Doctrine\ORM\Tools\Setup;
use Doctrine\ORM\EntityManager;

$paths = array(dirname(__FILE__)."/entities");
$isDevMode = false;

// the connection configuration
$dbParams = array(
    'driver'   => 'pdo_mysql',
    'user'     => 'root',
    'password' => 'pass',
    'dbname'   => 'snabcentr',
);

$config = Setup::createAnnotationMetadataConfiguration($paths, $isDevMode);
$em = EntityManager::create($dbParams, $config);

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

Do you have any ideas why? eAccelerator is not set up. Doctrine v 2.2, PHP v 5.3.22, zend engine 2.3.0

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

<?php

use Doctrine\ORM\Tools\Setup;
use Doctrine\ORM\EntityManager;
use Doctrine\ORM\Mapping\Driver\AnnotationDriver;
use Doctrine\Common\Annotations\AnnotationReader;
use Doctrine\Common\Annotations\AnnotationRegistry;

require_once __DIR__ . '/vendor/autoload.php';
require_once __DIR__ . '/entities/Users.php';

$paths            = array(__DIR__ . '/entities');
$isDevMode        = false;
$connectionParams = array(
    'driver'   => '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);

Answer 2

In my case, I just forgot to add @ORM\Entity, like this:

/**
 * Project\BackendBundle\Entity\Pedido
 *
 * @ORM\Table
 * @ORM\Entity
 * @ORM\HasLifecycleCallbacks
 */
class Pedido

Answer 3

In my case, I received this error because I opened the doc block with /*** instead of /**:

/***
 * @entity
 * @table(name="bans")
 */

Answer 4

You can use your configuration, just provide FALSE to use simple annotation reader, like that.

<?php

//same code

$isSimpleMode = FALSE;
$proxyDir = null;
$cache = null;
$config = Setup::createAnnotationMetadataConfiguration(
$paths, $isDevMode, $proxyDir, $cache, $isSimpleMode
);

//same
?>

Answer 5

Following to Ocramius's answer (which saved me as well)

If you've got some custom namespacing on your Entities make sure that the annotations come after the namespace decleration, here is my Entity that worked:

<?php


namespace App\Models;

/**
  * Books
  *
  * @ORM\Table(name="books")
  * @ORM\Entity
  */

  use Doctrine\ORM\Mapping as ORM;


  class Books
  {
  /**
   * @var integer
   *
   * @ORM\Column(name="id", type="integer", nullable=false)
   * @ORM\Id
   * @ORM\GeneratedValue(strategy="IDENTITY")
   */
  private $id;

  /**
   * @var string
   *
   * @ORM\Column(name="name", type="string", length=20, nullable=true)
   */
  private $name;

  /**
   * @var string
   *
   * @ORM\Column(name="isbn", type="string", length=20, nullable=true)
   */
  private $isbn;

Then in my controller:

   $entityManager->find('App\Models\Books', 1)

Success!
