php - Doctrine2 - "class" is not a valid entity or mapped super class

Question

I get exception Uncaught exception 'DoctrineORMMappingMappingException' 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 DoctrineORMToolsSetup;
use DoctrineORMEntityManager;

$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 DoctrineCommonAnnotationsSimpleAnnotationReader instead of a DoctrineCommonAnnotationsAnnotationReader.

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 @ORMEntity.

You can read more about that on the documentation.

Here's a fixed version of your test.php

<?php

use DoctrineORMToolsSetup;
use DoctrineORMEntityManager;
use DoctrineORMMappingDriverAnnotationDriver;
use DoctrineCommonAnnotationsAnnotationReader;
use DoctrineCommonAnnotationsAnnotationRegistry;

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);
