Doctrine2 - 「類」不是有效的實體或映射超類

每次我得到異常Uncaught exception 'Doctrine\ORM\Mapping\MappingException' with message 'Class "Users" is not a valid entity or mapped super class當我運行下面的代碼：Doctrine2 - 「類」不是有效的實體或映射超類

test.php的

<?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);

你有什麼想法麼？ eAccelerator未設置。學說v 2.2，PHP v 5.3.22，zend引擎2.3.0

我不認爲它需要按順序，但我總是先把'@ORM \ Entity'表示法，你有沒有試過？你有其他工作實體加載好嗎？也無關...這個類代表一個單一的「用戶」實體，所以它最好使用單數的類名（即用戶）。 – prodigitalson 2013-02-26 21:04:52

這沒有幫助:(。我有更多的實體，但我有他們所有的同樣的問題......這可能是一個簡單的問題，但我找不到什麼是錯的 – KennyPowers 2013-02-26 21:07:59

我沒有用過D2多在Symfony2之外...'Setup :: createAnnotationMetadataConfiguration'是否註冊了註釋？ – prodigitalson 2013-02-26 21:09:50

您正在使用Doctrine\Common\Annotations\SimpleAnnotationReader而不是Doctrine\Common\Annotations\AnnotationReader。

的SimpleAnnotationReader作品與默認名稱空間和讀取格式@Entity註解，而AnnotationReader可以使用導入的類和命名空間（通過use statement）和註釋如@ORM\Entity。

您可以在documentation上閱讀更多關於此的內容。

這是你的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);

它的工作原理！非常感謝！ – KennyPowers 2013-02-27 12:23:39

Doctrine 2.3的Setup :: createAnnotationMetadataConfiguration有一個名爲$ useSimpleAnnotationReader的第五個參數，您可以通過false來使其工作！ – Malte 2013-05-01 21:00:00

拯救生命。作爲新學說的人士，這非常有幫助。 – 2013-06-15 02:58:27

您可以使用配置的固定版本，只提供虛假的用簡單的註釋讀者，這樣的。

<?php 

//same code 

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

//same 
?>

在我而言，我只是忘了補充@ORM\Entity，像這樣：

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

就我而言，我是因爲我有/***代替/**打開了文檔塊收到此錯誤：

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

而我有'/ *'而不是'/ **'。謝謝！ – deltab 2016-10-07 13:17:24

以下是奧克拉米烏斯的回答（也拯救了我）

如果你有你的實體一些自定義命名空間確保註釋來命名空間decleration後，這裏是我的實體，它的工作：

<?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;

然後在我的控制器：

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

成功！
