Doctrine2 - “class”不是有效实体或映射超类

Question

每次运行下一个代码时，我都会遇到异常Uncaught exception 'Doctrine\ORM\Mapping\MappingException' with message 'Class "Users" is not a valid entity or mapped super class：

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);

你有什么想法吗？ eAccelerator未设置。 Doctrine v 2.2，PHP v 5.3.22，zend engine 2.3.0

Answer 1

您使用的是Doctrine\Common\Annotations\SimpleAnnotationReader而不是Doctrine\Common\Annotations\AnnotationReader。

SimpleAnnotationReader使用默认名称空间并以@Entity格式读取注释，而AnnotationReader可以使用导入的类和名称空间（通过use statement）和注释，如@ORM\Entity。

您可以在documentation上了解更多相关内容。

以下是test.php

的固定版本

<?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

在我的情况下，我忘了添加@ORM\Entity，就像这样：

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

Answer 3

您可以使用您的配置，只需提供FALSE即可使用简单的注释阅读器。

<?php

//same code

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

//same
?>

Answer 4

就我而言，我收到此错误是因为我使用/***而不是/**打开了文档块：

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

Answer 5

跟随Ocramius的回答（也救了我）

如果您的实体上有一些自定义命名空间，请确保在命名空间声明后添加注释，这是我的实体工作：

<?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;

然后在我的控制器中：

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

成功！
