提问by KennyPowers

I get exception Uncaught exception 'Doctrine\ORM\Mapping\MappingException' with message 'Class "Users" is not a valid entity or mapped super classevery time when I run the next code:

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

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

You are using a Doctrine\Common\Annotations\SimpleAnnotationReaderinstead of a Doctrine\Common\Annotations\AnnotationReader.

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

The SimpleAnnotationReaderworks with default namespaces and reads annotations in format @Entity, while the AnnotationReadercan use the imported classes and namespaces (via usestatement) and annotations such as @ORM\Entity.

该SimpleAnnotationReader默认命名空间工程和格式读取的注释@Entity，而AnnotationReader可以使用进口类和命名空间（通过use声明）和注释等@ORM\Entity。

You can read more about that on the documentation.

您可以在文档中阅读更多相关信息。

Here's a fixed version of your test.php

这是你的固定版本 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);

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

就我而言，我只是忘了添加@ORM\Entity，如下所示：

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

回答by Oleg Abrazhaev

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

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，就像这样。

<?php

//same code

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

//same
?>

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

就我而言，我收到此错误是因为我打开了文档块/***而不是/**：

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

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

按照奥克拉米乌斯的回答（这也救了我）

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:

如果您的实体上有一些自定义命名空间，请确保注释在命名空间声明之后出现，这是我的实体有效：

<?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:

然后在我的控制器中：

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

Success!

成功！
