Php 获取实体元数据

我试图从条令实体中读取注释元数据，以便实例化自定义存储库：

$userRepository = new \My\Repository\UserRepository( $entityManager, $classMetadata );

要获取

$classMetadata

，我有以下几点：

$userRepository = $entityManager->getRepository('\My\Entity\User');

我的

用户

实体：

namespace My\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity(repositoryClass="My\Repository\UserRepository")
 * @ORM\Table(name="users")
 */
class User {

    /**
     * @ORM\Column(name="user_id", type="integer", nullable=false)
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="IDENTITY")
     */
    protected $id;

    public function getId()
    {
        return $this->id;
    }

    public function setId( $id )
    {
        $this->id = $id;

        return $this;
    }

}

我的

UserRepository

：

namespace My\Repository;

use Doctrine\ORM\EntityRepository;

class UserRepository extends EntityRepository {

}

我的主要剧本：

require '../vendor/autoload.php';

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

$paths = array('../src/My/Entity');
$isDevMode = TRUE;

// the connection configuration
$dbParams = array(
    'driver'   => 'pdo_mysql',
    'dbname'   => 'mydb',
    'user'     => 'myuser',
    'password' => 's3cr3t',
);

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

$classMetadata = $entityManager->getClassMetadata('\My\Entity\User');

但我一直得到以下错误：

PHP Fatal error:  Uncaught exception 'Doctrine\ORM\Mapping\MappingException' with message 'Class "My\Entity\User" is not a valid entity or mapped super class.' in vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/MappingException.php:216

我错过了什么

更新：

我尝试了以下方法：

$userRepository = $entityManager->getRepository('\My\Entity\User');

但我也犯了同样的错误

更新2:

我已经按照条令教程[1]中所述设置了

bootstrap.php

和

cli config.php

文件，现在可以运行

bin/doctor

命令行实用程序。有趣的结果：

bin/doctrine orm:validate-schema

输出：

[Mapping]  OK - The mapping files are correct.
[Database] OK - The database schema is in sync with the mapping files.

[Exception]                                                                                                                                                                             
You do not have any mapped Doctrine ORM entities according to the current configuration. If you have entities or mapping files you should check your mapping configuration for errors.

但当我这样做的时候：

bin/doctrine orm:info

输出：

[Mapping]  OK - The mapping files are correct.
[Database] OK - The database schema is in sync with the mapping files.

[Exception]                                                                                                                                                                             
You do not have any mapped Doctrine ORM entities according to the current configuration. If you have entities or mapping files you should check your mapping configuration for errors.

有什么想法吗
