Question

离Zend很长一段时间后，我需要再次回到它。我在Zend Framework上的最后一项工作是在2016年。现在我尝试使用doctrine安装Zend Framework 3并且卡住了。

我做了什么：

使用composer构建骨架应用

composer create-project -s dev zendframework/skeleton-application path/to/install

没有使用最小安装，并在所有选项上说y。更新了作曲家并安装了Zend Framework：

composer self-update
composer install

我启动了机器并输入了它：vagrant up && vagrant ssh

我需要doctrine require doctrine/doctrine-orm-module并在module.config.php中配置它，如下所示：

'doctrine' => [
    'connection' => [
        'orm_default' => [
            'driverClass' => PDOMySqlDriver::class,
            'params' => [
                'host'     => '127.0.0.1',
                'user'     => 'root',
                'password' => 'r00t',
                'dbname'   => 'zftest',
            ]
        ],
    ],
],

然后我写了一个控制器工厂来注入实体管理器：

namespace Application\Controller\Factory;

use Application\Entity\User;
use Interop\Container\ContainerInterface;
use Zend\ServiceManager\Factory\FactoryInterface;
use Application\Controller\IndexController;

/**
 * This is the factory for IndexController. Its purpose is to instantiate the
 * controller.
 */
class IndexControllerFactory implements FactoryInterface
{
    public function __invoke(ContainerInterface $container,
                             $requestedName, array $options = null)
    {
        $entityManager = $container->get('doctrine.entitymanager.orm_default');

        // Instantiate the controller and inject dependencies
        return new IndexController($entityManager);
    }
}

在代码库中添加了一个实体：

namespace Application\Entity;
/**
 * @ORM\Entity
 * @ORM\Table(name="user")
 */
class User
{
    /**
     * @ORM\Id
     * @ORM\GeneratedValue
     * @ORM\Column(name="id")
     */
    protected $id;

    /**
     * @ORM\Column(name="nick")
     */
    protected $nick; 
    ....
}

我尝试使用此实体通过doctrine创建mysql表：

./vendor/bin/doctrine-module orm:schema-tool:create

该表未创建，我收到此错误：

＆＃34;没有要处理的元数据类。＆＃34;

我试图测试学说：

./vendor/bin/doctrine-module orm:validate-schema

它似乎正在起作用：

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

还在控制器中尝试加载我手动创建的表：

class IndexController extends AbstractActionController
{

    /**
     * Doctrine entity manager.
     * @var Doctrine\ORM\EntityManager
     */
    private $entityManager;

    // Constructor is used to inject dependencies into the service.

    /**
     * IndexController constructor.
     * @param $entityManager
     */
    public function __construct($entityManager)
    {
        $this->entityManager = $entityManager;
    }

    public function indexAction()
    {
        $users = $this->entityManager->getRepository('Application\Entity\User')->findAll();
        return new ViewModel();
    }
}

导致以下错误：

有人能给我一些提示吗？

Answer 1

看起来您没有定义应该找到实体的位置。

以下是代码中缺失位的链接：

DoctrineORMModule Documentation

Answer 2

乍一看，您的错误似乎告诉我们他找不到'Application \ Entity \ User'。一开始，Doctrine对您的命名空间一无所知。 Doctrine使用AnnotationDriver了解实体的位置。因此，在指定module.config.php的第5步中，您需要将以下代码添加到组合中：

^(?=.*\S)(?!.*\d).*

当然，你需要设置路径到你的设置。
