在 Zend3 项目中集成 Doctrine 的问题

Question

离开Zend很久后，我需要再次回到它。 我上一次在Zend Framework上的工作是在2016年。现在我试图用教义安装 Zend Framework 3 并陷入困境。

我做了什么：

使用作曲家构建骨架应用

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框架：

composer self-update
composer install

我启动机器并输入：vagrant up && vagrant ssh

我需要原则require doctrine/doctrine-orm-module并在 module.config 中对其进行配置.php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 ApplicationControllerFactory;
use ApplicationEntityUser;
use InteropContainerContainerInterface;
use ZendServiceManagerFactoryFactoryInterface;
use ApplicationControllerIndexController;
/**
* 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);
}
}

将实体添加到代码库：

namespace ApplicationEntity;
/**
* @ORMEntity
* @ORMTable(name="user")
*/
class User
{
/**
* @ORMId
* @ORMGeneratedValue
* @ORMColumn(name="id")
*/
protected $id;
/**
* @ORMColumn(name="nick")
*/
protected $nick; 
....
}

我尝试使用此实体通过教义创建 mysql 表：

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

表未创建，我收到此错误：

"没有要处理的元数据类。">

我试图测试教义：

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

它似乎正在工作：

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

还尝试在控制器中加载我手动创建的表：

class IndexController extends AbstractActionController
{
/**
* Doctrine entity manager.
* @var DoctrineORMEntityManager
*/
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('ApplicationEntityUser')->findAll();
return new ViewModel();
}
}

这导致了以下错误：

有人可以给我一个提示，我错过了什么吗？

Answer 1

看起来您没有定义应该在哪里找到实体。

下面是代码中缺失位的链接：

Answer 2

乍一看，您的错误似乎告诉我们他找不到"应用程序\实体\用户"。 一开始，Doctrine 对你的命名空间一无所知。 Doctrine 使用注释驱动程序来获取有关实体位置的通知。 因此，在步骤 5(指定 module.config.php)中，您需要将以下代码添加到组合中：

<?php
namespace Application;
use DoctrineORMMappingDriverAnnotationDriver;
return [
// ...
'doctrine' => [
'driver' => [
__NAMESPACE__ . '_driver' => [
'class' => AnnotationDriver::class,
'cache' => 'array',
'paths' => [__DIR__ . '/../src/Entity']
],
'orm_default' => [
'drivers' => [
__NAMESPACE__ . 'Entity' => __NAMESPACE__ . '_driver'
]
]
]
]  
];

当然，您需要设置到设置的路径。
