doctrine-orm - Doctrine2 + Zend Framework 2 - EntitiesManager 作为控制器中的变量

Question

我想在我的控制器上设置 EntityManager 实例。我希望在控制器上可以使用 $this->em 的实例。这是我的配置：

模块.config.php

[...]
'doctrine' => array(
    'driver' => array(
        'application_entities' => array(
            'class' =>'Doctrine\ORM\Mapping\Driver\AnnotationDriver',
            'cache' => 'array',
            'paths' => array(__DIR__ . '/../src/Application/Entity')
        ),
        'orm_default' => array(
            'drivers' => array(
                'Application\Entity' => 'application_entities'
            ),
        ),
    ),
),  
'di' => array(
    'instance' => array(
        'alias' => array(
            'application' => 'Application\Controller\IndexController',
        ),
        'Application\Controller\IndexController' => array(
            'parameters' => array(
                'em' => 'doctrine_em',
            ),
        ),
    ),
),

索引控制器.php

namespace Application\Controller;

use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use \Doctrine\ORM\EntityManager;

class IndexController extends AbstractActionController
{

protected $em;

public function setEm(EntityManager $em) {
    $this->em = $em;
    return $this;
}

public function indexAction() {
    $user1 = $this->em->find('\Application\Entity\User', 1);
    var_dump($user1->getFullname());
}

我收到此错误：“致命错误：在非对象上调用成员函数 find() ”。似乎 EntityManager 没有正确实例化。

我错过了什么？

谢谢！

• 您不需要模块配置中的任何内容

• 你编辑 Module.php，onbootstrap 函数

  public function onBootstrap(\Zend\EventManager\EventInterface $e) {
       $serviceManager = $e->getApplication()->getServiceManager();
       $em = $serviceManager;
  
       $controllerLoader = $serviceManager->get('ControllerLoader');
       $controllerLoader->addInitializer(function ($controller) use ($em) {
           if (method_exists($controller, 'setEm')) {
              $controller->setEm($em);
           }
       });
  }
  

• 控制器保持原样，带有 $em 字段和 setEm 方法

  //..
  protected $em;
  
  public function setEm(EntityManager $em) {
          $this->em = $em;
          return $this;
  }
  //..
