Question

我想在Controller上设置EntitiesManager实例。我想在Controller上使用$ this-＆gt; em实例。这是我的配置：

module.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',
            ),
        ),
    ),
),

IndexController.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：调用非对象上的成员函数find（）”。似乎比EntityManager没有正确实例化。

我错过了什么？

谢谢！

你在模块配置

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，使用$ em字段和setEm方法

//..
protected $em;

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

Doctrine2 + Zend Framework 2 - EntitiesManager作为Controller中的变量
