Zend 3 & Doctrine 无法解析服务 "BookList\Controller\Book" 到工厂；你确定你在配置过程中提供了它吗？

Question

我正在尝试使用 Zend 和 Doctrine 创建一个练习项目。我可以让这个应用程序在没有 Doctrine 或数据库的情况下工作。

但是，最近我尝试使用 Doctrine 添加数据库层并开始收到错误消息：'在插件管理器中找不到名为“getServiceLocator”的插件Zend\Mvc\Controller\PluginManager'。为了解决这个问题，我发现了以下内容：这几乎完全符合我的情况。该解决方案表明 getServiceLocator() 已被删除，我需要使用 Factory 类来实例化我的控制器

"Basically, you shouldn't inject dependencies in the middle of runtime, but actually register a factory for your controller and then pass dependencies in through a constructor."

这是我的问题： 在实施上面提供的解决方案后，我收到以下错误：'无法将服务 "BookList\Controller\Book" 解析为工厂;您确定您在配置期间提供了它吗？'。我不知道为什么！我究竟做错了什么？为什么我会收到此错误以及为什么上述解决方案对我不起作用？

这是堆栈：

#7 C:\wamp64\www\skeleton-application\public\index.php(40): Zend\Mvc\Application->run()

我的控制器：

<?php
namespace BookList\Controller;

use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use BookList\Form\BookForm;
use Doctrine\ORM\EntityManager; //For DOCTRINE

class BookController extends AbstractActionController{

    protected $em; //DOCTRINE Entity Manager

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

    public function indexAction(){
        return new ViewModel(array(
            'books' => []; //Do nothing whilst I try to fix factory problem
        ));
    }

}

我的控制器工厂：

<?php
namespace BookList\Controller\Factory;

use Interop\Container\ContainerInterface;
use Zend\ServiceManager\Factory\FactoryInterface;
use BookList\Controller\BookController;

class IndexControllerFactory implements FactoryInterface {
    public function __invoke(ContainerInterface $container, $requestedName = "", array $options = null) {
        return new BookController($container->get('Doctrine\ORM\EntityManager'));
    }
}

?>

module.config.php under module\BookList\config\ - 我注释掉了 'Invokables' 元素和 replaced按照指示（在顶部）使用 'factories' 元素：

<?php
namespace BookList;

return array(
        'controllers' => array(
            /*
            'invokables' => array(
                'BookList\Controller\Book' => 'BookList\Controller\BookController',
            ),
            */
            'factories' => array(
                'BookList\Controller\Book' => 'BookList\Controller\Factory\BookListControllerFactory',
            ),

        ),
        'router' => array(
            'routes' => array(
                'book' => array(
                    'type' => 'segment',
                    'options' => array(
                        'route' => '/book[/][:action][/:id]',
                        'constraints' => array(
                            'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
                            'id'     => '[0-9]+',
                            ),
                            'defaults' => array(
                                'controller' => 'BookList\Controller\Book',
                                'action'     => 'index',
                            ),
                        ),
                    ),
                ),
            ),
            'view_manager' => array(
                'template_path_stack' => array(
                    'book' => __DIR__ . '/../view',
                ),
            ),
        // Doctrine config
        'doctrine' => array(
            'driver' => array(
                __NAMESPACE__ . '_driver' => array(
                    'class' => 'Doctrine\ORM\Mapping\Driver\AnnotationDriver',
                    'cache' => 'array',
                    'paths' => array(__DIR__ . '/../src/' . __NAMESPACE__ . '/Entity')
                ),
                'orm_default' => array(
                    'drivers' => array(
                        __NAMESPACE__ . '\Entity' => __NAMESPACE__ . '_driver'
                    )
                )
            )
        )
);

您似乎在控制器工厂中给 class 贴上了错误的标签。在 module.config.php 中，您将工厂称为 BookListControllerFactory，但在控制器工厂中，您将其称为 IndexControllerFactory。试试这个：

<?php
namespace BookList\Controller\Factory;

use Interop\Container\ContainerInterface;
use Zend\ServiceManager\Factory\FactoryInterface;
use BookList\Controller\BookController;

class BookListControllerFactory implements FactoryInterface {
    public function __invoke(ContainerInterface $container, $requestedName = "", array $options = null) {
        return new BookController($container->get('Doctrine\ORM\EntityManager'));
    }
}

?>
