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：＆＃39; 在插件管理器Zend \ Mvc \ Controller \ PluginManager中找不到名为“getServiceLocator”的插件/ EM>＆＃39 ;.为了解决这个问题，我发现了以下内容：A plugin by the name "getServiceLocator" was not found in the plugin manager Zend\Mvc\Controller\PluginManager这几乎完全符合我的情况。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

＆＃34;基本上，你不应该在中间注入依赖关系运行时，但实际上为您的控制器注册工厂然后通过构造函数传递依赖关系。＆＃34;

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：＆＃39; 无法解析服务＆＃34; BookList \ Controller \ Book＆＃34;到工厂;您确定在配置期间提供了它吗？＆＃39;。我无法理解为什么！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：

#0 C:\wamp64\www\skeleton-application\vendor\zendframework\zend-servicemanager\src\ServiceManager.php(763): Zend\ServiceManager\ServiceManager->getFactory('BookList\\Contro...') #1 C:\wamp64\www\skeleton-application\vendor\zendframework\zend-servicemanager\src\ServiceManager.php(200): Zend\ServiceManager\ServiceManager->doCreate('BookList\\Contro...') #2 C:\wamp64\www\skeleton-application\vendor\zendframework\zend-servicemanager\src\AbstractPluginManager.php(141): Zend\ServiceManager\ServiceManager->get('BookList\\Contro...') #3 C:\wamp64\www\skeleton-application\vendor\zendframework\zend-mvc\src\DispatchListener.php(102): Zend\ServiceManager\AbstractPluginManager->get('BookList\\Contro...') #4 C:\wamp64\www\skeleton-application\vendor\zendframework\zend-eventmanager\src\EventManager.php(322): Zend\Mvc\DispatchListener->onDispatch(Object(Zend\Mvc\MvcEvent)) #5 C:\wamp64\www\skeleton-application\vendor\zendframework\zend-eventmanager\src\EventManager.php(179): Zend\EventManager\EventManager->triggerListeners(Object(Zend\Mvc\MvcEvent), Object(Closure)) #6 C:\wamp64\www\skeleton-application\vendor\zendframework\zend-mvc\src\Application.php(332): Zend\EventManager\EventManager->triggerEventUntil(Object(Closure), Object(Zend\Mvc\MvcEvent)) #7 C:\wamp64\www\skeleton-application\public\index.php(40): Zend\Mvc\Application->run() #8 {main}

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')); } } ?>
模块\ BookList \ config \下的
module.config.php - 我用注释了＆＃39; Invokables＆＃39; 元素，替换了 >＆＃39;工厂＆＃39; 元素按照指示（在顶部）：

<?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' ) ) ) ) );

如果我的版本控制存在问题，那就是我用来安装ZF和Doctrine的Composer.json文件：

{ "name": "zendframework/skeleton-application", "description": "Skeleton Application for Zend Framework zend-mvc applications", "type": "project", "license": "BSD-3-Clause", "keywords": [ "framework", "mvc", "zf" ], "homepage": "http://framework.zend.com/", "minimum-stability": "dev", "prefer-stable": true, "require": { "php": "^5.6 || ^7.0", "zendframework/zend-component-installer": "^1.0 || ^0.7 || ^1.0.0-dev@dev", "zendframework/zend-mvc": "^3.1.0", "zfcampus/zf-development-mode": "^3.0", "zendframework/zftool": "dev-master", "doctrine/doctrine-orm-module": "^1.1" }, "autoload": { "psr-4": { "Application\\": "module/Application/src/" } }, "autoload-dev": { "psr-4": { "ApplicationTest\\": "module/Application/test/" } }, "extra": [], "scripts": { "cs-check": "phpcs", "cs-fix": "phpcbf", "development-disable": "zf-development-mode disable", "development-enable": "zf-development-mode enable", "development-status": "zf-development-mode status", "post-create-project-cmd": [ "@development-enable" ], "serve": "php -S 0.0.0.0:8080 -t public public/index.php", "test": "phpunit" } }

看起来您在控制器工厂中错误地标记了该类。在module.config.php中，您调用工厂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'));
    }
}

?>

Zend 3＆amp; Doctrine无法解析服务＆＃34; BookList \ Controller \ Book＆＃34;到工厂;您确定在配置期间提供了它吗？
