PHP-DI 无法与 ZendFramework2 集成

Question

你能给我一个提示，为什么 PHP-DI integration with Zend Framework 2 对我不起作用（转载于 Apache/2.4.9 (Win64) PHP/5.5.12 和 Apache/2.2.22 (Win32) PHP/5.3.13).

composer.json:

{
    "require": {
        "php": ">=5.3.3",
        "zendframework/zendframework": "2.3.5",
        "mnapoli/php-di": "4.4.6",
        "mnapoli/php-di-zf2": "0.3.0",
       ...
},
    ...

config\application.config.php:

<?php
return array(
    'modules' => array(
        'Morpho',
        'DI\ZendFramework2',
    ),
    'module_listener_options' => array(
        'module_paths' => array(
            './module',
            './vendor',
        ),
    ),
);
?>

module/Morpho/config.module.config.php:

<?php
return array(
    'service_manager' => array(
        'factories' => array(
            'DI\Container' => function() {
                $builder = new DI\ContainerBuilder();
                $builder->addDefinitionsFromFile("config/di.yml");
                return $builder->build();
            },
        ),
    ),
    'router' => array(
        ...
    ),
    'controllers' => array(
        ...
    ),
    'view_manager' => array(
        ...
    ),
);

config/di.yml:

Morpho\Service\PartOfSpeechService:
    class: Morpho\Service\PhpMorphyPartOfSpeechService

module/Morpho/src/Morpho/Controller/PartOfSpeechController:

class PartOfSpeechController extends AbstractRestfulController {
    ...
    /**
     * @Inject
     * @var PartOfSpeechService
     */
    public $partOfSpeechService;

    public function processPostData(Request $request) {
        $partsOfSpeech = $this->partOfSpeechService->getPartsOfSpeech("test", "en_EN");
        return new JsonModel($partsOfSpeech);
    }
}

当运行这段代码在apache下我每次得到：

PHP Fatal error:  Uncaught exception 'Zend\ModuleManager\Exception\RuntimeException'
with message 'Module (DI\ZendFramework2) could not be initialized.' in \vendor\zendframework\zendframework\library\Zend\ModuleManager\ModuleManager.php:195
Stack trace:

2 [internal function]: Zend\ModuleManager\ModuleManager->onLoadModules(Object(Zend\ModuleManager\ModuleEvent))
3 \vendor\zendframework\zendframework\library\Zend\EventManager\EventManager.php(468):

4 \vendor\zendframework\zendframework\library\Zend\EventManager\EventManager.php(207): Zend\EventM in \vendor\zendframework\zendframework\library\Zend\ModuleManager\ModuleManager.php on line 195

如有任何想法，我们将不胜感激。

我遵循了 Purple Hexagon 给出的建议，这里是使用服务管理器的有效实现：

module/Morpho/config:

...
'service_manager' => array(
    'services' => array(
        "PartOfSpeechService" => new Morpho\Service\PhpMorphyPartOfSpeechService(),
    ),
),
...

module/Morpho/src/Morpho/Controller/PartOfSpeechController.php:

class PartOfSpeechController extends AbstractRestfulController {
    ...
    public function processPostData(Request $request) {
        $serviceManager = $this->getServiceLocator();
        $partsOfSpeech = $serviceManager->get("PartOfSpeechService")->getPartsOfSpeech($request->getPost("phrase"),
                $request->getPost("language"));
        return new JsonModel($partsOfSpeech);
    }
}

为什么我不喜欢这个：

我必须使用 "dummy" 代码来获取 serviceManager。那是 "dummy"，因为它与我的应用程序的业务逻辑完全无关。
ServiceManager 提供的依赖注入方法使我的代码依赖于 ServiceManager 本身。通常我不应该关心 bean/object 是如何注入的，因此不应该在我的代码中引用任何类型的容器或 ServiceManager。

我认为 PHP-DI 更接近 Java Spring 使用的 bean 注入模型（我认为这很好）。不幸的是它仍然不适合我。最后，从容器中获取对象的方法也适用于 PHP-DI。

对于服务：

出厂配置：

        'factories' => array(
            'MyService' => 'Application\Factory\MyService',
        ),

工厂class:

class MyService implements FactoryInterface
{

    public function createService(ServiceLocatorInterface $serviceManager)
    {
        $purifier = new MyService($serviceManager->get('MyAwesomeDependency'));
        return $purifier;
    }
}

对于控制器：

ControllerFactory.php:

class PartOfSpeechControllerFactory
{
    public function __invoke($serviceLocator)
    {
        // Service locator here is the ControllerManager so get ServiceManager 
        $serviceManager = $serviceLocator->getServiceLocator();

        $controller = new PartOfSpeechController($serviceManager->get('PartOfSpeechService'));

        return $controller;
    }
}

class PartOfSpeechController.php

class PartOfSpeechController extends AbstractRestfulController {


    protected $partOfSpeechService;

    public function __construct(PartOfSpeechService $partOfSpeechService)
    {
         $this->partOfSpeechService = $partOfSpeechService;
    }


    public function processPostData(Request $request) {
         $var = $this->partOfSpeechService->serviceMethod();   
    }
}

控制器配置：

'factories' => array(
                'Application\Controller\PartOfSpeechController' => 'Application\Factory\PartOfSpeechControllerFactory'
        ),

它不起作用，因为您使用的是旧的 YAML 语法，但是 since PHP-DI v4.0 the syntax is now PHP。

前往文档了解语法：http://php-di.org/doc/definition.html
