PHP-DI无法与ZendFramework2集成

Question

您能给我一个提示吗？为什么PHP-DI与Zend Framework 2的集成不适合我（使用Apache/2.4.9（Win64）PHP/5.5.12和Apache/2.2.22（Win32）PHP/5.3.13复制）。

创作者json:

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

配置\应用程序。配置。php:

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

模块/Morpho/config。单元配置。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

模块/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);
    }
}

每次在apache下运行此代码时，我得到：

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

我遵循了Purple Hexagon的建议，下面是一个使用Service Manager的工作实现：

模块/Morpho/配置：

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

模块/Morpho/src/Morpho/控制器/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：

1. 我必须使用“虚拟”代码来获取serviceManager。这是“虚拟的”，因为它和我的应用程序的业务逻辑根本不相关

我认为PHP-DI更接近JavaSpring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在PHP-DI中工作。

对于服务：

工厂配置：

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

工厂等级：

class MyService implements FactoryInterface
{

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

对于控制器：

控制器工厂。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;
    }
}

类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();   
    }
}

控制器的配置：

'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，而是PHP-DI v4。0语法现在是PHP。

请参阅文档了解语法：http://php-di.org/doc/definition.html
