Php ZF2-在Service Manager中加载模型
在我的模块配置文件中,我有这些行将库和模型加载到ServiceManager中,以便我可以在控制器中检索它们。您可以看到我的所有模型都需要相同的依赖关系。请问,如果没有这些重复的代码块,我如何注入它们?这在我看来是错误的,但我不知道如何为不同的库运行相同的代码行。还是我应该使用工厂?谢谢大家!Php ZF2-在Service Manager中加载模型,php,zend-framework2,servicemanager,Php,Zend Framework2,Servicemanager,在我的模块配置文件中,我有这些行将库和模型加载到ServiceManager中,以便我可以在控制器中检索它们。您可以看到我的所有模型都需要相同的依赖关系。请问,如果没有这些重复的代码块,我如何注入它们?这在我看来是错误的,但我不知道如何为不同的库运行相同的代码行。还是我应该使用工厂?谢谢大家!

在这种情况下,你应该考虑使用抽象工厂。请参阅下面的代码:
namespace Application\Model;
use Zend\ServiceManager\AbstractFactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
class AbstractModelFactory implements AbstractFactoryInterface
{
public function canCreateServiceWithName(ServiceLocatorInterface $serviceLocator, $name, $requestedName)
{
$requestedName = explode('\\', $requestedName);
if ((!isset($requestedName[0]) || $requestedName[0] != 'Application')
|| (!isset($requestedName[1]) || $requestedName[1] != 'Model'))
{
return false;
}
$modelName = $requestedName[2];
return class_exists('Application\Model\\'.$modelName);
}
public function createServiceWithName(ServiceLocatorInterface $serviceLocator, $name, $requestedName)
{
$requestedName = explode('\\', $requestedName);
$modelName = $requestedName[2];
$coreLibrary = $serviceLocator->get('Project\CoreLibrary');
$io = $serviceLocator->get('Project\IO');
$class = 'Application\Model\\'.$modelName;
return new $class($coreLibrary, $io);
}
}
然后像这样注册您的工厂:
'service_manager' => [
'abstract_factories' => [
'Application\Model\AbstractModelFactory'
]
]
您也可以使用初始值设定项:
public function getServiceConfig(){
return array(
'initializers' => array(
function ($instance, $sm) {
if($instance instanceof Model\CoreAndIOAwareInterface){
$coreLibrary = $serviceLocator->get('Project\CoreLibrary');
$io = $serviceLocator->get('Project\IO');
$instance->setCoreLibrary($coreLibrary);
$instance->setIO($io);
}
},
)
);
}
因此,您还应该创建接口:
interface CoreAndIOAwareInterface
{
public function setCoreLibrary(CoreLibrary $coreLibrary);
public function setIO(IO $io);
}
并在模型类中实现此接口。这取决于你怎么做。在我看来,最好的方法是创建抽象类,然后用具体类对其进行扩展
