configuration - Zend 框架 2：如何从模型中获取自定义配置？

Question

在我的应用程序中，有自定义配置，我想将它们放入模型中。

我读到了一种方法，但它不能执行：

namespace Core\Model;

use Zend\Db\TableGateway\AbstractTableGateway;
use Zend\Db\TableGateway\Feature\FeatureSet;
use Zend\Db\TableGateway\Feature\GlobalAdapterFeature;
use Zend\Db\Sql\Delete,
    Zend\Db\Sql\Insert,
    Zend\Db\Sql\Update,
    Zend\Db\Sql\Select;

use Zend\ServiceManager\ServiceLocatorAwareInterface;
use Zend\ServiceManager\ServiceLocatorInterface;

class BaseModel extends AbstractTableGateway implements ServiceLocatorAwareInterface
{

    protected $serviceLocator;

    public function setServiceLocator(ServiceLocatorInterface $serviceLocator) {
        $this->serviceLocator = $serviceLocator;
    }

    public function getServiceLocator() {
        return $this->serviceLocator;
    }

    public function __construct()
    {
        $this->featureSet = new FeatureSet();
        $this->featureSet->addFeature(new GlobalAdapterFeature());
        $this->initialize();
    }
}

在我规定的模型中

$config = $this->getServiceLocator()->get('config');

或者

$config = $this->getServiceLocator();

但结果=NULL

谁能告诉我我做错了什么？

您必须创建BaseModel使用 ServiceManager 扩展的类的实例。如果使用new，则必须自己设置 ServiceManager。
