Question

我有这样的代码：

        $sessionOptions = new SessionDbSavehandlerOptions();
        $sessionOptions->setDataColumn('data')
                       ->setIdColumn('id')
                       ->setModifiedColumn('modified')
                       ->setLifetimeColumn('lifetime')
                       ->setNameColumn('name');
        $application    = $event->getApplication();
        $serviceManager = $application->getServiceManager();
        $dbAdapter = $serviceManager->get('Zend\Db\Adapter\Adapter');
        $sessionTableGateway = new TableGateway('zf2_sessions', $dbAdapter);
        $sessionGateway = new DbTableGateway($sessionTableGateway, $sessionOptions);
        $config = $serviceManager->get('Configuration');
        $sessionConfig = new SessionConfig();
        $sessionConfig->setOptions($config['session']);
        $sessionManager = new SessionManager($sessionConfig);
        $sessionManager->setSaveHandler($sessionGateway);
        $sessionManager->start();
        Container::setDefaultManager($sessionManager);

效果很好，但此代码位于onBootstrap()文件中的Module.php方法中。是否有更好的方法（地点？）来实现会话？控制器插件适用于Controller，那么这些是什么？

我的建议是将其作为专用的低级模块。您可以将完整的配置和实例化封装到一个简单的模块中，您可以依赖该模块进行进一步的应用。

与我们处理mail，logging和cache完全相同（虽然缓存尚未完成）。在这些情况下，我们创建可以在应用程序服务中注入的服务。在你的情况下，我会把它作为一个监听器（在专用类中封装或不在你的onBootstrap()方法中进行初始化。

一个小例子：

namespace MySession;

use Zend\Session\Container;

class Module
{
    public function onBootstrap($e)
    {
        $app = $e->getApplication();
        $sm  = $app->getServiceManager();

        $manager = $sm->get('session_manager');
        $manager->start();

        Container::setDefaultManager($manager);
    }

    public function getServiceConfig()
    {
        return array(
            'factories' => array(
                'session_manager' => 'MySession\Service\SessionManagerFactory'
            ),
        );
    }
}

并将会话管理器的工厂逻辑封装在工厂类中：

namespace MySession\Service;

use Zend\ServiceManger\FactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;

// Your imports further here

class SessionManagerFactory implements FactoryInterface
{
    public function createService(ServiceLocatorInterface $sl)
    {
        $sessionOptions = new SessionDbSavehandlerOptions();
        $sessionOptions->setDataColumn('data')
                       ->setIdColumn('id')
                       ->setModifiedColumn('modified')
                       ->setLifetimeColumn('lifetime')
                       ->setNameColumn('name');
        $application    = $event->getApplication();
        $serviceManager = $application->getServiceManager();
        $dbAdapter = $serviceManager->get('Zend\Db\Adapter\Adapter');
        $sessionTableGateway = new TableGateway('zf2_sessions', $dbAdapter);
        $sessionGateway = new DbTableGateway($sessionTableGateway, $sessionOptions);
        $config = $serviceManager->get('Configuration');
        $sessionConfig = new SessionConfig();
        $sessionConfig->setOptions($config['session']);
        $sessionManager = new SessionManager($sessionConfig);
        $sessionManager->setSaveHandler($sessionGateway);

        return $sessionManager;
    }
}
