    $moduleRouteListener = new ModuleRouteListener();
    $moduleRouteListener->attach($eventManager);

    // 以下を追加
    $sm = $e->getApplication()->getServiceManager();
    $translator = $sm->get('MvcTranslator');
    $translator->addTranslationFile(
        'phpArray',
        'vendor/zendframework/zendframework/resources/languages/ja/' .
        'Zend_Validate.php',
        'default',
