Zend Framework 2无法从mail.local.php加载配置

Question

我正在尝试从mail.local.php获取配置smtp，但我确实尝试过ServiceLoader getServiceLoader方法，但无法在助手类中找到获取配置的方法：

获得autoloadmail.local.php的最佳方法是什么，

namespace Helpers;

use ZendMail;
use ZendMailTransportSmtp as SmtpTransport;
use ZendMailTransportSmtpOptions;

class SendEmail
{
    public static function email($to = '', $recipientName = '', $template = '')
    {
        $transport = new SmtpTransport();
//        $options = new SmtpOptions(array(
//            'name' => 'smtp.mailtrap.io',
//            'host' => 'smtp.mailtrap.io',
//            'port' => 2525,
//            'connection_class' => 'crammd5',
//            'connection_config' => array(
//                'username' => 'f11f5a55fdfbf5',
//                'password' => '7780e1e7ee1cc5',
//            ),
//        ));

        $mail = new MailMessage();
        $html = new endMimePart($template);
        $html->type = 'text/html';
        $body = new endMimeMessage;
        $body->setParts(array($html));
        $mail->setBody($body);
        $mail->setFrom('admin@fonedoctors.com', 'Admin FoneDoctors');
        $mail->addTo($to, $recipientName);
        $mail->setSubject('Unpaid Invoices');

        $transport->setOptions($options);
        $transport->send($mail);
    }
}
