thanks to @Onedev.Link and @arogachev for his answer.that gave me an idea and i solve the problem.

i solve the problem modyfing swiftmailer component, in Mailer.php added this:

use app\models\Administracion; //The model i needed for access bd
 class Mailer extends BaseMailer
{
...
...
//this parameter is for the config (web.php)
public $CustomMailerConfig = false;
...
...
...
/**
     * Creates Swift mailer instance.
     * @return \Swift_Mailer mailer instance.
     */
    protected function createSwiftMailer()
    {
        if ($this->CustomMailerConfig) {
            $model = new Administracion();

            $this->setTransport([
                'class' => 'Swift_SmtpTransport',
                'host' => $model->getSmtpHost(),
                'username' => $model->getSmtpUser(),
                'password' => $model->getSmtpPass(),
                'port' => $model->getSmtpPort(),
                'encryption' => $model->getSmtpEncryption(),
            ]);
        }

        return \Swift_Mailer::newInstance($this->getTransport());
    }

And in Web.php added this:

'mailer' => [ 
            'class' => 'yii\swiftmailer\Mailer',
            'enableSwiftMailerLogging' =>true,
            'CustomMailerConfig' => true, //if its true use the bd config else set the transport here
            'useFileTransport' => false,
],
