Zend 2:如何在Module.php中获取闭包接受参数?

edit: I should explain this is for an app that must use\authenticate to multiple dbs. I have all the DB adapters defined in my autoload config like this:

return array(
    'db' => array(
        //Default adapter retrieved with $sm->get('Zend\Db\Adapter\Adapter')
        'driver' => 'Pdo_Mysql',
        'dsn' => 'mysql:dbname=db1;host=myserver',
        'username' => $DBuser,
        'password' => $DBpass,
        //'driver_options' => array(
        //  PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
        //),
        'adapters' => array(
            'someDB' => array(
                'driver' => 'Pdo_Mysql',
                'dsn' => 'mysql:dbname=someDB;host=myserver',
                'username' => $DBuser,
                'password' => $DBpass,
            ),
            'someOtherDB' => array(
                'driver' => 'Pdo_Mysql',
                'dsn' => 'mysql:dbname=someOtherDB;host=myserver',
                'username' => $DBuser,
                'password' => $DBpass,
                'AppType' => 'myCustomProperty',
...

I have the following function I'm trying to move to the service manager:

public function getAuthService($db) {
    if (! $this->authService) {
        //All DBs using authentication must have a view_users view
        $dbAdapter = $this->getServiceLocator()->get($db);
        $authAdapter = new AuthAdapter($dbAdapter);
        $authAdapter
            ->setTableName('view_users')
            ->setIdentityColumn('username')
            ->setCredentialColumn('password')
            ->setCredentialTreatment('MD5(?)');
        ;
        $authService = new AuthenticationService();
        $authService->setAdapter($authAdapter);
        $this->authService = $authService;
    }
    return $this->authService;
}

I have this in the service manager, but how do I modify it so $myParam can to passed when it is retrieved?

public function getServiceConfig() {
    return array(
        'factories' => array(
            'AuthService' => function($sm) {
                $dbAdapter = $this->getServiceLocator()->get($myParam);
                $authAdapter = new AuthAdapter($dbAdapter);
                $authAdapter
                    ->setTableName('view_users')
                    ->setIdentityColumn('username')
                    ->setCredentialColumn('password')
                    ->setCredentialTreatment('MD5(?)');
                ;
                $authService = new AuthenticationService();
                $authService->setAdapter($authAdapter);

                return $authService;
            }
        )
    );
}

The problem is that I want to be able to pass the factory the $db param when retrieving it from the service manager.

To be clear this question isn't specifically about how to authenticate to multiple DBs because this already works fine for me I just want to move my function into the service manager.

edit: crisp answered my actual question, but I found my real issue was a misunderstanding with how to use the Authentication class.

Long story short, I have a login controller that prompts for user creds then checks the user's access against all DBs and stores this info in Zend\Authentication\Storage\Session. Then from various other modules and can just call read() on Session and retrieve authorization info for the user.
