DbTableAuthAdapter is deprecated how to solve it?

[zhushaolei]

• I was not able to find a solution to the DbTableAuthAdapte deprecated:
  in follwoing snippet:

public function getServiceConfig()
    {
        return array(
            'abstract_factories' => array(),
            'aliases' => array(),
            'factories' => array(
                // SERVICES
                'AuthService' => function($sm) {
                $dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
                $dbTableAuthAdapter = new DbTableAuthAdapter($dbAdapter, 'user','email','password', 'MD5(?)');
                
                $authService = new AuthenticationService();
                $authService->setAdapter($dbTableAuthAdapter);
                return $authService;
                },

Provide a narrative description of what you are trying to accomplish.
I wish to get a correct solution ( a snippet code) against to DbTableAuthAdapter to fix my login functionality and continue to study and practise on the book" Zend Framework2.0 by example"

The Zend\Authentication\Adapter\DbTable is not a part of the zend-db component. It belongs to zend-authentication.
Please look at the documentation of zend-authentication. There you will find the notification of the deprecation and the also how you can fix the problem: https://docs.zendframework.com/zend-authentication/adapter/dbtable/intro/#zendauthenticationadapterdbtable-class-is-deprecated
