namespace Firewall;

        'factories' => array(

                $dbAdapter = $sm->get('db-adapter');
                $table = new UserTable($dbAdapter);
                return $table;

                    $config = $sm->get('config');
                    $config = $config['db'];
                    $dbAdapter = new DbAdapter($config);
                    return $dbAdapter;
                },

/module/Application/config/autoload/global.php

return array(
    'db' => array(
        'driver' => 'Pdo',
        'dsn' => 'mysql:dbname=firewall;hostname=localhost',
        'username' => 'aaaaaa',
        'password' => 'aaaaaa',

            PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
        ),
    ),
);

my call in a controller:

if (!$this->userTable) {
            $sm = $this->getServiceLocator();
            $this->userTable = $sm->get('user-table');
        }
        return $this->userTable;

Thanks you very very much for your helping... I'm blocked.. :/

Answer 1

尝试使用：

public function getServiceConfig() //instead of getServiceConfiguration()

Answer 2

I think the problem is you trying to use service to to configure your Db environment in global.php but the way you wrote your code is not using service manager in global.php.

Try to change your global to this since you are using service manager and factory db.

 return array(
'service_manager' => array(
    'factories' => array(
        'Zend\Db\Adapter\Adapter' => 'Zend\Db\Adapter\AdapterServiceFactory',
    ),
),
    'db' => array('driver' => 'Pdo',
    'dsn' => 'mysql:dbname=firewall;host=localhost;charset=utf8',
    'user' => 'root', 'pass' => 'aaaa' ),
     'driver_options' => array(
        PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''       
),

);
