Configure multiple databases in zf2 with doctrine2 - doctrine-orm

Question

How can I configure (and use) multiple databases in Zend Framework 2 with doctrine 2 ? Currently I have this in my local.php:
return array(
'doctrine' => array(
'connection' => array(
// default connection name
'orm_default' => array(
'driverClass' => 'Doctrine\DBAL\Driver\PDOMySql\Driver',
'params' => array(
'host' => 'localhost',
'port' => '3306',
'user' => 'root',
'password' => '',
'dbname' => 'data1',
'charset' => 'utf8',
'driverOptions' => array(
1002=>'SET NAMES utf8'
)
)
)
)
),
);
But I do not see a way to add a second one.

Perhaps this example might show you the way, this is how I configured two databases in my application, but I'm not using Doctrine.
DBs configuration
return array(
'doctrine' => array(
'connection1' => array(
// default connection name
'orm_default' => array(
'driverClass' => 'Doctrine\DBAL\Driver\PDOMySql\Driver',
'params' => array(
'host' => 'localhost',
'port' => '3306',
'user' => 'root',
'password' => '',
'dbname' => 'data1',
'charset' => 'utf8',
'driverOptions' => array(1002 => 'SET NAMES utf8')
)
)
),
'connection2' => array(
// default connection name
'orm_default' => array(
'driverClass' => 'Doctrine\DBAL\Driver\PDOMySql\Driver',
'params' => array(
'host' => 'localhost',
'port' => '3306',
'user' => 'root',
'password' => '',
'dbname' => 'data2',
'charset' => 'utf8',
'driverOptions' => array(1002 => 'SET NAMES utf8')
)
)
)
),
);
Then you need to create a DbAdapterFactory that connect to DB connection1 and another factory to connect to DB connection2:
PS: Of course the names are just examples and you can use better ones.
class Adapter1Factory implements FactoryInterface
{
/**
* Create DbAdapter
*
* #param ServiceLocatorInterface $serviceLocator
* #return DbAdapter
*/
public function createService(ServiceLocatorInterface $serviceLocator)
{
$config = $serviceLocator->get('config');
$configDb1 = $config['connection1'];
$adapter = new \Zend\Db\Adapter\Adapter($configDb1);
return $adapter;
}
}
class Adapter2Factory implements FactoryInterface
{
/**
* Create DbAdapter
*
* #param ServiceLocatorInterface $serviceLocator
* #return DbAdapter
*/
public function createService(ServiceLocatorInterface $serviceLocator)
{
$config = $serviceLocator->get('config');
$configDb2 = $config['connection2'];
$adapter = new \Zend\Db\Adapter\Adapter($configDb2);
return $adapter;
}
}
Now just use the specific AdapterFactory when you want to connect to certain DB.
