How to configure zf2 and doctrine2 ?

Step-1 : install zf2 developer tool 

php composer.pharrequire zendframework/zend-developer-tools:dev-master

Step-2: add in application config/application.config.php

'modules' => array(
        'ZendDeveloperTools',
        'DoctrineModule',
        'DoctrineORMModule',
        'Application',
    ),

Step-3: Create your entity module/Application/src/Application/Entity/User

namespace Application\Entity;
use Doctrine\ORM\Mapping as ORM;
/** @ORM\Entity */
class User {
    /**
    * @ORM\Id
    * @ORM\GeneratedValue(strategy="AUTO")
    * @ORM\Column(type="integer")
    */
    protected $id;
    /** @ORM\Column(type="string") */
    protected $fullName;
    // getters/setters
}

Step-4: do mapping in module/Application/config/module.config.php

'doctrine' => array(
  'driver' => array(
    'application_entities' => array(
      'class' =>'Doctrine\ORM\Mapping\Driver\AnnotationDriver',
      'cache' => 'array',
      'paths' => array(__DIR__ . '/../src/Application/Entity')
    ),

    'orm_default' => array(
      'drivers' => array(
        'Application\Entity' => 'application_entities'
      )
))),

Step-5: configure connection config/autoload/doctrine.local.php

return array(
  'doctrine' => array(
    'connection' => array(
      'orm_default' => array(
        'driverClass' =>'Doctrine\DBAL\Driver\PDOMySql\Driver',
        'params' => array(
          'host'     => 'localhost',
          'port'     => '3306',
          'user'     => 'username',
          'password' => 'password',
          'dbname'   => 'database',
)))));

Step-6 , check you database create table or run doctrine command

php composer.pharrequire zendframework/zend-developer-tools:dev-master

Step-7 : test it .

module/Application/src/Application/Controller/IndexController.php

public function indexAction() {
    $objectManager = $this
        ->getServiceLocator()
        ->get('Doctrine\ORM\EntityManager');

    $user = new \Application\Entity\User();
    $user->setFullName('Marco Pivetta');

    $objectManager->persist($user);
    $objectManager->flush();

    die(var_dump($user->getId())); // yes, I'm lazy
}
