如何从实体数据行获取多个数据

 public function findByUser1Id($userId)
       {
           $connections = $this->_em
               ->getRepository('AppBundle:ConnectionsList')
               ->findBy(array('user1Id' => $userId));

           foreach($connections as $con)
           {
               $user = $this->_em
                   ->getRepository('AppBundle\Entity\User')
                   ->findOneBy(array('id' => $con->getUser2Id()));

               var_dump($user->getFirstname());
               var_dump($user->getLastname());
               var_dump($user->getEmail());
               var_dump($user->getId());
               die;
           }
       }

我需要一些方法来在一行中获取数据：

$user->get(array('firstname', 'lastname', 'email' ...))

我找到了解决方案，但无法在一行中获取所有数据

代码在这里：
