    database_port_another: null
    database_name_another: another_database
    database_user_another: another_user
    database_password_another: another_password

doctrine:
    dbal:

        connections:
            default:

# doctrine.yml

doctrine:

        entity_managers:

// 在控制器或服务中获取实体管理器
$defaultEntityManager = $this->getDoctrine()->getManager('default');
$anotherEntityManager = $this->getDoctrine()->getManager('another');

// 使用实体管理器进行数据库操作
$defaultEntityManager->getRepository('AppBundle:Entity')->findAll();
$anotherEntityManager->getRepository('AnotherBundle:Entity')->findAll();
