Question

您好，我使用了Symfony2文档中两个不同数据库连接的示例：Symfony2 multiple connections documentation 因此，Symfony找不到客户实体经理。（参数定义正确）

doctrine:
dbal:
    default_connection: default
    connections:
        default:
            driver:   "%database_driver%"
            host:     "%database_host%"
            port:     "%database_port%"
            dbname:   "%database_name%"
            user:     "%database_user%"
            password: "%database_password%"
            charset:  UTF8
        customer:
            driver:   "%database_driver%"
            host:     "%database_host2%"
            port:     "%database_port2%"
            dbname:   "%database_name2%"
            user:     "%database_user2%"
            password: "%database_password2%"
            charset:  UTF8

orm:
    default_entity_manager: default
    entity_managers:
        default:
            connection: default
            mappings:
                AppBundle:  ~
        customer:
            connection: customer
            mappings:
                AppBundle: ~

控制器如下所示：

class DefaultController extends Controller
{
/**
 * @Route("/", name="homepage")
 */
public function indexAction(Request $request)
{
    $em = $this->get('doctrine')->getManager();
    $em = $this->get('doctrine')->getManager('default');
    $em = $this->get('doctrine.orm.default_entity_manager');

    // Both of these return the "customer" entity manager
    $customerEm = $this->get('doctrine')->getManager('customer');
    $customerEm = $this->get('doctrine.orm.customer_entity_manager');
    return $this->render('default/index.html.twig', array(
        'base_dir' => realpath($this->container->getParameter('kernel.root_dir').'/..'),
    ));
}

我应该获得costumer实体管理器，但是Symfony会在消息中引发无效的参数异常。

[2015-10-19 23:19:18] request.CRITICAL: Uncaught PHP Exception 
InvalidArgumentException: "Doctrine ORM Manager named "customer" does 
not exist." at /srv/www/htdocs/symfony/my_project_name/app/cache

(InvalidArgumentException(code: 0): Doctrine ORM Manager named 
\"customer\" does not exist. at /srv/www/htdocs/symfony/my_project_name

我使用php app / console cache清理缓存：清除但这没有帮助。

Answer 1

Artamiel在评论中得到了正确答案：

Symfony2 Doctrine ORM Manager named "customer" does not exist

cache：clear默认清除dev环境，但查看错误日志，就会在prod环境中收到错误。要清除生产环境中的缓存，请添加-e prod标志，如此缓存：clear -e prod并刷新页面。

Answer 2

首先，我认为，控制器中的实体经理的一个声明就足够了：

/ *** /   
public function indexAction(Request $request)
{
    $em = $this->get('doctrine')->getManager('default');

    $customerEm = $this->get('doctrine')->getManager('customer');

    / *** /
}

其次，您确定可以在映射配置中声明相同的包（在这种情况下为AppBundle: ~）吗？

Symfony2 Doctrine ORM经理名为＆＃34;客户＆＃34;不存在
