将我的项目从Symfony 3.4.0 BETA 2升级到3.4.0 BETA 4后，我在每个请求和每个cli命令中都出现以下错误：

[Doctrine\ORM\ORMException]
It's a requirement to specify a Metadata Driver and pass it to Doctrine\ORM\Configuration::setMetadataDriverImpl().

检查我发现的生成的缓存代码后，实例化EntityManager的代码与BETA 2中的代码完全不同。

这是来自BETA 2的代码：

<?php

use Symfony\Component\DependencyInjection\Argument\RewindableGenerator;

// This file has been auto-generated by the Symfony Dependency Injection Component for internal use.
// Returns the public 'doctrine.orm.default_entity_manager' shared service.

$a = ${($_ = isset($this->services['annotation_reader']) ? $this->services['annotation_reader'] : $this->load(__DIR__.'/getAnnotationReaderService.php')) && false ?: '_'};

$b = new \Doctrine\ORM\Mapping\Driver\AnnotationDriver($a, array(0 => 'D:\\jinya-gallery-cms\\src\\HelperBundle\\Entity', 1 => 'D:\\jinya-gallery-cms\\src\\DataBundle\\Entity'));

$c = new \Doctrine\Common\Persistence\Mapping\Driver\MappingDriverChain();
$c->addDriver($b, 'HelperBundle\\Entity');
$c->addDriver($b, 'DataBundle\\Entity');

return $instance;

        $e->setEntityListenerResolver(${($_ = isset($this->services['doctrine.orm.default_entity_listener_resolver']) ? $this->services['doctrine.orm.default_entity_listener_resolver'] : $this->services['doctrine.orm.default_entity_listener_resolver'] = new \Doctrine\Bundle\DoctrineBundle\Mapping\ContainerAwareEntityListenerResolver($this)) && false ?: '_'});

        ${($_ = isset($this->services['doctrine.orm.default_manager_configurator']) ? $this->services['doctrine.orm.default_manager_configurator'] : $this->services['doctrine.orm.default_manager_configurator'] = new \Doctrine\Bundle\DoctrineBundle\ManagerConfigurator(array(), array())) && false ?: '_'}->configure($instance);

        return $instance;
    }
}

结果是，在BETA 4中，在设置配置值之前创建EntityManager。有谁知道如何影响缓存生成以创建工作缓存？

答案 0 :(得分：1)

对我有用的解决方案：

  1. 使用composer require ocramius/proxy-manager
    2. 安装Lazy Services

  2. 对于每个侦听器，在lazy: true

    中设置其他参数tags 
    app.service_doctrine.foo_listerner:
class: AppBundle\Service\Doctrine\FooListener
...
tags:
    - { name: doctrine.orm.entity_listener, entity_manager: default, lazy: true }
