在我的案例中,基于@Tomáš Votruba 的回答和这个问题,我提出了以下方法:
适配器方法
没有继承
创建一个通用适配器类:
namespace AppBundle\Services;
use Doctrine\ORM\EntityManagerInterface;
class RepositoryServiceAdapter
{
private $repository=null;
/**
* @param EntityManagerInterface the Doctrine entity Manager
* @param String $entityName The name of the entity that we will retrieve the repository
*/
public function __construct(EntityManagerInterface $entityManager,$entityName)
{
$this->repository=$entityManager->getRepository($entityName)
}
public function __call($name,$arguments)
{
if(empty($arrguments)){ //No arguments has been passed
$this->repository->$name();
} else {
//@todo: figure out how to pass the parameters
$this->repository->$name(...$argument);
}
}
}
然后为每个实体定义一个服务,例如在我的例子中定义一个(我使用php来定义symfony服务):
$container->register('ellakcy.db.contact_email',AppBundle\Services\Adapters\RepositoryServiceAdapter::class)
->serArguments([new Reference('doctrine'),AppBundle\Entity\ContactEmail::class]);
有继承
与上述步骤 1 相同
扩展RepositoryServiceAdapter
类例如:
namespace AppBundle\Service\Adapters;
use Doctrine\ORM\EntityManagerInterface;
use AppBundle\Entity\ContactEmail;
class ContactEmailRepositoryServiceAdapter extends RepositoryServiceAdapter
{
public function __construct(EntityManagerInterface $entityManager)
{
parent::__construct($entityManager,ContactEmail::class);
}
}
注册服务:
$container->register('ellakcy.db.contact_email',AppBundle\Services\Adapters\RepositoryServiceAdapter::class)
->serArguments([new Reference('doctrine')]);
如果您有一个很好的可测试方法来测试您的数据库行为,它也可以帮助您模拟,以防您想要对您的服务进行单元测试,而无需过多担心如何做到这一点。例如,假设我们有以下服务:
//Namespace definitions etc etc
class MyDummyService
{
public function __construct(RepositoryServiceAdapter $adapter)
{
//Do stuff
}
}
并且 RepositoryServiceAdapter 适应以下存储库:
//Namespace definitions etc etc
class SomeRepository extends \Doctrine\ORM\EntityRepository
{
public function search($params)
{
//Search Logic
}
}
测试
因此,您可以通过模拟非继承方法或继承方法来轻松模拟/硬编码/模拟search
定义的方法的行为。SomeRepository
RepositoryServiceAdapter
ContactEmailRepositoryServiceAdapter
工厂方法
或者,您可以定义以下工厂:
namespace AppBundle\ServiceFactories;
use Doctrine\ORM\EntityManagerInterface;
class RepositoryFactory
{
/**
* @param EntityManagerInterface $entityManager The doctrine entity Manager
* @param String $entityName The name of the entity
* @return Class
*/
public static function repositoryAsAService(EntityManagerInterface $entityManager,$entityName)
{
return $entityManager->getRepository($entityName);
}
}
然后通过执行以下操作切换到 php 服务注释:
将其放入文件./app/config/services.php
中(对于 symfony v3.4,.
假定您的 ptoject 的根目录)
use Symfony\Component\DependencyInjection\Definition;
use Symfony\Component\DependencyInjection\Reference;
$definition = new Definition();
$definition->setAutowired(true)->setAutoconfigured(true)->setPublic(false);
// $this is a reference to the current loader
$this->registerClasses($definition, 'AppBundle\\', '../../src/AppBundle/*', '../../src/AppBundle/{Entity,Repository,Tests,Interfaces,Services/Adapters/RepositoryServiceAdapter.php}');
$definition->addTag('controller.service_arguments');
$this->registerClasses($definition, 'AppBundle\\Controller\\', '../../src/AppBundle/Controller/*');
并且 cange ./app/config/config.yml
(.
假设您的 ptoject 的根)
imports:
- { resource: parameters.yml }
- { resource: security.yml }
#Replace services.yml to services.php
- { resource: services.php }
#Other Configuration
然后您可以按如下方式关闭服务(在我使用名为 的虚拟实体的示例中使用Item
):
$container->register(ItemRepository::class,ItemRepository::class)
->setFactory([new Reference(RepositoryFactory::class),'repositoryAsAService'])
->setArguments(['$entityManager'=>new Reference('doctrine.orm.entity_manager'),'$entityName'=>Item::class]);
同样作为一个通用技巧,切换到php
服务注释可以让您轻松完成上述更高级的服务配置。对于代码片段,请使用我使用该方法制作的特殊存储库。factory
