在 symfony2.7 中使用工厂创建服务

Question

symfony2.7如何使用工厂创建服务？

#service.yml
#in symfony 2.6
my.repository.photo:
    class: My\AppBundle\Repository\PhotoRepository
    factory_method: getRepository
    factory_service: doctrine
    arguments: [My\AppBundle\Entity\Photo]

#I have some errors like this
Deprecated: Symfony\Component\DependencyInjection\Definition::setFactoryMethod(getRepository) is deprecated since version 2.6 and will be removed in 3.0. Use Definition::setFactory() instead. in /my/vendor/symfony/symfony/src/Symfony/Component/DependencyInjection/Definition.php on line 137

我现在如何使用 "setFactory" 方法？文档：http://symfony.com/doc/master/components/dependency_injection/factories.html

谢谢！

我觉得相关文档写的很清楚。试试这个配置：

my.repository.photo:
    class: My\AppBundle\Repository\PhotoRepository
    factory: ["@doctrine", getRepository]
    arguments: [My\AppBundle\Entity\Photo]

已弃用的错误是为即将推出的 Symfony 3.0 做准备。一些功能（如 factory_service|factory_method）将被删除。这是一个线程，如果您真的不需要它，您可以在其中找到解决方案。
