问题描述

以下是代码和配置:

Here is the code and configs:

code> services.yml 在我的包

<?phpnamespace Test\CommonBundle\Services;use Doctrine\ORM\EntityManager;class UserService { /** * * @var EntityManager */ protected $em; public function __constructor(EntityManager $entityManager) { var_dump($entityManager); exit(); // I've never saw it happen, looks like constructor never called $this->em = $entityManager; } public function getUser($userId){ var_dump($this->em ); // outputs null }}

Here is services.yml in my bundle

我在我的应用程序中将 config.yml 中导入了.yml

services: test.common.userservice: class: Test\CommonBundle\Services\UserService arguments: entityManager: "@doctrine.orm.entity_manager"

p>

I've imported that .yml in config.yml in my app like that

imports:
    # a few lines skipped, not relevant here, i think
    - { resource: "@TestCommonBundle/Resources/config/services.yml" }

当我在控制器中调用服务器

And when I call service in controller

    $userservice = $this->get('test.common.userservice');
    $userservice->getUser(123);

我得到一个对象(非空),但 $ this-> UserService中的em 为null,正如我已经提到的,UserService中的构造函数从未被调用过

I get an object (not null), but $this->em in UserService is null, and as I already mentioned, constructor on UserService has never been called

还有一件事,Controller和UserService不同的捆绑(我真的需要保持项目的组织),但仍然:其他工作正常,甚至可以调用

One more thing, Controller and UserService are in different bundles (I really need that to keep project organized), but still: everyting else works fine, I can even call

$this->get('doctrine.orm.entity_manager')

获取UserService并获取有效(不为null)EntityManager对象。

in same controller that I use to get UserService and get valid (not null) EntityManager object.

看起来我缺少配置或UserService和Doctrine配置之间的一些链接。

Look like that I'm missing piece of configuration or some link between UserService and Doctrine config.

推荐答案

您的类的构造方法应该称为 __ construct(),而不是$ code> __ constructor():

Your class's constructor method should be called __construct(), not __constructor():

public function __construct(EntityManager $entityManager)
{
    $this->em = $entityManager;
}
