Question

我在Symfony非常新。我在symfony 2.3 LTS开始了我的第一个项目。这时我已经在不同的包中创建了许多控制器。我的问题涉及正确的程序。我在我的控制器中使用不同的服务，例如翻译工具，工厂＆＃39;会话＆＃39;路由器＆＃39;，＆＃39; entitymanager＆＃39;，＆＃39;模板＆＃39;。

我在我的＆＃34; service.yml＆＃34;中创建基础服务

myapp.controller.base:
    class: "%myapp.controller.base.class%"
    arguments: ["@doctrine.orm.entity_manager", , "@templating", "@session", "@translator", "@router", "@form.factory"]

并在我的控制器中注入基本服务，该控制器也是一项服务。

myapp.controller.locales:
    class: "%myapp.controller.locales.class%"
    arguments: ["@myapp.controller.base"]

我的基本服务看起来像这样。

namespace MyApp\<BundleName>\Controller;
use Symfony\Bundle\FrameworkBundle\Templating\EngineInterface;
use Symfony\Component\HttpFoundation\Session\Session;

class BaseController
{
protected $formErrorService;
protected $entityManager;
protected $templating;
protected $session;
protected $translator;
protected $router;
protected $formFactory;

public function __construct($entityManager, EngineInterface $templating, Session $session, $translator, $router, $formFactory)
{
    $this->setEntityManager($entityManager);
    $this->setTemplating($templating);
    $this->setSession($session);
    $this->setTranslator($translator);
    $this->setRouter($router);
    $this->setFormFactory($formFactory);
}

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

public function getEntityManager()
{
    return $this->entityManager;
}

public function setTemplating（$ templating） { $ this-＆gt; templating = $ templating; }

public function getTemplating()
{
    return $this->templating;
}

public function setSession($session)
{
    $this->session = $session;
}

public function getSession()
{
    return $this->session;
}

public function setTranslator($translator)
{
    $this->translator = $translator;
}

public function getTranslator()
{
    return $this->translator;
}

public function setRouter($router)
{
    $this->router = $router;
}

public function getRouter()
{
    return $this->router;
}

public function setFormFactory($formFactory)
{
    $this->formFactory = $formFactory;
}

public function getFormFactory()
{
    return $this->formFactory;
}
}

我在我的语言环境控制器中调用这个

namespace MyApp\<Bundlename>\Controller;

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\HttpFoundation\Session\Session;

class LocalesController extends BaseController
{

protected $baseService;

public function __construct($baseService)
{
    $this->baseService = $baseService;
}

public function indexAction(Request $request)
{

$locales=$this->baseService->getEntityManager()->getRepository('<reponame>')->findAll();
    return  $this->baseService->getTemplating()->renderResponse('<templatename>', array('locales' => $locales));
}

这是正确的程序吗？我应该在我需要这项服务的ervery控制器中使用这个程序吗？

我希望我得到有用的提示，非常感谢

将一个控制器注入另一个控制器的方法不正确。您应该使用parent作为您的子控制器。

示例：

myapp.controller.base:
    class: "%myapp.controller.base.class%"
    arguments: ["@doctrine.orm.entity_manager", , "@templating", "@session", "@translator", "@router", "@form.factory"]

myapp.controller.locales:
    class: "%myapp.controller.locales.class%"
    parent: myapp.controller.base
