ZF3如何处理AbstractContoller中的getServiceLocator（） - > get（'translator'）

Question

I have an abstract controller in my app (ZF3) which extends all my module controllers.

I'm calling here my base translator and apply the translator also per module but as getServiceLocator() is removed from ZF3 I'm wonder what I can do to create a $this->translator in that extended controller.

This what I used in ZF2:

$this->translator = $this->getServiceLocator()->get('translator');

I have found these docs but this is seems another purpose to me.

Answer 1

There are different ways to overcome this problem.

First solution that comes in mind, which is more of a quick fix than anything else, is to inject the service locator in every controller. In order to do that, you'll need to inject it through the constructor and change your factory for controllers (factories if many of them).

As you do that, yoou can only inject the translator rather than the container (service manager).

Initializers are indeed a way to go, but they might be removed later on. I would probably rather use a delegator. This way, you do not have to inject through the constructor, but you'll need to inject through a setter, meaning you introduce temporal coupling...
