php - Symfony 3.4: Correctly configured service is not found

Question

I have an service class with the class name NewsService.

The service is configured as follows:

services:
    portal.news:
        class: xxx\NewsBundle\Service\NewsService
        arguments: ["@doctrine.orm.entity_manager"]

I use Phpstorm with symfony plugin - The plugin finds the service, but Symfony itself does not.

I get the following error message:

An exception has been thrown during the rendering of a template ("You have requested a non-existent service "portal.news".").

How I use the service:

{{ render(controller('xxBundle:Widget:renderNews', {'slice_length': 250})) }}
in the Controller xxBundle:Widget:renderNews: $articles = $this->get('portal.news')->getNewestArticles($count);
- cache is cleared
- I checked everything (wrong service configuration, bundle is loaded, syntax is ok, ...)

你可能忘了设置public: true你的服务，因为从 3.4 开始，所有 Symfony 服务默认都是私有的。

此外，您应该避免$this->get()使用函数，而是更喜欢直接从控制器参数中获取服务

<?php 
use xxx\NewsBundle\Service\NewsService
class MyController {
    public function myAction(NewsService $service)  {}
}
