我使用的是 Micro Kernel，并尝试配置 Doctrine ORM。

应用程序/配置/config.yml

framework:
    secret: S0ME_SECRET
    templating:
        engines: ['twig']
    profiler: { only_exceptions: false }

doctrine:
    dbal:
        driver:   pdo_mysql
        host:     127.0.0.1
        dbname:   symfony-micro
        user:     root
        password: ''

    orm:

应用程序/AppKernel.php

use Symfony\Bundle\FrameworkBundle\Kernel\MicroKernelTrait;
use Symfony\Component\Config\Loader\LoaderInterface;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\HttpKernel\Kernel;
use Symfony\Component\Routing\RouteCollectionBuilder;
use Doctrine\Common\Annotations\AnnotationRegistry;


$loader = require __DIR__.'/../vendor/autoload.php';

AnnotationRegistry::registerLoader(array($loader, 'loadClass'));

class AppKernel extends Kernel
{
    use MicroKernelTrait;

    public function registerBundles()
    {
        $bundles = array(
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
            new Symfony\Bundle\TwigBundle\TwigBundle(),
            new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
            new Doctrine\Bundle\DoctrineBundle\DoctrineBundle()
        );

        if ($this->getEnvironment() == 'dev') {
            $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
        }

        return $bundles;
    }

    protected function configureContainer(ContainerBuilder $c, LoaderInterface $loader)
    {
        $loader->load(__DIR__.'/config/config.yml');

        if (isset($this->bundles['WebProfilerBundle'])) {
            $c->loadFromExtension('web_profiler', array(
                'toolbar' => true,
                'intercept_redirects' => false,
            ));
        }
    }

    protected function configureRoutes(RouteCollectionBuilder $routes)
    {
        if (isset($this->bundles['WebProfilerBundle'])) {
            $routes->import('@WebProfilerBundle/Resources/config/routing/wdt.xml', '/_wdt');
            $routes->import('@WebProfilerBundle/Resources/config/routing/profiler.xml', '/_profiler');
        }

        $routes->import(__DIR__.'/../src/App/Controller/', '/', 'annotation');
    }

    public function getCacheDir()
    {
        return __DIR__.'/../var/cache/'.$this->getEnvironment();
    }

    public function getLogDir()
    {
        return __DIR__.'/../var/logs';
    }
}

src/App/ControllerMicroController.php

namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;

use App\Entity\Article;

class MicroController extends Controller
{
    /**
     * @Route("/test/{limit}")
     */
    public function testAction($limit)
    {
        $article = $this->getDoctrine()
        ->getRepository(Article::class)
        ->find(1);

        echo '<pre>';
        print_r($articles);
        die;
    }
}

src/App/Entity/Article.php

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Article
 *
 * @ORM\Table(name="article")
 * @ORM\Entity(repositoryClass="App\Repository\ArticleRepository")
 */
class Article
{
    /**
     * @var int
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @var string
     *
     * @ORM\Column(name="content", type="text")
     */
    private $content;
...

当我尝试从数据库中获取某些内容时，我得到：

班上'App\Entity\Article' was not found in the chain configured namespaces

我认为问题出在 ORM 配置中。任何人都可以帮忙吗？

配置 Doctrine ORM 的推荐方法MicroKernelTrait已经暴露在Symfony 存储库中的 Doctrine 配方中：

doctrine:
    # ...
    orm:
        auto_generate_proxy_classes: '%kernel.debug%'
        naming_strategy: doctrine.orm.naming_strategy.underscore
        auto_mapping: true
        mappings:
            App:
                is_bundle: false
                type: annotation
                dir: '%kernel.project_dir%/src/Entity'
                prefix: 'App\Entity\'
                alias: App

此配置应涵盖您的无捆绑结构。
