对此问题的解答已经解决： Symfony 4 and Doctrine, how to generate repository automatically after mapping?

我在从MySQL表获取数据时遇到问题，

这是我的控制器：

namespace App\Controller\Admin;

use Symfony\Component\Routing\Annotation\Route;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\TextareaType;
use Symfony\Component\Form\Extension\Core\Type\ChoiceType;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
use App\Entity\EmailComponents;

class MigrationController extends AbstractController
{

/**
 * @Route("/migration", name="migration_script")
 */
public function index(Request $request)
{
    $entityManager = $this -> getDoctrine() -> getManager();

    $email = new EmailComponents();

    $form = $this->createFormBuilder($email)
        ->add('language', ChoiceType::class, [
            'choices' => [
                'Anglais' => 'en',
                'Français' => 'fr',
                'Allemend' => 'de',
                'Néerlandais' => 'nl',
            ],
            ])
        ->add('subject', TextType::class)
        ->add('body', TextareaType::class)
        ->add('save', SubmitType::class, ['label' => 'Crée Email'])
        ->getForm();

    $form->handleRequest($request);

    if ($form->isSubmitted() && $form->isValid()) {
        $email = $form->getData();
        $entityManager -> persist($email);
        $entityManager -> flush();

        $this->addFlash('success', 'Email a été crée avec succès');

        return $this -> redirectToRoute('migration_script');
    }


    $search = $entityManager -> getRepository(EmailComponents::class) -> findAll();

    return $this->render('admin/migration/index.html.twig', array(
        'form' => $form -> createView()
    ));
}

这是EmailComponents.php文件：

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;


/**
 * @ORM\Entity(repositoryClass="App\Repository\EmailComponentRepository")
 */
class EmailComponents
{
/**
 * @ORM\Id
 * @ORM\GeneratedValue
 * @ORM\Column(type="integer")
 */
private $id;

/**
 * @ORM\Column(type="string", length=2)
 */
private $language;

/**
 * @ORM\Column(type="string", length=250)
 */
private $subject;

/**
 * @ORM\Column(type="string", length=5000)
 */
private $body;


public function getId()
{
    return $this->id;
}

public function setId($id)
{
    $this->id = $id;
}

public function getLanguage()
{
    return $this->language;
}

public function setLanguage($language)
{
    $this->language = $language;
}

public function getSubject()
{
    return $this->subject;
}

public function setSubject($subject)
{
    $this->subject = $subject;
}

public function getBody()
{
    return $this->body;
}

public function setBody($body)
{
    $this->body = $body;
}
}

问题是，每次我运行页面时，都会收到此错误消息：

“ App \ Entity \ EmailComponents”实体的repositoryClass设置为 “ App \ Repository \ EmailComponentRepository”，但这不是有效的类。检查您的班级命名。如果这是服务编号，确保此服务存在并标记了 “ doctrine.repository_service”。

错误来自此部分：

$search = $entityManager -> getRepository(EmailComponents::class) -> findAll();

Answer 1

我找到了解决方法：

我用过：

 php bin\console make:entity --regenerate

生成缺少的类。

Answer 2

我遇到了同样的问题，对我来说，这是因为我的entityRepository文件不是.php文件（但其中包含了php代码），我感到很愚蠢，因为颜色正确，phpstorm并没有帮助我。

我用Sinf说了php bin\console make:entity --regenerate解决了这个问题谢谢！
