php - Symfony 4 - Autowiring 不工作

Question

我有一个将值写入特定实体的表单，我试图通过 Controller 中的函数编辑信息，非常简单。

银行 Controller .php

<?php

namespace App\Controller;

use App\Entity\Banco;
use App\Form\BancoType;
use App\Repository\BancoRepository;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Component\Form\FormFactoryInterface;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\HttpFoundation\Session\Flash\FlashBagInterface;
use Symfony\Component\HttpFoundation\Session\SessionInterface;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\Routing\RouterInterface;
use Symfony\Component\Security\Core\Authorization\AuthorizationCheckerInterface;
use Symfony\Component\HttpKernel\Exception\UnauthorizedHttpException;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Security;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;

class BancoController{

    private $twig;

    private $bancoRepository;

    private $formFactory;

    private $entityManager;

    private $router;

    private $flashBag;

    private $authorizationChecker;

    public function __construct(
        \Twig_Environment $twig, 
        BancoRepository $bancoRepository, 
        FormFactoryInterface $formFactory, 
        EntityManagerInterface $entityManager, 
        RouterInterface $router,
        FlashBagInterface $flashBag,
        AuthorizationCheckerInterface $authorizationChecker
    ){
        $this->twig = $twig;
        $this->bancoRepository = $bancoRepository;
        $this->formFactory = $formFactory;
        $this->entityManager = $entityManager;
        $this->router = $router;
        $this->flashBag = $flashBag;
        $this->authorizationChecker = $authorizationChecker;
    }

    /**
    * @Route("/cadastro/bancos", name="cadastro_banco")
    */
    public function index(TokenStorageInterface $tokenStorage){

        $usuario = $tokenStorage->getToken()->getUser();

        $html = $this->twig->render('bancos/index.html.twig', [
            'bancos' => $this->bancoRepository->findBy(array('usuario' => $usuario))
        ]);

        return new Response($html);
    }

    /**
    * @Route("/banco/{id}", name="editar")
    */
    public function editarBanco(Banco $banco, Request $request) {

        $form = $this->formFactory->create(
            BancoType::class,
            $banco
        );
        $form->handleRequest($request);

        if ($form->isSubmitted() && $form->isValid()){
            $this->entityManager->flush();

            return new RedirectResponse($this->router->generate('cadastro_banco'));
        }

        return new Response(
            $this->twig->render(
                'bancos/cadastro.html.twig',
                ['form' => $form->createView()]
            ));
    }

    /**
    * @Route("/cadastro/cadastrar-banco", name="cadastro_banco-nova")
    */
    public function cadastrar(Request $request, TokenStorageInterface $tokenStorage){

        $usuario = $tokenStorage->getToken()->getUser();

        $banco = new Banco();
        $banco->setUsuario($usuario);

        $form = $this->formFactory->create(BancoType::class, $banco);
        $form->handleRequest($request);

        if ($form->isSubmitted() && $form->isValid()){
            $this->entityManager->persist($banco);
            $this->entityManager->flush();

            return new RedirectResponse($this->router->generate('cadastro_banco'));
        }

        return new Response(
            $this->twig->render(
                'bancos/cadastro.html.twig',
                ['form' => $form->createView()]
        )
        );
    }
}

问题是，当我访问/banco/{id} 时，出现错误:

"Cannot autowire argument $banco of "App\Controller\BancoController::editarBanco()": it references class "App\Entity\Banco" but no such service exists."

我的 service.yaml 都是默认的，所以我想它应该会自动运行。 实体未显示在 bin/console debug:container 中。

如果我像这样在 services.yaml 中手动声明实体

App\Entity\Banco:
    autowire: true
    autoconfigure: true
    public: false

它可以工作，但现在当我访问/banco/{id} 时，表单变成空的，没有数据库中存在的信息，如果我输入一些内容并提交，数据库中没有任何变化。

如果我转到调试工具栏并检查查询，它似乎是在查询登录用户的 ID，而不是实体“Banco”的 ID。

顺便说一句，这个实体表有一个 FK user_id。也许这就是问题所在？ 我迷路了，所以我需要一点帮助。我是 PHP/Symfony 的新手。 谢谢

嗯，由于某些未知原因 sensio/framework-extra-bundle 没有完全安装。

我刚刚运行了 composer require annotations，现在一切正常。

该死，浪费了 2 天的时间试图解决这个问题..

谢谢大家!
