我目前正在做一个项目，目标是用Symfony从一个繁重的Java应用程序转移到一个Web应用程序。
目标是从现有数据库开始，而根本不修改它。
在这个数据库中，密码是用md5散列的，经过几个星期的麻烦，我无法改变symfony的散列系统来使用md5。
我已经做了几个测试，对于这一行，密码被很好地散列了：哈希（"md5"，$密码）;
只是，我希望散列可以自动完成，就像在基本的symfony中一样。所以我按照symfony文档，尝试在secutiry.yaml中添加以下代码行：密码哈希器（_H）：应用程序哈希器：ID："应用程序\安全\哈希程序\自定义安全哈希程序"
因此，指向按如下方式填写的CustomVerySecureHasher文件：

class CustomVerySecureHasher implements PasswordHasherInterface
{
    public function hash(string $plainPassword): string
    {
        // Check if the MD5 hash algorithm is supported
        if (!in_array('md5', hash_algos(), true)) {
            throw new Exception('MD5 is not supported by this system.');
        }

        // Hash the password using the MD5 algorithm
        return md5($plainPassword);
    }

    public function verify(string $hashedPassword, string $plainPassword): bool
    {
        // Compare the hashed password with the MD5 hashed plaintext password
        return $hashedPassword === md5($plainPassword);
    }

    public function needsRehash(string $hashedPassword): bool
    {
        // There is no need to rehash with MD5, as it is considered insecure
        return false;
    }
}

不幸的是，这似乎不起作用。我尝试了多种解决方案，但都不起作用。
下面是我的AppCustomAuthenticator类的外观（由php bin/console make：auth命令生成）：

class AppCustomAuthenticator extends AbstractLoginFormAuthenticator
{
    use TargetPathTrait;

    public const LOGIN_ROUTE = 'app_login';

    public function __construct(private UrlGeneratorInterface $urlGenerator)
    {
    }

    public function authenticate(Request $request): Passport
    {
        $email = $request->request->get('login', '');

        $request->getSession()->set(Security::LAST_USERNAME, $email);

//        $password = $request->request->get('password', '');
//        $test = hash('md5', $password);
//        dd($test);

        return new Passport(
            new UserBadge($email),
            new PasswordCredentials($request->request->get('password', '')),
            [
                new CsrfTokenBadge('authenticate', $request->request->get('_csrf_token')),
            ]
        );
    }

    public function onAuthenticationSuccess(Request $request, TokenInterface $token, string $firewallName): ?Response
    {
        if ($targetPath = $this->getTargetPath($request->getSession(), $firewallName)) {
            return new RedirectResponse($targetPath);
        }

        // For example:
        // return new RedirectResponse($this->urlGenerator->generate('some_route'));
        throw new \Exception('TODO: provide a valid redirect inside '.__FILE__);
    }

    protected function getLoginUrl(Request $request): string
    {
        return $this->urlGenerator->generate(self::LOGIN_ROUTE);
    }
}

我已经测试了几次，我从我的表单中得到了我的登录名和密码，没有任何问题。确实，哈希阶段是问题所在。
下面是我在安全控制器中的登录方法：

#[Route(path: '/', name: 'app_login')]
public function login(AuthenticationUtils $authenticationUtils): Response
{
    // if ($this->getUser()) {
    //     return $this->redirectToRoute('target_path');
    // }

    // get the login error if there is one
    $error = $authenticationUtils->getLastAuthenticationError();
    // last username entered by the user
    $lastUsername = $authenticationUtils->getLastUsername();
//        if ($lastUsername) {
//            dd($lastUsername);
//        }

    return $this->render('/security/login.html.twig', ['login' => $lastUsername, 'error' => $error]);
}

[编辑]：以下是我的security. yaml文件的内容：

security:
    password_hashers:
        App\Entity\Useraccount:
            id: 'App\Security\Hasher\CustomVerySecureHasher'
    providers:
        users_in_memory: { memory: null }
    firewalls:
        dev:
            pattern: ^/(_(profiler|wdt)|css|images|js)/
            security: false
        main:
            lazy: true
            provider: users_in_memory
            custom_authenticator: App\Security\AppCustomAuthenticator
access_control:

when@test:
    security:
        password_hashers:
            Symfony\Component\Security\Core\User\PasswordAuthenticatedUserInterface:
                algorithm: auto
                cost: 4 # Lowest possible value for bcrypt
                time_cost: 3 # Lowest possible value for argon
                memory_cost: 10 # Lowest possible value for argon

有人有什么想法吗？
我用的是php 8.1和symfony 6.2
