    $builder->setMethod('get');
    $builder->add('username', 'text'); // add error to this field when username dont exist
    $builder->add('token', 'text') // add error on this field when token dont match with current token
        // transformer should set token to null
        ->addModelTransformer(new CallbackTransformer(
            function ($original) {
                return $original;
            },
            function ($submitted) {
                return null;
            }
        ));
    $builder->add('submit', 'submit');

// src/AppBundle/Entity/User.php
namespace AppBundle\Entity;

use Symfony\Component\Validator\Constraints as Assert;

class User
{
    /**
     * @Assert\NotBlank(message="Name is empty")
     */
    protected $name;
}

我不确定您在检查token的位置。不要忘记在$form->isValid()

之后添加$form->handleReqest($reqest)

通过输入表单加载实体并将未找到的错误消息添加到特定字段
