未找到控制器：服务“；AppBundle/Controller/TestController.php“；不存在

我发现错误

找不到控制器：服务“AppBundle/Controller/TestController.php”不存在

但我不知道如何调试它。有人能帮帮我吗！？ 可能是路由错误还是其他原因造成的！？ 我只是想澄清一下，我使用的是Symfony 3.4

下面是TestController.php代码的摘录

<?php

namespace AppBundle\Controller;

use AppBundle\Entity\Task;
use AppBundle\Form\TaskType;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;

/**
 * @Route("test/form-test")
 */
class TestController extends Controller
{
    /**
     * @Route("/", name="test")
     */
    public function newAction(Request $request)
    {
        // creates a task and gives it some dummy data for this example
        $task = new Task();
        $task->setTask('Write a blog post');
        $task->setDueDate(new \DateTime('tomorrow'));

        $form = $this->get('form.factory')->createNamed('addTask', TaskType::class, $task);

        $form->handleRequest($request);

        $validator = $this->get('validator');
        $errors = $validator->validate($form);
        if (count($editErrors) > 0) {
            $errorsString = (string)$editErrors;

            return new Response($errorsString);
        }
        echo('------------------------------------------------------------------------' . $form->isSubmitted() . ' && ' . $form->isValid());
        if ($form->isSubmitted() && $form->isValid()) {
            // $form->getData() holds the submitted values
            // but, the original `$task` variable has also been updated
            $task = $form->getData();

            // ... perform some action, such as saving the task to the database
            // for example, if Task is a Doctrine entity, save it!
            // $entityManager = $this->getDoctrine()->getManager();
            // $entityManager->persist($task);
            // $entityManager->flush();
            return new Response('<h1>-----------------------------------------------------------------------------------OK</h1>');
        }

        return $this->render('default/index.html.twig', [
            'form' => $form->createView(),
            'errors' => $errors,
        ]);
    }
}

你能给这个问题添加一些相关的代码吗，是什么添加的代码触发了错误？TestController存在吗？你试着做什么来调试自己？已经完成了。你的意思是你解决了它？还没有。。。但我在问题中添加了代码。我就是这么做的：我明白了！因此，当您尝试访问“/test/formtest”时会发生错误？此控制器是否放置在控制器目录中？php-bin/console-debug:container的输出是什么，您能在那里找到控制器服务吗？
