DataTables Omines捆绑包出现错误Symfony 4

我想知道如何使DataTables捆绑包工作，因为我一直无法使它工作

我执行了这个命令“composerrequireomines/datatables包”。 在此之后，我执行了“PHPBIN/console资产：安装”。 我还添加了依赖项

但是当我进入我的页面时，我有一个错误，您请求了一个不存在的服务“Omines\DataTablesBundle\DataTableFactory”

你能帮我吗

<?php

namespace App\Controller;

use App\Entity\User;
use App\Form\AdminUserFormType;
use App\Repository\UserRepository;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Component\HttpFoundation\Request;
use Omines\DataTablesBundle\Column\TextColumn;
use Symfony\Component\Routing\Annotation\Route;
use Omines\DataTablesBundle\Adapter\ArrayAdapter;
use Symfony\Component\HttpFoundation\JsonResponse;
use Omines\DataTablesBundle\Controller\DataTablesTrait;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;

class UsersController extends Controller
{

    use DataTablesTrait;

    /**
     * @Route("/admin/user/test", name="users_test")
     */
    public function usersTest(Request $request){
        $table = $this->createDataTable()
            ->add('firstName', TextColumn::class)
            ->add('lastName', TextColumn::class)
            ->createAdapter(ArrayAdapter::class, [
                ['firstName' => 'Donald', 'lastName' => 'Trump'],
                ['firstName' => 'Barack', 'lastName' => 'Obama'],
            ])
            ->handleRequest($request);

        if ($table->isCallback()) {
            return $table->getResponse();
        }

        return $this->render('users/test.html.twig', ['datatable' => $table]);
    }
}

您不应该扩展
AbstractController
：

use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class MyClass extends Controller{}

我更改代码。我的类扩展了AbstractController。我复制并粘贴了您的，但我有一个错误语法，用于“受保护的datatableFactory；公共函数uu构造（datatableFactory$datatableFactory）{$this->datatableFactory=$datatableFactory；}”添加使用Omines\DataTableBundle\datatableFactory？是，我添加了“use Omines\DataTablesBundle\DataTableFactory”删除use DataTablesTrait；并将$this->createDataTable（）更改为$this->datatableFactory->create（[]），检查捆绑服务是否正常工作<代码>php bin/控制台调试：容器
class UsersController extends AbstractController
{
    use DataTablesTrait;
    protected datatableFactory;
    public function __construct(DataTableFactory $datatableFactory) {
       $this->datatableFactory = $datatableFactory;
    }

    /**
     * @Route("/admin/user/test", name="users_test")
     */
    public function usersTest(Request $request){
        $table = $this->createDataTable()
            ->add('firstName', TextColumn::class)
            ->add('lastName', TextColumn::class)
            ->createAdapter(ArrayAdapter::class, [
                ['firstName' => 'Donald', 'lastName' => 'Trump'],
                ['firstName' => 'Barack', 'lastName' => 'Obama'],
            ])
            ->handleRequest($request);

        if ($table->isCallback()) {
            return $table->getResponse();
        }

        return $this->render('users/test.html.twig', ['datatable' => $table]);
    }
}

use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class MyClass extends Controller{}
