Question

我尝试按照本教程进行分页：https://knpuniversity.com/screencast/symfony-rest3/pagerfanta-pagination

目前我安装了white-october/pagerfanta-bundle，当我创建我的用户存储库时如下：

<?php
// src/UsersBundle/Repository/UserRepository.php
namespace UsersBundle\Repository;


use Doctrine\ORM\EntityRepository;

class UserRepository extends EntityRepository {

    public function findAllQueryBuilder() {
        return $this->createQueryBuilder('user');
    }

}

在我的控制器动作中我这样做了：

<?php
// src/UsersBundle/Controller/UsersController.php

namespace UsersBundle\Controller;

// use statements ...

/**
 * Class UsersController
 *
 * @package UsersBundle\Controller
 *
 * @Rest\RouteResource("user", pluralize=false)
 * @Rest\NamePrefix( "api_v1_" )
 */
class UsersController extends FOSRestController implements ClassResourceInterface {

    // ...

    /**
     * Responsible to list all the registered users.
     *
     * @Rest\QueryParam(name="page", default="1", requirements="\d+",nullable=true)
     *
     * @return array|\Traversable
     */
    public function getListAction( ParamFetcher $param_fetcher ) {
        if ( ! $this->isGranted( 'ROLE_ADMIN' ) ) {
            throw new UnauthorizedHttpException( 'You do not have sufficient permission to access this resource' );
        }

        $qb = $this->getDoctrine()
            ->getRepository('UsersBundle\Repository\UserRepository')
            ->findAllQueryBuilder();

        $adapter = new DoctrineORMAdapter( $qb );

        $users = $this->user_manager->findUsers();

        return $users;
    }

    // ...

}

我得到了这个输出：

{"code":500,"message":"The class 'UsersBundle\\Repository\\UserRepository' was not found in the chain configured namespaces UsersBundle\\Entity, FOS\\UserBundle\\Model"}

任何人都知道输出意味着什么？不幸的是，我对Symfony完全不熟悉，我无法理解这个输出的问题是什么。

$qb = $this->getDoctrine()
        ->getRepository('UsersBundle\Repository\UserRepository')
        ->findAllQueryBuilder();

你应该通过你的实体找到你的存储库，所以像这样的

$qb = $this->getDoctrine()
        ->getRepository('User:class')
        ->findAllQueryBuilder();

Doc：https://symfony.com/doc/current/doctrine.html#fetching-objects-from-the-database

在你的User实体中你应该有类似的东西

/**
 * @ORM\Table(name="User")
 * @ORM\Entity(repositoryClass=UserRepository::class)
 */
class User {
...

Symfony：在链配置的命名空间中找不到类* UsersBundle \ Entity，FOS \ UserBundle \ Model
