Symfony4 findAll在服务中返回空数组

Question

我有一个问题：我在服务中获得了一个存储库，我在上面做了一个findAll，问题：我得到一个空数组（而我的数据库不是）。 所以我想我做错了什么，希望你能开导我。

<?php
/**
 * Created by PhpStorm.
 * User: thocou
 * Date: 07/03/19
 * Time: 15:05
 */

namespace App\Service;

use App\Entity\RentRelease;
use App\Repository\PropertyRepository;
use Doctrine\Common\Persistence\ObjectManager;

class RentReleaseInsertion
{
private $propertyRepository;
private $manager;

public function __construct(PropertyRepository $propertyRepository, ObjectManager $manager)
{
    $this->propertyRepository = $propertyRepository;
    $this->manager = $manager;
}


public function settingRentReleaseValues()
{
    $property = $this->propertyRepository->findAll();

    dd($property);

    foreach ($property as $prop) {
        $lessees = $prop->getLessees();

        foreach ($lessees as $lessee) {
            $rentRelease = new RentRelease();
            $amount = $prop->getRentExcludingCharges() + $prop->getCharges();

            $rentRelease->setRentRelease($lessee);
            $rentRelease->setAmount($amount);
            $rentRelease->setStatus('Paiement en attente');

            $this->manager->persist($rentRelease);
            $this->manager->flush();
        }
    }
}
}

存储库在这里：

<?php

namespace App\Repository;

use App\Entity\Property;
use Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository;
use Symfony\Bridge\Doctrine\RegistryInterface;

/**
 * @method Property|null find($id, $lockMode = null, $lockVersion = null)
 * @method Property|null findOneBy(array $criteria, array $orderBy = null)
 * @method Property[]    findAll()
 * @method Property[]    findBy(array $criteria, array $orderBy = null, $limit = null, $offset = null)
 */
class PropertyRepository extends ServiceEntityRepository
{
public function __construct(RegistryInterface $registry)
{
    parent::__construct($registry, Property::class);
}
}

尽管我怀疑这是一个非常小的问题，但我并不真正理解问题出在哪里。

编辑：

这是我的实体（我没有告诉你getter setter，因为它是+500行，但它们已经生成）：

Answer 1

您是否检查了您的实体并验证此标头是否存在：

/**
 * @ORM\Entity(repositoryClass="App\Repository\PropertyRepository")
 */
class Property
{
