Migrating symfony 3.4 to 4.4 doctrine not a valid entity or mapped super class issue-CodePudding

I've migrated from symfony 3.4 to 4.4 moved from using bundles to /src I'm having an issue with the Entity with this error

    Uncaught PHP Exception Doctrine\ORM\Mapping\MappingException: "Class 
    "App\Entity\Regions" is not a valid entity or mapped super class.

my Entity looks like this. I'm wondering whether this is because it can't find the orm.xml? or something else? it was in bundle/Resources. Also the Doctrine\ORM\Mapping as ORM (say's not used) is the orm.xml correct, the link here seems to show very different schema tags https://symfony.com/doc/4.4/reference/configuration/doctrine.html

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;
/**
 * @ORM\Entity
 * @ORM\Table(name="Regions")
 */

/**
 * Regions
 */
class Regions
{
    /**
     * @var int
     */
    private $id; 

    /**
     * @var string
     */
    private $region;
    /**
     * Get id.
     *
     * @return int
     */

    public function getId()
    {
        return $this->id;
    }

    public function getRegion()
    {
        return $this->region;
    }
}

querying the entity

$regions = $this->getDoctrine()->getRepository(Regions::class);
$regionInfo = $regions->findOneBy(array('region' => strtolower($regionSearch)));

ORM in /src/Resources/config/doctrine

CodePudding user response：

Your annotations should be set right above the class declaration:

/**
 * Regions
 * @ORM\Entity
 * @ORM\Table(name="Regions")
 */
class Regions

With your current file, only the first docblock is read and as it is missing the @ORM\Entity annotation, Doctrine considers it isn't a valid entity class.
