How to fix class is not a valid entity or mapped super class?

问题

So I'm trying to follow symfony2's tutorial on doctrine for my own website and modeling my User entity after their Product one.

Also, before anyone marks this a duplicate, I have already tried the solutions given in numerous other questions with no luck:

Not a valid entity or mapped super class
Doctrine class is not a valid entity or mapped super class
Symfony/Doctrine: Class is not a valid entity or mapped super class
symfony2 is not a valid entity or mapped super class
Symfony/Doctrine: Class is not a valid entity or mapped super class
"Class XXX is not a valid entity or mapped super class" after moving the class in the filesystem

and the list goes on

I have my entity class:

<?php
    namespace MySite\MyBundle\Entity;

    use Doctrine\ORM\Mapping as ORM;

    /**
     * @ORM\Entity
     * @ORM\Table(name="user")
     */
    class User
    {
        /**
         * @ORM\Column(type="integer")
         * @ORM\Id
         * @ORM\GeneratedValue(strategy="AUTO")
         */
        protected $id;

        /**
         * @ORM\Column(type="string", length=100)
         */
        protected $name;

        /**
         * @ORM\Column(type="string", length=64)
         */
        protected $password;
    }
?>

Now, I'm running the command:

$ php app/console doctrine:generate:entities MySite/MyBundle/Entity/User

to generate the accessor methods. However, when I do this, I get the error:

[Doctrine\ORM\Mapping\MappingException]
Class "MySite\MyBundle\Entity\User" is not a valid entity or mapped super class.

Ok, I figured it out myself. My problem is that my config.yml was wrong. I was missing the auto_mapping: true line in my config.yml.

doctrine:
    # (dbal stuff here)

    orm:
        auto_generate_proxy_classes: "%kernel.debug%"
        auto_mapping: true

After adding that, everything auto-generates fine with the php app/console doctrine:generate:entities MySite/MyBundle/Entity/User line

回答2:

I had a similar issue and I found at the end the problem in my case was I missed the class that extends Bundle

namespace Acme\TagBundle;

use Symfony\Component\HttpKernel\Bundle\Bundle;

class AcmeTagBundle extends Bundle
{
}

and declaring that class in AppKernel.php under the bundles array.

My problem was that I named the folder entity instead of Entity. When I fixed that it worked like a charm.
