Symfony2类不是有效实体或映射超类

Question

I'm new to symfony2 and trying to execte the command in neatbeans

console doctrine:generate:entities /backend/storeBundle/Entity/RolClass

it's shown the error:

[Doctrine\ORM\Mapping\MappingException]
Class "\backend\storeBundle\Entity\RolClass" is not a valid entity or 
mapped super class.                                                               

The class:

<?php
namespace backend\storeBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
 * @ORM\Entity
* @ORM\Table(name="nomrol")
*/
  class RolClass {
/**
 * @ORM\Column(type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
protected $id;
/**
 * @ORM\Column(type="string",length=100)
 */
protected $namerolcust;
}

Searching info in this page I tried to modify the app/config.yml:

orm:
    auto_generate_proxy_classes: "%kernel.debug%"
    default_entity_manager: default
    entity_managers:
        default:
            mappings:
                backendstoreBundle: ~

Firstly it is bad practice to use CLass in you class name, please remove ;)

1) do the above an then re-run

2) If that still fails then for some reason then alter you config.yml to

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

Now if that fails for some strange reason you doctrine is looking for a superclass so you will have to do the following.

Define the base-class:

/**
 * @ORM\MappedSuperclass
 */
abstract class BaseRol
{
    // base rol
}

Then extend your class

/**
 * @ORM\Entity
 */
class Rol extends Baserol
{
    // rol
}

Because you're missing the @MappedSuperclass annotation on the base-class, Doctrine throws the exception you mention.
