Symfony 2 - 类“Mingle \ StandardBundle \ Entity \ Product”不是有效实体或映射超类

Question

I created a Product.php file in my bundle Mingle\StandardBundle\Entity like this:

<?php

namespace Mingle\StandardBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

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

class Product
{
    /*
     * @ORM\Column(type="integer")
     * @ORM\ID
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;
    /*
     * @ORM\Column(type="string",length=100)
     */
    protected $name;
    /*
     * @ORM\Column(type="decimal",scale=2)
     */
    protected $price;
    /*
     * @ORM\Column(type="text")
     */
    protected $description;
}
?>

In Ubuntu Terminal, at root folder of Symfony project, I typed this command:

php app/console doctrine:generate:entities Mingle/StandardBundle/Entity/Product

And I encountered problem:

[Doctrine\ORM\Mapping\MappingException]                                      
  Class "Mingle\StandardBundle\Entity\Product" is not a valid entity or mapped super class.

And I don't know how to solve even after searching. Please help

Annotations have to be placed inside /** */ comment block, otherwise they are not recognized.
