JMS Serializer exclude public properties

Question

I have a class I want to serialize, but exclude a public property. So far I tried @Exclude but I did not work (see Result).

Any ideas how to solve this problem?

Entity:

class Checkout extends Entity
{
    /**
     * @Exclude()
     */
    public $normalizerCallbacks = [
        'a' => 1,
        'b' => 2,
    ];

    ..........

Serialize:

$checkout = $this->getDoctrine()->getRepository('App:Checkout')->find($id);

$serializer = $this->get('jms_serializer');
$data = $serializer->serialize($checkout, 'json');

Result:

{
    normalizer_callbacks: {
        a: 1
        b: 2
    }
}

use JMS\Serializer\Annotation as JMS;

/**
 * User
 *
 * @ORM\Table(name="checkout", options={"collate"="utf8_general_ci"})
 * @ORM\Entity
 *
 * @JMS\ExclusionPolicy("none")
 */
class Checkout extends Entity
{
    /**
     * @JMS\Exclude();
     */
    public $normalizerCallbacks = [

1. Add to "jms/serializer-bundle": "^1.0" composer and run update
2. Add new JMS\SerializerBundle\JMSSerializerBundle() to AppKernel
3. Add jms_serializer.camel_case_naming_strategy.class: JMS\Serializer\Naming\IdenticalPropertyNamingStrategyto parameters.yml
4. Then used it as in Serialize

Try whether you included it correctly:

use JMS\Serializer\Annotation as JMS;

and then use it like:

@JMS\Exclude();

in your annotation.

As well make sure your class is annoted with @ExclusionPolicy("none") (see http://jmsyst.com/libs/serializer/master/reference/annotations).

You can as well do it the other way round, specifically @Expose while class is annotated with @ExlucsionPolicy("all").

Make sure to clean your cache before re-testing it.
