JMS Serializer Config

Question

I am using this in config.yml:

# JMSSerializer Configuration
jms_serializer:
    #parameters:
        #jms_serializer.camel_case_naming_strategy.class: JMS\Serializer\Naming\IdenticalPropertyNamingStrategy
    metadata:
        cache: file
        debug: "%kernel.debug%"
        file_cache:
            dir: "%kernel.cache_dir%/serializer"
        auto_detection: true
        directories:
            AppBundle:
                namespace_prefix: "AppBundle"
                path: "%kernel.root_dir%/config/serializer/AppBundle"

And this in Entity.Category.yml:

AppBundle\Entity\Category:
exclusion_policy: ALL

But when i try to send request, i receive this error:

Expected metadata for class AppBundle\\Entity\\Category to be defined in /var/www/test/app/config/serializer/AppBundle/Entity.Category.yml.

How can I solve this issue?

It looks like you are getting an incorrect path to your project files with %kernel.root_dir% . Make sure that /var/www/test/app is the correct path to your project. Check your PHP __DIR__ constant and try replacing `%kernel.root_dir% with what that says as well as what you think the path should be.

Also, instead of defining your exclusion policy in a config file you should just be able to annotate your entity like so and expose things as needed:

use JMS\Serializer\Annotation as JMS;

/**
 * Class ExampleEntity
 *
 * @JMS\ExclusionPolicy("all")
 * @ORM\Entity()
 */
class ExampleEntity
{
}

JMS annotations are foundhere .
