问题
I am attempting to use a custom handler for JMS Serializer Bundle
class CustomHandler implements SubscribingHandlerInterface
{
public static function getSubscribingMethods()
{
return array(
array(
'direction' => GraphNavigator::DIRECTION_SERIALIZATION,
'format' => 'json',
'type' => 'integer',
'method' => 'serializeIntToJson',
),
);
}
public function serializeIntToJson(JsonSerializationVisitor $visitor, $int, array $type, Context $context)
{
die("GIVE ME SOMETHING");
}
}
This does nothing, and does not die. This is how I am registering the handler
$serializer = SerializerBuilder::create()
->configureHandlers(function(HandlerRegistry $registry) {
$registry->registerSubscribingHandler(new MyHandler());
})
->addDefaultHandlers()
->build();
$json = $serializer->serialize($obj, 'json');
My handler is never called and I cannot manipulate the data on serialisation.
回答1:
You need to create a service for this handler:
custom_jms_handler:
class: MyBundle\Serializer\CustomHandler
tags:
- { name: jms_serializer.subscribing_handler }
Then make sure you use the registered JMS serializer service
$json = $this->get('jms_serializer')->serialize($obj, 'json');

I have this which works
$serializer = SerializerBuilder::create()
->configureListeners(function(EventDispatcher $dispatcher) {
$dispatcher->addSubscriber(new ProjectSubscriber($this->container));
$dispatcher->addSubscriber(new UserSubscriber($this->container));
})
->addDefaultListeners()
->addMetadataDir(realpath($this->get('kernel')->getRootDir()."/../") . '/src/Jake/NameOfBundle/Resources/config/serializer')
->build();
return $serializer->serialize($project, 'json');
$project
is my entity.
You can omit this line if you don't have serializer configs
->addMetadataDir(realpath($this->get('kernel')->getRootDir()."/../") . '/src/Jake/NameOfBundle/Resources/config/serializer')
I think my main issue was this ->addDefaultListeners()
.
In config.yml
I have
jms_serializer:
metadata:
auto_detection: true
directories:
NameOfBundle:
namespace_prefix: ""
path: "@JakeNameOfBundle/Resources/config/serializer"
I don't have anthing set up to make JMS a service.
