Support specify serializer for 3rd classes

Support specify serializer for 3rd classes:

@FurySerialization(targetClass = ThirdPartyBar.class, serializer = ThridPartyBarSerializer.class)
public class ThirdPartyFooConfig {
}

[chaokunyang]

@zhfeng Seems ThirdPartyFooConfig won't be captured by quarkus, does this means if a class is not visited by application main entrance, it won't be identified by quarkus at deployment?

[zhfeng]

@chaokunyang Hmm, I don't understand here. What is the class not visisted?

[chaokunyang]

I congifured ThirdPartyBar with ThridPartyBarSerializer.class. But it seems ThirdPartyFooConfig annotated configuration class is not scanned by quarkus:

@FurySerialization(targetClass = ThirdPartyBar.class, serializer = ThridPartyBarSerializer.class)
public class ThirdPartyFooConfig {
}

Maybe you can take a look at RegisterForReflection in Quarkus which is very similar with what you want to achive.

[chaokunyang]

It's not about the annotation itself, it's about how to make the class annotated by this annotation got identified by Quarkus

[zhfeng]

Maybe better use

Class<?>[] targetClass() default {};

Updated to this in the new commit. Actually it was my earliest implementation, I thought it may introduce confusion with classId since we can't configure multiple class id but we can configure multiple classes. I added a classId check in the new commit. If multiple classes are specified, no class id are allowed in the annotation config

[zhfeng]

I think serializer need to check as well since I suppose serializer should only to a specfic target class?

[chaokunyang]

Not exactly, multiple classes can share same serializer. This is common, users may write a serializer for an abstract parent class, which can be used for all subclasses serialization
