Hi there,
I'm trying to use @JsonAppend to programmatically add a field to a POJO
during serialization.
I have :
interface Targetable
class Action implements Targetable
I'm trying to have @JsonAppend(props = {@JsonAppend.Prop(name = "target",
value = TargetWriter.class, type = URI.class)}) applied to all classes that
implements Targetable.
The first thing I tried was simply to add @JsonAppend to my Targetable
interface, but this looks to have no effect when serializing an Action:
@JsonAppend(
props = {
@JsonAppend.Prop(name = "target", value =
TargetWriter.class, type = URI.class)
})
public interface Targetable {
}
Then I tried to use a mix-in class and to apply it to Targetable:
@JsonAppend(
props = {
@JsonAppend.Prop(name = "target", value =
TargetWriter.class, type = URI.class)
})
public static class TargetMixin {}
MAPPER.addMixIn(Targetable.class, TargetMixin.class);
Still no luck. So the last thing I tried is to apply TargetMixin to Action
directly:
MAPPER.addMixIn(Action.class, TargetMixin.class);
And this is working.
My question is: is it possible to apply @JsonAppend to an interface,
without having to list all of its implementations, and ideally without
mix-in (ie. like the first example in my post)?
Thanks a lot!
Clément
