Is it possible to set the default date format in JSON-B (Yasson) globally, instead of adding an annotation on every property? - jersey

Question

I have using Jersey so far and I am doing my first implementation with JSON-B.
I am using Payara, so I working with Jersey and Yasson. I had an issue, because the serialized dates would always contain the "[UTC]" suffix.
I have managed to use an annotation on my date property, in my DTO. But I would like to configure that globally (in the JAX-RS application config?), instead of repeating myself on every date property. Is that possible? I haven't found anything so far...
Side question: I assume that it is possible to get rid of this "[UTC]" suffix, since it breaks all clients trying to parse the date. Any idea?

Thanks to this Github issue, I was able to solve my problem. Here is what I ended up writing in my code:
JSONConfigurator.java:
import javax.json.bind.Jsonb;
import javax.json.bind.JsonbBuilder;
import javax.json.bind.JsonbConfig;
import javax.json.bind.config.PropertyNamingStrategy;
import javax.ws.rs.ext.ContextResolver;
import javax.ws.rs.ext.Provider;
#Provider
public class JSONConfigurator implements ContextResolver<Jsonb> {
#Override
public Jsonb getContext(Class<?> type) {
JsonbConfig config = getJsonbConfig();
return JsonbBuilder
.newBuilder()
.withConfig(config)
.build();
}
private JsonbConfig getJsonbConfig() {
return new JsonbConfig()
.withDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSXXX", null);
}
}
And:
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
import java.util.HashSet;
import java.util.Set;
#ApplicationPath("/api")
public class ApplicationConfig extends Application {
#Override
public Set<Class<?>> getClasses() {
Set<Class<?>> resources = new HashSet<Class<?>>();
addRestResourceClasses(resources);
resources.add(JSONConfigurator.class);
return resources;
}
private void addRestResourceClasses(Set<Class<?>> resources) {
...
}
}
