How to manually add DTO classes for compilation

[doppelrittberger]

Hi I have some DTOs in external libraries where I can not simple add @CompiledJson annotations to. How can I manually define a list of classes for which DSL json generates optimized serializers? I use Java8 version with maven and did not find any solution for this. Best regards Markus

You can create a class which references them and put annotation on it.

Ok, the problem now is that the referenced DTO class has Jackson annotations:

public class Event {
    private final String id;
    private final String name;
    private final byte[] payload;
    private final ZonedDateTime created;

    private Event(String id, String name, byte[] payload, ZonedDateTime created) {
        this.id = id;
        this.name = name;
        this.payload = payload;
        this.created = created;
    }

    @JsonCreator
    public static Event New(String id, String name, byte[] payload, ZonedDateTime created) {
        return new Event(id, name, payload, created);
    }
... (getters)

but DSL json seems to ignore @JsonCreator in this class. I reference it via:

@CompiledJson
public class JsonInit {
    private Event event;

    public Event getEvent() {
        return event;
    }

    public void setEvent(Event event) {
        this.event = event;
    }
}

Any ideas to support this one?

Thanks for your effort :)

You can configure it to recognize some Jackson stuff. I think it should recognize JacksonCreator https://github.com/ngs-doo/dsl-json/blob/master/examples/Jackson/pom.xml#L40

Thanks for the fast support :) I created a test project here: https://github.com/doppelrittberger/dsljson-test But I cannot get it to compile. What am I missing?

Hi there,

one addition: if I delete the JsonInit class which references the Event class which is annotated with @JsonCreator it works. So I think there is a small bug in how the classes are generated. If I move CompiledJsonAnnotationProcessor Line 279 (process @CompiledJson annotation) below the processing of the Jackson/JsonB annotations (Line 285) my example works. Tests seem still to be working. Maybe you can add this fix if its working for you.

Thanks, Markus

Tnx. I'll look when I find some time
