Answer 1

If you are using the jersey-media-json-binding dependency, which uses Yasson (the official RI of JSR-367) and JAVAX-JSON, you can introduce pretty printing as follows:

import javax.json.bind.Jsonb;
import javax.json.bind.JsonbBuilder;
import javax.json.bind.JsonbConfig;
import javax.ws.rs.ext.ContextResolver;
import javax.ws.rs.ext.Provider;

@Provider
public class RandomConfig implements ContextResolver {
    private final Jsonb jsonb = JsonbBuilder.create(new JsonbConfig().withFormatting(true));

    public RandomConfig() { }

    @Override
    public Jsonb getContext(Class objectType) {
        return jsonb;
    }
}
