How to marshall null fields in Jersey JAX-RS implementation?

Question

In a Glassfish/Jersey JAX-RS web application, how can I instruct the JSON provider (which defaults to MOXy in Jersey 2.22) to marshall null fields with JSON null value instead of skip them? I understand the use of @XmlElement(nillable = true), but since I need it for all classes fields it would be quite cumbersome to add it everywhere.

You can use MOXy @XmlNullPolicy:

@XmlNullPolicy(emptyNodeRepresentsNull = true, nullRepresentationForXml = XmlMarshalNullRepresentation.EMPTY_NODE)

Do I need to add @XmlNullPolicy to all fields/classes? I'm looking for a configuration option to set this behaviour globally. – Giovanni Lovato Oct 19 '15 at 06:59
I don't know any option like that. – Imperative Oct 19 '15 at 11:24
