Jackson JSON serializer: enable or disable serialisation of certain field in runtime?

I have trivial object serialization via Jackson library: 

    ObjectMapper objectMapper = new ObjectMapper();
    String jsonText = objectMapper.writeValueAsString(myComplexObject);

I have one field in myComplexObject that I sometimes do not want to edn up in serialized result. I know that I can avoid serialization completely if I declare a field in myComplexObject with @JsonIgnore, but I need that field sometimes present in the JSON. Can I achieve this effect? I can assign that field to NULL or to some other special value in case I do not need it.

Quite a few ways, from simple JSON Views to @JsonFilter, explained at "Every day Jackson usage, part 3: Filtering properties" (and its followup, "Advanced filtering with Jackson, Json Filters")
