To answer your question directly: To skip a value just annotate it with "@JsonIgnore".
But i guess you want good values, instead of skipping them. To get a good LocalDate from Jackson, confige the ObjectMapper with the following feature: "objectMapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);" and then annotate the LocalDate property with: @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd", timezone = "UTC") This should give you a good LocalDate Value.
