ISO 8601 Timestamps with Jackson

By default the mapper serializes Dates as a numeric values. To get ISO-8601 formats use JavaTimeModule and set SerializationFeature.WRITE_DATES_AS_TIMESTAMPS... Note the following configuration supports Durations too!

ObjectMapper mapper = new ObjectMapper();
mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
mapper.registerModule(new JavaTimeModule());

example output:
