How to make JsonGenerator pretty-print Date and DateTime values?

Question

I\'m using this method to convert any object to a json string:

private String objectToJson(Object object) throws IOException {
        // write JSON
        Stri         


        

Answer 1

Because the epoch timestamp (number of milliseconds since January 1st, 1970, UTC) is the most efficient and accurate representation of the time, nearly all date and time related objects are serialized to it. You can of course overwrite it and if you want to use the format mentioned in the question, you'd need to add the following to your code:

DateFormat myDateFormat = new SimpleDateFormat("hh:mm:ss");
objectMapper.getSerializationConfig().setDateFormat(myDateFormat);
objectMapper.getDeserializationConfig().setDateFormat(myDateFormat);
