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

This was already mentioned in FAQ first answer points to, but just in case: you can choose between numeric and textual representation (numeric being used by default since it is much faster) by using this feature:

objectMapper.configure(SerializationConfig.Feature.WRITE_DATES_AS_TIMESTAMPS, false);

doing this will use the default date format, which you can then redefine as mentioned (with setDateFormat).

Also: you can simplify you code like so:

ObjectMapper mapper = new ObjectMapper();
mapper.configure(SerializationConfig.Feature.INDENT_OUTPUT, true);
mapper.configure(SerializationConfig.Feature.WRITE_DATES_AS_TIMESTAMPS, false);
return mapper.writeValueAsString(object);

instead of using StringWriter and JsonGenerator explicitly.
