json string with multiple types to Map[String, Object]

Question

I have this json string:

{
  "startDate" : "2014-12-17T14:31:40Z",
  "name" : "Izek",
  "age" : 12
}

When I convert it with Jackson to Map[String, Object] the type of startDate is String how I can tell Jackson to convert it to DateTime type?

Answer 1

You need to explicitly set the data format in the objectMapper. You could refer Date format Mapping to JSON Jackson for more details. Alternately, you could do it as http://java.dzone.com/articles/how-serialize-javautildate

Answer 2

Have you considered a custom map deserializer? You can try to parse the date in there. If not known in advance, you'll probably hit a performance hit here.
