ObjectMapper readValue always adds time zone at the end of XMLGregorianCalendar from a JSON date string

Question

I am writing a junit test case which I need to give the following data file (request):

  data_file:

  {
    "birthDate" : "2017-12-08"
   }

The junit test file uses:

     fasterxml.jackson.databind.ObjectMapper.readValue(data_file) 

to read this request data file and convert the date into XMLGregorianCalendar. However, the converted value has a "Z" at the end, I think that is the default time zone:

     2017-12-08T00:00:00.000Z

I can't change the java class that contains the code for reading the Json value because we don't own the code. So what date string should I give in my test data file so that the "Z" won't appear at the end of converted XMLGregorianCalendar value?

     2017-12-08T00:00:00.000

Many Thanks.

I don’t know how your JSON mapper gets to the result it does. I tried:

    System.out.println(
            DatatypeFactory.newInstance().newXMLGregorianCalendar("2017-12-08"));

This prints

2017-12-08

No offset from UTC and also no time of day, just the same string as I fed into the XMLGregorianCalendar.

However, once you have got an XMLGregorianCalendar, say, xgc, you can remove the offset by setting it to undefined:

    xgc.setTimezone(DatatypeConstants.FIELD_UNDEFINED);

Now the toString method will produce a string without the Z in the end.
