Format LocalDateTime with spring, jackson - spring

Question

In a spring rest application, i send a objet who contain a date
{ appointmentId: "", appointmentTypeId: "1", appointmentDate:
"2015-12-08T08:00:00-05:00" }
In my dto side
for my appointmentDate i have
#DateTimeFormat(iso=DateTimeFormat.ISO.DATE_TIME)
#JsonDeserialize(using = LocalDateTimeDeserializer.class)
private LocalDateTime appointmentDate;
In my dependencies i have
jackson-datatype-jsr310-2.6.3
I get this error
rg.springframework.http.converter.HttpMessageNotReadableException:
Could not read document: Text '2015-12-08T13:00:00.000Z' could not be
parsed, unparsed text found at index 23 (through reference chain:
server.dto.AppointmentDto["appointmentDate"]); nested exception is
com.fasterxml.jackson.databind.JsonMappingException: Text
'2015-12-08T13:00:00.000Z' could not be parsed, unparsed text found at
index 23 (through reference chain:
server.dto.AppointmentDto["appointmentDate"])
tried only with DateTimeFormat, only with JsonDeserialize and both, but get the same error.
Edit
#RequestMapping(value = "/rest")
#RestController
public class LodgerController {
#RequestMapping(value = "/lodgers/{lodgerId}/appointments", method = RequestMethod.POST)
public Long createAppointmentsByLodgerId(#PathVariable("lodgerId") Long lodgerId, #RequestBody AppointmentDto appointmentDto) {
return appointmentService.save(appointmentDto);
}
}
public class AppointmentDto {
private Long appointmentId;
private Long appointmentTypeId;
private Long lodgerId;
#JsonDeserialize(using = LocalDateTimeDeserializer.class)
private LocalDateTime appointmentDate;
public AppointmentDto() {
}
}
<form id="lodgerAppointmentForm" class="form-horizontal" role="form">

<input type="hidden" id="lodgerAppointmentId" name="appointmentId">

</form>
var locale = navigator.languages ? navigator.languages[0] : (navigator.language || navigator.userLanguage);
moment().locale(locale);
$('#appointmentDatepicker').datetimepicker({
format: 'DD/MM/YYYY H:mm',
allowInputToggle: true
});
var lodgerId = $('#lodgerId').val();
var type = "post";
var url = "http://localhost:8080/rest/lodgers/" + lodgerId + "/appointments";
var data = transForm.serialize('#lodgerAppointmentForm');
data.appointmentDate = $('#appointmentDatepicker').data('DateTimePicker').date().format();
data.lodgerId = lodgerId;
data = JSON.stringify(data);
jQuery.ajax({
type: type,
url: url,
contentType: "application/json",
data: data,
success: function (data, status, jqXHR) {
},
error: function (jqXHR, status) {
}
});
transform.js come from https://github.com/A1rPun/transForm.js/blob/master/src/transForm.js
bootstrap datetimepicker come from https://github.com/Eonasdan/bootstrap-datetimepicker
Moment use 2015-12-09T08:00:00-05:00 (ISO 8601)
DateTimeFormatter.ISO_LOCAL_DATE_TIME who is: 2015-12-09T08:00:00 (ISO 8601)
both don't seem to use the same format

I think that your problem is described here:
https://github.com/FasterXML/jackson-datatype-jsr310/issues/14
I encounter the same error when was playing around with LocalDateTime and REST API. The problem is that you can serialize LocalDateTime to something like this:
2015-12-27T16:59:29.959
And you can create valid Date object in JavaScript from that string.
On the other hand if you try to POST/PUT JavaScript date to server then this:
var myDate = new Date();
JSON.stringify(myDate);
will create string like this (with extra Z - which stands for zulu time/UTC time zone):
2015-12-27T16:59:29.959Z
And that extra time zone info causes error in your case during deserialization because LocalDateTime don`t have time zone.
You can try to use ZonedDateTime on ther server or format by yourself date string on client side before sending (without Z suffiks).
