Element in JSON of type date is being sent as timestamp instead of date - json

Question

I am converting the json received from database to object User.class using Objectmapper,class structure as follows
#XmlRootElement
public class User {
public User() {
super();
}
#XmlElement
private String username=null;
#XmlElement
private Feedbacks feedbacks=null;
//getter setter....
}
User has an instance of Feedbacks class which in turn has Arraylist< Feedback>
#XmlRootElement
public class Feedbacks {
public Feedbacks() {
}
#XmlElement
private ArrayList<Feedback> FeedbackList=new ArrayList<>();
public ArrayList<Feedback> getFeedbackList() {
return FeedbackList;
}
public void setFeedbackList(ArrayList<Feedback> FeedbackList) {
this.FeedbackList = FeedbackList;
}
}
and
public class Feedback {
private String feedback=null;
//private String timeStamp=null;
/*#JsonDeserialize(using = DateDeserializer.class); */
#JsonFormat(pattern = "MM/dd/yyyy HH:mm")
private Date feedbackDate;
public Feedback (){}
}
Sample json that i retrieve from db is:
{
"userName":"Test",
"feedbacks":{
"feedbackTOList":[
{
"feedback":"Please select appropriate value..1",
"timeStamp":"03/01/2000 14:52"
},
{
"feedback":"Please select appropriate value..2",
"timeStamp":"03/01/2018 13:50"
},
{
"feedback":"Please select appropriate value..3",
"timeStamp":"02/01/2018 10:52"
}
]
}
}
Json to object conversion and sorting the list of feedback based on date:
SimpleDateFormat formatter = new SimpleDateFormat("MM/dd/yyyy HH:mm");
mapper = new ObjectMapper();
mapper.setDateFormat(formatter);
userObject= mapper.readValue(jsonPayload, User.class);
Collections.sort(user.getFeedbacks().getFeedbackList(), new
Comparator<Feedback>() {
public int compare(Feedback f1, Feedback f2) {
if (f1.getTimeStamp() == null || f2.getTimeStamp() == null)
return 0;
return (f2.getTimeStamp().compareTo(f1.getTimeStamp()));
}
});
The issue is when angular UI consumes the object from rest service,instead of Date (Wed Aug 01 16:20:00 EDT 2018]) the timestamp value is being sent as timeStamp=1533154800000.
My question is how do i send the string in given format or atleast date object but not timestamp?
So far i tried #JsonFormat(pattern = "MM/dd/yyyy HH:mm"),custom date deserializer but no luck(by referring many other posts on stackoverflow,sites),can some one please let me know what mistake am i making?
