Spring Boot Jackson and Data serialization

Question

In my Spring Boot application I use a following DTO with @RestController:

public abstract class ComparableQuery extends BaseQuery {

    private final Object value;

...

}

Everything works fine but when I use Spring RestTemplate and pass java.util.Date as ComparableQuery.value I see that Jackson serialize the date object into the following "magic" number:

"value":1009836000000

Right now I don't understand how the date object serialized into the 1009836000000 number representation and how to emulate it when I use for example AngularJS as a client of my back-end API. Please advise.

I think this is the value of your date and is represented in long. You can receive this value and format it by using simpledateformat or anything equivalent to desired format — CrazyMac, Apr 13 '17 at 14:11
does this property helps? `spring.jackson.date-format=yyyy-MM-dd'T'HH:mm:ss.SSSZ` — Patrick, Apr 13 '17 at 14:21

This is a very similar problem as described in this answer about null handling with jackson and spring boot.

The corresponding configuration for date formatting in application.properties should look like:

spring.jackson.write-dates-as-timestamps=false
