Force Milliseconds When Serializing Instant to ISO8601 using Jackson

Question

I have some questions related to JSON serialization using Jackson in a project where I use Spring Boot 2.0.0.M6, Spring Framework 5.0.1.R

Answer 1

Rather than fixing the bug of Jackson library, following could be a quick work around: Create a string variable in the POJO class where you have Timestamp variable:

private Timestamp createTimeStamp;

private String stringCreateTimeStamp;   

capture timestamp value as a string:

listOfPojo.forEach(pojo-> {
            pojo.setStringCreateTimeStamp(request.getcreateTimeStamp().toString());
        });
