Json Deserialization of string "2023-11-10 23:01:18.940" to calendar

Question

I am trying to deserialize json String date to Calendar and deserialization is working however it is not what i want.

Current Behaviour

@JsonProperty("systemDt")
@JsonFormat(Pattern="yyyy-MM-dd HH:mm:ss.SSS")
Calendar responseDateTime;

Deserializes to responseDateTime=java.util.GregorianCalendar[time=1141556400000,areFieldsSet=true,areAllFieldsSet=true,lenient=true,zone=sun.util.calendar.ZoneInfo[id="UTC"......

I want a Simple Calendar Date of the format yyyy-MM-dd HH:mm:ss.SSS

You should been using LocalDateTime property in code. eg:

public static void main(String[] args) {
        DateTimeFormatter dateFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS");
        System.out.println(LocalDateTime.now().format(dateFormatter));
    }

output:

2023-11-30 10:59:47.852

final:

@JsonProperty("systemDt")
@JsonFormat(Pattern="yyyy-MM-dd HH:mm:ss.SSS")
private LocalDateTime responseDateTime;
