Date format Mapping to JSON Jackson

You can use the @JsonFormat annotation to specify the format of date fields in a JSON payload when serializing or deserializing using Jackson.

Here is an example of how you can use @JsonFormat to specify the format of a java.util.Date field:

import com.fasterxml.jackson.annotation.JsonFormat;

public class MyClass {
    @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'")
    private Date date;
}

This will format the date field in the JSON payload as a string in the format "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", which is a common format used for dates in JSON.

You can also use @JsonFormat to specify the time zone for the date field, using the timezone attribute.

import com.fasterxml.jackson.annotation.JsonFormat;

public class MyClass {
    @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", timezone = "UTC")
    private Date date;
}

This will format the date field in the JSON payload as a string in the specified format, in the UTC time zone.
