I have had the same issue recently: to store date as Date object into MongoDB via MongoJack.
First of all, I used MongoJack 2.10.0 version.
And it requires to create own Serializer and Deserializer.
public class Serializer extends JsonSerializer<DateTime> {
@Override
public void serialize(DateTime value, JsonGenerator gen, SerializerProvider serializers) throws IOException {
gen.writeObject(new Date(value.getMillis()));
}
}
public class Deserializer extends JsonDeserializer<DateTime> {
private static final DateDeserializer DATE_DESERIALIZER = new DateDeserializer();
@Override
public DateTime deserialize(JsonParser p, DeserializationContext ctxt) throws IOException, JsonProcessingException {
Date date = DATE_DESERIALIZER.deserialize(p, ctxt);
return date == null ? null : new DateTime(date);
}
}
.....
@JsonSerialize(using = Serializer.class)
@JsonDeserialize(using = Deserializer.class)
private DateTime testDate;
public DateTime getTestDate() {
return testDate;
}
public void setTestDate(DateTime testDate) {
this.testDate = testDate;
}
......
In my case, I converted Date into joda DateTime to keep consistency with my code but it's possible to change to another type (LocalDateTime, OffsetDateTime, etc.)
