Could not save date field as ISO date in mongo db

问题:

I have pojo like this:

@Document(collection = "data")
public class DataPoint {
    @Id
    private String id;
    private LocalDateTime createdDate;
    ....
}

in some code base I have following code:

@Autowired
private ProducerTemplate producerTemplate;

...

final List<DataPoint> dataPoints =....
producerTemplate.sendBody("mongodb:mongoBean?database=" + mongoDataConfiguration.getDatabase()
                                    + "&createCollection=true&operation=insert&collection=" + mongoDataConfiguration.getDataPointCollection(), 
        dataPoints);

But when I open collection in database I see date field like this:

"createdDate" : {
                "month" : "NOVEMBER",
                "year" : 2017,
                "dayOfMonth" : 7,
                "dayOfWeek" : "TUESDAY",
                "dayOfYear" : 311,
                "monthValue" : 11,
                "hour" : 17,
                "minute" : 55,
                "nano" : 259000000,
                "second" : 21,
                "chronology" : {
                        "id" : "ISO",
                        "calendarType" : "iso8601"
                }

But I want to store usual ISO date recognizable for mongoDB. It should be something like this:

ISODate("2017-11-06T12:47:51.720")

How did I try to resolve this issue?

1:
I read this topic:

Thus I created a custom serializer:

public class IsoDateSerializer extends JsonSerializer<DateTime> {
    @Override
    public void serialize(DateTime value, JsonGenerator jgen, SerializerProvider provider) throws IOException {
           jgen.writeStartObject();
        serializeContents(value.toDate(), jgen, provider);
        jgen.writeEndObject();
    }
    private void serializeContents(Date value, JsonGenerator jgen, SerializerProvider provider) throws IOException {
        jgen.writeFieldName("$date");
        SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
        String formattedDate = formatter.format(value);
        jgen.writeString(formattedDate);
    }
}

and registered it correctly:

@JsonSerialize(using = IsoDateSerializer.class)
public DateTime getCreatedDate() {
    return new DateTime(Date.from(createdDate.toInstant(ZoneOffset.UTC)));
}

But it throws exception:

Then I need to write:

 .marshal(jackson) 
        .convertBodyTo(String.class)

but looks like producerTemplate doesn't have appropriate API.

Ok, I understand the cause of exception. @Neil Lunn said that it is because names started with $ - reserved.

2.

I created a topic Could not save date field as ISO date in mongo db via Camel (Caused by: java.lang.IllegalArgumentException: Invalid BSON field name $date)

According @Neil Lunn advices I tried to do

a) return Date in model: 

public DateTime getCreatedDate() {
        return new DateTime(Date.from(createdDate.toInstant(ZoneOffset.UTC))).toDate();        
    }

It lead to saving date as NumberLong

b) tried to change $date with myDate in serializer but it lead to saving date as usual string

с)

Also I tried to change date format in serializer according @Neil Lunn advic in previous question:

private void serializeContents(Date value, JsonGenerator jgen, SerializerProvider provider) throws IOException {
    jgen.writeFieldName("mydate");
    SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
    String formattedDate = formatter.format(value);
    jgen.writeString("ISODate("  +formattedDate + ")");
}

But it still doesn't work and I see:

"createdDate" : {
                "mydate" : "ISODate(2017-11-08T13:15:06)"
        },

in mongo-shell

Please, help to struggle this issue?

P.S.

When I use spring-data - date stores right now without additional movements
