Spring throws ConverterNotFound for range search on date in MongoDB

问题

I'm trying to do a range search on DateTime data format. The dates are being stored in Joda's DateTime format in the MongoDB.

When I do a FIND query for a data greater than a given date, the ConverterNotFoundException is being thrown.

Could someone please share information on why the conversation of Date object is being done to DateTime (Joda) &how can I possibly resolve this?

Exception

org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type java.util.Date to type org.joda.time.DateTime

Application Code

Query query = new Query();
        DateTime dateTest = new DateTime(2014, 1, 1, 0, 0);
            query.addCriteria(Criteria.where("monthYear").gte(dateTest.toDateTimeISO()));
        System.out.println(query.toString());
        List<Model> spendingsList = dbConfig.getMongoOperations().find(query, Model.class, collectionName);

The generated query looks like below:

Query: { "monthYear" : { "$gte" : { $java : 2014-01-01T00:00:00.000+01:00 } } }, Fields: null, Sort: null

Annotation used in the Model class

@DateTimeFormat(iso = ISO.DATE_TIME)
    private DateTime monthYear;

After investigating this behavior, found the following issues and solutions.

Issue

The data stored in the MongoDB is interpreted differently when the data type is read from different MongoDB UIs. Eg: Mongovue interprets the type as DateTime, DBeaver interprets it as Timestamp

Solution Query the DB from the application with the date time object in Date format.

Example

int year;
DateTime monthYearFrom = new DateTime(year, 1, 1, 1, 0);
DateTime monthYearTo = new DateTime((year+1), 1, 1, 1, 0);
query.addCriteria(Criteria.where("monthYear").gte(monthYearFrom.toDate()).lte(monthYearTo.toDate()));
