Problem

Using Spring data and Mongodb, below is a function to find data within a date range.

public List<RequestAudit> findByIpAndDate(String ip, Date startDate, Date endDate) {

    Query query = new Query(
        Criteria.where("ip").is(ip)
        .andOperator(Criteria.where("createdDate").gte(startDate))
        .andOperator(Criteria.where("createdDate").lt(endDate))
    );

    return mongoOperation.find(query, RequestAudit.class);

}

It hits following error message :

org.springframework.data.mongodb.InvalidMongoDbApiUsageException:
    Due to limitations of the com.mongodb.BasicDBObject, you can't add a second '$and'
    expression specified as '$and : [ { "createdDate" : { "$lt" : { "$date" : "2013-02-25T16:00:00.000Z"}}}]'.
    Criteria already contains '$and : [ { "createdDate" : { "$gte" : { "$date" : "2013-02-24T16:00:00.000Z"}}}]'

Solution

Adding multiple “$and” operators on the same field “createdDate” will make Spring interprets it into a wrong mongodb query. To fix it, change the query to follow :

Query query = new Query(
    Criteria.where("ip").is(ip)
    .andOperator(
        Criteria.where("createdDate").lt(endDate),
        Criteria.where("createdDate").gte(startDate)
    )
);

For multiple criteria on the same field, uses a “comma” to combine them.
