Without this code works fine:
public List<Model> getByPeriod(String field, Date from, Date to) {
return mongo.find(new Query(Criteria.where(field).gte(from)
.and(field).lt(to)), getModelClass());
Fails also for
//...
.where(field).gte(from).lt(to)//...
But similar code works fine for other cases.
I have tried your code, it is working for return mongo.find(new Query(Criteria.where(field).gte(from).lt(to)), getModelClass());
but not working for
return mongo.find(new Query(Criteria.where(field).gte(from).and(field).lt(to)), getModelClass());
The error I am getting is Due to limitations of the com.mongodb.BasicDBObject, you can't add a second 'field' expression specified as 'field : { "$lt" : { "$date" : "2017-11-03T12:36:54.216Z"}}'. Criteria already contains 'field : { "$gte" : { "$date" : "2017-11-02T12:36:54.216Z"}}'.
Hence the conclusion is remove .and(field)
from the query.
FYI : from = yesterday and to = now for me.
