I use spring data mongodb.
I want the records between two dates. The following MongoDB Query works:
db.posts.find({startDate: {$gte: start, $lt: end}});
My attempted Spring data query object code translation does not work:
Query query = new Query();
query.addCriteria(Criteria.where("startDate").gte(startDate)
.and("startDate").lt(endDate));
What is the correct order of method calls to build the Mongo query I need?
回答1:
Do not include the 'and("startDate")' part in your criteria.
Instead of :
query.addCriteria(Criteria.where("startDate").gte(startDate).and("startDate").lt(endDate));
You should use:
query.addCriteria(Criteria.where("startDate").gte(startDate).lt(endDate));
When you include the 'and("startDate")' part, Mongo see's it as two different entries on the same property.
回答2:
Reference here
Query query = new Query(
Criteria.where("ip").is(ip)
.andOperator(
Criteria.where("createdDate").lt(endDate),
Criteria.where("createdDate").gte(startDate)
)
);

You also can add query annotaion:
@Query("{'date' : { $gte: ?0, $lte: ?1 } }")
public List<AnyYourObj> getObjectByDate(Date from, Date to);
Or proper spring data method signature:
public List<AnyYourObj> findByDateBetween(Date from, Date to);
Both of these approaches give the same result.

I had to find dates between on field publishedDate
and here is how I did it:
Criteria publishedDateCriteria = Criteria
.where("publishedDateObject").gte(psDate)
.lte(peDate);
Query query = new Query(publishedDateCriteria);
mongoTemplate.find(query,
MyDocumentObject.class));
回答5:
This works on version 2.7.2 of the Java driver
DBCollection coll = db.getCollection("posts");
BasicDBObject date = new BasicDBObject();
date.append("$gte", new Date(startDate));
date.append("$lte", new Date(endDate));
DBObject query = new BasicDBObject();
query.put("date", date);
DBCursor cursor = coll.find(query);
Also, for the record you have "startDate" for both the gte and the lte parameters.
回答6:
I did like this
public interface PolicyRepository extends MongoRepository<Policy, String> {
@Query("{'lastDate':{$gt:?0,$lt:?1}}")
public List<Policy> findAllPolicies(Date today,Date somedate);
}
回答7:
It works, he is some sample code:
Criteria criteria = Criteria.where("pt").gte(startDate)
.andOperator(Criteria.where("pt").lt(endDate));
回答8:
public interface MyRepository extends MongoRepository<MyObject, MyObjectId> {
List<MyObject> findByMydatefieldBetween(DateTime startDate, DateTime endDate);
}
