My document structure in Mongo is like this :
db.user.find()
{
"_id" : ObjectId("560fa46930a8e74be720009a"),
"createdAt" : ISODate("2015-10-03T09:47:56.333Z"),
"message" : "welcome",
}
{
"_id" : ObjectId("560fa46930a8e723e720009a"),
"createdAt" : ISODate("2015-10-03T09:48:25.048Z"),
"message" : "thank you"
}
When I use the below query in my Mongo Shell to find documents between two given timestamps, i get the right result :
db.user.find({createdAt:{$gte:ISODate("2015-10-03T09:40:25.048Z"),$lte:ISODate("2015-10-03T09:50:56.333Z")}})
I am using MongoRepository with Spring in my REST service to work with the Java driver. Below is the user repository:
public interface UserRepository extends MongoRepository<User, String>
{
ArrayList<User> findbyCreatedAtBetween(Date d1, Date d2);
}
When I call make the following call in my service, it does not return any result
userRepository.findbyCreatedAtBetween(2015-10-03T09:40:25.048Z, 2015-10-03T09:50:29.006Z)
However it returns the result when I give d1 as previous day : userRepository.findbyCreatedAtBetween(2015-10-02T09:40:25.048Z, 2015-10-03T09:50:29.006Z)
Any ideas on how I can resolve this? Please help!
Breaking it down, the query with the keyword Between
is being executed against the MongoDB database with the logical result {"createdAt" : {"$gt" : d1, "$lt" : d2}}
so there is a chance that you are not getting the documents that have the createdAt
date inclusive within the given date range i.e. d1 < createdAt < d2
since the given date range does not satisfy the criteria. For reference these are some of the interpretations on the query methods:
Supported keywords for query methods
Keyword Sample Logical result
After findByBirthdateAfter(Date date) {"birthdate" : {"$gt" : date}}
Before findByBirthdateBefore(Date date) {"birthdate" : {"$lt" : date}}
Between findByAgeBetween(int from, int to) {"age" : {"$gt" : from, "$lt" : to}}
As a workaround, you may want to use the @Query
annotation. I haven't tested this but you may want to try the following custom query implementation example:
public interface UserRepository extends MongoRepository<User, String> {
@Query(value = "{ 'createdAt' : {$gte : ?0, $lte: ?1 }}")
public ArrayList<User> findbyCreatedAtBetween(Date from, Date to);
}
If the above doesn't work for you, create a custom interface and your implementation class to execute the custom query. For example, create an interface with a name that appends Custom
:
public interface UserRepositoryCustom {
public List<User> findbyCreatedAtBetween(Date from, Date to);
}
Modify the UserRepository
and add the UserRepositoryCustom
interface to be extended:
@Repository
public interface UserRepository extends UserRepositoryCustom, MongoRepository {
}
Create your implementation class to implement the methods defined in UserRepositoryCustom
interface.
public class UserRepositoryImpl implements UserRepositoryCustom {
@Autowired
MongoTemplate mongoTemplate;
@Override
public ArrayList<User> findbyCreatedAtBetween(Date from, Date to) {
return mongoTemplate.find(
Query.addCriteria(Criteria.where("createdAt").gte(from).lte(to));
}
}
