If you've used JpaRepository then it's easy to relate that you can create an interface and extends MongoRepository just like with JpaRepository and it provides some simple method, and you don't need the implement it.

you can use (for example consider A Person with First and Last name)

MongoDB JSON based query methods and field restriction

public interface PersonRepository extends MongoRepository

@Query(value="{ 'firstname' : ?0 }", fields="{ 'firstname' : 1, 'lastname' : 1}")
List findByThePersonsFirstname(String firstname);
}

Geo-spatial repository queries

public interface PersonRepository extends MongoRepository

  // { 'location' : { '$near' : [point.x, point.y], '$maxDistance' : distance}}
  List findByLocationNear(Point location, Distance distance);
}
