public interface PersonDao extends MongoRepository<Person, ObjectId> {

    @Query(value = "{'age' : {'$gte' : ?0, '$lte' : ?1}, 'name':?2 }",fields="{ 'name' : 1, 'age' : 1}")
    List<Person> findByAge(int age1, int age2, String name);

}

2. use mongoTemplate

@Repository("personMongoImpl")
public class PersonMongoImpl implements PersonMongoDao {

    @Resource
    private MongoTemplate mongoTemplate;

    @Override
    public List<Person> findAll() {
        return mongoTemplate.findAll(Person.class,"person");
    }

    @Override
    public void insertPerson(Person person) {
        mongoTemplate.insert(person,"person");
    }

    @Override
    public void removePerson(String userName) {
        mongoTemplate.remove(Query.query(Criteria.where("name").is(userName)),"person");
    }

    @Override
    public void updatePerson() {
        mongoTemplate.updateMulti(Query.query(Criteria.where("age").gt(3).lte(5)), Update.update("age",3),"person");
    }

    @Override
    public List<Person> findForRequery(String userName) {
        return mongoTemplate.find(Query.query(Criteria.where("name").is(userName)),Person.class);
    }
}
