Hibernate OGM With Mongodb Count query with $gt $gte $lt $lte not working with less than 1

Question

我正在使用 Hibernate OGM (5.2.0.Alpha1) 和 Mongodb (3.4)

我执行了Mongodb Count Query Using Hibernate OGM by 2 below way

(1)。计数查询使用 Mongodb 计数查询 db.tablename.count({..})

(2)。计数查询 Mongodb 聚合查询...

说明

(1)。计数查询使用 Mongodb 计数查询 db.tablename.count({..})

public long executeCountQuery(){

    //below line Works fine because value is 1.3 with $lt
    //String query= "db.sales_stone_details.count({'$and':[{'size' : { '$lt' : 1.3}}]})" 

    //below line gots Error because value is 0.3(less than 1) with $lt
    String query= "db.sales_stone_details.count({'$and':[{'size' : { '$lt' : 0.3}}]})"   

    long count = entityManager.createNativeQuery(query.toString()).getSingleResult();
    return count;
}

(2)。计数查询 Mongodb 聚合查询...

public long executeCountQuery(){

    //below line Works fine because value is 1.3 with $lt
    //String query= "db.sales_stone_details.aggregate([{'$match': {'size': {'$lt': 1.3}}},{'$group': {'_id' :  ObjectId(\"59df0d28f16b004af040c38c\"), 'countForAggregate' : {'$sum' : 1}}}])"

    //below line gots Error because value is 0.3(less than 1) with $lt
    String query= "db.sales_stone_details.aggregate([{'$match': {'size': {'$lt': 0.3}}},{'$group': {'_id' :  ObjectId(\"59df0d28f16b004af040c38c\"), 'countForAggregate' : {'$sum' : 1}}}])"

    List<Stone> stones = entityManager.createNativeQuery(query.toString() , Stone.class).getResultList();

    long count = 0;
    if (stones != null || !stones.isEmpty()){
         count  = stones.get(0).getCountForAggregate();
    }

    return count;
}

错误

我在使用 $gt , $lte , $gte 操作符时也遇到了同样的错误。

但似乎 $gt , $gte , $lt , $lte 不适用于小于 1 的值..

我说的对吗？？？

更新 11/01/2018：此问题应在下一个版本中修复：5.2

是的，你是对的。你发现了一个错误。我已经为它创建了一个问题，它应该在下一个版本中得到修复：https://hibernate.atlassian.net/browse/OGM-1371
