'executedDate' 是 mongodb 中字符串格式的字段，我需要通过使用 @Query(value="") 将字符串格式解析为日期格式来获取 2 个执行日期之间的记录

我已经在控制台中执行了 mongodb 查询，如下所示：

db.testExecution.aggregate( [ { $project: { date: { $dateFromString: { dateString: '$executionDate' } } } }, { $match: { date: { $lt: ISODate("2019-10-16T06: 35:03Z") } } } , { $match: { date: { $gt: ISODate("2019-09-16T06:55:03Z") } } } ] )

输出：

{ "_id" : ObjectId("5d7f8627ea9c671b877d554f"), "date" : ISODate("2019-09-16T06:55:10Z") }
{ "_id" : ObjectId("5d7f8627ea9c671b877d503f"), "date" : ISODate("2019-10-16T06:25:03Z") }
{ "_id" : ObjectId("5d7f8627ea9c671b877d502f"), "date" : ISODate("2019-09-16T10:55:55Z") }

我需要用 mongoRepository 查询格式写这个，

当我这样写查询时，

@Query(value = "{$project: {date: {$dateFromString: {dateString: '$executionDate'}}}}, {$match: {date: {$lt: ?0)}}} , {$match: {date: {$gt: ?1)}}}")
    List<TestResultResponseDomain> findByExecutionDate(Date from, Date to);

我收到如下错误。

嗨聚合不能使用@QuerySpring-data-mongoDB 中的注释来完成。您必须编写存储库类的自定义实现，然后使用具体类编写聚合。您可以使用以下链接了解如何操作。
