问题描述
首先,我的问题是通过Spring JPA(MongoRepository)在MongoDB中搜索集合.
First of all, my issue is searching Collecttions in MongoDB via Spring JPA (MongoRepository).
我的对象:
{
"_id" : ObjectId("5c78e1f447f39c2eacb229d7"),
"lab" : "xxx",
"type" : "Holiday",
"description" : "Lunar New Year",
"start_date" : ISODate("2019-02-04T02:37:42.152Z"),
"end_date" : ISODate("2019-02-08T06:37:42.152Z"),
"all_day" : true,
"_class" : "xxx.Event"
}
我可以在Mongo查询中按我的意愿做
i can do as my wish in Mongo query as:
db.getCollection('event').find({"start_date" : {$gte :ISODate( "2019-02-03T02:37:42.152Z") , $lte :ISODate( "2019-02-08T02:37:42.152Z")}})
(您可以将ISODate替换为新的日期)
(you can replace ISODate with new Date)
但是要在春季做到这一点,我想这样做:
But to do it in Spring, i want to do it as:
@Query(" $or: [ {start_date : {$gte :ISODate( ?0 ) , $lte :ISODate( ?1)}} , {end_date : {$gte :ISODate( ?0) , $lte :ISODate( ?1)}} ] } ")
List<Event> findAllEventByTime(String from, String to);
But it fail, i searched in two topic:hereand there
并以
@Query("{ 'start_date' : {$gte : {'$date': '?0'}, $lte :{'$date': '?1'} }}")
List<Event> findAllEventByTime(String from, String to);
但是再次,我在解析时遇到了问题:
But once again, i had the problem with parsing:
org.bson.json.JsonParseException:无法将字符串作为日期解析为 org.bson.json.JsonReader.visitDateTimeExtendedJson(JsonReader.java:1057)
org.bson.json.JsonParseException: Failed to parse string as a date at org.bson.json.JsonReader.visitDateTimeExtendedJson(JsonReader.java:1057)
我尝试以下建议:
尝试参数:3月22日星期五10:09:48 ICT 2019和2019-03-22T03:09:48.227Z和2016-04-14 00:00:00
Try param: Fri Mar 22 10:09:48 ICT 2019 and 2019-03-22T03:09:48.227Z and 2016-04-14 00:00:00
所有这些都消失了...你们可以帮我解决这个问题吗?
All of this going down...Can you guys help me to fix it?
工作流:来自FE(字符串)的参数〜>转到BE〜>如上所述调用回购
Work-Flow: Params from FE (String) ~> Go to BE ~> Call Repo as above
推荐答案
我用其他方法解决该问题:
I resolve it with other method:
- 在存储库中
- 我无法使用原始查询或任何需要从String转换为Date的查询进行转换
- 使用MongoRepository的自动生成查询支持
- In repository
- I can't convert with raw query or any query that need to convert from String to Date
- Use the auto generate query support by MongoRepository
Page<Event> findAllByStartDateBetweenOrEndDateBetween(Instant fromDate1, Instant toDate1, Instant fromDate2, Instant toDate2, Pageable pageable);
List<Event> findAllByStartDateBetweenOrEndDateBetween(Instant fromDate1, Instant toDate1, Instant fromDate2, Instant toDate2);
- 输入数据:使用Instant或LocalDate/LocalDateTime并将其转换为Instant〜>然后在查询中用作参数(由Spring自动转换)
- Input Data:Use Instant or LocalDate / LocalDateTime and convert it to Instant~> Then use as param in query (auto convert by Spring)
@RequestParam Instant startDate, @RequestParam Instant endDate
并使用:
eventRepository.findAllByStartDateBetweenOrEndDateBetween(startDate, endDate, startDate, endDate))
