Question

我的mongoDb集合中有一些数据，字段名称 billingDate ，我将以如下的ISO格式存储结算日期。

{
"_id":"xxyy",
"name":"abcd",
"billingDate":ISODate("2018-01-03T13:50:05.000+0000"),
}

我想查询我的收藏品的日期范围，例如从一个日期到另一个日期获取所有帐单。为了实现这一点，我从用户获取日期，然后将其转换为mongoDb的匹配格式。

fromTime // value from user in format("dd/mm/yyyy")
toTime  // value from user in format("dd/mm/yyyy")

DateTimeFormatter dtf = DateTimeFormatter.ofPattern("dd/MM/yyyy");
        dtf = dtf.withLocale(Locale.US);  // Locale specifies human language for translating, and cultural norms for lowercase/uppercase and abbreviations and such. Example: Locale.US or Locale.CANADA_FRENCH
        LocalDate fdate = LocalDate.parse(fromTime, dtf);
        LocalDate tdate = LocalDate.parse(toTime, dtf);
        System.out.println("date is :: "+fdate);
        LocalDateTime flocalDateTime=LocalDateTime.of(fdate, LocalTime.MIDNIGHT);
        Instant finstant=flocalDateTime.toInstant(ZoneOffset.UTC);
        LocalDateTime tlocalDateTime=LocalDateTime.of(tdate, LocalTime.MIDNIGHT);
        Instant tinstant=tlocalDateTime.toInstant(ZoneOffset.UTC);
        System.out.println("from TIme is :: "+finstant);
        System.out.println("to time is :: "+tinstant);

现在当我向mongodb查询仅 $ gte 的数据时，它工作正常，但是当我使用 $ lte 时，它给了我错误。

        Date fdate=Date.from(finstant);
        Date tdate=Date.from(tinstant);
Query query= new Query();
        query.addCriteria(Criteria.where("queryBillDate").gte(fdate));
        query.addCriteria(Criteria.where("queryBillDate").lte(tdate));

         List<OPDBill> listOfBills = mongoTemplate.find(query, OPDBill.class,OPDBillsCollection);

错误日志如下：

SEVERE: Servlet.service() for servlet [spring-dispatcher] in context with path [/ClipCare1.0] threw exception [Request processing failed; nested exception is org.springframework.data.mongodb.InvalidMongoDbApiUsageException: Due to limitations of the com.mongodb.BasicDBObject, you can't add a second 'queryBillDate' criteria.

我已经更新了我的问题，我已将我的实例更改为日期实例，但现在它又给了我一个错误。

我看到你正在使用Spring。尝试使用MongoOperations：

Date fdate=Date.from(finstant);
Date tdate=Date.from(tinstant);

List<OPDBill> listOfBills = mongoOperations.find(
                Query.query(Criteria.where("queryBillDate").gte(fDate).lt(tDate)), 
                OPDBill.class,
                OPDBillsCollection);

使用Java查询MongoDb的日期范围
