Question

Find objects between two dates MongoDB正在回答mongoshell命令。但我要求它用Java做。我已经解释了我的问题了。希望这有帮助

以下是对象

 {
    "_id" : ObjectId("5a8f997fcdc2960adae4f91a"),
    "cobDate" : ISODate("2018-02-15T18:30:00.000Z"),
    "Version" : 1
}

在MongoShell中使用的查询

db.getCollection('collection').find({"cobDate" : { "$gt" : ISODate("2018-04-04T00:00:00.000Z"), "$lte" : ISODate("2018-04-06T00:00:00.000Z")}})

以下是我的Java代码。

        String businessDate = "2018-04-05"; //This is the argument to be passed in string by user
        LocalDate sDate = LocalDate.parse(businessDate);
        LocalDate eDate = sDate.plusDays(1);
        SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
        Date ssdate = format.parse(sDate.toString());
        Date eedate = format.parse(eDate.toString());

        String startDate = MongoConnect.toISO8601UTC(ssdate);
        String endDate = MongoConnect.toISO8601UTC(eedate);

        BasicDBObject query = new BasicDBObject();
        query.put("cobDate", BasicDBObjectBuilder.start("$gt", endDate).add("$lte", endDate).get()) ; 

        db.getCollection(collectionName).find(query)

这里syso（查询）输出是 - ＆gt;

{"cobDate" : { "$gt" : "2018-04-04T00:00:00.000Z", "$lte" : "2018-04-06T00:00:00.000Z" } }

并不适合我在哪里＆＃34; cobDate＆＃34;存储如 ISODate（＆＃34; 2018-04-05T00：00：00.000Z＆＃34;

查找大于或等于您的日期且小于您的日期+ 1天的日期比尝试使用正则表达式解析文本更容易，更快。

String sourceDate = "2018-02-15";
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
Date startDate = format.parse(sourceDate);
Date endDate = DateUtil.addDays(myDate, 1);

collection.find(and(gte("Date", startDate ), lt("Date", endDate )));

使用JAVA
