Question

我尝试使用mongorepository或mongooperations或mongotemplate从mongodb获取今天创建的所有记录。我希望按日期匹配所有记录，而不是在时间戳上。请参考下面我的mongodb enteries。

/* 1 */
{
"_id" : ObjectId("59135f13fc90f22b00c91df2"),
"_class" : "com.vistors.management.domains.EmployeeVisitor",
"checkedIn" : true,
"checkedInDate" : ISODate("2017-05-10T18:42:27.630Z"),
"visitor" : {
    "$ref" : "VISITOR",
    "$id" : ObjectId("59135f13fc90f22b00c91def")
},
"employee" : {
    "$ref" : "EMPLOYEE",
    "$id" : ObjectId("59135f13fc90f22b00c91df0")
}
}

/* 2 */
{
"_id" : ObjectId("59135f13fc90f22b00c91df3"),
"_class" : "com.vistors.management.domains.EmployeeVisitor",
"checkedIn" : true,
"checkedInDate" : ISODate("2017-05-10T18:42:27.638Z"),
"visitor" : {
    "$ref" : "VISITOR",
    "$id" : ObjectId("59135f13fc90f22b00c91dee")
},
"employee" : {
    "$ref" : "EMPLOYEE",
    "$id" : ObjectId("59135f13fc90f22b00c91df0")
}
}

/* 3 */
{
"_id" : ObjectId("5913ec9eafeb7a1e8df79d5f"),
"_class" : "com.vistors.management.domains.EmployeeVisitor",
"checkedIn" : true,
"checkedInDate" : ISODate("2017-05-11T04:46:22.425Z"),
"visitor" : {
    "$ref" : "VISITOR",
    "$id" : ObjectId("59135f13fc90f22b00c91dee")
},
"employee" : {
    "$ref" : "EMPLOYEE",
    "$id" : ObjectId("59135f13fc90f22b00c91df0")
}
}

我想从db中获取与checkInDate匹配的所有enteries作为今天的日期：

@Query("{'checkedInDate': {$gte: ?0, $lte:?0 }}")
List<EmployeeVisitor> findAllCheckedInToday(ZonedDateTime date)

或

@Override
public List<EmployeeVisitor> getTodayRecords() {

//Date date = Date.from(instant);

    Query query = new Query().addCriteria(Criteria.where("checkedInDate").is(new Date()));
    return mongoTemplate.find(query, EmployeeVisitor.class);

    //Criteria.where("expenseDate").gte(calendar1.getTime()).lte(calendar2.getTime()).and("userid").is(uid);}
}

但是我未能达到要求的结果，我无法理解如何从数据库中查询日期而不是带时间戳的日期。

感谢您的帮助。

Answer 1

继续@Veeram的建议。这就是你能做的，

ZonedDateTime today = ZonedDateTime.of(LocalDate.now(), LocalTime.MIDNIGHT, ZoneId.systemDefault());
ZonedDateTime tomorrow = today.plusDays(1);  
repository.finByCheckedInDateBetween(Date.from(today.toInstant()), Date.from(tomorrow.toInstant()));

您可以将存储库方法更改为此类

finByCheckedInDateBetween(Date from, Date to)

Answer 2

您可以将存储库方法更改为以下形式：

List<EmployeeVisitor> findByCheckedInDate(ZonedDateTime date)

今天使用Spring数据查找mongorepository或Mongooperations中的@Query或mongotemplate
