ObjectId 返回与对象标识符的时间戳对应的日期。 时间戳 返回与时间戳相对应的日期。 下表列出了转换为日期的部分示例: 例子 结果 {$toDate: 120000000000.5} ISODate("1973-10-20T21:20:00Z") {$toDate: NumberDecimal("1253372036000.50")} ISODate("2009-09-19
publicObjectId(Date time) {this(time, _genmachine, _nextInc.getAndIncrement()); } 使用Dto 实体根据创建日期范围查询,亲测有效 if(order.getCreateEndDate() !=null&& order.getCreateDate() !=null) query.addCriteria(where("objectId").gte(newObjectId(LocalDateTimeUtil.LocalDateTimeToUdate(order.ge...
