下面是Spring模型类，如下所示，我使用Spring数据模块来保存attachment集合中的文档
@Document(collection = "attachment")
class Attachment {
@Id
private String id
private String fileName, attachment
private Calendar createdAt, updatedAt
}
以下是mongo db（createdAt）中version 3.4.14的值
我不确定如何在mongo中查询java日历实例，createdAt值大于2018-01-01T00:00:00.000Z，有人可以帮助我吗？
