@PathParam和@QueryParam有什么区别？(What is the difference between @PathParam and @QueryParam)

 如果您正在讨论文档中数组中的“索引”位置，那么您需要$slice运算符。 第一个参数是开始的索引，第二个参数是返回的数量。 所以从0指数位置2是“第三”指数： 
 
 db.collection.find({},{ "list": { "$slice": [ 2, 8 ] })
 
 如果使用.limit()和.skip()修饰符来移动集合中的范围，则在集合本身内： 
 
db.collection.find({}).skip(2).limit(8)
 
 请记住，在集合上下文中，MongoDB没有“有序”记录的概念，并且依赖于给定的查询和/或排序顺序 

If you are talking about the "index" position within an array in your document then you want the $slice operator. The first argument being the index to start with and the second is how many to return. So from a 0 index position 2 is the "third" index:
 
 db.collection.find({},{ "list": { "$slice": [ 2, 8 ] })
 
Within a collection itself if you use the .limit() an .skip() modifiers to move through the range in the collection:
 
db.collection.find({}).skip(2).limit(8)
 
Keep in mind that in the collection context MongoDB has no concept of "ordered" records and is dependent on the query and/or sort order that is given
