I am working on developing a paging solution using Hibernate as persistance layer and Struts2 as UI. 我正在开发使用Hibernate作为持久层和Struts2作为UI的分页解决方案。 I was following the thread Similar Thread at SO 我在SO关注线程类似线程

and it seems that the answers are themself good and explanatory,i still have some query,since i can have maximum of 2-3000 records (assuming 1-2K) so its still good approach to fetch all sorted records from db and place them in a cache and impliment paging functionality on the cache records or should be something like fetch few hundered records only. 而且似乎答案本身是好的并且可以解释，我仍然有一些疑问，因为我最多可以拥有2-3000条记录（假设为1-2K），因此从db中提取所有已排序的记录并将其放在其中仍然是一种很好的方法。缓存记录上的缓存和隐式分页功能，或者应类似于仅获取一些混乱记录。 we want paging functionality what SO have so i have already my logic to impliment this,only concern is should i fetch records from DB per page request or go for some other approach. 我们想要分页功能，所以我已经有我的逻辑可以暗示这一点，唯一需要注意的是我应该按每个页面请求从数据库中获取记录还是采用其他方法。

as a note this paging functionalty is for backend management. 注意，此分页功能用于后端管理。

Thanks in advance 提前致谢
