我有上千个记录,需要用一个用户点击来检索。目前,它给我的结果非常缓慢,我必须等待很长时间。是否有办法用冬眠来改进这些结果的检索?
我有一个案例, 一个有选择查询的方法 将每分钟运行一次。 这是Hibernate给我的慢结果。 我使用与 MySQL 的休眠 。
通常的做法是启用二级缓存和查询缓存。 您的数据不会从 db 中读取, 而不是从记忆中读取 。

其他事情可以有所帮助:
1 索引化 - 如果有位置和顺序, 您需要为您正在搜索/ 排序的字段建立索引 - 这样可以提高搜索速度10 次
2 非正规化――如果你有很多人加入的话, 某些非正规化(将全部列在单张表格中)可以起到帮助作用。 但是,当其他一切失败时,这应该是最终的解决办法。
我建议你使用Puginating ,如果你必须在网页上显示记录并同时检索部分记录(100)的话。
