1.首先一个区别
script\generate scaffold product title:string description:text image_url:string
在书中
只需要添加scaffold :product到AdminController到即可实现基本的操作。2.0中删除了动态scaffold方式。
这个问题在另一篇文章里已经写了。更准确的介绍可以查看

开始为系统加入全文检索功能。考虑使用Hibernate Search 实现。
2.4节 Reader strategy 顺便翻译一些
当之行一个查询，Hibernate Search将通过一种读策略与lucene索引文件交互。选择哪种读策略取决于应用的属性(例如更新频率，主要以读为主，异步索引更新等)。可以参考3.5节读策略配置。
1.Shared
使用此策略。Hibernate Search 将使用相同的IndexReader,访问多个查询，and threads provided that the IndexReader is still up-to-date，If the Inde ...
