【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> JFinal 波总和我在谈谈我对 JFinal Marketing 的一些看法博文的评论中谈到了数学和软件之间的关系. 这篇文章中我再详细说说我的理解. 在我看来, 纵观人类知识的积累, 大致可以分为 "道" 与 "术". 所谓"道", 即天道, 也就是自然规律. 而"术", 即技术, 是人类对已发现自然规律的应用. 自先秦而降中国文化即重道而轻术, 这当然尤其历史局限, 但道在术先也是毋庸置疑的. 波总在 JFinal 4.8 发布新闻中引用了欧拉恒等式: 在我看来欧拉恒等式属于"道"的范畴, 它简洁优美地表达了几个基本量之间的关系, 这是我们这个宇宙的自然规律, 是被发现的, 而不是被发明的. 波总在对我的回复中讲到: 就因为要素 + 关系是很普适很好用的建模因子，所以才会像你所说的与很多东西存在同构。这里的关键、难点在于：你将什么东西提取并抽象成为要素与关系，一百个人可以有一百种提取方式。数学大师欧拉提取了e、i、pi、0、1、+、= 这五个要素与两个关系，请问为什么不是另一个普通人提取出来，就因为这个提取过程极难、极难，需要对本质有深刻洞察。提取抽象出要素与关系只是建模的第一步，你得验证要素与关系之间是不是逻辑自洽、续洽、他洽，否则你建立的这个模型就是错误的。光是这一步就是极难的事情。好了

问题 I know that this has been discussed lot of times. I just can't understand how this work or where my mistake is. I think giving you a reduced example is the best way to show you what I'm trying to do and what assumptions I'm taking... I have a Product class with a name. The name is a String property that is lazy. My DAO: public abstract class HibernateProductDAO extends HibernateDaoSupport implements ProductDAO { public List getAll() { return this.getHibernateTemplate().find("from " + this
