照着上面的例子做了，怎么不能用啊。
错误如下：

请高手指点一二。。不胜感激。。
自己乱试，出来了：原来就是和原来没啥变化。。就记得把Cat.hbm.xml变成嵌入的资源。。
之前把Web.config里的 <mapping assembly="QuickStart" /> 去掉了，在程序里加的Cfg.addAssembly("QuickStart")这样做总报上面的错误，在跟踪程序里发现IDictionary properties里只有一个"True"值，是Nhibernate没有加入配置原因。还在努力学习中。
感觉这个类库提供的Mapping在面向对象开发中，还是不错的，从对象到数据库设计，这样的思路应该可以让程序员不在把大部分精力来接SQL，而是转到业务上来。
学习Ing...
