如何自由组织Tapestry页面规范文件

问题的提出

默认Tapestry的页面模板文件l）及其对应的规范文件(page)可以放在web根目录或其下的WEBINF/目录中Tapestry可以不用任何配置（在以前的版本中需要在application文件中定义一下页面）就能正确运行如果你需要在这些根目录下以文件系统的目录形式组织你的页面则Tapestry是不会自动搜索这些子目录的你必须在application文件中定义这些不在默认位置的页面这样一来每加一个页面都需要定义一下如果页面数目众多定义起来就会比较麻烦如何才能避免这些配置呢？本文的目的就是尝试解决这个问题

问题的解决

本文是在参考文档（）源代码的基础上稍作修改而成主要是为了解决不能在Tomcat中使用的问题为了更好的了解朋友们最好能阅读一下原文和原来的代码主要修改的地方是给RecursiveFileLocator传递一个真实路径地址以便能够列出目录下面的子目录从而实现层次查找

解决的途径就是定义一个ISpecificationResolverDelegate以便Tapestry在常规路径下找不到文件时进行处理
