这几天研究了一下jspwiki把网页存到硬盘上的代码,想出了一个解决的办法. jspwiki把文件名转换成%xx的格式是为了能在硬盘上存储各个国家语言的文件, 如果我们只在中文环境下使用,则没有必要进行这样的转换. jspwiki里的pageprovider和attachmentprovider负责了上面的转换, 而这两个provider可以在jspwiki.properties里面设置,所以我们继承一下 jspwiki里提供的类,再在配置文件里设置一下,很容易就让jspwiki不进行文件名转换了. 我是通过继承nativefilenameversioningfileprovider和basicattachmentprovider类实现子类的.可惜basicattachmentprovider中负责文件名转换的方法是static的,我在子类里没办法把它重载掉,这个问题已经向jspwiki的开发者提出修改意见了.现在page名可以存为中文了,附件名还要等到jspwiki的basicattachmentprovider修改了以后才能实现. 附件里是编译完的代码,把它拷贝到jspwiki的lib目录里,再在jspwiki.properties里设置 "jspwiki.pageprovider =net.sf.startemplate.nativefilenameversioningfileprovider" 就可以把page存为中文名的文件了.这个provider和已有的%xx形式的page不能正常工作, 需要把这些page的名称改成未编码的中文格式. 至于utf8编码的文件用notepad修改后会在最前面添加3个字符,那都是微软做的孽,不用微软的 或者基于微软的文本编辑器就行了.(微软为了识别unicode的编码,在文件最开始加了标识符, 而其他公司并不承认这个标准,所以才导致这些标识符会被显示出来) 浏览器对网址会转换成%xx形式后再向服务器,服务器收到以后也都有相应的逆向转换,这个应该 没有什么问题. 很高兴和你交流!! 以下是我的代码:两个provider和一个工具类 1:/** 2: * created on 2005-9-8 by dengber. 3: */ 4:package net.sf.startemplate;
