Java lucene Apache 音乐百度

小弟马上就要毕业了，感觉这段时间比较闲的！就利用这段时间好好锻炼锻炼一下！于是就决定做个博客系统！经过差不多一个月的时间，终于搞定！拿上来让同行们给点意见！系统主要利用s2sh+lucene+oracle技术进行开发！

首先声明一下：小弟不是为了别的，只是想让大家多提点意见，比如代码方面啊，等等！好了不说那么多了！
注意：由于小弟的美工不太好，小弟的这个博客系统模仿了网上某位大侠博客系统的页面美工！
声明：由于接下来小弟忙于别的事情，所以没有对项目代码进行优化，所以有很多重复性代码！所以我认为代码确实存在很多缺点！

下面图片是主页的截图

下面图片是日志模块的截图

下图是留言模块的截图(留言模块利用到struts2+json+jquery实现ajax异步技术实现)

下图是图片显示的截图模块( 主页是利用thickbox实现浏览相片功能，和利用纯js实现防百度的相册和ajax评论)

防百度显示相册功能：

下图是音乐播放模块（这个模块主要防网易的音乐播放模块）

音乐播放是调用网易的音乐播放器

下图是利用lucene搜索日志高亮显示模块（主要是利用lucene技术进行实现的高亮显示和搜索）

文章显示模块：（相关文章提示主要是利用lucene对题目进行分词，在进行对索引进行查询）

程序下载模块：（这个模块主要是上传项目供用户下载）

后台模块
登陆界面：

日志添加：（主要利用fckeditor编辑器实现）

就贴这么多了！

代码总体结构如下.

贴上部分代码：（lucene索引的建立和查询）
