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）

如果有需要的就直接部署就可以用了！
最后附上项目代码，因为所有的jar包都在里面,还用图片比较大 ，我没有好好的优化过 ，所以目前容量比较大！
