如果没有C币的话可以联系我哈~：qq1403528138

里面包括project文件 sql server 数据库文件 皮肤包

皮肤包使用：beautyeye_inf 是其中的皮肤包，下载后lib里添加依赖，运行主函数里写入

try{
org.jb2011.lnf.beautyeye.BeautyEyeLNFHelper.launchBeautyEyeLNF();
}
catch(Exception e){
//TODO exception
}
//这里写你的代码

在此感谢JackJiang 大神提供的皮肤包。

正文

代码片太多，建议下载完整project体会使用

主要功能：管理员登陆，读者模式，图书借还，图书管理，用户管理。

里面包括图书—用户的搜索、添加、修改、删除。
