Java图书管理系统，java课程实习

前序

运行环境：Eclipse，SQL Server
完整zip下载链接：http://download.csdn.net/download/android_tools/10186799
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。
