本篇主要介绍了Java开发入门到实战--Java项目实操训练：酒店预定管理系统(java+JDBC+jsp+servlet+Mysql)，通过具体的内容展现，希望对Java开发的学习有一定的帮助。
jsp+servlet+mysql实现的酒店管理系统，后台没有用到框架，用的是基础的servlet，前端用了一个仿win10的界面模板和layui前端框架，界面非常漂亮大气。
主要实现的功能有：管理员登录、楼层管理、房型管理、房间管理、预定管理、入住管理、查看账单、日志管理、用户管理等，所有管理列表页面都提供了导出到excel的功能。
酒店信息控制层：
/**

@Controller
@RequestMapping("/hotels")
