Java实战房屋租赁网的实现流程
作者：qq_1334611189
读万卷书不如行万里路，只学书上的理论是远远不够的，只有在实战中才能获得能力的提升，本篇文章手把手带你用java+SSM+jsp+mysql+maven实现一个房屋租赁网站,大家可以在过程中查缺补漏，提升水平
一、项目简述
功能包括： 前台:系统首页，酒店介绍，系统公告，客房信息，客房类型，用 户预等等。 用户:注册登陆修改我的信息客房预订等等。 管理员修改登录密码，添加客房,会员信息管理等等。
二、项目运行
环境配置： Jdk1.8 + Tomcat8.5 + mysql + Eclispe (IntelliJ IDEA,Eclispe,MyEclispe,Sts 都支持)
项目技术： JSP +Spring + SpringMVC + MyBatis + html+ css + JavaScript + JQuery + Ajax + layui+ maven等等。
