• 项目简介

    本项目基于SSM框架开发实现了一个旅游管理平台，主要包含管理员和前端用户两种身份。前端用户注册登陆后可以进行旅游景点和酒店信息的查看，在线评论，参与论坛讨论，并对个人信息和发表的贴子进行管理。管理员主要对基础数据进行管理，用户管理，旅游景点管理，酒店管理，评论管理，论坛管理等功能。

二，环境介绍

语言环境：Java:  jdk1.8

数据库：Mysql: mysql5.7

应用服务器：Tomcat:  tomcat8.5.31

开发工具：IDEA或eclipse

后台开发技术：SSM框架

前端开发技术：Bootstrap+Ajax+Jquery

三，系统展示

 注册

登陆

评论与回复

论坛功能

后台用户登陆

用户管理

景点管理

酒店管理

论坛管理

评论管理

交通管理

四，核心代码展示
