    系统说明

    4.2.1 前台界面

    显示界面，其功能如下：

    • 洛阳旅游景区的信息显示：显示最近的动态的旅游景点，洛阳最近的相关新闻，等等。
    • 信息交互，可以提交一个消息函数，可以得到有关旅游景点和建议的网站系统。

    4.2.2 后台管理

    管理的背景下，其功能如下：

    • 个人信息管理：针对用户的信息和管理人员的信息可以进行维护；
    • 信息管理：上传的洛阳新闻信息，并可以删除和编辑以前的消息；
    • 景区管理：针对洛阳特色景点可以进行新增和修改或删除；
    • 留言板管理：用户信息的查看和删除管理；
    • 通过照片管理：前台页面显示点圆图；

    环境需要

    1.运行环境：最好是java jdk 1.8，我们在这个平台上运行的。其他版本理论上也可以。
    2.IDE环境：IDEA，Eclipse,Myeclipse都可以。推荐IDEA;
    3.tomcat环境：Tomcat 7.x,8.x,9.x版本均可
    4.硬件环境：windows 7/8/10 1G内存以上；或者 Mac OS； 
    5.数据库：MySql 5.7版本；
    6.是否Maven项目：否；

    技术栈

    1. 后端：Spring+SpringMVC+Mybatis
    2. 前端：JSP+CSS+JavaScript+jQuery

    使用说明

    1. 使用Navicat或者其它工具，在mysql中创建对应名称的数据库，并导入项目的sql文件；
    2. 使用IDEA/Eclipse/MyEclipse导入项目，Eclipse/MyEclipse导入时，若为maven项目请选择maven;
    若为maven项目，导入成功后请执行maven clean;maven install命令，然后运行；
    3. 将项目中springmvc-servlet.xml配置文件中的数据库配置改为自己的配置;
    4. 运行项目，在浏览器中输入http://localhost:8080/ 登录
