项目介绍
管理员角色包含以下功能：
管理员登陆,用户管理,新闻管理,留言列表查看等功能。
用户角色包含以下功能：
查看所有新闻,市场资讯查看,科技推广查看,致富经栏目查看,网站留言,用户注册登陆等功能。
由于本程序规模不大，可供课程设计，毕业设计学习演示之用
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；
技术栈
1. 后端：Spring+SpringMVC+Mybatis
2. 前端：HTML+CSS+JavaScript+jsp
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application.yml配置文件中的数据库配置改为自己的配置;
4. 运行项目，输入localhost:8080/ 登录
