系统说明

4.2 系统功能

4.2.1 登录与注册功能

系统的登录分为了前台登录和后台登录两个模块，都分别处在不同的界面上的，共同的特点就是用户分别键入用户名密码后提交给系统进行处理，如果登录成功后即可跳转界面，登录不通过的话就会进行错误提示。

4.2.2 新闻公告功能

系统需要有新闻公告的查看以及后台的管理功能主要是为了提供给系统前台用户以音乐咨询的查询，这样可以使得系统更加专业化，信息更加全面化而不是单一的音乐播放这一功能。

4.2.3 音乐分类功能

一个音乐点歌网站是拥有成千上万的音乐单曲的，如果不提供分类功能的话对于没有选择性的用户来说如何对这么多的音乐进行选择是一件十分痛苦的事情。

4.2.4 音乐在线播放功能

系统既然是web系统就需要提供音乐的在线播放功能而不是仅仅提供音乐的下载，一个是方便了用户在线的音乐收听还可以留住用户在系统上的使用时间。

4.2.5 留言管理功能

系统的前台需要有留言功能是非常关键的，通过系统用户的在线交流可以增加用户之间的互动性让系统用户更加对系统进行依赖和喜爱。

4.3系统数据库设计

数据库是本系统的核心和基础。数据库设计将直接决定一个程序的好坏，是一个非常重要的环节，如果把一个项目比喻为一栋建筑，那么数据库就是这栋建筑的地基，地基好坏将直接决定这栋楼的稳固性，所以在早期设计数据库的时候就要多方面、多角度思考，甚至要考虑到后期维护。

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
