Java 实战范例之精美网上音乐平台的实现

一、项目简述

本系统功能包括： 音乐播放 用户登录注册 用户信息编辑、头像修改 歌曲、歌单搜索 歌单打分 歌单、歌曲评论 歌单列表、歌手列表分页显示 歌词同步显不 音乐收藏、下载、拖动控制、音粉制 后台对用户、歌曲、歌手、歌单信息的管理

二、项目运行

环境配置： Jdk1.8 + Tomcat8.5 + Mysql + HBuilderX (Webstorm也 行)+ Eclispe (IntelliJ IDEA,Eclispe,MyEclispe,Sts都支 持)。

项目技术： Springboot + Maven + Mybatis + Vue + Redis, B/S 模式+ Maven等等

歌手信息操作代码:

@Controller
public class SingerController {

    @Autowired
    private SingerServiceImpl singerService;

    @Configuration
