数据库链接工具：navcat,小海豚等
技术：ssm
摘 要
随着移动互联网时代的发展，网络的使用越来越普及，用户在获取和存储信息方面也会有激动人心的时刻。音乐也将慢慢融入人们的生活中。影响和改变我们的生活。随着当今各种流行音乐的流行，人们在日常生活中经常会用到的就是在线云音乐系统。
本文首先分析了基于JSP的在线云音乐系统需求，并从系统开发环境、系统目标、设计流程、功能设计等方面对系统进行了系统的设计。基于JSP的音乐播放器应用程序是用java语言设计。客户端主要实现在线云音乐系统，根据需要选择最喜爱的音乐，并推荐歌曲、收藏喜欢的歌曲，查看歌曲信息等主要功能模块，实现在线云音乐系统的系统功能。通过对系统功能的测试，测试结果表明该系统界面友好，功能齐全，具有很高的使用价值，具有巨大的潜在用户群和广阔的应用前景。
