Flex版Mp3播放器----大部分功能版一，前台

利用假期学习了下flex，个人感觉要做点啥东西才能算的上熟练，恰逢工作室让写一个听歌的程序，自己就尝试写了个，菜鸟作品，多多批评。

 

首先 给个预览看下

 

登录页面：（javaeye的加入图片太麻烦了 要看的同志们到这里看：http://user.qzone.qq.com/361276898 里面听听那个相册就可以看了）

 

总体将：采用 Hibernate + Spring + flex + Blades（忘了单词咋写的 ^_^） 

 

一，前台的代码 newting.mxml

关于以上的  有些函数没有用到在应用中，主要是自己还没那水平，希望以后能补上 .

 

二，配置和后台交互相关的
