commons-fileupload对来自不同系统客户端文件传输的细微差别
用commons-fileupload进行文件上传，对于不同的系统有略微的差别
?
将得到的FileItem进行迭代，通过getName方式可以得到文件的文件名，但有如下问题需要注意
?
XP系统传输过来，得到的getName是全路径+文件名+后缀名，如：
C:\Documents and Settings\Administrator\My Documents\My Music\god.mp3
?
WIN7系统传输过来，得到的getName只是文件名+后缀名。如：
god.mp3
?
服务器是WIN7
?
一个小知识点，算是写下来，留个印象。

下面贴上源码
