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
