//文件上傳后，保存在c:\\upload
String saveDirectory ="c:\\upload";
//每個文件最大5m,最多3個文件,所以
int maxPostSize =3 * 5 * 1024 * 1024 ;
//response的編碼為"gb2312",同時采用缺省的文件名沖突解決策略,實現(xiàn)上傳
//就這一句就完成上傳了,真是很爽
MultipartRequest multi = new MultipartRequest(request, saveDirectory, maxPostSize,"gb2312");
//輸出反饋信息
Enumeration files = multi.getFileNames();
