SmartUpload smartupload = new SmartUpload();
smartupload.initialize(this.getServletConfig(),request,response);
String imagename = null;
String iname = null;
//准备上传
try {
说这行报错//smartupload.upload() ;
IPTimeStamp ip = new IPTimeStamp();
iname = ip.getIPTimeStampRand()+"."+smartupload.getFiles().getFile(0).getFileExt();
imagename = this.getServletContext().getRealPath("/")+"admin/"+iname;
smartupload.getFiles().getFile(0).saveAs(imagename) ;
} catch (SmartUploadException e) {
e.printStackTrace();
}
