后台代码 (Grails+Groovy)：
def upload={params.each{println it}CommonsMultipartFile uploadFile=params.fileif(!uploadFile.isEmpty()){String oFileName=uploadFile.getOriginalFilename()Date fname=new Date()Long fff=fname.getTime()def fileSaveName=fff+oFileName.substring(oFileName.lastIndexOf("."))def fileSavePath=request.getRealPath("/")+"uploads\"+ fileSaveNameprintln fileSavePathuploadFile.transferTo(new File(fileSavePath) )session.setAttribute("stupic",fileSaveName)render "上传成功,请关闭提示窗口！"}else{}}?如果有不会写的 请给本人留言 谢谢
