if(imageType[ii].equals(type)) { if(!singlefile.isMissing()){ String photoTime = su.getRequest().getParameter(\ String photoDescription = su.getRequest().getParameter(\ photoForm.setPhotoTime(photoTime);

photoForm.setUser_id(Integer.parseInt(su.getRequest().getParameter(\)); photoForm.setPhotoDescription(photoDescription); filedir = filedir + maxID + \+ singlefile.getFileExt(); photoForm.setPhotoAddress(filedir); if(photoDao.operationPhoto(\添加\

singlefile.saveAs(filedir,File.SAVEAS_VIRTUAL); result = \上传照片成功！\ } } } } } }catch(Exception e) { e.printStackTrace(); }
