Struts1.2实现动态多文件(不定个数)上传
/**

????????fileupload.setFilename(basePath?+?"/main/upload/"?+?file.getFileName());

????????//扩展名处理
????????if?("jpg".equals(ext.toLowerCase())?||?"bmp".equals(ext.toLowerCase())

????????{
????????????ext?=?"img";
????????}
????????if?("rar".equals(ext.toLowerCase())?||?"zip".equals(ext.toLowerCase())
????????????????||?"jar".equals(ext.toLowerCase()))
????????{
????????????ext?=?"rar";
????????}
????????if("txt".equals(ext.toLowerCase())?||?"sql".equals(ext.toLowerCase())?||?"ini".equals(ext.toLowerCase()))
????????{
????????????ext?=?"txt";
????????}
????????fileupload.setFileext(ext);
????????fileupload.setFilesize(file.getFileSize());
????????fileupload.setUptime(new?Date());
????????fileupload.setDowncount(0);
????????fileupload.setUpuser(((User)?request.getSession().getAttribute("user"))
????????????????.getUserName());
????????fileupload.setFlag((short)?0);
????????fileupload.setAnnounceId(bbs.getAnnounceId());
????????fileupload.setName(file.getFileName());
????????fileuploadManager.save(fileupload);
????????log.info("BbsAction:附件信息已经成功保存到数据库");
????}
这样就实现的动态的多文件上传.关键还是
的处理.
其中的数据库操作部分不是必须的.
