// 修改，LinkDAO是Myeclipse自动生成的
int id = Integer.parseInt(request.getParameter("id"));
LinkDAO dao = new LinkDAO();
Link link = dao.findById(id);
int index = Integer.parseInt(request.getParameter("index"));
String title= request.getParameter("title");
String url = request.getParameter("url");
String logo = request.getParameter("logo");
link.setIndex(index);
link.setTitle(title);
link.setUrl(url);
link.setLogo(logo);
Transaction tx = dao.getSession().beginTransaction();
dao.attachDirty(link);
tx.commit();
dao.getSession().close();
在tx.commit()的时候报错
------解决方案--------------------
你最好先把link里的属性值打印出来，看看是不是你所需要的值，然后把值跟配置文件里的字段描述再对一遍，看看是否符合要求，最后你再看看你所插入的值是否与数据库表字段的限制相冲突
