bookstore.util.EncodingFilter.doFilter(EncodingFilter.java:26)这是错误的代码：bookstore.database.Userinfo user = (bookstore.database.Userinfo) session.getAttribute("user");
org.hibernate.Session dbSession = bookstore.database.HibernateUtil.currentSession();
bookstore.database.HibernateUtil.beginTransaction();
org.hibernate.Query query = dbSession.createQuery(" from Bookinfo as b where b.remaining >0 order by b.id asc");
query.setMaxResults(3);
java.util.List result = query.list();
bookstore.database.HibernateUtil.commitTransaction();
request.setAttribute("books", result);
request.setAttribute("newest", result.get(0));
bookstore.database.HibernateUtil.beginTransaction();
query = dbSession.createQuery("from Order as o where o.userinfo=:userinfo order by o.id desc");
query.setParameter("userinfo", user);
query.setMaxResults(4);
result = query.list();
bookstore.database.HibernateUtil.commitTransaction();
request.setAttribute("orders", result);
但是问题是不是出在.hbm.xml文件中 啊
