问题补充：
/** *用户加入购物车，确定购买生成了，订单表，和订单细节表 * */ //1.通过登陆获得user实体 List<Users> list=session.createQuery("from Users u where u.loginName=?and u.loginPwd=?") .setString(0, "zyw") .setString(1,"123456").list(); System.out.println(list.get(0).getEmail()); List<Book> blist=session.createQuery("from Book u where u.id='1'").list(); Orders neworder=new Orders(); neworder.setUsers(list.get(0)); neworder.setOrderTime(new Date()); neworder.setOrderPrice((float)30.0); Orderdts newdts=new Orderdts(neworder, blist.get(0), neworder.getOrderPrice(), 3); Set set=new HashSet<Orderdts>(); set.add(neworder); neworder.setOrderdtses(set); // Transaction tx=session.beginTransaction(); // session.save(newdts); // session.save(neworder); // tx.commit();
注释掉session.save();就没错，我的订单表和细节表save就报错
