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
