三、核心源码:

//改签
    @RequestMapping("/change/{oid}")
    public String change(@PathVariable("oid")int oid,HttpServletRequest request){
        CarTrainOrder selectFkOrder = carSerivce.selectFkOrder(oid);
        request.setAttribute("car", selectFkOrder);
        return "../change.jsp";
    }
    //改签查票
    @RequestMapping(value="/changeSearch",produces={"application/json;charset=utf-8"})
    @ResponseBody
    public String changeSearch(Carinfo car,HttpServletRequest request){
        //获取当前时间
        /*Calendar now=Calendar.getInstance();
        String now_hour=now.get(Calendar.HOUR_OF_DAY)+"";
        String now_minute=now.get(Calendar.MINUTE)+"";
        car.setStart_time(now_hour+":"+now_minute);*/
        List<CarTrain> list = carSerivce.findByProperty2(car);
        System.out.println(list.size());
        return JSONArray.fromObject(list).toString();
        
    }
    
    //点击改签查询列车信息
    @RequestMapping("/changeYd/{cid}/{oid}")
    public String changeYd(@PathVariable("cid")int cid,@PathVariable("oid")int oid,HttpServletRequest request){
        Orderinfo order = carSerivce.findOrderByOid(oid);
        CarTrain car = carSerivce.findByCid(cid);
        request.setAttribute("order", order);
        request.setAttribute("car", car);
        return "../../changeYdOrder.jsp";
    }
    
    //改签提交订单  修改列车信息
    @RequestMapping(value="/updateOrder",produces={"application/json;charset=utf-8"})
    @ResponseBody
    public String updateOrder(Orderinfo order,HttpServletRequest request){
        //获取订单提交时间
        Date date=new Date();
        SimpleDateFormat format=new SimpleDateFormat("yyyy-MM-dd");
        String d = format.format(date);
        
        order.setOdate(d);
        order.setState("3");//已改签
        
        //通过id查询订单
        Orderinfo beforeOrder = carSerivce.findOrderByOid(order.getOid());
        //原来的座位数要加一
        carSerivce.addSeatnum(beforeOrder.getCid());
        
        carSerivce.updateChangeOrder(order);
        int i=carSerivce.updateSnum(order.getCid());
        //待确认订单
        return i+"";
    }

dao

//查询付款订单
    @Select("select c.*,t.tnum,o.oid,o.ucard,o.urealname,o.oprice,o.seatnum,o.state,o.odate from traininfo t inner join carinfo c on c.tid=t.tid inner join orderinfo o on c.cid=o.cid where o.oid=#{oid}")
    public CarTrainOrder selectFkOrder(int oid); 
    //查看全部已付款订单
    @Select("select c.*,t.tnum,o.oid,o.ucard,o.urealname,o.oprice,o.seatnum,o.state,o.odate from traininfo t inner join carinfo c on c.tid=t.tid inner join orderinfo o on c.cid=o.cid where o.uid=#{uid}")
    public List<CarTrainOrder> selectAllFkOrder(int uid);
    
    
    @Select("select c.*,t.tnum,o.oid,o.ucard,o.urealname,o.oprice,o.seatnum,o.state,o.odate from traininfo t inner join carinfo c on c.tid=t.tid inner join orderinfo o on c.cid=o.cid where o.uid=#{uid} and o.odate=#{odate}")
    public List<CarTrainOrder> selectAllSearchOrder(@Param("uid")int uid,@Param("odate")String odate);

三、遇到的问题:

1）业务逻辑容易出错，考虑不全，一直在重复去改

四、解决的方法:

1）改

五、项目燃尽图更新:
