2）后台代码
@RequestMapping(value="/selectCountOrder",produces={"application/json;charset=utf-8"})
@ResponseBody
public String selectCountOrder(){
List<CarTrainOrder> list = carSerivce.selectCountOrder();
return JSONArray.fromObject(list).toString();
}
@RequestMapping("/selectOrderByProp")
@ResponseBody
public String selectOrderByProp(Orderinfo orderinfo,HttpServletRequest request){
Carinfo car = carSerivce.selectByCid(orderinfo.getCid());
Date date=new Date();
SimpleDateFormat format=new SimpleDateFormat("yyyy-MM-dd");
String now = format.format(date);
Orderinfo selectOrderByProp = carSerivce.selectOrderByProp(orderinfo.getCid(),car.getStart_date(),now);
if(selectOrderByProp!=null){
return "1";//存在
}
return "0";
}
dao
@Select("select count(*) snum, c.begin_sta,c.end_sta,odate,c.price,t.tnum from traininfo t inner join carinfo c on c.tid=t.tid inner join orderinfo o on c.cid=o.cid where o.state!=0 group by c.cid,odate order by odate")
public List<CarTrainOrder> selectCountOrder();
@Select("select * from carinfo where cid=#{cid}")
public Carinfo selectByCid(int cid);
@Select("select o.* from orderinfo o,carinfo c where o.cid=c.cid and o.cid=#{cid} and c.start_date=#{start_date} and odate=#{odate}")
public Orderinfo selectOrderByProp(@Param("cid")int cid,@Param("start_date")String start_date,@Param("odate")String odate);
三、遇到的问题:
1）查询条件涉及多个条件，sql语句容易出错
四、解决的方法:
1）使用动态sql完成
五、项目燃尽图更新:
