实现goods_list.html中的详情功能
<!--这句话跳转到GoodsController的detail方法下-->><td><a th:href="'/goods/to_detail/'+${goods.id}">详情</a></td>
Controller层
在GoodsController中添加一个这样的方法
//@PathVariable???@RequestMapping("/to_detail/{goodsId}")public String detail(Model model, MiaoshaUser miaoshaUser,@PathVariable("goodsId")long goodsId){model.addAttribute("user",miaoshaUser);GoodsVo goods = goodsService.getGoodsVoByGoodsId(goodsId);model.addAttribute("goods", goods);long startAt = goods.getStartDate().getTime();long endAt = goods.getEndDate().getTime();long now = System.currentTimeMillis();int miaoshaStatus = 0;int remainSeconds = 0;if(now < startAt ) {//秒杀还没开始，倒计时miaoshaStatus = 0;remainSeconds = (int)((startAt - now )/1000);}else if(now > endAt){//秒杀已经结束miaoshaStatus = 2;remainSeconds = -1;}else {//秒杀进行中miaoshaStatus = 1;remainSeconds = 0;}model.addAttribute("miaoshaStatus", miaoshaStatus);model.addAttribute("remainSeconds", remainSeconds);return "goods_detail";}
Service层
public GoodsVo getGoodsVoByGoodsId(long goodsId){int count = goodsDao.getGoodsVoByGoodsId(goodsId).getStockCount(); return goodsDao.getGoodsVoByGoodsId(goodsId);}
Dao层
@Mapperpublic interface GoodsDao {@Select("select g.*,mg.stock_count, mg.start_date, mg.end_date,mg.miaosha_price from miaosha_goods mg left join goods g on mg.goods_id = g.id")public List<GoodsVo> listGoodsVo();@Select("select g.*,mg.stock_count, mg.start_date, mg.end_date,mg.miaosha_price from miaosha_goods mg left join goods g on mg.goods_id = g.id where g.id = #{goodsId}")public GoodsVo getGoodsVoByGoodsId(@Param("goodsId")long goodsId);}
