1.controller层 根据跳转页面显示具体的商品详情内容
@RequestMapping("/to_detail/{goodsId}")
String list(Model model, MiaoshaUser user,@PathVariable("goodsId") long goodsId) {
model.addAttribute("user", user);
GoodsVo goods=goodsService.getGoodsVoByGoodsId(goodsId);
model.addAttribute("goods", goods);
long startDate = goods.getStartDate().getTime();
long endDate = goods.getEndDate().getTime();
long currentTimeMillis = System.currentTimeMillis();
int miaoshaStatus=0;
int remainSeconds=0;
if(currentTimeMillis<startDate) {//秒杀还没开始 进入倒计时
miaoshaStatus=0;
remainSeconds=(int) ((startDate-currentTimeMillis)/1000);
} else if(currentTimeMillis>endDate) {//秒杀已经结束
miaoshaStatus=2;
remainSeconds=-1;
}else {//秒杀正在进行中
miaoshaStatus=1;
remainSeconds=0;
}
model.addAttribute("miaoshaStatus", miaoshaStatus);
model.addAttribute("remainSeconds", remainSeconds);
return "goods_detail";
}
3. 增加 service层 和 dao层
//service层
public GoodsVo getGoodsVoByGoodsId(long goodsId) {
return goodsDao.getGoodsVoByGoodsId(goodsId);
}
//dao层
@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 goods_id =#{goodsId}")
public GoodsVo getGoodsVoByGoodsId(@Param("goodsId")long goodsId);
