1.定义一个GoodsDetailVo类来接收从ajax页面传来的数据；
package com.ryan.miaosha.vo;
import com.ryan.miaosha.dao.MiaoshaUser;
public class GoodsDetailVo {
private MiaoshaUser user;
private int miaoshaStatus=0;
private int remainSeconds=0;
private GoodsVo goods;
public MiaoshaUser getUser() {
return user;
}
public void setUser(MiaoshaUser user) {
this.user = user;
}
public int getMiaoshaStatus() {
return miaoshaStatus;
}
public void setMiaoshaStatus(int miaoshaStatus) {
this.miaoshaStatus = miaoshaStatus;
}
public int getRemainSeconds() {
return remainSeconds;
}
public void setRemainSeconds(int remainSeconds) {
this.remainSeconds = remainSeconds;
}
public GoodsVo getGoods() {
return goods;
}
public void setGoods(GoodsVo goods) {
this.goods = goods;
}
}
1.如何利用ajax获取页面的参数
common.js里面
// 获取url参数
function g_getQueryString(name) {
var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)");
var r = window.location.search.substr(1).match(reg);
if(r != null) return unescape(r[2]);
return null;
};
//设定时间格式化函数，使用new Date().format("yyyyMMddhhmmss");
Date.prototype.format = function (format) {
var args = {
"M+": this.getMonth() + 1,
"d+": this.getDate(),
"h+": this.getHours(),
"m+": this.getMinutes(),
"s+": this.getSeconds(),
};
if (/(y+)/.test(format))
format = format.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
for (var i in args) {
var n = args[i];
if (new RegExp("(" + i + ")").test(format))
format = format.replace(RegExp.$1, RegExp.$1.length == 1 ? n : ("00" + n).substr(("" + n).length));
}
return format;
};

1.goods_detail controller层静态化
页面缓存
@RequestMapping("/detail/{goodsId}")
@ResponseBody
Result<GoodsDetailVo> detail(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);
GoodsDetailVo goodsDetailVo=new GoodsDetailVo();
goodsDetailVo.setGoods(goods);
goodsDetailVo.setMiaoshaStatus(miaoshaStatus);
goodsDetailVo.setRemainSeconds(remainSeconds);
goodsDetailVo.setUser(user);
return Result.success(goodsDetailVo);
}
1.miaoshaController改为静态
package com.imooc.miaosha.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

/**

@RequestMapping(value="/do_miaosha", method=RequestMethod.POST)
@ResponseBody

}
//判断库存

//判断是否已经秒杀到了
MiaoshaOrder order = orderService.getMiaoshaOrderByUserIdGoodsId(user.getId(), goodsId);

}
//减库存 下订单 写入秒杀订单
OrderInfo orderInfo = miaoshaService.miaosha(user, goods);
return Result.success(orderInfo);
}
}
1.订单支付详情静态化
@RequestMapping("/detail")
@ResponseBody
Result<OrderDetailVo> orderDetail(Model model,MiaoshaUser user,@RequestParam("orderId") long orderId) {

}

}
Long id = order.getGoodsId();
GoodsVo goodsVoByGoodsId = goodsService.getGoodsVoByGoodsId(id);
OrderDetailVo orderInfo=new OrderDetailVo();
orderInfo.setGoodsVo(goodsVoByGoodsId);
orderInfo.setOrderInfo(order);
return Result.success(orderInfo);
}
