在这里插入图片描述
前端

/*** 创建订单*/async createOrder(){const totalPrice=this.data.totalPrice; // 请求体 总价const address=this.data.address.provinceName+this.data.address.cityName+this.data.address.countyName+this.data.address.detailInfo; // 请求体  收货地址const consignee=this.data.address.userName; // 请求体 收货人const telNumber=this.data.address.telNumber; // 请求体 联系电话let goods=[];this.data.cart.forEach(v=>goods.push({goodsId:v.id,goodsNumber:v.num,goodsPrice:v.price,goodsName:v.name,goodsPic:v.proPic}))const orderParam={totalPrice,address,consignee,telNumber,goods}const res=await requestUtil({url:"/my/order/create",method:"POST",data:orderParam})console.log(res.orderNo);},

后端：(加下事务)

    /*** 创建订单，返回订单号* @param order* @param token* @return*/@RequestMapping("/create")@Transactionalpublic R create(@RequestBody Order order, @RequestHeader(value="token") String token){System.out.println("token:"+token);// 通过token获取openidClaims claims = JwtUtils.validateJWT(token).getClaims();if(claims!=null){System.out.println("openid="+claims.getId());order.setUserId(claims.getId());}order.setOrderNo("JAVA"+DateUtil.getCurrentDateStr());order.setCreateDate(new Date());OrderDetail[] goods = order.getGoods();// 添加订单到数据库orderService.save(order);// 添加订单详情到数据库for(int i=0;i<goods.length;i++){OrderDetail orderDetail=goods[i];orderDetail.setMId(order.getId());orderDetailService.save(orderDetail);}Map<String,Object> resultMap=new HashMap<>();resultMap.put("orderNo",order.getOrderNo());return R.ok(resultMap);}
