前言

本篇博客用于记录苍穹外卖Day09用户端历史订单、商家端订单管理的学习，由于课程中直接跳过该部分的讲解，所有在这我会全过程进行分析以及编码。

注意：将查询历史订单不显示的问题我放在最前面了，因为一开始提供给我们的资料时间是没有格式化的，我们只需将时间格式化，订单数据即可显示在你的小程序端，在你的Orders实体类中下单时间和结账时间加上以下代码即可

	//下单时间
    @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd HH:mm:ss")
    private LocalDateTime orderTime;

    //结账时间
    @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd HH:mm:ss")
    private LocalDateTime checkoutTime;

任务是：完成用户端历史订单模块、商家端订单管理模块相关业务新功能开发和已有功能优化，具体如下：

用户端历史订单模块：

• 查询历史订单
• 查询订单详情
• 取消订单
• 再来一单

商家端订单管理模块：

• 订单搜索
• 各个状态的订单数量统计
• 查询订单详情
• 接单
• 拒单
• 取消订单
• 派送订单
• 完成订单

功能优化：

优化用户下单功能，加入校验逻辑，如果用户的收货地址距离商家门店超出配送范围（配送范围为5公里内），则下单失败。

用户端

查询历史订单

效果图：

接口文档：

代码：

• controller

	@GetMapping("/historyOrders")
    @ApiOperation("分页查询历史订单")
    public Result<PageResult> page(OrdersPageQueryDTO ordersPageQueryDTO){
        log.info("分页查询历史订单：{}",ordersPageQueryDTO);
        PageResult pageResult=orderService.page(ordersPageQueryDTO);
        return Result.success(pageResult);
    }

• serviceImpl

	//分页查询订单数据
    public PageResult page(OrdersPageQueryDTO ordersPageQueryDTO) {
        PageHelper.startPage(ordersPageQueryDTO.getPage(),ordersPageQueryDTO.getPageSize());

        ordersPageQueryDTO.setUserId(BaseContext.getCurrentId());

        Page<Orders> page=orderMapper.pageQuery(ordersPageQueryDTO);

        //将查询到的orders封装成orderVO
        //通过ordersId查出ordersDetails的数据存进orderVO
        List<OrderVO> list=new ArrayList<>();
        if(page!=null&&page.size()>0){
            for (Orders orders : page) {
