用户端历史订单模块：

查询历史订单

OrderController

  /*** 历史订单*/@GetMapping("/historyOrders")@ApiOperation(value = "历史订单")public Result<PageResult> page(int page, int pageSize, Integer status) {PageResult pageResult = orderService.pageQuery4User(page, pageSize, status);return Result.success(pageResult);}

OrderService

 /*** 分页查询用户订单*/PageResult pageQuery4User(int page, int pageSize, Integer status);

OrderServiceImpl

/*** 分页查询用户订单*/@Overridepublic PageResult pageQuery4User(int pageNum, int pageSize, Integer status) {Page<Orders> page = new Page<>(pageNum, pageSize);OrdersPageQueryDTO ordersPageQueryDTO = new OrdersPageQueryDTO();ordersPageQueryDTO.setUserId(BaseContext.getCurrentId());ordersPageQueryDTO.setStatus(status);//查询条件LambdaQueryWrapper<Orders> queryWrapper = new LambdaQueryWrapper<>();queryWrapper.eq(Orders::getUserId, BaseContext.getCurrentId());if (status != null) {queryWrapper.eq(Orders::getStatus, status);}if (ordersPageQueryDTO.getNumber() != null && !ordersPageQueryDTO.getNumber().isEmpty()) {queryWrapper.like(Orders::getNumber, ordersPageQueryDTO.getNumber());}if (ordersPageQueryDTO.getPhone() != null && !ordersPageQueryDTO.getPhone().isEmpty()) {queryWrapper.like(Orders::getPhone, ordersPageQueryDTO.getPhone());}if (ordersPageQueryDTO.getBeginTime() != null) {queryWrapper.ge(Orders::getOrderTime, ordersPageQueryDTO.getBeginTime());}if (ordersPageQueryDTO.getEndTime() != null) {queryWrapper.le(Orders::getOrderTime, ordersPageQueryDTO.getEndTime());}Page<Orders> ordersPage = orderMapper.selectPage(page, queryWrapper);List<OrderVO> list = new ArrayList<>();if (ordersPage != null && ordersPage.getTotal() > 0) {for (Orders orders : ordersPage.getRecords()) {Long orderId = orders.getId();LambdaQueryWrapper<OrderDetail> orderDetailLambdaQueryWrapper = new LambdaQueryWrapper<>();orderDetailLambdaQueryWrapper.eq(OrderDetail::getOrderId, orderId);List<OrderDetail> orderDetails = orderDetailMapper.selectList(orderDetailLambdaQueryWrapper);OrderVO orderVO = new OrderVO();BeanUtils.copyProperties(orders, orderVO);orderVO.setOrderDetailList(orderDetails);list.add(orderVO);}}assert ordersPage != null;//用于断言return new PageResult(ordersPage.getTotal(), list);}

查询订单详情

OrderController

  /*** 订单详情*/@GetMapping("/orderDetail/{id}")@ApiOperation(value = "订单详情")public Result<OrderVO> details(@PathVariable Long id) {OrderVO orderVO = orderService.details(id);return Result.success(orderVO);}

OrderService

/*** 订单详情*/OrderVO details(Long id);

OrderServiceImpl

/*** 订单详情*/@Overridepublic OrderVO details(Long id) {Orders orders = orderMapper.selectById(id);LambdaQueryWrapper<OrderDetail> queryWrapper = new LambdaQueryWrapper<>();queryWrapper.eq(OrderDetail::getOrderId, id);List<OrderDetail> orderDetailList = orderDetailMapper.selectList(queryWrapper);OrderVO orderVO = new OrderVO();BeanUtils.copyProperties(orders, orderVO);orderVO.setOrderDetailList(orderDetailList);return orderVO;}
