四、核心代码
4.1 查询菜品类型
@RequestMapping(value = "/getByPage", method = RequestMethod.GET) @ApiOperation(value = "查询菜品类型") public Result<IPage<DishType>> getByPage(@ModelAttribute DishType dishType ,@ModelAttribute PageVo page){ QueryWrapper<DishType> qw = new QueryWrapper<>(); if(!ZwzNullUtils.isNull(dishType.getTitle())) { qw.like("title",dishType.getTitle()); } if(!ZwzNullUtils.isNull(dishType.getStatus())) { qw.eq("status",dishType.getStatus()); } IPage<DishType> data = iDishTypeService.page(PageUtil.initMpPage(page),qw); return new ResultUtil<IPage<DishType>>().setData(data); }
4.2 查询菜品
@RequestMapping(value = "/getByPage", method = RequestMethod.GET) @ApiOperation(value = "查询菜品") public Result<IPage<DishVariety>> getByPage(@ModelAttribute DishVariety dishVariety ,@ModelAttribute PageVo page){ QueryWrapper<DishVariety> qw = new QueryWrapper<>(); if(!ZwzNullUtils.isNull(dishVariety.getTitle())) { qw.like("title",dishVariety.getTitle()); } if(!ZwzNullUtils.isNull(dishVariety.getType())) { qw.eq("type",dishVariety.getType()); } if(!ZwzNullUtils.isNull(dishVariety.getContent())) { qw.like("content",dishVariety.getContent()); } IPage<DishVariety> data = iDishVarietyService.page(PageUtil.initMpPage(page),qw); User currUser = securityUtil.getCurrUser(); for (DishVariety vo : data.getRecords()) { QueryWrapper<DishCollect> collQw = new QueryWrapper<>(); collQw.eq("collect_id",currUser.getId()); collQw.eq("dish_id",vo.getId()); vo.setCollectFlag(iDishCollectService.count(collQw)); QueryWrapper<DishOrder> orderQw = new QueryWrapper<>(); orderQw.eq("dish_id",vo.getId()); orderQw.eq("status","已加购"); orderQw.last("limit 1"); DishOrder order = iDishOrderService.getOne(orderQw); vo.setBuyNumber(order == null ? BigDecimal.ZERO : order.getNumber()); } return new ResultUtil<IPage<DishVariety>>().setData(data); }
4.3 加购菜品
@RequestMapping(value = "/addOne", method = RequestMethod.GET) @ApiOperation(value = "加购") public Result<DishOrder> addOne(@RequestParam String id, @RequestParam BigDecimal number){ DishVariety dish = iDishVarietyService.getById(id); if(dish == null) { return ResultUtil.error("菜品不存在"); } User currUser = securityUtil.getCurrUser(); QueryWrapper<DishOrder> qw = new QueryWrapper<>(); qw.eq("dish_id",dish.getId()); qw.eq("status","已加购"); qw.eq("order_id",currUser.getId()); qw.last("limit 1"); DishOrder order = iDishOrderService.getOne(qw); if(order != null) { order.setNumber(order.getNumber().add(number)); iDishOrderService.saveOrUpdate(order); return ResultUtil.success(); } DishOrder o = new DishOrder(); o.setDishId(dish.getId()); o.setTitle(dish.getTitle()); o.setType(dish.getType()); o.setContent(dish.getContent()); o.setImage(dish.getImage()); o.setPrice(dish.getPrice()); o.setStatus("已加购"); o.setNumber(number); o.setOrderId(currUser.getId()); o.setOrderName(currUser.getNickname()); o.setOrderTime(DateUtil.now()); iDishOrderService.saveOrUpdate(o); return ResultUtil.success(); }
4.4 新增菜品收藏
@RequestMapping(value = "/addOne", method = RequestMethod.GET) @ApiOperation(value = "新增收藏") public Result<DishCollect> addOne(@RequestParam String id){ DishVariety dish = iDishVarietyService.getById(id); if(dish == null) { return ResultUtil.error("菜品不存在"); } User currUser = securityUtil.getCurrUser(); QueryWrapper<DishCollect> qw = new QueryWrapper<>(); qw.eq("dish_id",id); qw.eq("collect_id",currUser.getId()); if(iDishCollectService.count(qw) > 0L) { return ResultUtil.success(); } DishCollect dishCollect = new DishCollect(); dishCollect.setDishId(dish.getId()); dishCollect.setTitle(dish.getTitle()); dishCollect.setType(dish.getType()); dishCollect.setContent(dish.getContent()); dishCollect.setImage(dish.getImage()); dishCollect.setPrice(dish.getPrice()); dishCollect.setCollectId(currUser.getId()); dishCollect.setCollectName(currUser.getNickname()); dishCollect.setCollectTime(DateUtil.now()); iDishCollectService.saveOrUpdate(dishCollect); return ResultUtil.success(); }
4.5 新增菜品留言
@RequestMapping(value = "/insert", method = RequestMethod.POST) @ApiOperation(value = "新增菜品留言") public Result<Message> insert(Message message){ User currUser = securityUtil.getCurrUser(); message.setUserId(currUser.getId()); message.setUserName(currUser.getNickname()); message.setUserTime(DateUtil.now()); message.setReplyContent(""); message.setReplyName(""); message.setReplyTime(""); message.setReplyId(""); iMessageService.saveOrUpdate(message); return new ResultUtil<Message>().setData(message); }
