菜品起停售

---

需求分析

如果执行停售操作，则包含此菜品的套餐也需要停售

DishController

/**
     * 菜品起售停售
     * @param status
     * @param id
     * @return
*/
@PostMapping("/status/{status}")
@ApiOperation("菜品起售停售")
public Result<String> startOrStop(@PathVariable Integer status, Long id){
    dishService.startOrStop(status,id);
    return Result.success();
}

DishService

/**
     * 菜品起售停售
     * @param status
     * @param id
*/
void startOrStop(Integer status, Long id);

DishServiceImpl

/**

    Dish dish = Dish.builder()
        .id(id)
        .status(status)
        .build();
    dishMapper.update(dish);

    if (status == StatusConstant.DISABLE) {
        // 如果是停售操作，还需要将包含当前菜品的套餐也停售
        List<Long> dishIds = new ArrayList<>();
        dishIds.add(id);
        // select setmeal_id from setmeal_dish where dish_id in (?,?,?)
        List<Long> setmealIds = setmealDishMapper.getSetmealIdsByDishIds(dishIds);
        if (setmealIds != null && setmealIds.size() > 0) {
            for (Long setmealId : setmealIds) {
                Setmeal setmeal = Setmeal.builder()
                    .id(setmealId)
                    .status(StatusConstant.DISABLE)
                    .build();
                setmealMapper.update(setmeal);
            }
        }
    }
}
