## 二、项目介绍 ##

项目描述：这是一个**基于SpringBoot+微信小程序框架**开发的酒店预订小程序系统。首先，这是一个**前后端分离**的项目，代码简洁规范，注释说明详细，易于理解和学习。其次，这项目功能丰富，具有一个酒店预订小程序系统该有的所有功能。

项目功能：此项目分为**两个**角色：**普通用户**和**管理员**。**普通用户**有微信授权登录、浏览房间信息、提交房间预订订单、浏览酒店图集和配套设施信息、浏览公告信息、管理个人基本信息、查看个人订单信息、管理个人评价信息、发布评价信息等等功能。**管理员**有管理所有房间信息、管理所有订单信息、管理所有用户信息、管理所有评价信息、管理所有公告信息、管理所有图集信息、浏览收益图表数据等等功能。

应用技术：SpringBoot + 微信小程序 + MySQL + MyBatis + Redis + ElementUI + Vue + Vant Weapp

运行环境：IntelliJ IDEA2019.3.5 + 微信开发者工具（项目压缩包中自带）+ MySQL5.7（项目压缩包中自带) + Redis5.0.5（项目压缩包中自带） + JDK1.8 + Maven3.6.3（项目压缩包中自带）+ Node14.16.1（项目压缩包中自带）

## 四、主要代码 ##

**1.提交预订房间订单代码：**

/**
     * 提交订单操作
     * @param orderDTO
     * @return
     */
    @Override
    public ResponseDTO<Boolean> submitOrder(OrderDTO orderDTO) {

        }
        UserDTO loginUserDTO = loginUserResponse.getData();
        // 进行统一表单验证

            return ResponseDTO.errorByMsg(validate);
        }
        Room room = roomMapper.selectByPrimaryKey(orderDTO.getRoomId());
