手把手教你用Flutter / java打造AI记账App前后端🚀

一、前言

大家好，前不久和朋友一起做了个多人记账软件。功能比较完整，已经上架了应用市场。不过这类软件太卷了，运营起来比较麻烦，所以决定开源出来，分享下我的开发过程，供大家参考学习，希望有所帮助。

整个教程包括前后端，会做成一个合集，逐步更新，欢迎关注。

好，首先说一下技术选型。
考虑到多端开发成本，前端用的flutter，后端用的java，数据库用的mysql和redis，ai调的coze

来看看整体的功能吧

好了，第一集先到这，下一集开始搭建项目。

二、项目整体框架

这节课做三个事，讲一下整体项目、叠甲、带大家跑起来

1. 整体架构

是个很简单的项目，但是还比较好玩，功能实现也比较完整

  1. 前后端鉴权：jwt
  2. 缓存：redis
  3. 数据库：mysql
  4. 前端：flutter、dart、vue（落地页）
  5. 后端：java springboot，单体
  6. 负载均衡：nginx
  7. 文件存储：腾讯云cos
  8. 前端状态管理：getx
  9. 前端ui框架：tdesign

2. 功能模块

1. 登录

  1. 手机验证码登录
  2. 苹果登录
  3. 微信登录

2. 记账

  1. 手动输入记账
  2. 语音记账
  3. 快捷记账

3. 账单列表

  1. 查询账单列表

4. 账本

  1. 多人账本

5. 与coze交互

6. 数据可视化
