使用SpringBoot+MyBatis架构的大文件上传功能，支持断点续传

SpringBoot + Mybatis + MySql 搭建后端大文件上传项目

悄悄说 目前代码中只包含后端代码

前端代码参考git地址: bigFileUploader

参考博客地址: https://luoliangdsga.github.io

上传有哪些功能？

• 文件及文件夹上传功能
  • 支持文件的上传功能
  • 支持文件夹的上传功能
• 文件断点续传功能
  • 文件的断点续传功能
  • 使用mysql存储已上传的分片信息

开始

需要准备好基础软件环境

• Java
• Node(前台需要)
• MySQL

后端

新建一个SpringBoot项目，我这里使用的是SpringBoot2，引入mvc，jpa，mysql相关的依赖。

在yml中配置mvc以及数据库连接等属性
