本文介绍了如何使用阿里云OSS进行文件的上传和删除操作，包括开通服务、创建bucket、配置凭证、上传MultipartFile并设置公开访问。通过实例展示了如何在Spring MVC应用中实现文件上传和删除功能。

1.前往阿里云开通oss

2.创建bucket

![在这里插入图片描述](https://img-blog.csdnimg.cn/d974d5acd25241d7b358f249dfeb4c99.png?x-oss-process=image/watermark,type_ZHJvaWRzYW5zZmFsbGJhY2s,shadow_50,text_Q1NETiBA5LiN6KiA5byD44CB,size_20,color_FFFFFF,t_70,g_se,x_16

3. 获取AccessKeyId、AccessKeySecret

4.获取EndPoint

6.添加maven依赖
