使用Spring Boot 可以非常方便、快速搭建项目,使我们不用关心框架之间的兼容性,适用版本等各种问题,我们想使用任何东西,仅仅添加一个配置就可以。
提示：以下是本篇文章正文内容，下面案例可供参考
MinIO 是一个基于Apache License v2.0开源协议的对象存储服务。它兼容亚马逊S3云存储服务接口，非常适合于存储大容量非结构化的数据，例如图片、视频、日志文件、备份数据和容器/虚拟机镜像等，而一个对象文件可以是任意大小，从几kb到最大5T不等。
代码如下（示例）：
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.4.1</version>
<relativePath/>
</parent>
<dependencies>
<dependency>
<groupId>io.minio</groupId>
<artifactId>minio</artifactId>
<version>8.0.3</version>
</dependency>
</dependencies>
