MinIO基于Apache License v2.0开源协议的对象存储服务,可以做为云存储的解决方案用来保存海量的图片,视频,文档。由于采用Golang实现,服务端可以工作在Windows,Linux, OS X和FreeBSD上。配置简单,基本是复制可执行程序,单行命令可以运行起来。MinIO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。
基本概念

MinIO特点:
docker pull minio/minio:RELEASE.2022-01-03T18-22-58Z
docker run
-p 9000:9000 # 端口映射
--name minio # 容器名称
-d --restart=always # 开机启动
-e "MINIO_ACCESS_KEY=minio" # 设置access_key
-e "MINIO_SECRET_KEY=minio123" # 设置secret_key
-v /home/data:/data # 目录映射
-v /home/config:/root/.minio minio/minio server /data # 目录映射

为了以防别的服务引入文件服务的依赖时,bean无法加载,在resources中新建META-INF/spring.factories
添加配置:
org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
com.file.service.impl.FileStorageServiceImpl
以上即完成了springboot整合MinIO,欢迎点赞,收藏。
