SpringBoot整合Minio的详细步骤 SpringBoot整合Minio详细步骤阅读详情

前言

1.什么是Minio？
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。（我的理解就是对象存储服务。跟fastdfs很像，有服务端和客户端）

docker安装Minio（别问我为什么用docker。两个字简单方便）

#拉取镜像
docker pull minio

#拉取镜像
docker run 
-p 9001:9000 -p 9090:9090  # 第一个端口是服务端口，第二个是客户端（9001是宿主机端口，9000是容器内部端口）
--net=host  #表示容器和宿主机共享一个ip
--name minio #容器名称
-d --restart=always  #自启动
-e "MINIO_ACCESS_KEY=minio"  #客户端账号（有点像Mysql的用户密码）
-e "MINIO_REGION=cn-north-1" 
-e "TZ=Asia/Beijing"  #设置容器时区（不设置会报错）
-e "MINIO_SECRET_KEY=minio123456" #客户端密码 （密码必须不得少于8位不然启动不了） 
-v /minio/data:/data  #挂载目录将/minio/data挂载到容器的/data目录，防止数据丢失
-v /minio/config:/root/.minio  minio/minio server /data 
--console-address ":9090" -address ":9001"

没有设置时区时会报错

2. 启动成功后访问http://ip:9090,进入控制台页面
在这里插入图片描述
用户密码就是上面启动命令里的账号密码

Buckets：我的理解就是一个打的文件盘，而下面的project和file是一个个文件夹，objects就是文件个数
3. SpringBoot简单使用

测试

当文件名相同时会覆盖掉之前的文件。

上传2G文件耗时110秒左右，总的来说还行
总结：工作中用到的存储文件的方式是nas盘，最近由于文件越来越多，导致磁盘空间不可用，就想找个别的东西代替nas存储文件，偶然了解到minio分布式文件存储。本次demo只是简单介绍和使用，学习之路任到重远，欢迎指点
