Spring Boot集成Minio插件快速入门

1 Minio介绍

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。以下是 MinIO 的一些主要特点和优势:

  1. 兼容性: MinIO 使用标准的 Amazon S3 API,这意味着它与现有的 S3 应用程序和工具兼容,可以无缝替换 Amazon S3。

  2. 高性能: MinIO 借助于其分布式架构和优化的存储引擎,在处理大规模数据时表现出色。它可以水平扩展以满足各种工作负载需求。

  3. 轻量级: MinIO 的设计注重简单性和效率,因此它是一个轻量级的服务。这使得它易于部署、管理和维护。

  4. 高可用性: MinIO 支持数据的多副本复制和故障转移,确保数据的可靠性和高可用性。它可以在节点故障时自动进行数据修复和重平衡。

  5. 安全性: MinIO 提供多种安全功能,包括加密传输、访问控制列表 (ACLs)、策略管理和身份验证机制,以确保数据的保密性和完整性。

  6. 灵活性: MinIO 可以在各种环境中部署,包括本地数据中心、云环境和容器化环境。它支持多种存储后端,包括本地磁盘、分布式文件系统和对象存储。

2 Minio环境搭建

2.1 docker环境下

采用docker-compose搭建:

bash 复制代码
# 可参考 https://docs.min.io/docs/minio-docker-quickstart-guide.html
version: '3'
services:
  minio:
    image: minio/minio:latest                                    # 原镜像`minio/minio:latest`
    container_name: minio                                        # 容器名为'minio'
    restart: unless-stopped                                              # 指定容器退出后的重启策略为始终重启,但是不考虑在Docker守护进程启动时就已经停止了的容器
    volumes:                                                     # 数据卷挂载路径设置,将本机目录映射到容器目录
      - "./minio/data:/data"
      - "./minio/minio:/minio"
      - "./minio/config:/root/.minio"
    environment:                                      # 设置环境变量,相当于docker run命令中的-e
      TZ: Asia/Shanghai
      LANG: en_US.UTF-8
      MINIO_PROMETHEUS_AUTH_TYPE: "public"
      MINIO_ACCESS_KEY: "root"                        # 登录账号
      MINIO_SECRET_KEY: "password"                    # 登录密码
    command: server /data  --console-address ":9001"
    logging:
      driver: "json-file"
      options:
        max-size: "100m"
    ports:                              # 映射端口
      - "9000:9000" # 文件上传&预览端口
      - "9001:9001" # 控制台访问端口

启动服务:

bash 复制代码
docker-compose -f docker-compose-minio.yml -p minio up -d

启动后:

访问地址:ip地址:9001/minio 登录账号密码:root/password

2.2 Linux环境下(非docker容器下)

下载并授权限:

bash 复制代码
wget https://dl.min.io/sever/minio/release/linux-amd64/minio
chmod +x minio    //添加执行权限

启动minio服务:

bash 复制代码
MINIO_ROOT_USER=root MINIO_ROOT_PASSWORD=password ./minio server /data/minio/data --console-address ":9001"
  • 用户名为"root"
  • 密码为"password"
  • 数据存储路径为"/data/minio/data"
  • 控制台页面的访问端口为"9091"

2.3 Windows环境下

下载资源:

MinIO | S3 & Kubernetes Native Object Storage for AI

创建文件夹:

下载完成之后再合适的目录下创建三个必要的文件夹 ,分别是bin,data,logs文件夹

安装位置根据自身需求选择就好,我选在D盘的minio文件下

将minio.exe放入到bin中

然后执行命令(账号密码可通过命令行自行配置):

bash 复制代码
D:\minio\bin\minio.exe server D:\minio\data --console-address ":9001" --address ":9000"

2.4 运行成功后访问

3 springboot整合代码实现

3.1 写代码前的准备

创建桶:

获取accessKey和secretKey:

3.2 编写代码

application.yaml:

bash 复制代码
server:
  port: 8088

minio:
  endpoint: http://127.0.0.1:9000 #Minio服务所在地址
  bucketName: miniotest #存储桶名称
  accessKey: JW38e2AR9G5DgvmUCa51 #访问的key
  secretKey: rK5zgSxAyUwqgIfSWmec9osxDPvyN2qoEqX3MxZa #访问的秘钥
