SpringBoot整合Minio实现上传文件的完整步骤记录

2022-05-26 09:59:23 作者：徐小白

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,下面这篇文章主要给大家介绍了关于SpringBoot整合Minio实现上传文件的完整步骤,需要的朋友可以参考下

Minio

上传文件如果不使用云服务的话,需要本地搭建,一般选择 FastDFS 但是 FastDFS 安装比较复杂,今天了解一款安装使用更简单的存储系统 MinIO

MinIO 是一款高性能、分布式的对象存储系统. 它是一款软件产品, 可以100%的运行在标准硬件。即X86等低成本机器也能够很好的运行MinIO。

MinIO与传统的存储和其他的对象存储不同的是：它一开始就针对性能要求更高的私有云标准进行软件架构设计。因为MinIO一开始就只为对象存储而设计。所以他采用了更易用的方式进行设计，它能实现对象存储所需要的全部功能，在性能上也更加强劲，它不会为了更多的业务功能而妥协，失去MinIO的易用性、高效性。这样的结果所带来的好处是：它能够更简单的实现局有弹性伸缩能力的原生对象存储服务。

MinIO在传统对象存储用例（例如辅助存储，灾难恢复和归档）方面表现出色。同时，它在机器学习、大数据、私有云、混合云等方面的存储技术上也独树一帜。当然，也不排除数据分析、高性能应用负载、原生云的支持。

在中国：阿里巴巴、腾讯、百度、中国联通、华为、中国移动等等9000多家企业也都在使用MinIO产品

安装 Minio

使用docker安装

拉取镜像

docker pull minio/minio

启动

docker run -p 9000:9000 -p 9001:9001 -d --name minio -v /opt/docker/minio/data:/data -v /opt/docker/minio/config:/root/.minio -e "MINIO_ROOT_USER=minio" -e "MINIO_ROOT_PASSWORD=minio@123456" minio/minio server /data --console-address ":9000" --address ":9001"

使用9000端口登录控制台

创建存储桶

设置桶权限

创建 Java 客户端

配置文件

spring:
  application:
    name: minio-demo
  servlet:
    multipart:
      max-file-size: 20MB
      max-request-size: 200MB
server:
  port: 8088

minio:
  endpoint: http://你的ip:9001
  accessKey: minio
  secretKey: minio@123456
  nginxHost: http://你的域名

配置文件配置类

package com.sqm.minio_demo.config;

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@ConfigurationProperties(prefix = "minio")
@Component
@Data

     * 密码
     */
    private String secretKey;
    /**
     * 域名
     */
    private String nginxHost;
