minio整合springboot解决视频文件上传下载问题

1.本地安装minio

提供官网地址下载minio官网

下载服务端

在服务端所在文件下打开cmd

启动命令

minio.exe server /data

打开地址输入默认的用户名和密码

服务地址：http://127.0.0.1:9000
默认账号：minioadmin
默认密码：minioadmin

2.Springboot整合minio

maven仓库将需要的minio依赖复制下载，注意与springboot是否适配

https://mvnrepository.com/

仓库地址

将依赖复制到pom文件中

            io.minio
            minio
            7.0.2

package com.gen.server.module.videoStreamingMedia.config;

import io.minio.errors.InvalidEndpointException;
import io.minio.errors.InvalidPortException;

        MinioClient minioClient = new MinioClient(endpoint, accessKey, secretKey);
        return minioClient;
    }

}

yml文件配置

# minio 连接参数

  endpoint: http://127.0.0.1:9000/
  accessKey: minioadmin
  secretKey: minioadmin
