Minlo说明
Minio是Apcche旗下的一款开源的轻量级文件服务器基于对象存储协议是基于Apache License v2.0开源可用于商务。Minio主要用来存储非结构化的数据类似文件图片照片日志文件各类备份文件等按照官网描述文件的大小从几KB到5TB。Minio提供了非常方便友好的界面并且文档也是非常丰富具体可以参考它的文档https://docs.min.io/cn/Minlo作用类似于FastDFS和阿里云的OSS进行对象存储安装minlo服务器参考https://blog.csdn.net/u010189683/article/details/108171562
1、添加依赖
!--minio方案--
dependencygroupIdio.minio/groupIdartifactIdminio/artifactIdversion7.0.2/version
/dependency
dependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-configuration-processor/artifactIdoptionaltrue/optional
/dependency2、添加配置项
## minio配置
minio:endpoint: http://192.168.179.131:9000/accessKey: adminsecretKey: admin123456 3、配置项和工具类
