minio服务器在win10的上传与下载，以及修改头像Minio速看免费本地文件服务器
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
首先自己配置Minio服務器 和客戶端 請點擊 官網地址http://www.minio.org.cn
安裝完成后自己百度win10安裝。
我是用Spring boot 配置 首先導入 Minio Dependency配置
<!-- minio服務器--><dependency><groupId>io.minio</groupId><artifactId>minio</artifactId><version>8.3.0</version></dependency><dependency><groupId>me.tongfei</groupId><artifactId>progressbar</artifactId><version>0.5.3</version></dependency><dependency><groupId>com.squareup.okhttp3</groupId><artifactId>okhttp</artifactId><version>4.8.1</version></dependency>接著配置yml (yml的配置一定要對齊！！！！！) #號代表注釋
minio:#minio服務器配置endpoint: http://127.0.0.1:9002 //Minio服務器端口#minio服務器配置賬號accessKey: 自己配置的賬號#minio服務器配置密碼secretKey: 自己配置的密碼#minio服務器桶bucketName: 自己設置的桶名我的Minion客戶端界面：
接下來是我的：controller層代碼

接下來是我在前端Vue +餓了么-Ui做的管理
自己根據導入的jar包 去官方文檔 Minioclient 去使用具體的方法
SDK方法區：（自己看）

展示圖：
這是我簡單的就是文件CRUD
接下來是： 保存服務器文件并生成網絡路徑 存放在在Mysql 當中 和修改頭像功能
修改管理員的頭像 Controller層：

下面是我的數據庫：
varchar 255不夠 生成的圖片鏈接用400即可.
