MinIo的安装，问题的解决、SpringBoot的集成

一、下载MinIo的地址

https://min.io/download#/windows

二、如何进行启动

• 绝对路径minio.exe server F:Data --console-address ":9001"
• 访问页面http://192.168.1.100:9001/
• 输入用户名：minioadmin 输入密码：minioadmin

三、查看页面的相关的一些详情

四、SpringBoot集成minio

• 引入依赖包，如果单纯引入minio的，会出现以下的报错现象

• 解决方案，导入大于4.8.1的okhttp

• 启动如果报错

15:07:14.933 [mAIn] ERROR org.springframework.boot.diagnostics.LoggingFailureAnalysisReporter - *************************** AppLICATION FAILED TO START *************************** Description: An attempt was made to call a method that does not exist. The attempt was made from the following location: okio.Segment.writeTo(Segment.kt:169) The following method did not exist: kotlin.collections.ArraysKt.copyInto([B[BIII)[B

引入依赖

io.miniominio8.3.4com.squareup.okhttp3okhttpcom.squareup.okhttp3okhttp4.9.1org.jetbrains.kotlinkotlin-stdlib1.3.50

• 如果出现执行报错，可能是端口错了

Resolved [io.minio.errors.InvalidResponseException: Non-XML response from server. Response code: 400, Content-Type: text/xml; charset=utf-8, body:InvalidArgumentS3 API Requests must be made to API port.0]

五、bucket的命名规则

• bucket名称的长度必须介于 3（最小）和 63（最大）字符之间。
• bucket名称只能由小写字母、数字、点 (.) 和连字符 (-) 组成。
• bucket名称不得包含两个相邻的句点，或与连字符相邻的句点。
• bucket名称不得格式化为 IP 地址（例如，192.168.5.4）。
• bucket名称不能以前缀 xn-- 开头。
• bucket名称不得以后缀 -s3alias 结尾。该后缀是为接入点别名保留的。
• bucket名称在分区内必须是唯一的。

六、代码实现
