MinIO是一个对象存储解决方案,它提供了一个Amazon Web Services S3兼容的API,并支持所有S3的核心特性。MinIO可以部署在任何地方——公共云或私有云、裸机基础设施、编排环境和边缘基础设施。
本文档介绍MinIO最新稳定版本RELEASE.2023-09-04T19-57-37Z在Windows平台上部署MinIO的操作、管理和开发。
上面是官网介绍,用有道翻译的,官网地址: 链接。
使用docker搭建minio环境,可以直接用官网下载minio镜像,我们先用windows环境搭建一下。
在官网下载页面,选择windows,下载的是一个minion.exe文件。我放在了d:/minio目录下,在此再创建一个data文件夹,用来储存minio上传的文件。
然后在命令行执行如下指令启动minio:
setx MINIO_ROOT_USER minioadmin
setx MINIO_ROOT_PASSWORD minioadmin
D:\minio\minio.exe server D:\minio\data\ --console-address ":9001"
看到如下就说明启动成功了:
然后通过浏览器访问:
http://localhost:9001/
进入如下登录页面:
默认用户名和密码都是minioadmin
使用docker部署就更简单了,首先拉取官方镜像:
docker pull minio/minio
拉取成功之后,执行创建和启动容器:
docker run -p 9000:9000 -p 9001:9001 minio/minio server /data --console-address ":9001"
看到如下就说明启动成功:
同样通过浏览器访问:
http://localhost:9001/
进入如下登录页面:
默认用户名和密码都是minioadmin
通过springboot框架集成minio,实现上传文件的目的。
首先创建一个springboot工程,添加如下依赖:
<!-- lombok 自动生成方法-->
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.18.24</version>
</dependency>
<!--io常用工具类 -->
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.5</version>
</dependency>
<!--常用工具类 -->
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
</dependency>
<!-- minio-->
<dependency>
<groupId>io.minio</groupId>
<artifactId>minio</artifactId>
<version>8.4.6</version>
</dependency>
在springboot的yml配置文件中添加minio环境的配置:
#minio相关配置
minio:
endpoint: http://127.0.0.1:9000
accessKey: minioadmin
secretKey: minioadmin
package com.thcb.miniodemo.config;

在springboot启动成功后连接minio
package com.thcb.miniodemo.listener;
import com.thcb.miniodemo.minio.MinioUtil;
import com.thcb.miniodemo.utils.ExceptionUtil;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.context.event.ApplicationReadyEvent;
import org.springframework.context.ApplicationListener;
import org.springframework.stereotype.Component;
/**

*
* @author thcb
* @date 2023-09-05
*/
@Component
public class ApplicationReadyListener implements ApplicationListener<ApplicationReadyEvent> {
private static final Logger log = LoggerFactory.getLogger(ApplicationReadyListener.class);
@Autowired
private MinioUtil minioUtil;
@Override
public void onApplicationEvent(ApplicationReadyEvent event) {
try {
doPostConstruct();
} catch (Exception e) {
log.error("e={}", ExceptionUtil.getExceptionMessage(e));
}
}
private void doPostConstruct() {
log.info("initMinIo");
initMinIo();
}
/**
* 初始化minio桶文件
*/
private void initMinIo() {
minioUtil.initMinIo();
}
}
写一个测试的controller,测试minio相关功能
package com.thcb.miniodemo.controller;
import com.thcb.miniodemo.minio.MinioUtil;
import com.thcb.miniodemo.utils.AjaxResult;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
/**
* TestController
*
* @author thcb
* @date 2023-09-05
*/
@RestController
@RequestMapping("/TestController")
public class TestController {
private static final Logger log = LoggerFactory.getLogger(TestController.class);
@Autowired
private MinioUtil minioUtil;
@RequestMapping("/test")
@ResponseBody
public String test() {
return "test success";
}
@PostMapping("/uploadFile")
public AjaxResult uploadFile(MultipartFile file) throws Exception {
try {
String pathUrl = minioUtil.upload2Bucket(file, MinioUtil.TEST_BUCKET);
return AjaxResult.success(pathUrl);
} catch (Exception e) {
return AjaxResult.error(e.toString());
}
}
}
使用postman调用我们写的测试接口,上传一个文件到minio
上传成功,在页面上也可以看到这个文件:
如果上传的是图片,通过返回的url,浏览器可以直接访问预览,如果是其他类型的文件,是可以通过这个返回的url进行下载的:
http://localhost:9000/test/20230908/2b31664c4a004a5cb4b2934ebf5300cd.jpg
minio的demo已经上传到csdn,需要的可以自行下载,在本文基本也把主要的核心代码都贴出来了,这个demo使用的是springboot框架,加了一些工具类,可以直接拿来用,或者新工程改个名字就能用了。demo结构截图:
demo工程地址:demo下载地址,传到了gitcode上,应该是csdn弄的一个代码仓库,和git差不多。
minio还是很方便的,从部署到使用,都可以非常快速的搭建,而且比较稳定。
