真正的礼貌表现在对人的善意上。——卢俊
首先是安装，注意选择合对应的的系统和安装方式
https://min.io/docs/minio/kubernetes/upstream/
例如我在windows。直接下载
https://dl.min.io/server/minio/release/windows-amd64/minio.exe
然后运行
minio.exe server D:\
打开localhost:9000，默认minioadmin:minioadmin进入界面
然后是代码实现上传下载，先引入依赖
<dependency> <groupId>io.minio</groupId> <artifactId>minio</artifactId> <version>8.5.6</version> </dependency>
然后是代码：
package com.ruben; import io.minio.*; import io.minio.errors.MinioException; import java.io.ByteArrayInputStream; import java.io.IOException; import java.io.InputStream; public class MinioDemo { public static void main(String[] args) { try { // 初始化客户端 MinioClient minioClient = MinioClient.builder() .endpoint("http://localhost:9000") // 更新为你的Minio服务器地址 .credentials("minioadmin", "minioadmin") // 使用你的访问和密钥 .build(); // 检查一个存储桶是否存在 BucketExistsArgs testbucket = BucketExistsArgs.builder().bucket("testbucket").build(); boolean isExist = minioClient.bucketExists(testbucket); if (!isExist) { // 创建一个名为'testbucket'的存储桶 minioClient.makeBucket(MakeBucketArgs.builder().bucket("testbucket").build()); } // 上传一个文件 String content = "Hello, Minio!"; InputStream stream = new ByteArrayInputStream(content.getBytes()); ObjectWriteResponse res = minioClient.putObject(PutObjectArgs.builder().bucket("testbucket") .object("hello.txt").contentType("text/plain") .stream(stream, content.length(), -1).build()); // 下载文件 InputStream downloadedStream = minioClient.getObject(GetObjectArgs.builder() .bucket("testbucket").object("hello.txt").build()); String downloadedContent = readFromInputStream(downloadedStream); System.out.println("Downloaded content: " + downloadedContent); downloadedStream.close(); } catch (MinioException e) { System.out.println("Error occurred: " + e); } catch (Exception e) { e.printStackTrace(); } } public static String readFromInputStream(InputStream is) throws IOException { byte[] buffer = new byte[1024]; int bytesRead; StringBuilder sb = new StringBuilder(); while ((bytesRead = is.read(buffer)) != -1) { sb.append(new String(buffer, 0, bytesRead)); } return sb.toString(); } }
