该博客介绍了如何在SpringBoot应用中集成Minio对象存储服务，包括添加依赖、配置Minio客户端、创建和检查bucket、上传与删除文件、获取文件列表以及预签名下载链接的方法。

https://docs.min.io/官方文档
下载后启动，例如我的：.\minio.exe server F:\tools\minio
启动成功后如下显示，里面包含控制台访问接口，用户名密码
在这里插入图片描述
其他的先不说了，下面直接最简单的使用方式贴出来。
基于springboot的依赖，java的额可以参考文档

<!-- minio -->
		<dependency>
			<groupId>io.minio</groupId>
			<artifactId>minio</artifactId>
			<version>7.0.2</version>
		</dependency>

配置类

/**
 * minio配置类，这三个信息可以在启动成功后窗口上获取
 * @author Administrator
 *
 */
@Data
@Configuration
public class MinioConfig {

	private final static String endpoint="http://127.0.0.1:9000";

	private final static String accessKey="minioadmin";

	private final static String secretKey="minioadmin";
	
	
	@Bean
	public MinioClient getMinioClient() throws InvalidEndpointException, InvalidPortException {
		MinioClient minioClient = new MinioClient(endpoint, accessKey, secretKey);
		return minioClient;
	}
}
