MinIO是根据GNU Affero通用公共许可证v3.0发布的高性能对象存储。它与Amazon S3云存储服务兼容。使用MinIO构建用于机器学习，分析和应用程序数据工作负载的高性能基础架构。
官网地址：https://min.io/
文档地址：https://docs.min.io/
docker run -p 9000:9000--name minio1-v /mnt/data:/data-e "MINIO_ROOT_USER=AKIAIOSFODNN7EXAMPLE"-e "MINIO_ROOT_PASSWORD=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"minio/minio server /data
docker run -p 9000:9000--name minio1-v D:data:/data-e "MINIO_ROOT_USER=AKIAIOSFODNN7EXAMPLE"-e "MINIO_ROOT_PASSWORD=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"minio/minio server /data
MINIO_ROOT_USER：为用户key MINIO_ROOT_PASSWORD：为用户密钥
以上搭建的都是单机版的。想要了解分布式 的方式请查看官网文档。
这就是在win的docker上运行的。
当启动后在浏览器访问http://localhost:9000就可以访问minio的图形化界面了，如图所示：
初始化一个springboot项目大家都会，这里不多做介绍。
主要是介绍需要引入的依赖：
<!--thymeleaf模板渲染引擎--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId></dependency><!--操作minio的java客户端--><dependency><groupId>io.minio</groupId><artifactId>minio</artifactId><version>8.2.1</version></dependency><!--lombok插件--><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency>
依赖可以官方文档里找：https://docs.min.io/docs/java-client-quickstart-guide.html
下面介绍配置文件：
spring:servlet:multipart:max-file-size: 10MBmax-request-size: 10MB#minio配置minio:access-key: AKIAIOSFODNN7EXAMPLE #key就是docker初始化是设置的，密钥相同secret-key: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEYurl: http://localhost:9000bucket-name: wdhcrthymeleaf:cache: false
创建minio的配置类：
@Configuration@ConfigurationProperties(prefix = "spring.minio")@Datapublic class MinioConfiguration {private String accessKey;private String secretKey;private String url;private String bucketName;@Beanpublic MinioClient minioClient() {return MinioClient.builder().endpoint(url).credentials(accessKey, secretKey).build();}}
使用配置属性绑定进行参数绑定，并初始化一个minio client对象放入容器中。
下面就是我封装的minio client 操作minio的简单方法的组件。
@Componentpublic class MinioComp {@Autowiredprivate MinioClient minioClient;@Autowiredprivate MinioConfiguration configuration;/*** @description: 获取上传临时签名* @dateTime: 2021/5/13 14:12*/public Map getPolicy(String fileName, ZonedDateTime time) {PostPolicy postPolicy = new PostPolicy(configuration.getBucketName(), time);postPolicy.addEqualsCondition("key", fileName);try {Map<String, String> map = minioClient.getPresignedPostFormData(postPolicy);HashMap<String, String> map1 = new HashMap<>();map.forEach((k,v)->{map1.put(k.replaceAll("-",""),v);});map1.put("host",configuration.getUrl()+"/"+configuration.getBucketName());return map1;} catch (ErrorResponseException e) {e.printStackTrace();} catch (InsufficientDataException e) {e.printStackTrace();} catch (InternalException e) {e.printStackTrace();} catch (InvalidKeyException e) {e.printStackTrace();} catch (InvalidResponseException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();} catch (NoSuchAlgorithmException e) {e.printStackTrace();} catch (ServerException e) {e.printStackTrace();} catch (XmlParserException e) {e.printStackTrace();}return null;}/*** @description: 获取上传文件的url* @dateTime: 2021/5/13 14:15*/public String getPolicyUrl(String objectName, Method method, int time, TimeUnit timeUnit) {try {return minioClient.getPresignedObjectUrl(GetPresignedObjectUrlArgs.builder().method(method).bucket(configuration.getBucketName()).object(objectName).expiry(time, timeUnit).build());} catch (ErrorResponseException e) {e.printStackTrace();} catch (InsufficientDataException e) {e.printStackTrace();} catch (InternalException e) {e.printStackTrace();} catch (InvalidKeyException e) {e.printStackTrace();} catch (InvalidResponseException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();} catch (NoSuchAlgorithmException e) {e.printStackTrace();} catch (XmlParserException e) {e.printStackTrace();} catch (ServerException e) {e.printStackTrace();}return null;}/*** @description: 上传文件* @dateTime: 2021/5/13 14:17*/public void upload(MultipartFile file, String fileName) {// 使用putObject上传一个文件到存储桶中。try {InputStream inputStream = file.getInputStream();minioClient.putObject(PutObjectArgs.builder().bucket(configuration.getBucketName()).object(fileName).stream(inputStream, file.getSize(), -1).contentType(file.getContentType()).build());} catch (ErrorResponseException e) {e.printStackTrace();} catch (InsufficientDataException e) {e.printStackTrace();} catch (InternalException e) {e.printStackTrace();} catch (InvalidKeyException e) {e.printStackTrace();} catch (InvalidResponseException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();} catch (NoSuchAlgorithmException e) {e.printStackTrace();} catch (ServerException e) {e.printStackTrace();} catch (XmlParserException e) {e.printStackTrace();}}/*** @description: 根据filename获取文件访问地址* @dateTime: 2021/5/17 11:28*/public String getUrl(String objectName, int time, TimeUnit timeUnit) {String url = null;try {url = minioClient.getPresignedObjectUrl(GetPresignedObjectUrlArgs.builder().method(Method.GET).bucket(configuration.getBucketName()).object(objectName).expiry(time, timeUnit).build());} catch (ErrorResponseException e) {e.printStackTrace();} catch (InsufficientDataException e) {e.printStackTrace();} catch (InternalException e) {e.printStackTrace();} catch (InvalidKeyException e) {e.printStackTrace();} catch (InvalidResponseException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();} catch (NoSuchAlgorithmException e) {e.printStackTrace();} catch (XmlParserException e) {e.printStackTrace();} catch (ServerException e) {e.printStackTrace();}return url;}}
简单说明：
-
使用MultipartFile接收前端文件流，再上传到minio。 -
构建一个formData的签名数据，给前端，让前端之前上传到minio。 -
构建一个可以上传的临时URL给前端，前端通过携带文件请求该URL进行上传。 -
使用filename请求服务端获取临时访问文件的URL。（最长时间为7 天，想要永久性访问，需要其他设置，这里不做说明。）
下面展示页面html，使用的是VUE+element-ui进行渲染。

页面的效果就如上图所示。
可以分别体验不同的实现效果。
以上就是使用springboot搭建基于minio的高性能存储服务的全部步骤了。
