1.什么是MinIO
MinIO是根據GNU Affero通用公共許可證v3.0發布的高性能物件存盤，它與Amazon S3云存盤服務兼容，使用MinIO構建用于機器學習，分析和應用程式資料作業負載的高性能基礎架構，
官網地址：https://min.io/
檔案地址：https://docs.min.io/
2.使用docker 搭建minio 服務
2.1.GNU / Linux和macOS
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
2.2.windows
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：為用戶keyMINIO_ROOT_PASSWORD：為用戶密鑰
以上搭建的都是單機版的，想要了解分布式 的方式請查看官網檔案，
這就是在win的docker上運行的，
當啟動后在瀏覽器訪問 http://localhost:9000 就可以訪問minio的圖形化界面了，如圖所示：
3.下面開始搭建springboot 環境
初始化一個springboot專案大家都會，這里不多做介紹，
主要是介紹需要引入的依賴：
<!-- 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客戶端--> <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>
依賴可以官方檔案里找：https://docs.min.io/docs/java-client-quickstart-guide.html
下面介紹組態檔：
spring:
servlet:
multipart:
max-file-size: 10MB
max-request-size: 10MB
#minio配置
minio:
access-key: AKIAIOSFODNN7EXAMPLE #key就是docker初始化是設定的，密鑰相同
secret-key: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
url: http://localhost:9000
bucket-name: wdhcr
thymeleaf:
cache: false
創建minio的配置類:
@Configuration @ConfigurationProperties(prefix = "spring.minio") @Data public class MinioConfiguration { private String accessKey; private String secretKey; private String url; private String bucketName; @Bean public MinioClient minioClient() { return MinioClient.builder() .endpoint(url) .credentials(accessKey, secretKey) .build(); } }
使用配置屬性系結進行引數系結,并初始化一個minio client物件放入容器中，
下面就是我封裝的minio client 操作minio的簡單方法的組件，
@Component public class MinioComp { @Autowired private MinioClient minioClient; @Autowired private MinioConfiguration configuration; /** * @description: 獲取上傳臨時簽名 * @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: 獲取上傳檔案的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: 上傳檔案 * @dateTime: 2021/5/13 14:17 */ public void upload(MultipartFile file, String fileName) { // 使用putObject上傳一個檔案到存盤桶中， 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: 根據filename獲取檔案訪問地址 * @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; } }
簡單說明：
- 使用MultipartFile接收前端檔案流，再上傳到minio，
- 構建一個formData的簽名資料，給前端，讓前端之前上傳到minio，
- 構建一個可以上傳的臨時URL給前端，前端通過攜帶檔案請求該URL進行上傳，
- 使用filename請求服務端獲取臨時訪問檔案的URL，（最長時間為7 天，想要永久性訪問，需要其他設定，這里不做說明，）
下面展示頁面html，使用的是VUE+element-ui進行渲染，

可以分別體驗不同的實作效果，
以上就是使用springboot搭建基于minio的高性能存盤服務的全部步驟了，
