SpringBoot 搭建基于 minio 的高性能存儲服務
什么是minio
引用官網(wǎng)：
MinIO是根據(jù)GNU Affero通用公共許可證v3.0發(fā)布的高性能對象存儲。它與Amazon S3云存儲服務兼容。使用MinIO構建用于機器學習，分析和應用程序數(shù)據(jù)工作負載的高性能基礎架構。
官網(wǎng)地址：
https://min.io/
文檔地址：
https://docs.min.io/
一. 使用docker 搭建minio 服務。
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
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(wǎng)文檔。
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：
二. 下面開始搭建springboot 環(huán)境
初始化一個springboot項目大家都會，這里不多做介紹。
主要是介紹需要引入的依賴：
??<dependency>
????????????<groupId>org.springframework.bootgroupId>
????????????<artifactId>spring-boot-starter-thymeleafartifactId>
????????dependency>
?????????<dependency>
????????????<groupId>io.miniogroupId>
????????????<artifactId>minioartifactId>
????????????<version>8.2.1version>
????????dependency>
?????????<dependency>
????????????<groupId>org.projectlombokgroupId>
????????????<artifactId>lombokartifactId>
????????????<optional>trueoptional>
????????dependency>
依賴可以官方文檔里找：https://docs.min.io/docs/java-client-quickstart-guide.html
下面介紹配置文件：
spring:
??servlet:
????multipart:
??????max-file-size:?10MB
??????max-request-size:?10MB
#minio配置
??minio:
????access-key:?AKIAIOSFODNN7EXAMPLE??????#key就是docker初始化是設置的，密鑰相同
????secret-key:?wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
????url:?http://localhost:9000
????bucket-name:?wdhcr
??thymeleaf:
????cache:?false
創(chuàng)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();
????}
}
使用配置屬性綁定進行參數(shù)綁定,并初始化一個minio client對象放入容器中。
下面就是我封裝的minio client 操作minio的簡單方法的組件。

簡單說明：
使用MultipartFile接收前端文件流，再上傳到minio。 構建一個formData的簽名數(shù)據(jù)，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，前端通過攜帶文件請求該URL進行上傳。 使用filename請求服務端獲取臨時訪問文件的URL。（最長時間為7 天，想要永久性訪問，需要其他設置，這里不做說明。）

以上就是使用springboot搭建基于minio的高性能存儲服務的全部步驟了。
