什麼是minio

引用官網：

MinIO是根據GNU Affero通用公共許可證v3.0發佈的高性能對象存儲。它與Amazon S3雲存儲服務相容。使用MinIO構建用於機器學習，分析和應用程式數據工作負載的高性能基礎架構。

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key
MINIO_ROOT_PASSWORD：為用戶密鑰

以上搭建的都是單機版的。想要瞭解分散式的方式請查看官網文檔。

這就是在win的docker上運行的。

當啟動後在瀏覽器訪問http://localhost:9000就可以訪問minio的圖形化界面了，如圖所示：

二. 下麵開始搭建springboot 環境

初始化一個springboot項目大家都會，這裡不多做介紹。

推薦一個 Spring Boot 基礎教程及實戰示例：https://github.com/javastacks/spring-boot-best-practice

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>

依賴可以官方文檔里找：https://docs.min.io/docs/java-client-quickstart-guide.html

下麵介紹配置文件：

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綁定,並初始化一個minio client對象放入容器中。

下麵就是我封裝的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;

    /**

    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) {

        return url;
    }
}

簡單說明：

使用MultipartFile接收前端文件流，再上傳到minio。
構建一個formData的簽名數據，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，這裡不做說明。）
