SpringBoot 搭建基于 MinIO 的高性能存储服务

1.什么是MinIO

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/

2.使用docker 搭建minio 服务

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：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：

 

 

 

 

3.下面开始搭建springboot 环境

 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：

<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: 10MB
      max-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/bPxRfiCYEXAMPLEKEY
    url: http://localhost:9000
    bucket-name: wdhcr
  thymeleaf:
    cache: false

创建minio的配置类:

@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。

@Component
public class MinioComp {
    @Autowired
    private MinioClient minioClient;
    @Autowired
    private MinioConfiguration configuration;

    /**
     * @description: 获取上传临时签名

     */
    public Map getPolicy(String fileName, ZonedDateTime time) {
        PostPolicy postPolicy = new PostPolicy(configuration.getBucketName(), time);
        postPolicy.addEqualsCondition("key", fileName);
        try {
            Map map = minioClient.getPresignedPostFormData(postPolicy);
            HashMap 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) {

        }
        return null;
    }

    /**

            minioClient.putObject(PutObjectArgs.builder()

                    .object(fileName)

        try {
            url = minioClient.getPresignedObjectUrl(GetPresignedObjectUrlArgs.builder()
                    .method(Method.GET)
                    .bucket(configuration.getBucketName())

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。）
