SpringBoot + minio实现分片上传、秒传、续传功能

作者:TNT报社

MinIO是一个基于Go实现的高性能、兼容S3协议的对象存储,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,这篇文章主要介绍了SpringBoot + minio实现分片上传、秒传、续传,需要的朋友可以参考下

什么是minio

MinIO是一个基于Go实现的高性能、兼容S3协议的对象存储。它采用GNU AGPL v3开源协议,项目地址是https://github.com/minio/minio

引用官网:

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/

一. 使用docker 搭建minio 服务

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

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:

二. 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:

<!-- 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: 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;
    /**

    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) {
