什么是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
  • 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:

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。

推荐一个 Spring Boot 基础教程及实战示例:https://github.com/javastacks/spring-boot-best-practice

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>

另外,这份Spring Boot 学习笔记分享给你。

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。最新 Spring Boot 面试题整理好了,大家可以在Java面试库小程序在线刷题。

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;
