简介

MinIO Java Client SDK提供简单的API来访问任何与Amazon S3兼容的对象存储服务。
官方demo: https://github.com/minio/minio-java
官方文档：https://docs.min.io/docs/java-client-api-reference.html
普通Java集成

第一步

引入pom.xml依赖。

<!-- MinIO 依赖 -->
<dependency>
    <groupId>io.minio</groupId>
    <artifactId>minio</artifactId>

    <artifactId>okhttp</artifactId>
    <version>4.9.0</version>

第二步

SpringBoot集成

第一步

引入pom.xml依赖。

<!-- MinIO 依赖 -->
<dependency>
    <groupId>io.minio</groupId>
    <artifactId>minio</artifactId>
    <version>8.3.3</version>
</dependency>
<dependency>
    <groupId>com.squareup.okhttp3</groupId>
    <artifactId>okhttp</artifactId>
    <version>4.9.0</version>
</dependency>

第二步

配置application.yml文件

minio:
  endpoint: http://192.168.1.86:90
  username: admin
  password: 12345678
  bucketname: bucket02

第三步

增加MinIOConfig配置类。

package com.example.demo.minio;

import io.minio.MinioClient;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * @author ：Mall

public class MinIOConfig {
    //MinIO的API地址
    @Value("${minio.endpoint}")
    private String endpoint;
    @Value("${minio.username}")
    private String username;
    @Value("${minio.password}")
    private String password;

    @Bean
    public MinioClient minioClient() {
        return MinioClient.builder().endpoint(endpoint).credentials(username, password).build();
    }
}

第四步

增加MinIOUtil工具类

package com.example.demo.minio;

import io.minio.*;
import io.minio.errors.*;
import io.minio.messages.Bucket;
import io.minio.messages.Item;
import org.springframework.beans.factory.annotation.Autowired;
