• 运行

docker-compose  -f ./docker-compose-minio.yml -p minio  up -d --build

设置minio基本参数

• 登录http://localhost:9293/minio输入root 和password
• 点击右下角加号选择创建桶create buket
  

• 设置桶的权限

  
  

集成SpringBoot

• 引入依赖

        
            io.minio
            minio
            6.0.11
        

        
        
            commons-io
            commons-io
            2.6
        

• 配置文件

@Getter
@Setter
@ConfigurationProperties(prefix = "minio")
public class MinioProp {

    public static final String MINIO_BUCKET = "mxf";

    private String endpoint;//连接url
    private String accesskey;//用户名
    private String secretKey;//密码
}

    }

}

@RestController

        String orgfileName = file.getOriginalFilename();
        try {

        }
        return "上传失败";
    }

    @RequestMapping("/download/{fileName}")
