Minio概念

1. MinIO 是在 GNU Affero 通用公共许可证 v3.0 下发布的高性能对象存储。它与 Amazon S3 云存储服务 api 兼容。使用 MinIO 为机器学习、分析和应用程序数据工作负载构建高性能基础架构。
2. MinIO是高性能对象存储，什么是对象存储（Object Storage Service）,对象存储是支持海量用户远程访问的无限容量廉价存储系统，即是存储系统。
3. 它由桶（bucket,对应windows下的文件夹），组成目录结构，桶中直接存放对象（Object,对应Windwos下的文件），桶中不能再创建桶，但是能创建文件夹。

MinIO下载安装启动

访问官网：https://docs.min.io/
进入官网点击右上角Download

下载

点击Windows下载服务端

安装

将MinIO.exe 拷贝到自己的目录下去,并创建一个data目录

启动

通过命令行启动Minio ：
minio server ./data

启动完成后，可以看到访问的路径：Http://127.0.0.1:9000

使用提供的账号密码进行登录

​ 账号：minioadmin

​ 密码：minioadmin

MinIO实现上传文件

导入Maven坐标

     io.minio     minio     8.4.3

在application文件添加配置

# MinIO配置minio:  endpoint: 127.0.0.1  port: 9000  accessKey: minioadmin  secreTKEy: minioadmin  secure: false  bucketName: "demo"  configDir: "/data/excel"

实现代码

@Data@Component@ConfigurationProperties(prefix = "minio")public class Minioconfig {    private final static String HTTP = "http://";    //endPoint是一个URL，域名，IPv4或者IPv6地址    private String endpoint;    //tcp/IP端口号    private int port;    //accessKey类似于用户ID，用于唯一标识你的账户    private String accessKey;    //secretKey是你账户的密码    private String secretKey;    //如果是true，则用的是https而不是http,默认值是true    private Boolean secure;    //默认存储桶    private String bucketName;}

public class ajaxResult extends HashMap{    private static final long serialVersionUID = 1L;        public static final String CODE_TAG = "code";        public static final String MSG_TAG = "msg";        public static final String DATA_TAG = "data";        public AjaxResult()    {    }        public AjaxResult(int code, String msg)    {        super.put(CODE_TAG, code);        super.put(MSG_TAG, msg);    }        public AjaxResult(int code, String msg, Object data)    {        super.put(CODE_TAG, code);        super.put(MSG_TAG, msg);        if (StringUtils.isNotNull(data))        {            super.put(DATA_TAG, data);        }    }        public static AjaxResult success()    {        return AjaxResult.success("操作成功");    }        public static AjaxResult success(Object data)    {        return AjaxResult.success("操作成功", data);    }        public static AjaxResult success(String msg)    {        return AjaxResult.success(msg, null);    }        public static AjaxResult success(String msg, Object data)    {        return new AjaxResult(HttpStatus.SUCCESS, msg, data);    }        public static AjaxResult error()    {        return AjaxResult.error("操作失败");    }        public static AjaxResult error(String msg)    {        return AjaxResult.error(msg, null);    }        public static AjaxResult error(String msg, Object data)    {        return new AjaxResult(HttpStatus.ERROR, msg, data);    }        public static AjaxResult error(int code, String msg)    {        return new AjaxResult(code, msg, null);    }}

@RestControllerpublic class CommonController extends BaseController {    private static final Logger log = LoggerFactory.getLogger(CommonController.class);    @Autowired    private ISysFileService fileService;        @PostMapping("/common/upload")    public AjaxResult uploadFile(MultipartFile file){        try{            // 上传文件路径            return fileService.upload(file);        }catch (Exception e){            return AjaxResult.error(e.getMessage());        }    }}

public interface ISysFileService {AjaxResult upload(MultipartFile file);}

@Service@Slf4jpublic class SysFileServiceImpl implements ISysFileService{@AutowiredMinioConfig minioConfig;@Overridepublic AjaxResult upload(MultipartFile file) {InputStream inputStream = null;//创建Minio的连接对象MinioClient minioClient = getClient();//获取存储桶String bucketName = minioConfig.getBucketName();try {inputStream = file.getInputStream();// Make bucketName bucket if not exist.boolean found =minioClient.bucketExists(BucketExistsArgs.builder().bucket(bucketName).build());if (!found) {// Make a new bucket called bucketName.minioClient.makeBucket(MakeBucketArgs.builder().bucket(bucketName).build());} else {log.info("Bucket " +"["+bucketName+ "]"+" already exists.");}//Uploads given stream as object in bucket.String oldFileName = file.getOriginalFilename();String objectName = new SimpleDateFORMat("yyyy/MM/dd/").format(new Date())+IdUtils.simpleUUID()+oldFileName.substring(oldFileName.lastIndexOf("."));minioClient.putObject(PutObjectArgs.builder().bucket(bucketName).object(objectName).stream(inputStream, file.getSize(), -1).contentType(file.getContentType()).build());AjaxResult ajax = AjaxResult.success();ajax.put("fileName", "/"+bucketName+"/"+objectName);ajax.put("url", "http://"+minioConfig.getEndpoint()+":"+minioConfig.getPort()+"/"+minioConfig.getBucketName()+"/"+objectName);return ajax;}catch(Exception e){e.printStackTrace();return AjaxResult.error("上传失败");}finally {//防止内存泄漏if (inputStream != null) {try {inputStream.close(); // 关闭流} catch (IOException e) {log.debug("inputStream close IOException:" + e.getMessage());}}}}private MinioClient getClient(){MinioClient minioClient =MinioClient.builder().endpoint("http://"+minioConfig.getEndpoint()+":"+ minioConfig.getPort()).credentials(minioConfig.getAccessKey(),minioConfig.getSecretKey()).build();return minioClient;}}

响应数据格式

{"msg":"操作成功","fileName":"/demo/2022/10/14/efcb6266efba42a4b35344181964be36.pdf","code":200,"url":"http://127.0.0.1:9000/demo/2022/10/14/efcb6266efba42a4b35344181964be36.pdf"}

到此，上传文件到MinIO服务器就完成了。
