非结构化数据库-MinIO基本集成

是什么

MinIO 是一个高性能的分布式对象存储服务，适合存储非结构化数据，如图片，音频，视频，日志等。对象文件最大可以达到5TB。

安装启动

mkdir -p  /usr/local/minio
cd /usr/local/minio# 下载安装包
wget https://dl.min.io/server/minio/release/linux-amd64/minio

下载完毕后：

在当前minio目录下，会出现一个minio文件

# 给予权限
chmod +x minio# 创建minio文件存储目录及日志目录
mkdir -p /usr/local/minio/data
mkdir -p /usr/local/minio/logs

然后在 /usr/local/minio/目录下，新建一个run.sh并编辑以下内容

vim run.sh，然后将以下内容保存到run.sh,并为其赋予执行权限chmod u+x run.sh

run.sh内容如下：

#!/bin/bash
export MINIO_ACCESS_KEY=minio
export MINIO_SECRET_KEY=minio123456
# nohup启动服务 指定文件存放路径 /root/data 还有设置日志文件路径 /root/minio/log
nohup ./minio server --address :9000 --console-address :9001 /usr/local/minio/data > /usr/local/minio/logs/minio.log 2>&1 &

启动minIO

# 启动minio服务
./run.sh
# 查看日志
tail -f /usr/local/minio/logs/minio.log

平台使用

地址：http://127.0.0.1:9000（注意开放对应端口9000、9001）【当端口 9000 用于连接到 API 时，MinIO 会自动将浏览器访问重定向到 MinIO 控制台9001。】

输入账号密码后，

创建bucket，名字随意，创建完成后服务器/usr/local/minio/data下也会创建这个文件目录

SpringBoot集成MinIO

1.添加依赖

            <dependency><groupId>io.minio</groupId><artifactId>minio</artifactId><version>8.4.1</version></dependency>

2.配置文件

spring:minio:endpoint: http://124.222.253.33:9000access-key: miniosecret-key: minio123456bucket-name: fileservlet:multipart: # 上传文件最大大小max-file-size: 1024MBmax-request-size: 1024MB

3.配置类创建客户端

@Data
@Component
@ConfigurationProperties(prefix = "spring.minio")
public class MinioConfig {private String endpoint;private String accessKey;private String secretKey;@Beanpublic MinioClient minioClient() {return MinioClient.builder().endpoint(endpoint).credentials(accessKey, secretKey).build();}
}

4.核心业务类

仅有一些基础操作

@Slf4j
@Service
public class FileService {@Autowiredprivate MinioClient minioClient;private static final String SEPARATOR = "/";@Value("${spring.minio.bucket-name}")private String bucketName;/*** 上传文件** @param file 文件对象* @param id   设备ID*/public void uploadFile(MultipartFile file, Long id) {try {// 创建bucketif (!minioClient.bucketExists(BucketExistsArgs.builder().bucket(bucketName).build())) {minioClient.makeBucket(MakeBucketArgs.builder().bucket(bucketName).build());}// 同名文件会进行覆盖String objectName = file.getOriginalFilename();@CleanupInputStream inputStream = file.getInputStream();minioClient.putObject(PutObjectArgs.builder().bucket(bucketName).object(id + SEPARATOR + objectName) // 多文件夹.stream(inputStream, file.getSize(), -1).contentType(file.getContentType()).build());} catch (Exception e) {log.error("文件上传失败！{}", e.getMessage());throw new RuntimeException("文件上传失败，请重新上传");}}/*** 删除文件** @param path 文件路径*/public void removeObject(String path) {try {minioClient.removeObject(RemoveObjectArgs.builder().bucket(bucketName).object(path).build());} catch (Exception e) {log.error("文件删除失败！{}", e.getMessage());throw new RuntimeException("文件删除失败，请重新删除");}}/*** 文件列表** @param id 设备ID*/public List<FileInfo> listFiles(Long id) {Iterable<Result<Item>> results = minioClient.listObjects(ListObjectsArgs.builder().bucket(bucketName).recursive(true).build());List<FileInfo> infos = new ArrayList<>();results.forEach(r -> {FileInfo info = new FileInfo();try {Item item = r.get();// 最多一层文件夹String path = item.objectName();int idx = path.indexOf(SEPARATOR);if (path.substring(0, idx).equals(id.toString())) {info.setPath(path);info.setFileName(path.substring(idx + 1));info.setSize(item.size());infos.add(info);}} catch (Exception e) {e.printStackTrace();}});return infos;}/*** 下载文件** @param response response* @param path     文件路径*/public void downFile(HttpServletResponse response, String path) {try {@CleanupOutputStream outputStream = response.getOutputStream();@CleanupInputStream inputStream = minioClient.getObject(GetObjectArgs.builder().bucket(this.bucketName).object(path).build());response.reset();String fileName = path.substring(path.indexOf(SEPARATOR) + 1);response.setHeader("Content-Disposition", "attachment;filename=" +URLEncoder.encode(fileName.substring(fileName.lastIndexOf(SEPARATOR) + 1), "UTF-8"));response.setContentType("application/octet-stream");response.setCharacterEncoding("UTF-8");FileCopyUtils.copy(inputStream, outputStream);} catch (Throwable e) {log.error("文件下载失败！{}", e.getMessage());throw new RuntimeException("文件下载失败，请重新下载");}}
}

controller

@RestController
public class FileController {@Autowiredprivate FileService fileService;@PostMapping("/upload")public String uploadFile(@RequestParam("file") MultipartFile file, Long id) {fileService.uploadFile(file, id);return "上传成功";}@GetMapping("/download")public String downloadFile(HttpServletResponse response, String path) {fileService.downFile(response, path);return "下载成功";}@DeleteMapping("/delete")public String deleteFile(String path) {fileService.removeObject(path);return "删除成功";}@GetMapping("/list")public List<FileInfo> listFiles(Long id) {return fileService.listFiles(id);}
}
