springboot整合minio
java后端指南 人气:0对象存储服务OSS(Object Storage Service)是一种海量、安全、低成本、高可靠的云存储服务,适合存放任意类型的文件。容量和处理能力弹性扩展,多种存储类型供选择,全面优化存储成本。
安装minio
1、进入官网:https://min.io/
我目前安装的是版本是:
在cmd窗口中,命令行进行minio.exe所在的文件夹,输入如下命令 server后面的地址是你图片上传之后的存储目录
minio.exe server E:\minio
因为这里api端口是9000,所以下面的yml需要配置9000端口
accessKey和secretKey需要根据启动的窗口上的值进行配置
bucketName这个需要自己创建
2、启动成功后,访问:127.0.0.1:9000/minio,可以进入到minio的控制台
我们可以在控制台创建bucketName,当然也可以用代码创建
create bucket
其实这个bucketName就是文件夹的意思,我们要把文件上传到哪个bucketName,就是要把文件上传到对应的目录下。
如果需要使用minio,他的服务一定要打开。
依赖
<!--minio--> <dependency> <groupId>io.minio</groupId> <artifactId>minio</artifactId> <version>8.0.3</version> </dependency>
yml配置
spring: # 配置文件上传大小限制 servlet: multipart: max-file-size: 200MB max-request-size: 200MB minio: endpoint: http://127.0.0.1:9000 accessKey: minioadmin secretKey: minioadmin bucketName: test
写配置类
注册minio客户端,以便在代码中使用客户端上传文件。
@Data @Component public class MinIoClientConfig { @Value("${minio.endpoint}") private String endpoint; @Value("${minio.accessKey}") private String accessKey; @Value("${minio.secretKey}") private String secretKey; /** * 注入minio 客户端 * @return */ @Bean public MinioClient minioClient(){ return MinioClient.builder() .endpoint(endpoint) .credentials(accessKey, secretKey) .build(); } }
工具类
实体类:
@Data public class ObjectItem { private String objectName; private Long size; }
/** * @description: minio工具类 * @version:3.0 */ @Component public class MinioUtilS { @Autowired private MinioClient minioClient; @Value("${minio.bucketName}") private String bucketName; /** * description: 判断bucket是否存在,不存在则创建 * * @return: void */ public void existBucket(String name) { try { boolean exists = minioClient.bucketExists(BucketExistsArgs.builder().bucket(name).build()); if (!exists) { minioClient.makeBucket(MakeBucketArgs.builder().bucket(name).build()); } } catch (Exception e) { e.printStackTrace(); } } /** * 创建存储bucket * @param bucketName 存储bucket名称 * @return Boolean */ public Boolean makeBucket(String bucketName) { try { minioClient.makeBucket(MakeBucketArgs.builder() .bucket(bucketName) .build()); } catch (Exception e) { e.printStackTrace(); return false; } return true; } /** * 删除存储bucket * @param bucketName 存储bucket名称 * @return Boolean */ public Boolean removeBucket(String bucketName) { try { minioClient.removeBucket(RemoveBucketArgs.builder() .bucket(bucketName) .build()); } catch (Exception e) { e.printStackTrace(); return false; } return true; } /** * description: 上传文件 * * @param multipartFile * @return: java.lang.String */ public List<String> upload(MultipartFile[] multipartFile) { List<String> names = new ArrayList<>(multipartFile.length); for (MultipartFile file : multipartFile) { String fileName = file.getOriginalFilename(); String[] split = fileName.split("\\."); if (split.length > 1) { fileName = split[0] + "_" + System.currentTimeMillis() + "." + split[1]; } else { fileName = fileName + System.currentTimeMillis(); } InputStream in = null; try { in = file.getInputStream(); minioClient.putObject(PutObjectArgs.builder() .bucket(bucketName) .object(fileName) .stream(in, in.available(), -1) .contentType(file.getContentType()) .build() ); } catch (Exception e) { e.printStackTrace(); } finally { if (in != null) { try { in.close(); } catch (IOException e) { e.printStackTrace(); } } } names.add(fileName); } return names; } /** * description: 下载文件 * * @param fileName * @return: org.springframework.http.ResponseEntity<byte [ ]> */ public ResponseEntity<byte[]> download(String fileName) { ResponseEntity<byte[]> responseEntity = null; InputStream in = null; ByteArrayOutputStream out = null; try { in = minioClient.getObject(GetObjectArgs.builder().bucket(bucketName).object(fileName).build()); out = new ByteArrayOutputStream(); IOUtils.copy(in, out); //封装返回值 byte[] bytes = out.toByteArray(); HttpHeaders headers = new HttpHeaders(); try { headers.add("Content-Disposition", "attachment;filename=" + URLEncoder.encode(fileName, "UTF-8")); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } headers.setContentLength(bytes.length); headers.setContentType(MediaType.APPLICATION_OCTET_STREAM); headers.setAccessControlExposeHeaders(Arrays.asList("*")); responseEntity = new ResponseEntity<byte[]>(bytes, headers, HttpStatus.OK); } catch (Exception e) { e.printStackTrace(); } finally { try { if (in != null) { try { in.close(); } catch (IOException e) { e.printStackTrace(); } } if (out != null) { out.close(); } } catch (IOException e) { e.printStackTrace(); } } return responseEntity; } /** * 查看文件对象 * @param bucketName 存储bucket名称 * @return 存储bucket内文件对象信息 */ public List<ObjectItem> listObjects(String bucketName) { Iterable<Result<Item>> results = minioClient.listObjects( ListObjectsArgs.builder().bucket(bucketName).build()); List<ObjectItem> objectItems = new ArrayList<>(); try { for (Result<Item> result : results) { Item item = result.get(); ObjectItem objectItem = new ObjectItem(); objectItem.setObjectName(item.objectName()); objectItem.setSize(item.size()); objectItems.add(objectItem); } } catch (Exception e) { e.printStackTrace(); return null; } return objectItems; } /** * 批量删除文件对象 * @param bucketName 存储bucket名称 * @param objects 对象名称集合 */ public Iterable<Result<DeleteError>> removeObjects(String bucketName, List<String> objects) { List<DeleteObject> dos = objects.stream().map(e -> new DeleteObject(e)).collect(Collectors.toList()); Iterable<Result<DeleteError>> results = minioClient.removeObjects(RemoveObjectsArgs.builder().bucket(bucketName).objects(dos).build()); return results; } }
控制器
@RestController @Slf4j public class MinioController { @Autowired private MinIoUtil minIoUtil; @Autowired private MinioUtilS minioUtilS; @Value("${minio.endpoint}") private String address; @Value("${minio.bucketName}") private String bucketName; @PostMapping("/upload") public Object upload(MultipartFile file) { List<String> upload = minioUtilS.upload(new MultipartFile[]{file}); return address+"/"+bucketName+"/"+upload.get(0); } }
