本文主要是介绍oss对zip包中的所有文件进行上传并且对每个获取文件md5值，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
上传zip包方法
public static List<String> uploadZipMultiFile(MultipartFile fileData) {List<String> urls = new ArrayList<>();ZipInputStream zip = new ZipInputStream(fileData.getInputStream(), Charset.forName("UTF-8"));ZipEntry fileEntry;String env = "resource/";while ((fileEntry = zip.getNextEntry()) != null) {if (!fileEntry.isDirectory()) {String filename = fileEntry.getName();String suffix = StringUtils.substringAfterLast(filename, ".");filename = env + filename;@Cleanup ByteArrayOutputStream byteArrayOutputStream=new ByteArrayOutputStream();byte[] byte_s=new byte[1024];int num;while((num=zip.read(byte_s,0,byte_s.length))>-1) {//通过read方法来读取文件内容byteArrayOutputStream.write(byte_s, 0, num);}byte[] byte_s_=byteArrayOutputStream.toByteArray();String md5 = DigestUtils.md5Hex(byte_s_);createFolder(env);uploadFile(filename,byte_s_);filename= filename+"?md5="+md5;if (StringUtils.contains(contentType(suffix), "image")) {urls.add(OSS_IMAGE_HOST + filename);} else {urls.add( OSS_HOST + filename);}}}zip.close();return urls;}/*** @param key* @param content 文件内容* @throws Exception*/private static void uploadFile(String key, byte[] content) throws Exception {ObjectMetadata objectMeta = new ObjectMetadata();objectMeta.setContentLength(content.length);@Cleanup InputStream input = new ByteArrayInputStream(content);client.putObject(OSS_BUCKET, key, input, objectMeta);}/*** 创建目录** @param path 目录结构，这个有要求必须是 "xxx/xxx/" 以目录名开头，/结尾* @throws IOException*/private static void createFolder(String path) throws IOException {if (folderCache.containsKey(path)) return;ObjectMetadata objectMeta = new ObjectMetadata();byte[] buffer = new byte[0];objectMeta.setContentLength(0);try (ByteArrayInputStream in = new ByteArrayInputStream(buffer)) {client.putObject(OSS_BUCKET, path, in, objectMeta);}folderCache.put(path, true);}
