一、运用场景
获取本地压缩包#xff0c;解压后根据文件名称及类型#xff0c;对读取的文件内容进行业务处理。
二、POM文件依赖

1、控制层方法
GetMapping(value /localZipFile)public Result localZipFile(){String filePath C:\\Users\\Administrator\\Desktop\\11.zip;ListString list new ArrayList();try {ZipFile zipFile new ZipFile(filePath);Enumeration? extends ZipEntry entries zipFile.getEntries();//获取zip包下文件名while (entries.hasMoreElements()) {list.add(entries.nextElement().getName());}String packFileStr C:\\Users\\Administrator\\Desktop\\zip;File file new File(filePath);String packFilePath packFileStr File.separator;//解压到指定路径UnPackeUtil.unPackZip(file, null,packFilePath);File readFileDir new File(packFilePath);ListString strings new ArrayList();//获取文件夹下文件集合File[] files readFileDir.listFiles();for (File file1 : files) {String savePath MeFileUtils.uploadLocal(file1,);FileInputStream inputStream new FileInputStream(file1);String fileExtension MeFileUtils. getFileExtension(file1.getName());//返回读取的文件内容String fileContent MeFileUtils.readGsFile(inputStream,fileExtension,file1);strings.add(savePath);strings.add(fileContent);}return Result.OK(strings);} catch (IOException e) {e.printStackTrace();return Result.error(e.getMessage());}2、MeFileUtils工具类
//上传
public class MeFileUtils{public static String uploadLocal(File file,String bizPath){try {String ctxPath uploadpath;String fileName null;File file new File(ctxPath File.separator bizPath File.separator );if (!file.exists()) {file.mkdirs();// 创建文件根目录}// 获取文件名String orgName mf.getName();orgName CommonUtils.getFileName(orgName);if(orgName.indexOf(.)!-1){fileName orgName.substring(0, orgName.lastIndexOf(.)) _ System.currentTimeMillis() orgName.substring(orgName.lastIndexOf(.));}else{fileName orgName _ System.currentTimeMillis();}String savePath file.getPath() File.separator fileName;File savefile new File(savePath);FileCopyUtils.copy(mf, savefile);String dbpath null;if(oConvertUtils.isNotEmpty(bizPath)){dbpath bizPath File.separator fileName;}else{dbpath fileName;}if (dbpath.contains(\\)) {dbpath dbpath.replace(\\, /);}return dbpath;} catch (IOException e) {log.error(e.getMessage(), e);}return ;}//获取文件名public String getFileExtension(String filename) {int dotIndex filename.lastIndexOf(.);if (dotIndex 0 dotIndex filename.length() - 1) {return filename.substring(dotIndex 1).toLowerCase();}return ;}//获取文件内容public String readGsFile(FileInputStream inputStream,String fileExtension,File txtFile) {try {if (fileExtension.equalsIgnoreCase(doc) || fileExtension.equalsIgnoreCase(docx)) {// 处理Word文档XWPFDocument document new XWPFDocument(inputStream);// 读取每个段落的文本内容StringBuilder content new StringBuilder();for (XWPFParagraph paragraph : document.getParagraphs()) {for (XWPFRun run : paragraph.getRuns()) {content.append(run.text());}}// 关闭文档document.close();return content.toString();}else if(fileExtension.equalsIgnoreCase(txt)){StringBuffer buffer new StringBuffer();// 创建Scanner对象来读取文件内容Scanner scanner new Scanner(txtFile);// 逐行读取文件内容并输出while (scanner.hasNextLine()) {String line scanner.nextLine();System.out.println(line);buffer.append(line).append(,);}// 关闭Scanner对象scanner.close();return buffer.toString();} else if (fileExtension.equalsIgnoreCase(xls) || fileExtension.equalsIgnoreCase(xlsx)) {// 处理Excel文档XSSFWorkbook workbook new XSSFWorkbook(inputStream);return ;} else if (fileExtension.equalsIgnoreCase(pdf)) {// 处理PDF文档PDDocument document PDDocument.load(inputStream);// 创建 PDFTextStripper 对象PDFTextStripper textStripper new PDFTextStripper();// 读取文档内容String content textStripper.getText(document);document.close();return content;}else if (fileExtension.equalsIgnoreCase(jpg) || fileExtension.equalsIgnoreCase(png)) {// 处理图片try {// 调用OCR工具类识别文件内容String result BaiduOCRUtil.recognizeFile(txtFile.getAbsolutePath());return result;} catch (Exception e) {e.printStackTrace();return ;}} else {// 其他文件格式inputStream.close();return ;}} catch (IOException e) {e.printStackTrace();return ;}}
}3、BaiduOCRUtil工具类
public class BaiduOCRUtil {private static final String APP_ID ;private static final String API_KEY ;private static final String SECRET_KEY ;public static String recognizeFile(String filePath) {AipOcr client new AipOcr(APP_ID, API_KEY, SECRET_KEY);// 设置可选参数HashMapString, String options new HashMap();options.put(language_type, CHN_ENG);options.put(detect_direction, true);options.put(detect_language, true);options.put(probability, true);// 调用百度云OCR服务识别文件内容JSONObject response client.basicGeneral(filePath, options);// 解析识别结果StringBuilder result new StringBuilder();JSONArray wordsArray response.getJSONArray(words_result);for (int i 0; i wordsArray.length(); i) {JSONObject wordsObject wordsArray.getJSONObject(i);String words wordsObject.getString(words);result.append(words).append(\n);}return result.toString();}
