文件转换，简简单单，pdf转word，不要去找收费的了，自己学了之后免费转，之后就复制粘贴就ok了

先上一个链接pdf转word文件转换

接口层

    @PostMapping("pdfToWord")

    public String  pdfToWord(@RequestParam("file") MultipartFile file) throws IOException {

        String fileName = FileExchangeUtil.pdfToWord(file.getInputStream(),file.getName());
        return fileName;

    }

方法层-----一个方法直接搞定

  /**
     * 只是单纯的文字转换，没有任何的格式
     *
     * @param inputStream 文件流
     * @return
     */
    public static String pdfToWord(InputStream inputStream, String fileName) {
        //创建一个堆系pdf对象
        PDDocument document = null;
        FileOutputStream outputStream = null;
        if (Objects.isNull(fileName)) {
            fileName = FileExchangeUtil.getRandomString();
        }
        try {
            document = PDDocument.load(inputStream);
            PDFTextStripper stripper = new PDFTextStripper();
            //获取文本内容
            String text = stripper.getText(document);
            //创建word文档
            XWPFDocument doc = new XWPFDocument();
            XWPFParagraph p = doc.createParagraph();
            XWPFRun r = p.createRun();
            r.setText(text);
            //保存word
            outputStream = new FileOutputStream(new File("./file/"+fileName + ".docx"));
            doc.write(outputStream);
        } catch (IOException e) {
            e.printStackTrace();
            try {
                outputStream.close();
            } catch (IOException ioException) {
                ioException.printStackTrace();
                return null;
            }
            return null;
        }
        return fileName;

    }

经得起实操，不要怪我没有整理最终生成的格式，实在有些东西不好搞，只能放放了
