按段落 读取 docx

    @SneakyThrows
    private void readDocx(MultipartFile file) {
        InputStream inputStream = file.getInputStream();
        XWPFDocument document = new XWPFDocument(inputStream);
      	// 读取段落
        List<XWPFParagraph> paragraphs = document.getParagraphs();
        List<WordFileInfo> infos = new ArrayList<>();
        for (XWPFParagraph paragraph : paragraphs) {
            String text = paragraph.getParagraphText();
        }

    }

按段落 读取 doc

    @SneakyThrows
    private void readDoc(MultipartFile file) {
        InputStream inputStream = file.getInputStream();
        HWPFDocument document = new HWPFDocument(inputStream);
        Range range = document.getRange();
        List<WordFileInfo> infos = new ArrayList<>();
        for (int i = 0; i < range.numParagraphs(); i++) {
            Paragraph paragraph = range.getParagraph(i);
            String text = paragraph.text();
        }
    }

读取 pdf

/**
     * 读取 pdf 文件内容
     *
     * @param inputStream
     * @return
     */
    private String readPDF(InputStream inputStream) {
        StringBuilder content = new StringBuilder();
        try {
            RandomAccessBuffer buffer = new RandomAccessBuffer(inputStream);
            PDFParser pdfParser = new PDFParser(buffer);
            pdfParser.parse();
            PDDocument document = pdfParser.getPDDocument();
            // 获取页码
            int pages = document.getNumberOfPages();
            PDFTextStripper stripper = new PDFTextStripper();
            // 设置按顺序输出
            stripper.setSortByPosition(true);
            stripper.setStartPage(1);
            stripper.setEndPage(pages);
            content.append(stripper.getText(document));
        } catch (Exception e) {
            e.printStackTrace();
        }
        return content.toString();

    }
