java - 使用 java 无法在 Word 文档中获取页数

Question

我需要使用java获取word文件的页数。我使用 poi jar 3.11 和以下代码。当我使用下面的代码时，我能够获取 2003 格式的 Word 文档，但是在读取页数时，它会抛出错误，如下所示 “”

公共(public)类CreateDocumentFromScratch {

public static int pagesNo;

public static void main(String[] args) {
    XWPFDocument document = new XWPFDocument();

    XWPFParagraph Paragraph = document.createParagraph();
    Paragraph.setBorderBottom(Borders.SINGLE);
    Paragraph.setBorderTop(Borders.SINGLE);
    Paragraph.setBorderRight(Borders.SINGLE);
    Paragraph.setBorderLeft(Borders.SINGLE);
    Paragraph.setBorderBetween(Borders.SINGLE);

    XWPFRun Titleparagraph = Paragraph.createRun();
    Titleparagraph.setBold(true);
    Titleparagraph.setItalic(true);
    Titleparagraph.setFontFamily("Latha");
    Titleparagraph.setFontSize(10);
    Titleparagraph.setText("ஓட்டு எண்ணிக்கையில் புதிய முறை: முதல் முடிவு வெளியாக தாமதம் ஆகும்");

    XWPFRun Headlineparagraph = Paragraph.createRun();
    Headlineparagraph.setBold(true);
    Headlineparagraph.setItalic(true);
    Headlineparagraph.setFontFamily("Latha");
    Headlineparagraph.setFontSize(10);
    Headlineparagraph.setText("தமிழகத்தில் ஓட்டு எண்ணிக்கையின் போது புதிய முறை கடை பிடிக்கப்படுவதால், முதல் முடிவு வெளிவர தாமதம் ஆகும் என்று தலைமை தேர்தல் அதிகாரி பிரவீன்குமார் கூறினார்.");
    Headlineparagraph.addBreak();

    FileOutputStream outStream = null;
    try {
        outStream = new FileOutputStream("Sample.doc");
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }

    try {
        document.write(outStream);
        outStream.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }


    WordExtractor extractor = null;
    FileInputStream fis = null;
    try {
        fis = new FileInputStream("Sample.doc");
    } catch (FileNotFoundException ex) {
        Logger.getLogger(CreateDocumentFromScratch.class.getName()).log(Level.SEVERE, null, ex);
    }
    HWPFDocument documentextract = null;
    try {
        documentextract = new HWPFDocument(fis);
    } catch (IOException ex) {
        Logger.getLogger(CreateDocumentFromScratch.class.getName()).log(Level.SEVERE, null, ex);
    }
    extractor = new WordExtractor(documentextract);
    extractor = new WordExtractor(documentextract);
    String[] paragraphs = extractor.getParagraphText();

    int pageCount = 1;
    for (int i = 0; i < paragraphs.length; ++i) {
        if (paragraphs[i].indexOf("\f") >= 0) {
            ++pageCount;
        }
    }
    JOptionPane.showMessageDialog(null, "pageCount --> "+pagesNo);
}

}

将 WordExtractor 替换为 XWPFWordExtractor，将 HWPFDocument 替换为 XWPFDocument。您可以使用 documentextract.getParagraphs() 提取 XWPFParagraph 列表。

像这样:

List<XWPFParagraph> paragraphs = documentextract.getParagraphs();
int pageCount = 1;
for (XWPFParagraph par :paragraphs) {
    if (par.getText().indexOf("\f") >= 0) {
        ++pageCount;
    }
}
