我将Microsoft Word .docx文档上传到Sharepoint。在我的java代码中,我已将此文档下载到byte []中。好。现在,我想要的是处理这个byte []以获取XWPFDocument并能够将一些变量替换为文档。

拜托,有人可以帮帮我吗?

谢谢!

您可以使用XWPFDocument的构造函数中指定的InputStream(ByteArrayInputStream)从byte []读取XWPFDocument,您可以从XWPFDocument获取段落和运行。 之后,您可以进行如下编辑。

byte[] byteData = ....

// read as XWPFDocument from byte[]
XWPFDocument doc = new XWPFDocument(new ByteArrayInputStream(byteData));

int numberToPrint = 0;

// you can edit paragraphs
for (XWPFParagraph para : doc.getParagraphs()) {
    List<XWPFRun> runs = para.getRuns();

    numberToPrint++;

    for (XWPFRun run : runs) {

        // read text
        String text = run.getText(0);

        // edit text and update it
        run.setText(numberToPrint + " " + text, 0);
    }
}

// save it and you can get the updated .docx
FileOutputStream fos = new FileOutputStream(new File("updated.docx"));
doc.write(fos);

ByteArrayInputStream bis = new ByteArrayInputStream(bytebuffer);
POIXMLTextExtractor extractor = (POIXMLTextExtractor) ExtractorFactory.createExtractor(bis);
POIXMLDocument document = extractor.getDocument();

 if (document instanceof XWPFDocument) 
        XWPFDocument xDocument = (XWPFDocument) document;
