java - 对于使用 Apache POI 的 .docx 文件，run.getFontFamily() 返回 null

Question

我想逐段阅读 .docx 文件，并检查每个段落的字体系列、字体大小、边距、对齐方式、颜色等。这是我的 .docx 文件的示例:

这是我的代码:

FileInputStream fis = new FileInputStream("D:/test3.docx");
XWPFDocument docx = new XWPFDocument(fis);
List<XWPFParagraph> paragraphList = docx.getParagraphs();
for (int i = 0; i < paragraphList.size(); i++) {
            System.out.println("paragraph " + i + " is::    " + paragraphList.get(i).getText());
            for (XWPFRun run : paragraphList.get(i).getRuns()) {
                System.out.println("paragraph :: run text is::    " + run.text());
                System.out.println("paragraph :: run color is::    " + run.getColor());
                System.out.println("paragraph :: run font-famyly is::    " + run.getFontFamily()); //It always return null; why?
                System.out.println("paragraph :: run font-name is::    " + run.getFontName()); //It always return null; why?
                System.out.println("paragraph :: run text position is::    " + run.getTextPosition()); //It always return -1; why?
                System.out.println("paragraph :: run font-size is::    " + run.getFontSize());
                System.out.println("paragraph :: run IsBold::    " + run.isBold());
                System.out.println("paragraph :: run IsItalic::    " + run.isItalic());

            }}

但是 fontFamily(对于我选择的每个字体系列)、fontName、textPosition 始终为 null。我有另一个代码示例来执行此操作:

            XWPFStyles styles = docx.getStyles();
        for (int i = 0; i < paragraphList.size(); i++) {
            System.out.println("paragraph " + i + " styleID  is::    " + paragraphList.get(i).getStyleID());
            if (paragraphList.get(i).getStyleID() != null) {
                String styleid = paragraphList.get(i).getStyleID();
                XWPFStyle style = styles.getStyle(styleid);
                if (style != null) {
                    System.out.println("style name is::    " + style.getName());
                    if (style.getName().startsWith("heading")) {
                        System.out.println("This part of text is heading!!");
                    }
                }

            }
        }

但是除了标题之外，样式通常为空。

这里是使用 apache POI 从 style.xml 获取样式的示例代码。

     XWPFDocument docx;                                                 // Set the docx
       XWPFRun run;                                                    //get the required run
       String fontFamily= run.getFontFamily();
        if(fontFamily == null){                                         // When the font in the run is null check for the default fonts in styles.xml
            String styleID = run.getParagraph().getStyleID();
            XWPFStyle style = docx.getStyle(styleID);
            CTStyle ctStyle = style.getCTStyle();
            CTRPr ctrPr = ctStyle.getRPr();
            CTFonts ctFonts = ctrPr.getRFonts();
            if(ctFonts!= null){
                fontFamily = ctFonts.getAscii();               // Or you may getCs() , getAnsi() etc.
            }
//                        else {
//                            fontFamily = ctStyle.getPPr().getRPr().getRFonts().getAscii();
//                        }
//                        System.out.println();
        }
        return fontFamily;

希望这会有所帮助。
