run.getFontFamily（）使用Apache POI为.docx文件返回null

I want to read a .docx file paragraph by paragraph and I want to check font-family, font-size, margin, alignment, color and etc. for each paragraph. This is an example of my .docx file:

我想逐段阅读.docx文件,我想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文件的一个例子:

And this is my code:

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());

            }}

But fontFamily(for each font-family that I choose), fontName, textPosition are always null. I have another code sample to do this :

但是fontFamily(对于我选择的每个字体系列),fontName,textPosition总是为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!!");
                    }
                }

            }
        }

but style is usually null except for headings.

但除标题外,样式通常为null。

Apache POI parses the document.xml part of a .docx file. When you do a run.getFontFamily(), it will return the font family only if it is present in the run properties of the run. Otherwise it will return null. For example, consider this sample run

Apache POI解析.docx文件的document.xml部分。当您执行run.getFontFamily()时,只有在运行的运行属性中存在字体系列时,它才会返回该字体系列。否则它将返回null。例如,请考虑此示例运行

<w:r>
    <w:rPr>
        <w:lang w:val="en-US"/>
    </w:rPr>
    <w:t>The quick brown fox jumps over the lazy dog.</w:t>
</w:r>

This does have its font family specified in the <w:rPr> run properties tag. In cases like this, you have to go up the hierarchy and see if the paragraph which has this run has a style. If even the <w:Pr> paragraph properties does not have a style, then the font family which is default to the document is applied. The document defaults are specified in the styles.xml file.

这确实在运行属性标记中指定了其字体系列。在这种情况下,您必须上升层次结构,看看具有此运行的段落是否具有样式。如果即使段落属性没有样式,也会应用默认为文档的字体系列。文档默认值在styles.xml文件中指定。

Here is a sample code to get the styles from the style.xml using apache POI.

下面是使用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;

Hope this would be helpfull.

希望这会有所帮助。

I get out that fonts which I wanted to check were not standard!! So, for another standard fonts, all of above code works perfect.

我知道我想检查的字体不是标准的!因此,对于另一种标准字体,以上所有代码都是完美的。
