java poi 生成docx插入頁腳

代碼如下

/**
     * 設置頁腳的字體樣式
     *
     * @param r1 段落元素
     */
    private void setXWPFRunStyle(XWPFRun r1,String font,int fontSize) {
        r1.setFontSize(fontSize);
        CTRPr rpr = r1.getCTR().isSetRPr() ? r1.getCTR().getRPr() : r1.getCTR().addNewRPr();
        CTFonts fonts = rpr.isSetRFonts() ? rpr.getRFonts() : rpr.addNewRFonts();
        fonts.setAscii(font);
        fonts.setEastAsia(font);
        fonts.setHAnsi(font);
    }

 注意  doc 爲  XWPFDocument doc = null
