    public static void main(String[] args) {

        //加载Word文档
        Document document = new Document();
        document.loadFromFile("C:\\Users\\Administrator\\Desktop\\sample.docx");

        //获取第一个section
        Section section = document.getSections().get(0);

        //调用insertHeaderAndFooter方法插入页眉页脚到第一个section
        insertHeaderAndFooter(section);

        //保存文档
        document.saveToFile("output/HeaderAndFooter.docx", FileFormat.Docx);
    }

    private static void insertHeaderAndFooter(Section section) {

        //分别获取section的页眉页脚
        HeaderFooter header = section.getHeadersFooters().getHeader();
        HeaderFooter footer = section.getHeadersFooters().getFooter();

        //添加段落到页眉
        Paragraph headerParagraph = header.addParagraph();

        //插入图片到页眉的段落
        DocPicture headerPicture = headerParagraph.appendPicture("C:\\Users\\Administrator\\Desktop\\Logo.png");
        headerPicture.setHorizontalAlignment(ShapeHorizontalAlignment.Left);
        headerPicture.setVerticalOrigin(VerticalOrigin.Top_Margin_Area);

        text.getCharacterFormat().setFontName("Arial");
        text.getCharacterFormat().setFontSize(10);
        text.getCharacterFormat().setItalic(true);
        headerParagraph.getFormat().setHorizontalAlignment(HorizontalAlignment.Right);

        //设置文字环绕方式
        headerPicture.setTextWrappingStyle(TextWrappingStyle.Behind);

        //设置页眉段落的底部边线样式
        headerParagraph.getFormat().getBorders().getBottom().setBorderType(BorderStyle.Single);

        //添加段落到页脚
        Paragraph footerParagraph = footer.addParagraph();

        //添加Field_Page和Field_Num_Pages域到页脚段落，用于显示当前页码和总页数 
        footerParagraph.appendField("page number", FieldType.Field_Page);
        footerParagraph.appendText(" of ");
        footerParagraph.appendField("number of pages", FieldType.Field_Num_Pages);
        footerParagraph.getFormat().setHorizontalAlignment(HorizontalAlignment.Right);

        //设置页脚段落的顶部边线样式
        footerParagraph.getFormat().getBorders().getTop().setBorderType(BorderStyle.Single);
        footerParagraph.getFormat().getBorders().getTop().setLineWidth(1f);
    }
