1.没啥新技术,采用了POI jar包实现,在参考原有代码基础上,更进一步,同时一位置插入2个图片:一个印章图片,一个签字图片。考虑到印章图片一般为非透明,采用居于文字下方方式展示,签字一般为透明图片,采用浮于文字上方方式展现。

需要引用的POI如下所示:

<dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi-ooxml</artifactId>
            <version>3.15</version>
        </dependency>
        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>ooxml-schemas</artifactId>
            <version>1.3</version>
        </dependency>
        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi-ooxml-schemas</artifactId>
            <version>3.15</version>
        </dependency>
        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi-scratchpad</artifactId>
            <version>3.15</version>
        </dependency>

示例代码如下(非生产环境使用):

 public void  creatSealDocument()throws IOException,InvalidFormatException
    {

        XWPFParagraph currentParagraph = null;
        File fileTem = new File("d:\\关于在全市开展活动的通知.docx");
        InputStream iss = new FileInputStream(fileTem);
        XWPFDocument doc = new XWPFDocument(iss);

        List<XWPFParagraph> xwpfParagraphList = doc.getParagraphs();
        for (int i = 0; i < xwpfParagraphList.size(); i++) {
            XWPFParagraph x = xwpfParagraphList.get(i);
            List<CTBookmark> bookmarkList = x.getCTP().getBookmarkStartList();
            for (int j = 0; j < bookmarkList.size(); j++) {
                System.out.println(bookmarkList.get(j).getName());
                if (bookmarkList.get(j).getName().equals("sign")) {
                    currentParagraph = x;
                    break;
                }
            }
        }
        if (currentParagraph != null) {
            //添加印章图片
            XWPFRun run = currentParagraph.createRun();

            String imgFile1 = "d:\\t2.jpg";
            FileInputStream is1 = new FileInputStream(imgFile1);
            run.addPicture(is1, XWPFDocument.PICTURE_TYPE_JPEG, imgFile1, Units.toEMU(60), Units.toEMU(60));
            is1.close();

            CTDrawing drawing1 = run.getCTR().getDrawingArray(0);
            CTGraphicalObject graphicalobject1 = drawing1.getInlineArray(0).getGraphic();
            Random random = new Random();
            int number = random.nextInt(999) + 1;
            //拿到新插入的图片替换添加CTAnchor 设置浮动属性 删除inline属性
            CTAnchor anchor1 = getAnchorWithGraphic(graphicalobject1, "Seal" + number,
                    Units.toEMU(60), Units.toEMU(60),//图片大小
                    Units.toEMU(250), Units.toEMU(0), true);//相对当前段落位置及偏移
            drawing1.setAnchorArray(new CTAnchor[]{anchor1});//添加浮动属性
            drawing1.removeInline(0);//删除行内属性
            //添加签名图片
            run = currentParagraph.createRun();
            imgFile1 = "d:\\t1.jpg";
            FileInputStream is2 = new FileInputStream(imgFile1);
            run.addPicture(is2, XWPFDocument.PICTURE_TYPE_JPEG, imgFile1, Units.toEMU(60), Units.toEMU(60));
            is2.close();

            random = new Random();
            CTDrawing drawing2 = run.getCTR().getDrawingArray(0);
            CTGraphicalObject graphicalobject2 = drawing2.getInlineArray(0).getGraphic();
            number = random.nextInt(999) + 1;
            CTAnchor anchor2 = getAnchorWithGraphic(graphicalobject2, "Seal" + number,
                    Units.toEMU(60), Units.toEMU(40),//图片大小
                    Units.toEMU(300), Units.toEMU(-5), false);
            drawing2.setAnchorArray(new CTAnchor[]{anchor2});//添加浮动属性
            drawing2.removeInline(0);//删除行内属性

            doc.write(new FileOutputStream("d:\\关于在全市开展活动的通知2.docx"));
            iss.close();
        }
        doc.close();
    }

getAnchorWithGraphic函数代码:

public static CTAnchor getAnchorWithGraphic(CTGraphicalObject ctGraphicalObject,
                                                String deskFileName, int width, int height,
                                                int leftOffset, int topOffset, boolean behind) {
       
        String anchorXML =
                "<wp:anchor xmlns:wp=\"http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing\" "
                        + "simplePos=\"0\" relativeHeight=\"0\" behindDoc=\"" + ((behind) ? 1 : 0) + "\" locked=\"0\" layoutInCell=\"1\" allowOverlap=\"1\">"
                        + "<wp:simplePos x=\"0\" y=\"0\"/>"
                        + "<wp:positionH relativeFrom=\"column\">"
                        + "<wp:posOffset>" + leftOffset + "</wp:posOffset>"
                        + "</wp:positionH>"
                        + "<wp:positionV relativeFrom=\"paragraph\">"
                        + "<wp:posOffset>" + topOffset + "</wp:posOffset>" +
                        "</wp:positionV>"
                        + "<wp:extent cx=\"" + width + "\" cy=\"" + height + "\"/>"
                        + "<wp:effectExtent l=\"0\" t=\"0\" r=\"0\" b=\"0\"/>"
                        + "<wp:wrapNone/>"
                        + "<wp:docPr id=\"1\" name=\"Drawing 0\" descr=\"" + deskFileName + "\"/><wp:cNvGraphicFramePr/>"
                        + "</wp:anchor>";

        CTDrawing drawing = null;
        try {
            drawing = CTDrawing.Factory.parse(anchorXML);
        } catch (XmlException e) {
            e.printStackTrace();
        }
        CTAnchor anchor = drawing.getAnchorArray(0);
        anchor.setGraphic(ctGraphicalObject);
        return anchor;
    }

效果如下:
