使用POI進行word標簽替換及添加印章及簽名圖片方案

1.POI引用：

　　　　 <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>

2.替換段落標簽

功能代碼如下：

        File fileTem = new File(officeWordPath() + File.separator + tMobileWordSign.getWordPath());
        InputStream iss = new FileInputStream(fileTem);
        XWPFDocument doc = new XWPFDocument(iss);
        DateFormat dateFormat = new SimpleDateFormat("yyyy 年 MM 月 dd 日");

        List<XWPFParagraph> xwpfParagraphList = doc.getParagraphs();
        //基本內容替換
        for (XWPFParagraph xwpfParagraph : xwpfParagraphList) {
           
　　　　　　  CTP ctp = xwpfParagraph.getCTP();

            for (int dwI = 0; dwI < ctp.sizeOfBookmarkStartArray(); dwI++) {
                CTBookmark bookmark = ctp.getBookmarkStartArray(dwI);
                if (bookmark.getName().equals("year")) {

                    XWPFRun run = xwpfParagraph.createRun();
                    run.setText(dateFormat.format(tMobileWordSign.getSignDate()));

                    Node firstNode = bookmark.getDomNode();
                    Node nextNode = firstNode.getNextSibling();
                    while (nextNode != null) {
                        // 循環查找結束符
                        String nodeName = nextNode.getNodeName();
                        if (nodeName.equals(BOOKMARK_END_TAG)) {
                            break;
                        }
                        // 刪除中間的非結束節點，即刪除原書簽內容
                        Node delNode = nextNode;
                        nextNode = nextNode.getNextSibling();

                        ctp.getDomNode().removeChild(delNode);
                    }
                    if (nextNode == null) {
                        // 始終找不到結束標識的，就在書簽前面添加
                        ctp.getDomNode().insertBefore(run.getCTR().getDomNode(), firstNode);
                    } else {
                        // 找到結束符，將新內容添加到結束符之前，即內容寫入bookmark中間
                        ctp.getDomNode().insertBefore(run.getCTR().getDomNode(), nextNode);
                    }
                }
            }
        }

3.添加印章及簽名圖片

在參考原有代碼基礎上，更進一步，同時一位置插入2個圖片：一個印章圖片，一個簽字圖片。考慮到印章圖片一般為非透明，采用居於文字下方方式展示，簽字一般為透明圖片，采用浮於文字上方方式展現。

示例代碼如下（非生產環境使用）：

 　　public void  creatSealDocument()throws IOException,InvalidFormatException
    {

        XWPFParagraph currentParagraph = null;
        File fileTem = new File("d:\\關於在全市開展活動的通知.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) {
            //添加印章圖片
            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;
            //拿到新插入的圖片替換添加CTAnchor 設置浮動屬性 刪除inline屬性
            CTAnchor anchor1 = getAnchorWithGraphic(graphicalobject1, "Seal" + number,
                    Units.toEMU(60), Units.toEMU(60),//圖片大小
                    Units.toEMU(250), Units.toEMU(0), true);//相對當前段落位置及偏移
            drawing1.setAnchorArray(new CTAnchor[]{anchor1});//添加浮動屬性
            drawing1.removeInline(0);//刪除行內屬性
            //添加簽名圖片
            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),//圖片大小
                    Units.toEMU(300), Units.toEMU(-5), false);
            drawing2.setAnchorArray(new CTAnchor[]{anchor2});//添加浮動屬性
            drawing2.removeInline(0);//刪除行內屬性

            doc.write(new FileOutputStream("d:\\關於在全市開展活動的通知2.docx"));
            iss.close();
        }
        doc.close();
    }

getAnchorWithGraphic函數代碼：

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：

4.輸出word代碼

　　　　 String fileName = URLEncoder.encode("關於在全市開展活動的通知", "UTF8") + ".docx";
        String reqBrowser = request.getHeader("User-Agent");
        if (reqBrowser.toLowerCase().indexOf("firefox") > 0) {
            fileName = new String("關於在全市開展活動的通知".getBytes("UTF-8"), "ISO8859-1") + ".docx";
        }
        String headStr = "attachment; filename=\"" + fileName + "\"";
        response.reset();
        response.setContentType("application/vnd.openxmlformats-officedocument.wordprocessingml.document");
        response.setHeader("Content-Disposition", headStr);
        OutputStream out = response.getOutputStream();
        out.flush();
        doc.write(out);
        out.flush();
        doc.close();
        out.close();
