}

场景2：根据ppt模板导出ppt

注意：如果是springboot项目打成jar后不能使用ResourceUtils.getFile(" ") 来读取资源文件，只能使用：InputStream inputStream = getClass().getClassLoader().getResourceAsStream("static/zhmd.pptx");

public static void PptExportUtil() throws IOException {//读取模板pptSlideShow ppt = new XMLSlideShow(new FileInputStream(ResourceUtils.getFile("classpath:static/zhmd.pptx")));//提取文本信息List<XSLFSlide> slides = ppt.getSlides();//   SlideShow slideShow = copyPage(slides.get(1), ppt,2);for (XSLFSlide slide : slides) {List<XSLFShape> shapes = slide.getShapes();for(int i=0;i<shapes.size();i++){Rectangle2D anchor = shapes.get(i).getAnchor();if (shapes.get(i) instanceof XSLFTextBox) {XSLFTextBox txShape = (XSLFTextBox) shapes.get(i);if (txShape.getText().contains("{schemeName}")) {// 替换文字内容.用TextRun获取替换的文本来设置样式TextRun rt = txShape.setText(txShape.getText().replace("{schemeName}", "测试方案"));rt.setFontColor(Color.BLACK);rt.setFontSize(20.0);rt.setBold(true);rt.setFontFamily("微软雅黑");}else if (txShape.getText().contains("{time}")) {TextRun textRun = txShape.setText(txShape.getText().replace("{time}", "2019-1-19"));textRun.setFontColor(Color.BLACK);textRun.setFontSize(20.0);textRun.setFontFamily("微软雅黑");}   else if (txShape.getText().contains("{projectAdd}")) {TextRun textRun = txShape.setText(txShape.getText().replace("{projectAdd}", "成都市经江区"));textRun.setFontColor(Color.BLACK);textRun.setFontSize(16.0);textRun.setFontFamily("微软雅黑");} else if (txShape.getText().contains("{rzl}")) {TextRun textRun = txShape.setText(txShape.getText().replace("{rzl}", "90%"));textRun.setFontColor(Color.BLACK);textRun.setFontSize(16.0);textRun.setFontFamily("微软雅黑");}else if (txShape.getText().contains("{cg}")) {TextRun textRun = txShape.setText(txShape.getText().replace("{cg}", "30"));textRun.setFontColor(Color.BLACK);textRun.setFontSize(16.0);textRun.setFontFamily("微软雅黑");}else if (txShape.getText().contains("{mediaImg2}")) {byte[] bytes = IOUtils.toByteArray(new FileInputStream(ResourceUtils.getFile("classpath:static/ceshi4.jpg")));PictureData pictureData = ppt.addPicture(bytes, XSLFPictureData.PictureType.JPEG);XSLFPictureShape picture = slide.createPicture(pictureData);picture.setAnchor(anchor);}else if (txShape.getText().contains("{mediaImg1}")) {byte[] bytes = IOUtils.toByteArray(new FileInputStream(ResourceUtils.getFile("classpath:static/ceshi4.jpg")));PictureData pictureData = ppt.addPicture(bytes, XSLFPictureData.PictureType.JPEG);XSLFPictureShape picture = slide.createPicture(pictureData);picture.setAnchor(anchor);}else if(txShape.getText().contains("{projectImg}")){byte[] bytes = IOUtils.toByteArray(new FileInputStream(ResourceUtils.getFile("classpath:static/ceshi5.jpg")));PictureData pictureData = ppt.addPicture(bytes, XSLFPictureData.PictureType.JPEG);XSLFPictureShape picture = slide.createPicture(pictureData);picture.setAnchor(anchor);}}}}OutputStream outputStreams = new FileOutputStream("F:\\test2.pptx");ppt.write(outputStreams);}

/** * @return * @Author * @Description //TODO 复制ppt中的幻灯片 ,并设置幻灯片在ppt中的位置 * @Date 2019/1/24 11:16 * @Param slide：被复制的幻灯片，ppt：ppt对象， index：复制的ppt插入到第几页 */public static XSLFSlide copyPage(XSLFSlide slide, XMLSlideShow ppt, int index) throws IOException {    List<XSLFShape> shapes = slide.getShapes();    XSLFSlide slide2 = ppt.createSlide();    if (shapes.size() > 0) {        for (XSLFShape shape : shapes) {            slide2.importContent(shape.getSheet());        }    }    //排序（在PPT中的第几页）    ppt.setSlideOrder(slide2, index);    return slide2;}

public static void main(String[] args) { try { PptExportUtil(); System.out.println("执行完成！！！！！！！！！"); } catch (IOException e) { e.printStackTrace(); } }

注意：返回给浏览器是一个流对象，前端页面需要通过<a href=" " > 的形式访问或则 window.location.href='' " 访问

或者用axios 请求文件：

 axios({url: path + '/ppt/export' + '?access_token=' + getToken(),method: 'post',type: 'application/vnd.ms-powerpoint',params: {pushDate: this.changeDate,schemeId: val.id},responseType: 'blob'}).then(response => {const blob = new Blob([response.data])const fileName = val.schemeName + '.pptx'if ('download' in document.createElement('a')) { // 非IE下载const elink = document.createElement('a')elink.download = fileNameelink.style.display = 'none'elink.href = URL.createObjectURL(blob)document.body.appendChild(elink)elink.click()URL.revokeObjectURL(elink.href) // 释放URL 对象
          document.body.removeChild(elink)this.disable = false} else { // IE10+下载
          navigator.msSaveBlob(blob, fileName)this.disable = false}})

3：如果PPT模板中包含表格，怎么往表格中添加数据呢？？

 /*** @return* @Author* @Description //TODO 六福珠宝--往PPT中表格填充数据* @Date 2019/4/21 16:41* @Param*/public void insertExcelDataToPPt(XSLFSlide slide, XMLSlideShow ppt, List<Map> DataTable) throws IOException {List<List<Map>> subListMap = getSubListMap(DataTable, 10);int k = 1;int p = 1;for (int a = 0; a < subListMap.size(); a++) {int h=1;XSLFSlide slide1 = copyPage(slide, ppt, p);List<XSLFShape> shapes = slide1.getShapes();for (XSLFShape shape : shapes) {Rectangle2D rcn = shape.getAnchor();//ppt页中是否含有表格判断if (shape instanceof XSLFTable) {XSLFTable table = (XSLFTable) shape;table.setAnchor(rcn);for (int d = 0; d < subListMap.get(a).size(); d++) {XSLFTableRow tr = table.getRows().get(h);int cellSize = tr.getCells().size();for (int j = 0; j < cellSize; j++) {if (j == 0) {tr.getCells().get(j).setText(String.valueOf(k));} else if (j == 1) {String projectName = String.valueOf(subListMap.get(a).get(d).get("projectName"));tr.getCells().get(j).setText(projectName);} else if (j == 2) {String projectAdds = String.valueOf(subListMap.get(a).get(d).get("projectAdds"));tr.getCells().get(j).setText(projectAdds);} else if (j == 3) {String ddNum = String.valueOf(subListMap.get(a).get(d).get("ddNum"));tr.getCells().get(j).setText(ddNum);} else if (j == 4) {String sjNum = String.valueOf(subListMap.get(a).get(d).get("sjNum"));tr.getCells().get(j).setText(sjNum);}}k += 1;h+=1;}}}p+=1;}ppt.removeSlide(0);}

4：集合分割：

 /*** @return* @Author* @Description //TODO 集合分割* @Date 2019/1/24 16:48* @Param*/private List<List<Map>> getSubListMap(List list, int len) {List<List<Map>> listGroup = new ArrayList<List<Map>>();if (list.size() < len) {listGroup.add(list);return listGroup;}int listSize = list.size();//子集合的长度int toIndex = len;for (int i = 0; i < list.size(); i += len) {if (i + len > listSize) {toIndex = listSize - i;}List<Map> newList = list.subList(i, i + toIndex);listGroup.add(newList);}return listGroup;}
