        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();

}

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 = fileName

          elink.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;

    }
