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ppt SlideShow 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); }
/**

* @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());
// }
// }
slide2.importContent(slide);
//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 = 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; }
