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(403 Forbidden);
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(403 Forbidden);
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(403 Forbidden);
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(403 Forbidden);
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(403 Forbidden);
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());// }// }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: Virtue Digital Indonesia
},
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 - Pay Per Click Platform()
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;
}
