两种方式：1.自定义样式导出 2.根据模板导出
1.自定义设置样式导出PPT
public static void main(String[] args) throws IOException {
XMLSlideShow ppt = new XMLSlideShow();
// 创建幻灯片
XSLFSlide slide = ppt.createSlide();
// 创建文本框
XSLFTextBox textBox = slide.createTextBox();
// x y设置距离 w h 设置大小
textBox.setAnchor(new Rectangle2D.Double(30,0, 600, 50));
// 设置文本框的内容
textBox.addNewTextParagraph().addNewTextRun().setText("姓名");
// 创建文本框
XSLFTextBox textBox1 = slide.createTextBox();
// x y设置距离 w h 设置大小
textBox1.setAnchor(new Rectangle2D.Double(30,50, 600, 50));
// 设置文本框的内容
textBox1.addNewTextParagraph().addNewTextRun().setText("年龄");
// 创建文本框
XSLFTextBox textBox11 = slide.createTextBox();
// x y设置距离 w h 设置大小
textBox11.setAnchor(new Rectangle2D.Double(250,50, 600, 50));
// 设置文本框的内容
textBox11.addNewTextParagraph().addNewTextRun().setText("性别");
// 创建文本框
XSLFTextBox textBox2 = slide.createTextBox();
// x y设置距离 w h 设置大小
textBox2.setAnchor(new Rectangle2D.Double(30,100, 600, 50));
// 设置文本框的内容
textBox2.addNewTextParagraph().addNewTextRun().setText("时间");
// 创建文本框
XSLFTextBox textBox22 = slide.createTextBox();
// x y设置距离 w h 设置大小
textBox22.setAnchor(new Rectangle2D.Double(250,100, 600, 50));
// 设置文本框的内容
textBox22.addNewTextParagraph().addNewTextRun().setText("地点");
// 创建文本框
XSLFTextBox textBox3 = slide.createTextBox();
// x y设置距离 w h 设置大小
textBox3.setAnchor(new Rectangle2D.Double(30,150, 600, 50));
// 设置文本框的内容
textBox3.addNewTextParagraph().addNewTextRun().setText("事件"
// 创建文本框
XSLFTextBox textBox33 = slide.createTextBox();
// x y设置距离 w h 设置大小
textBox33.setAnchor(new Rectangle2D.Double(250,150, 600, 50));
// 设置文本框的内容
textBox33.addNewTextParagraph().addNewTextRun().setText("备注");
// 插入图片
// 获取图片的file对象
File file = new File("C:\\图片.png");
// 获取字节流
byte[] bt = FileUtils.readFileToByteArray(file);
XSLFPictureData idx = ppt.addPicture(bt, PictureData.PictureType.PNG);
// 插入图片
XSLFPictureShape pic = slide.createPicture(idx);
pic.setAnchor(new Rectangle2D.Double(30,200,350,150));
// 写入ppt中
ppt.write(new FileOutputStream("输出PPT"+".pptx"));
}
2.根据模板，创建PPT内容

import org.apache.poi.xslf.usermodel.*;
import java.io.*;
import java.util.*;
/**
* 读取模板PPT生成新的PPT文件
*
* @author yilurong
* @version 1.0.0
* @since 2022/3/10 - 15:37
*/
public class RenderPowerPointTemplate extends BasePowerPointFileUtil {
/**
* 读取PPT模板
* @param powerPoint
* @param
* @throws IOException
*/
public static void renderPowerPointTemplateOfCertificate(InputStream powerPoint, List<WeekAnalyseModel> lists, String rankType) throws IOException, IllegalAccessException {
//List<WeekAnalyseModel>是我们项目自己定义的model，可改成其他业务的model
if(powerPoint == null) {
return;
}
//创建一个幻灯片
XMLSlideShow slideShow = new XMLSlideShow(powerPoint);
//从幻灯片中获取每个页
List slides = slideShow.getSlides();
//获取第一页数据
XSLFSlide slide = slideShow.getSlides().get(0);
//创建指定数量的模板页面
for (int i = 1; i < lists.size(); i++) {
copyPptPage(slide,slideShow,i);
slideShow.write(new FileOutputStream("model-copy.pptx"));
}
//遍历每一页PPT
for (int i = 0 ; i < slides.size() ; i++) {
//幻灯片布局，文本框，矩形框之类的，遍历一页PPT中的所有控件
List shapes = ((Slide)slides.get(i)).getShapes();
for (int j = 0 ; j < shapes.size() ; j++) {
Shape shape = (Shape) shapes.get(j);
RenderPowerPointTemplate.renderShapeAndPicture(shape, lists.get(i),rankType);
}
}
//新PPT的位置，file就是新的PPT文件
File file=new File(rankType+".pptx");
OutputStream outputStreams = new FileOutputStream(file);
slideShow.write(outputStreams);
// FileUpLoadUtil.T_THREAD_LOCAL.set(file.getAbsolutePath());
System.out.println("新文件的路径:"+file.getAbsolutePath());
}
public static XSLFSlide copyPptPage(XSLFSlide slide, XMLSlideShow ppt, int index) throws IOException {
List<XSLFShape> shapes = slide.getShapes();
//创建新的一页PPT
XSLFSlide slides = ppt.createSlide();
if (shapes.size() > 0) {
for (XSLFShape shape : shapes) {
slides.importContent(shape.getSheet());
}
}
//排序（在PPT中的第几页）
ppt.setSlideOrder(slides, index);
return slides;
}
}
3.内容实体类
import lombok.Data;
@Data
public class WeekAnalyseModel {
private String name;
private String pictureURL;
private String person;
}
4.测试代码：
public static void main(String[] args) throws Exception {
//载入数据
WeekAnalyseModel weekAnalyseModel=new WeekAnalyseModel();
weekAnalyseModel.setName("数据来源1");
weekAnalyseModel.setPerson("数据来源1");
weekAnalyseModel.setPictureURL("http://dev.itqu.net/1.jpg");
WeekAnalyseModel weekAnalyseModel2=new WeekAnalyseModel();
weekAnalyseModel2.setName("数据来源2");
weekAnalyseModel2.setPerson("数据来源2");
weekAnalyseModel2.setPictureURL("http://dev.itqu.net/2.jpg");
WeekAnalyseModel weekAnalyseModel3=new WeekAnalyseModel();
weekAnalyseModel3.setName("数据来源3");
weekAnalyseModel3.setPerson("数据来源3");
weekAnalyseModel3.setPictureURL("http://dev.itqu.net/3.jpg");
ArrayList arrayList=new ArrayList();
arrayList.add(weekAnalyseModel);
arrayList.add(weekAnalyseModel2);
arrayList.add(weekAnalyseModel3);
//载入模板ppt,创建模板副本
InputStream inputStream = new FileInputStream("model.pptx");
copyFile("model.pptx","model-copy.pptx");
InputStream inputStreamCopy = new FileInputStream("model-copy.pptx");
RenderPowerPointTemplate.renderPowerPointTemplateOfCertificate(inputStreamCopy,arrayList,"out");
}
private static void copyFile(String source, String copy) {
Path sourcePath = Paths.get(source);
Path destinationPath = Paths.get(copy);
try {
Files.copy(sourcePath, destinationPath,StandardCopyOption.REPLACE_EXISTING);
} catch (FileAlreadyExistsException e) {
// 目标文件已经存在
} catch (IOException e) {
// 发生了其他错误
e.printStackTrace();
}
