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

}

2.模板处理

import com.oppo.ipd.plm.mechanical.web.structure.PPTExport.bean.WeekAnalyseModel;
import org.apache.poi.sl.usermodel.Shape;
import org.apache.poi.sl.usermodel.Slide;
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();
        }
    }
