编写一段java代码获取ppt内部动画

获取PPT内部动画可以使用Apache POI库来解析PPT文件，具体步骤如下：

1. 加载PPT文件，创建XMLSlideShow对象

FileInputStream fis = new FileInputStream("test.pptx");
XMLSlideShow ppt = new XMLSlideShow(fis);

2. 遍历PPT中的所有幻灯片，获取每页Slide对象

for (XSLFSlide slide : ppt.getSlides()) {
    // 处理每一页幻灯片
}

3. 遍历每个Slide对象中的所有动画，获取每个XSLFShape对象

for (XSLFShape shape : slide.getShapes()) {
    if (shape instanceof XSLFTextShape) {
        XSLFTextShape textShape = (XSLFTextShape) shape;
        for (XSLFTextParagraph para : textShape) {
            for (XSLFTextRun run : para) {
                // 处理文本框中的动画
            }
        }
    } else if (shape instanceof XSLFGroupShape) {
        XSLFGroupShape groupShape = (XSLFGroupShape) shape;
        for (XSLFShape subShape : groupShape.getShapes()) {
            // 处理组合形状中的动画
        }
    } else {
        // 处理其他形状中的动画
    }
}

4. 获取每个XSLFShape对象中的动画，使用XSLFAnimationPainter类来渲染动画效果

XSLFAnimationPainter painter = shape.getAnimationPainter();
if (painter != null) {
    painter.startAnimation();
    // 处理动画效果
}

完整的Java代码示例如下：

import java.io.FileInputStream;
import java.io.IOException;

import org.apache.poi.xslf.usermodel.XMLSlideShow;
import org.apache.poi.xslf.usermodel.XSLFShape;
import org.apache.poi.xslf.usermodel.XSLFTextParagraph;
import org.apache.poi.xslf.usermodel.XSLFTextRun;
import org.apache.poi.xslf.usermodel.XSLFGroupShape;
import org.apache.poi.xslf.usermodel.XSLFTextShape;
import org.apache.poi.xslf.usermodel.XSLFSlide;
import org.apache.poi.xslf.usermodel.XSLFAnimationPainter;

public class PPTAnimationReader {

    public static void main(String[] args) throws IOException {
        FileInputStream fis = new FileInputStream("test.pptx");
        XMLSlideShow ppt = new XMLSlideShow(fis);

        for (XSLFSlide slide : ppt.getSlides()) {
            for (XSLFShape shape : slide.getShapes()) {
                if (shape instanceof XSLFTextShape) {
                    XSLFTextShape textShape = (XSLFTextShape) shape;
                    for (XSLFTextParagraph para : textShape) {
                        for (XSLFTextRun run : para) {
                            XSLFAnimationPainter painter = run.getAnimationPainter();
                            if (painter != null) {
                                painter.startAnimation();
                                // 处理动画效果
                            }
                        }
                    }
                } else if (shape instanceof XSLFGroupShape) {
                    XSLFGroupShape groupShape = (XSLFGroupShape) shape;
                    for (XSLFShape subShape : groupShape.getShapes()) {
                        XSLFAnimationPainter painter = subShape.getAnimationPainter();
                        if (painter != null) {
                            painter.startAnimation();
                            // 处理动画效果
                        }
                    }
                } else {
                    XSLFAnimationPainter painter = shape.getAnimationPainter();
                    if (painter != null) {
                        painter.startAnimation();
                        // 处理动画效果
                    }
                }
            }
        }

        ppt.close();
        fis.close();
    }

}

这里只是一个简单的示例，具体的动画处理需要根据实际情况来进行修改和完善。
