Java转换html为图片，图片嵌入pdf/word

要将HTML转换为图片并嵌入PDF或Word文档，你可以使用Java的库，如Apache PDFBox和Apache POI。以下是一个简单的例子，演示如何使用这些库将HTML转换为图片并嵌入PDF文档。

首先，确保你的项目中包含了以下依赖（对于Maven项目，在pom.xml中添加）：

<!-- PDFBox -->
<dependency>
    <groupId>org.apache.pdfbox</groupId>
    <artifactId>pdfbox</artifactId>
    <version>2.0.24</version>
</dependency>
 
<!-- Apache POI for Word processing -->
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>5.2.3</version>
</dependency>

以下是将HTML转换为图片并嵌入PDF的Java代码示例：

        // 创建一个PDF文档
        PDDocument document = new PDDocument();
        PDPage page = new PDPage(PDRectangle.A4);
        document.addPage(page);
 
        // 将HTML转换为图片
        BufferedImage image = convertHtmlToImage("http://example.com");
 
        // 将图片转换为PDF图像对象
        PDImageXObject pdImage = PDImageXObject.createFromBitmap(document, image, "Image");
 
        // 在PDF中添加图片
        PDPageContentStream contentStream = new PDPageContentStream(document, page);
        contentStream.drawImage(pdImage, 5
