Apache PDFBox是一个开源的Java库,用于创建和操作PDF文档。它提供了丰富的功能,包括创建、编辑、合并、拆分和转换PDF文件。
在使用Apache PDFBox添加HTML标记时,您可以按照以下步骤进行操作:
PDDocument document = new PDDocument();
PDPage page = new PDPage();
document.addPage(page);
PDPageContentStream contentStream = new PDPageContentStream(document, page);
contentStream.setFont(PDType1Font.HELVETICA, 12);
contentStream.beginText();
contentStream.newLineAtOffset(50, 700);
String htmlContent = "<h1>Hello, World!</h1>";
PDHtmlTextStripper stripper = new PDHtmlTextStripper();
stripper.setStartPage(1);
stripper.setEndPage(2);
stripper.writeText(document, contentStream, htmlContent);
contentStream.endText();
contentStream.close();
上述代码中,我们创建了一个新的页面,并定义了文本的字体和大小。然后,我们使用PDHtmlTextStripper类将HTML内容添加到PDF文档中。
document.save("path/to/save/document.pdf");

// Create a new PDF document
PDDocument document = new PDDocument();
// Create a new page
PDPage page = new PDPage(PDRectangle.A4);
document.addPage(page);
// Create a new content stream for the page
PDPageContentStream contentStream = new PDPageContentStream(document, page);
// Load the HTML content from file or any other source
String htmlContent = "<h1>Hello, World!</h1>";
// Create a font and set it to the content stream
contentStream.setFont(PDType1Font.HELVETICA_BOLD, 12);
// Set the position for the text
contentStream.beginText();
contentStream.newLineAtOffset(50, 700);
// Add the HTML content to the PDF
PDFOperator operator = new PDFOperator();
operator.setOperation("EMC");
COSDictionary dictionary = new COSDictionary();
dictionary.setItem("EMC", new PDRange(-1f, 1f));
operator.setParameters(dictionary);
contentStream.processOperator(operator);
InputStream inputStream = IOUtils.toInputStream(htmlContent, "UTF-8");
PDStream stream = new PDStream(document, inputStream);
contentStream.close();
document.save("path/to/save/document.pdf");
document.close();
System.out.println("PDF document created successfully!");
} catch (IOException e) {
e.printStackTrace();
}
}
}
请注意,上述代码中的路径path/to/save/document.pdf
应替换为您希望保存PDF文档的实际路径。
