我必须创建输出发票 PDF 文件的流程。我们找不到比创建 html 文件(使用 thymeleaf)并使用某种帮助程序(例如 itextpdf )将其格式化为 PDF 文件更好的解决方案。但我鼓励了一些问题，因为我无法包含 css 文件和图像。有没有更好的解决方案(免费)来处理它？或者你可以帮我吗？我将包括我的java代码。谢谢!

@Service
public class InvoiceTemplateHelper {

private final TemplateEngine templateEngine;
private ServletContext ctx;
private HttpServletRequest request;

@Autowired
public InvoiceTemplateHelper(TemplateEngine templateEngine, ServletContext ctx, HttpServletRequest request) {
    this.templateEngine = templateEngine;
    this.ctx = ctx;
    this.request = request;
}

public String getHTMLInvoice() throws InvoiceCreationException {
    WebContext context = new WebContext(request, null, ctx);
    context.setVariable("invoiceTitle", "INVOICE/010101");

    String body = templateEngine.process("invoice", context);
    convertToPDF(body);
    return body;
}

public void convertToPDF(String body) throws InvoiceCreationException {
    try{
        Document document = new Document(PageSize.A4);
        PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("invoice.pdf"));
        document.open();
        InputStream is = new ByteArrayInputStream(body.getBytes());
        XMLWorkerHelper.getInstance().parseXHtml(writer, document, is);
        document.close();
    } catch (IOException e){
        //TODO MESSAGE FOR EXCEPTION
        throw new InvoiceCreationException();
    } catch ( DocumentException e){
        //TODO MESSAGE FOR EXCEPTION
        throw new InvoiceCreationException();
    }
}
}

以及带有示例样式和数据的虚拟 html 文件。

最佳答案

看看 pdfHtml。这是最新的 iText 附加组件。它支持 HTML5 和 CSS 3。已经有一些示例，因此您应该能够快速开始将 html 转换为 pdf 文档。
