我正在使用

ByteArrayOutputStream bytes = pdfRenderingService.render(template: "/templates/offers", model: [poos:poos, tasks:tasks, skus:skus])

但是它会抛出错误：

org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 3; The markup in the document preceding the root element must be well-formed.

我可以做些什么来完成这项工作？我已经做了一些研究，我发现这是关于XML格式的东西，但我无法弄清楚是什么问题。已经去了xHTML验证器...

有人可以帮我弄清楚如何让这个渲染工作？我做错了什么？

（如果这只是Grails Rendering，我可以使用其他html到pdf库吗？）

提前致谢！

Grails渲染插件 - Reference Documentation

您必须在GSP一开始就declare DOCTYPE，如：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
 "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

因此，您的模板将为_offers.gsp，如下所示：
