将HTML转换为PDF时出错

错误：“元素类型“链接”必须由匹配的结束标记“”终止。” org.xhtmlrenderer.util.XRRuntimeException：无法加载XML资源（使用TrAX转换器）。 org.xml.sax.SAXParseException; lineNumber：9; columnNumber：3；元素类型“链接”必须以匹配的结束标记“”终止。

该项目基于Springboot和Thymeleaf。

Springboot通过一系列复选框为用户提供表单。表单如下：

将表单数据提交到后端时，会将其放回HTML表单的副本中，以呈现为PDF。我正在使用here概述的技术。

POST控制器：

    @PostMapping("/assessment")
public String greetingSubmit(@ModelAttribute("assessemnt") Assessment assessment, BindingResult result, Model model,
                             HttpServletRequest request, SessionStatus status) throws IOException {

    // GET A LIST OF ATTRIBUTES IN CLASS AND PUT IN MAP
    Map<String, Object> map = oMapper.convertValue(assessment, Map.class);
    Iterator it = map.entrySet().iterator();

    Map<String,String> data = new HashMap<String,String>();
    it = map.entrySet().iterator();
    while (it.hasNext()) {
        Map.Entry pair = (Map.Entry)it.next();
        if (pair.getValue() instanceof Boolean) {
            if (pair.getValue().equals(true)) {
                data.put(pair.getKey().toString(), "checked");
            }
        }
    }

    try {
        pdfGenaratorUtil.createPdf("assessmenttemplate.html",data);
    } catch (Exception e) {
        e.printStackTrace();
    }

和评估模板.html

当行

pdfGenaratorUtil.createPdf("assessmenttemplate.html",data);

正在运行堆栈跟踪是

错误：“元素类型“链接”必须通过匹配终止结束标记“”。 org.xhtmlrenderer.util.XRRuntimeException：无法加载XML资源（使用TrAX转换器）。 org.xml.sax.SAXParseException; lineNumber：9; columnNumber：3；的元素类型“链接”必须由匹配的结束标记终止 “”。

错误很明显-但是，如果我将Assessmenttemple.html上传到w3验证程序，则它会正确地抱怨th标签，但是链接标签未关闭没有问题。

Answer 1

我通过用/>关闭所有标签来修复它。我还必须关闭Meta标签和所有输入标签。
