Thymeleaf SAXParseException：不显示HTML页面

问题描述 投票：0回答：2

我想显示位于我的resources / templates文件夹中的index.html文件，但是我得到一个奇怪的错误，似乎没有意义。 Iam使用Thymeleaf依赖项和ModelAndView显示index.html文件。

这是我的控制器：

@GetMapping("/")
@ResponseBody
public ModelAndView getEvaluatePage() {
    ModelAndView mv=new ModelAndView();
    mv.setViewName("index");
    return mv;
}

这是我的index.html：

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/html">
    <head>
        <link rel="stylesheet"
              href="/webjars/bootstrap/3.3.7-1/css/bootstrap.min.css"/>

                var fd = new FormData(document.getElementById("fileinfo"));
                $("#file-upload-info").fadeIn( "slow" );
                $('span #watson-expression').text('📃🤖');
                $.ajax({
                    url: "/evaluate",
                    type: "POST",
                    data: fd,

                    contentType: false
                }).done(function(data) {
                    console.log(data.measurments);

                    var items = "";
                    $.each(data.measurments, function(i, item) {
                        items = items + item.name + '</br>'
                        items = items + 'f1: ' + item.f1 + '</br>'

                    $('#watson-expression').text('🤖');

我试图查看脚本标记，即使我完全删除它，也会抱怨另一个未正确关闭的标记，即使它们是。我不认为问题在于标签必须是别的东西。

java html spring thymeleaf

Thymeleaf引擎无法解析index.html文档，因为<script>标记未关闭，默认情况下Thymeleaf要求开发人员关闭视图文档中的所有html标记。因此，解决方案就是执行异常消息所说的内容。

更多细节this might be helpful，以及SO answer。

使用链接

Thymeleaf - Strict HTML parsing issue

我按照答案并将LEGACYHTML5用于Thymeleaf作为解决方案，将以下行添加到application.properties文件中

spring.thymeleaf.mode=LEGACYHTML5
spring.thymeleaf.cache=false

和所需的依赖：

    <dependency>
        <groupId>net.sourceforge.nekohtml</groupId>
        <artifactId>nekohtml</artifactId>
        <version>1.9.21</version>
    </dependency>
