原因

The content of elements must consist of well-formed character data or markup.通常是因为代码不符合XML语法规范，像是元素名称使用数字开头、包含空格等，如：

1
2
<0></0>
< a></a>

查看代码后， 发现在JavaScript代码中有下面的用法

1
if (width < 960) {

Thymeleaf在执行到 < 时会尝试去解析从而出错。

解决办法

使用CDATA避免其中的文本被解析

<script type="text/javascript">
    /*<![CDATA[*/
        ...
    /*]]>*/
</script>
