问题似乎是变量表达式方法#seo.getCategoryTitlePattern（）不再存在。如果查看seovariableexpression，正确的方法是使用#seo.getMetaProperties(category).get('title')。更好的选择是在一般的seometaproperties.html模板中执行类似的操作，以呈现页面的任何元属性：

<th:block th:each="metaProperty : ${metaProperties}" th:with="key=${metaProperty.key}, value=${metaProperty.value}">
    <th:block th:if="${value != null}">
        <title th:if="${key == 'title'} and ${#strings.contains(value,'#seoElement')}" th:utext="${__${value}__}"></title>
        <title th:if="${key == 'title'} and not ${#strings.contains(value,'#seoElement')}" th:utext="${value}"></title>

        <link th:if="${key == 'canonicalUrl'}" rel="canonical" th:attr="href=${value}"/>

        <meta th:if="${key == 'metaDescription'} and ${#strings.contains(value,'#seoElement')}" name="description" th:attr="content=${__${value}__}"/>
        <meta th:if="${key == 'metaDescription'} and not ${#strings.contains(value,'#seoElement')}" name="description" th:attr="content=${value}"/>

        <th:block th:if="${#strings.startsWith(key, 'og:')}">
            <meta th:if="${#strings.contains(value,'#seoElement')}" th:attr="property=${key}, content=${__${value}__}"/>
            <meta th:unless="${#strings.contains(value,'#seoElement')}" th:attr="property=${key}, content=${value}"/>
        </th:block>

        <th:block th:if="${#strings.startsWith(key, 'twitter:')}">
            <meta th:if="${#strings.contains(value,'#seoElement')}" th:attr="name=${key}, content=${__${value}__}"/>
            <meta th:unless="${#strings.contains(value,'#seoElement')}" th:attr="name=${key}, content=${value}"/>
        </th:block>
    </th:block>
</th:block>

这可以包含在category.html文件中，如下所示：

<th:block th:include="seo/partials/seoMetaProperties" th:with="metaProperties=${#seo.getMetaProperties(category)}" />
