嘗試以下方法
<th:block th:each="comment : ${comments}">
<p th:text="${comment.content}">comment</p>
<div th:fragment="f_call(comment)"
th:unless="${#lists.isEmpty(comment.children)}" >
<div th:each="child : ${comment.children}" th:inline="text">
[[${child.content}]]
<div th:replace="this::f_call(${child})"></div>
</div>
</div>
</th:block>
