Thymeleaf th：每个注释都包含 din 模板

Question

我有一个 Thymeleaf 片段，其中包含一些状态文本和一个 th:each ，它没有出现在输出中。 我已经能够将模型值包含在输出列表中，并显示为 [[ 8,9...][..]...]] 所有值都是正确的。 我已经使用logging.level.org.thymeleaf=trace运行来获取日志，但似乎对我来说没有任何问题。

片段是：

   <span th:fragment="view">
    <div class="centered">
        <h1 th:text="${sudoku_description}"></h1>
        <h1 th:text="${sudoku}"></h1>
        <div class="centered" >
            <th:block th:each="puzzledata, rowStat : ${row}">
                <div class="sudoku-row" >
                    <th:block th:each="row, colStat : ${cell}">
                        <div class="sudoku-cell" row="rowStat.index" col="colStat.index" th:text="${cell}"></div>
                    </th:block>
                </div>
            </th:block>
        </div>
       </div>
    </span>

2 个标签存在且正确，但检查时以下

<div class="centered" >

为空。 我尝试将 th:block 更改为 div 没有任何区别。 从 Intelij 运行，控制台中没有异常或错误。

Answer 1

每天的开发日都证明了一个人是多么愚蠢。

问题是其中的值。每个方向都是错误的！

这有效：

<th:block th:each="row, rowStat : ${puzzledata}">

这不：

 <th:block th:each="puzzledata, rowStat : ${row}">
