<label th:each="id,status : ${idList}" th:for="|id${status.index}|" th:text="${id.id}"></label>
th:eachwill iterate over theidList, assign each item toidand create alabelfor each item. The status of the item can be assigned by adding an extra name, separated by a comma (statusin this example).th:forwill set theforattribute of the label. The pipes (|) are used for easy string concatenation.th:textwill set the inner text of the label to the ID.
th:each将迭代idList，将每个项目分配给id并label为每个项目创建一个。可以通过添加一个额外的名称来分配项目的状态，用逗号分隔（status在本例中）。th:for将设置for标签的属性。管道 (|) 用于简单的字符串连接。th:text将标签的内部文本设置为 ID。

You can also use it like this:
你也可以这样使用它：
<label th:each="id : ${idList}" th:for="${'id' + idStat.index}" th:text="{id.id}">
This starts the index from 0
这从 0 开始索引
If you want to start the index from 1 use this
如果你想从 1 开始索引使用这个
<label th:each="id : ${idList}" th:for="${'id' + idStat.count}" th:text="{id.id}">
