使用文本语法模板为项目列表解析 thymeleaf 模板时出错，解析列表时抛出错误

Question

这是我的模板，我想列出每个项目的项目 ID。但是不断出错

[# th:each="item : ${items}"]
  - [(${item.id})]
[/]

我正在使用 kotlin 代码

 val items = listOf(Item(id = "CocaCola123", qty = BigDecimal.ONE))
        val templateEngine = TemplateEngine()
        val ctx = Context()
        ctx.setVariable("item", items)
        templateEngine.process(template, ctx)

我收到如下所示的错误

[main] ERROR org.thymeleaf.TemplateEngine - [THYMELEAF][main] Exception processing template "[# th:each="item : ${items}"]   - [(${item.id})] [/]": An error happened during template parsing (template: "[# th:each="item : ${items}"]
  - [(${item.id})]
[/]")
org.thymeleaf.exceptions.TemplateInputException: An error happened during template parsing (template: "[# th:each="item : ${items}"]
  - [(${item.id})]
[/]")

Caused by: org.thymeleaf.exceptions.TemplateProcessingException: Exception evaluating OGNL expression: "item.id" (template: "[# th:each="item : ${items}"]
  - [(${item.id})]
[/]" - line 2, col 7)

帮助我做错了什么？ 我正在关注 thymeleaf 网站处理文本语法的文档。

模板

[# th:each="item : ${items}"]
  - [(${item})]
[/]

让我输出

[# th:each="item : ${items}"]
  - [Item(id=CocaCola123, qty=1)]
[/]"

我无法访问该 ID

// Change line

ctx.setVariable("项目", 项目)

// to bellow line

ctx.setVariable("物品", 物品)

// observe the change in key which you are using
