如何在Thymeleaf页面中显示ArrayList对象

Question

I try to display Arraylist object in Thmeleaf page but I got null for the value.
I can display the arraylist in controller on console. Is it correct the way I pass arraylist in function.

In controller

@RequestMapping("/searchSummon")
public String Search(Model model) {

    model.addAttribute("summonsDetailType", new SummonsDetailType());
    model.addAttribute("rowType", new RowType());

    return "searchSummon";
}

@RequestMapping(value = "/searchProcess", method = RequestMethod.POST)
public String searchProcess(SummonsDetailType summonsDetailType, RowType rowType) {

    ArrayList<RowType> rowTypes2 = new ArrayList<RowType>();
    SummonsDetailType summonsDetailType2 = pdxiRes.getRequest().getSummonsDetail();

    for (RowType rowType3 : summonsDetailType2.getRow()) {
        rowTypes2.add(rowType3);
    }

    System.out.println(rowTypes2.get(0).getDistrictCode());
    return "/searchResult";
}

html page

<tr th:each="rowType : ${rowType}">
  <td th:text="'NRIC NO: ' + ${rowType.DistrictCode}"></td>
</tr>

我通过在模型中添加arraylist解决了这个问题

model.addAttribute("rowTypes2", rowTypes2);
