将表单发布回控制器时,我遇到了很多困难,控制器应该只包含用户可以编辑的对象的arraylist.

表单正确加载,但是当它发布时,它似乎永远不会发布任何内容.

这是我的表格:

<form action="#" th:action="@{/query/submitQuery}" th:object="${clientList}" method="post">

<table class="table table-bordered table-hover table-striped">
<thead>
    <tr>
        <th>Select</th>
        <th>Client ID</th>
        <th>IP Addresss</th>
        <th>Description</th>            
   </tr>
 </thead>
 <tbody>     
     <tr th:each="currentClient, stat : ${clientList}">         
         <td><input type="checkbox" th:checked="${currentClient.selected}" /></td>
         <td th:text="${currentClient.getClientID()}" ></td>
         <td th:text="${currentClient.getIpAddress()}"></td>
         <td th:text="${currentClient.getDescription()}" ></td>
      </tr>
  </tbody>
  </table>
  <button type="submit" value="submit" class="btn btn-success">Submit</button>
  </form>

以上工作正常,它正确加载列表.但是,当我POST时,它返回一个空对象(大小为0).我相信这是由于缺乏th:field,但无论如何这里是控制器POST方法:

...
private List<ClientWithSelection> allClientsWithSelection = new ArrayList<ClientWithSelection>();
//GET method
...
model.addAttribute("clientList", allClientsWithSelection)
....
//POST method
@RequestMapping(value="/submitQuery", method = RequestMethod.POST)
public String processQuery(@ModelAttribute(value="clientList") ArrayList clientList, Model model){
    //clientList== …
