通用和通用html thyemleaf数据表页面spring-boot java

Question

I have more than 300 controllers. I would like to have one and only one HTML page for all controllers.

I know to make loop over a list like this in thyeleaf.

<tbody>
    <tr th:each="client : ${customerList}">
        <td th:text="${client.getClientID()}"></td>
        <td th:text="${client.getIpAddress()}"></td>
        <td th:text="${client.getDescription()}"></td>
    </tr>
</tbody>

But how to iterate over any list without specifying properties like clientID or ipAddress or description? And be able to do something like this with generic operation:

<td><a th:href="'/delete/' + ${client.getClientID}">Delete</a></td>
<td><a th:href="'/edit/' + ${client.getClientID}">Edit</a></td>

hope to be clear

Please see picture .

Answer 1

You dont have to specify getClientID() , getIpAddress() at all for just looping through the list.

<tr th:each="client : ${customerList}">
    <td>Repeat me</td>
</tr>

If you use the above loop you will get <td>Repeat me</td> as many times as the size of the list customerList .

Answer 2

You can store the data in your model as List<Map<String, String>> where every object of the list is represented as a map , map 's key is object attribute name, and value is object's attribute value.

Then on your view, this will do:

<table th:if="${not #lists.isEmpty(listOfMaps)}">
   <thead>
      <!--Columns detection/display -->
      <th th:each="firstObjEntry: ${listOfMaps[0]}" th:text="${firstObjEntry['key']}">
      </th>
   </thead>
   <tbody>
      <tr th:each="objMap: ${listOfMaps}">
         <td th:each="objMapEntry : ${objMap}" th:text="${objMapEntry['value']}"></td>
      </tr>
   </tbody>
