Code UPDATE V1
Here i made some changes it is hitting the Controller page,but there object is EMPTY [] ..Here is Proof of Image
@RestController
@PostMapping(value="/updatesetcharges")
public ModelAndView doUpdateSetCharges(@ModelAttribute WrpSetCharges tempEntSetChargesList)
ModelAndView respondResult = new ModelAndView();
try {
List<EntSetCharges> entSetChargesList = new ArrayList<>();
for(EntSetCharges ent : tempEntSetChargesList.getTempEntSetChargesList())
{ //logics goes here
in HTML
<form id="setchargesformid" method="post" th:object="${tempEntSetChargesList}" th:action="@{/updatesetcharges}">
Wrapper class
public class WrpSetCharges {
private List<EntSetCharges> tempEntSetChargesList = new ArrayList<>();
public List<EntSetCharges> getTempEntSetChargesList() {
return tempEntSetChargesList;
public void setTempEntSetChargesList(List<EntSetCharges> tempEntSetChargesList) {
this.tempEntSetChargesList = tempEntSetChargesList;
In my case, I use @RequestBody to mapping the input to my model. So it would be
@PostMapping(value="/updatesetcharges")
public ModelAndView doUpdateSetCharges(@RequestBody List<EntSetCharges> tempEntSetChargesList){
// Do your stuff and dont forget return
return new ModelAndView();
And also dont forget to add empty constructor in your entity.
Put your list in a wrapper class and use that class as your ModelAttributes
class ListWrapper{
List<EntSetCharges> tempEntSetChargesList;
public List<EntSetCharges> getTempEntSetChargesList() {
return tempEntSetChargesList;
public void setTempEntSetChargesList(List<EntSetCharges> tempEntSetChargesList) {
this.tempEntSetChargesList = tempEntSetChargesList;
and search here on how to bind list of objects in thymeleaf.
ex. how-to-bind-an-object-list-with-thymeleaf
below example of binding items in your list.
<tbody>
<tr th:each="currentClient, stat : *{clientList}">
<input type="checkbox" th:field="*{clientList[__${stat.index}__].selected}" />
<input type="hidden" th:field="*{clientList[__${stat.index}__].clientID}" />
<input type="hidden" th:field="*{clientList[__${stat.index}__].ipAddress}" />
<input type="hidden" th:field="*{clientList[__${stat.index}__].description}" />
<td th:text="${currentClient.getClientID()}"></td>
<td th:text="${currentClient.getIpAddress()}"></td>
<td th:text="${currentClient.getDescription()}"></td>
</tbody>
