Unable to get thymeleaf form data in spring mvc

I am new to Thymeleaf, I try to execute a simple form submittion example using Thymeleaf and Spring MVC. I wrote the code according to Thymeleaf documentation. But I am getting null values in the controller.

<form action="thymeleafexample/thymeleaf.html" th:action="@{/thymeleaf}" th:object="${loginModel}" method="post"> <table> <tr> <td th:text="#{emp.empId.label}">Emp ID</td> <td><input type="text" th:field="*{empId}"/></td> </tr> <tr> <td th:text="#{emp.empName.label}">Emp Name</td> <td><input type="text" th:field="*{empName}"/></td> </tr> <tr> <td> <button type="submit" name="save" th:text="#{${'.emp.button.label'}}">submit</button> </td> </tr> </table> </form> 

and my Controller is

@RequestMapping(value = "/thymeleaf", params = {"save"}) public String save(@Validated LoginModel loginModel, final BindingResult bindingResult, ModelMap model) { if (bindingResult.hasErrors()) { return "thymeleaf"; } System.out.println(loginModel); System.out.println(loginModel.getEmpName()); return "/thymeleaf"; } 

and my Model class is

public class LoginModel { private String empName; private int empId; public void setEmpId(int empId) { this.empId = empId; } public int getEmpId() { return empId; } public String getEmpName() { return empName; } public void setEmpName(String empName) { this.empName = empName; } }
