Neither BindingResult nor plain target object for bean name available as request attribute

I am creating Spring Boot application using Thymeleaf template.

Find the code snippet.

//Controller code

@GetMapping("create")

public ModelAndView createEmp() {

ModelAndView m = new ModelAndView();

m.setViewName("employee");

m.addObject("empobj", new Employee());

return m;

}

//Employee.java

public class Employee { 

 private Integer empId; 

 private String empName; 

}

//Template code

<table>

<form action="#" th:action="@{/app/save}" method="POST">

  <tr><td th:text="#{emp.name}"></td>

     <td> <input type="text" th:field="*{empName}" />  </td>

</tr>

</form>

</table>

You are missing configuring empobj in <form>.

<form action="#" th:action="@{/app/save}" th:object="${empobj}" method="POST">
      <tr><td th:text="#{emp.name}"></td>
          <td> <input type="text" th:field="*{empName}" />  </td>
    </tr>
</form>
