Spring ModelAttribute not biding values Tomcat 9, Spring 5 MVC - spring-mvc

Question

I migrated from Spring 3 to 5, upgraded to Tomcat 9. After upgrading not able to get the values from JSP to Controller. #ModelAttribute is not binding the values entered in JSP, while submitting the form.
JSP Code:
<form:form action="/login" modelAttribute="identity" id="loginForm" cssClass="clearfix nodisplay">
<div class="grouping text">
<label for="email">E-mail Address</label>
<form:input path="email" id="email" cssClass="regInput" cssErrorClass="error" />
<form:errors path="email" cssClass="errors" />
</div>
<div class="grouping text">
<label for="pwd">Password</label>
<form:password path="pwd" id="pwd" cssClass="regInput" cssErrorClass="error" autocomplete="off" />
<form:errors path="pwd" cssClass="errors" />
</div>
<div class="grouping remember">
<input type="checkbox" name="remember" id="remember" />
<label for="remember">Remember Me</label>
</div>
<div class="btns clearfix">
<span class="login-btn">
<input type="hidden" name="cookieExist" id="cookieExist" value="false" />
<button type="button" name="login" class="btn js-login-btn"><span class="pictos">K</span> Login</button>
</span>
<span class="password-forget">
I forgot my password
</span>
</div>
</form:form>
Controller Code
#Controller
public class LoginController {
#RequestMapping(method=RequestMethod.GET, value="/login")
public String loginGet(HttpServletRequest request, HttpServletResponse response, ModelMap modelMap,
#ModelAttribute Identity identity){
// commented business logic code
return "login";
}
#RequestMapping(method=RequestMethod.POST, value="/login")
public String loginPost(HttpServletRequest request, HttpServletResponse response,
ModelMap modelMap, #ModelAttribute("identity") Identity identity, BindingResult bindingResult) {
//commented out business logic
return "dashboard";
}
#ModelAttribute("identity")
public Identity formBackingObject() {
return new Identity();
}
}
I have migrated with no webxml way, not sure what else i'm missing here?

No need of action here in the form tag. Mention method in the form tag. So chnage to:
<form:form modelAttribute="identity" method="post" id="loginForm" cssClass="clearfix nodisplay">
And also change your primary action button to:
<input type="submit" ... />
