#ModelAttribute is not working in spring MVC with post - spring

Question

Hi I am developing my first spring mvc application. I am trying to add a form to db. For this I am using #ModelAttribute and it is not working.
My Controller:
#Controller
public class AddKPI {
#RequestMapping("/getAddKPIForm")
public ModelAndView addKPI(){
ModelAndView modelAndView = new ModelAndView("getAddKPIForm","kpi", new KPI());
String auditInfo = "User : "+getCurrentDateInStringFormat_YYYYMMDD_HHSSMM();
modelAndView.addObject("auditInfo",auditInfo);
return modelAndView;
}
#RequestMapping(value="/addKPITODB")
public ModelAndView add2DB(#ModelAttribute("kpi") KPI kpi){
System.out.println("In controller Method");
System.out.println("kpi.getKpi_name() = "+kpi.getKpi_name());
return new ModelAndView("adding_Success");
}
public static String getCurrentDateInStringFormat_YYYYMMDD_HHSSMM() {
String date_Str = null;
try {
Date date = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
date_Str = sdf.format(date);
} catch (Exception pe) {
// TODO: Add catch code
pe.printStackTrace();
}
return date_Str;
}
}
My Form Code:
<div align="center">
<div style="width: 650px;">
<form:form class="form-horizontal" method="POST" modelAttribute="kpi" commandName="kpi" action="addKPITODB" >
<form:input type="hidden" name="id" value="122" path="id"></form:input>

When I am hitting submit button it is not going to controller method "/addKPITODB" I am getting 404 error(URL is http://localhost:6006/EasyRUN/addKPITODB). If I remove #ModelAttribute it is going to controller method. What is the mistake I am doing. Please correct me.
Your help will be highly appreciate. Thank you.

I created a sample project with your code which works just fine:
git clone https://github.com/denis-zhdanov/spring-playground.git
cd spring-playground/
git checkout so-33429407
export GRADLE_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,address=9999,server=y,suspend=n"
./gradlew jettyRun
Wait until the following line is printed - ':jettyRun > Running at http://localhost:8080/spring-playground'
Connect by remote debugger to the localhost:9999
Set a breakpoint at the org.denis.test.spring.mvc.MyController.add2DB()
Open 'http://localhost:8080/spring-playground/form.html' at the browser
Type any text there and press
The breakpoint is hit
