Cannot submit a form on SpringMVC - spring

Question

I am fairly new to SpringMVC and have a form that can not submit to the back-end. I created the form as following and when I submit it error 404 will be returned. I changed action to /MyProject/contact but did not work.
<form class="form-horizontal" role="form" method="post"
action="/contact">
<div class="form-group">
<div class="col-md-12">
<label class="sr-only" for="exampleInputName2">Name
</label> <input type="text" class="form-control" id="name"
name="name" placeholder="Your name" value="">
</div>
</div>
<div class="form-group">
<div class="col-md-12">
<label class="sr-only" for="exampleInputName2">Email
Address</label> <input type="email" class="form-control" id="email"
name="email" placeholder="Your email" value="">
</div>
</div>
<div class="form-group">
<div class="col-md-12">
<label class="sr-only" for="exampleInputName2">Phone
Number</label> <input type="number" class="form-control" id="phone"
name="phone" placeholder="Phone number" value="">
</div>
</div>
<div class="form-group">
<div class="col-md-12">
<label class="sr-only" for="exampleInputName2">Enquiry</label>
<textarea class="form-control" rows="4" name="message"
placeholder="Please enter your enquiry"></textarea>
</div>
</div>
<div class="form-group">
<div class="col-md-2 " style="float: right;">
<input id="submit" name="submit" type="submit" value="Send"
class="btn btn-primary">
</div>
</div>
<div class="form-group">
<div class="col-sm-10 col-sm-offset-2">
<! Will be used to display an alert to the user>
</div>
</div>
</form>
Controller
#Controller
public class ContactController {
#RequestMapping(value="/contact", method=RequestMethod.POST)
public String processForm(Contact contact, Model model){
System.err.println("Contact Name is:" + contact.getName());
return null;
}
}
Error
HTTP Status 404 - /contact
type Status report
message /contact
description The requested resource is not available.

Answer 1

Its beacuse spring does not know how to pass the param Contact contact to your controller method. You need to do couple of things to make it work. Change your form to like below.
<form class="form-horizontal" role="form" method="post" modelAttribute="contact" action="/contact">
Your controller to take contact as model attribute.
#Controller
public class ContactController {
#RequestMapping(value="/contact", method=RequestMethod.POST)
public String processForm(#ModelAttribute Contact contact, Model model){
System.err.println("Contact Name is:" + contact.getName());
return null;
}
}
For a better understanding of what a model attribute does, there are plenty of samples and explanation online. Hope this helps.

I could solve the problem by help of minion's answer, following this tutorial and adding following link
#RequestMapping(value = "/contact", method = RequestMethod.GET)
public ModelAndView contactForm() {
System.err.println("here in GET");
return new ModelAndView("contact", "command", new Contact());
}
