Question

I have many input fields in a form to post data to server side.
And in controller, I want to get all attributes in ModelMap like this:

public String save(ModelMap model) {
    ....
}

I don’t want to use @RequestParam since there are so many fields to be sent. I think the data in a form will be posted and saved in ModelMap automatically, but its not working

Could anyone help me?
Thanks.

You should use a @ModelAttribute in the form handler

@RequestMapping(value="/submitform", method = RequestMethod.POST)
public String save(@ModelAttribute("mydata") MyData myData) {

 //do something with
 //myData.getField1();
 //myData.getFiled2();
}

and this is how you will send the page to the form

@RequestMapping("/fillform")
public String loadForm(ModelMap model) {

  //you could also fill MyData, to do autofill on the html form
  model.put("mydata", new MyData());

  return "fillform"; //[jsp]view resolver will pick up fillform.jsp 
 }
