Thymeleaf multiple submit button in one form

I have a fragment of HTML page with one form and 2 button:

<form action="#" data-th-action="@{/action/edit}" data-th-object="${model}" method="post">
<button type="submit" name="action" value="save">save</button>
<button type="submit" name="action" value="cancel">cancel</button>

And the controller:

@RequestMapping(value="/edit", method=RequestMethod.POST)
public ModelAndView edit(@ModelAttribute SomeModel model,
@RequestParam(value="action", required=true) String action) {

if (action.equals("save")) {
// do something here

if (action.equals("cancel")) {
// do another thing
return modelAndView;

This work good, but if I have more button, I must add more
statement to check the
string. Is there another way that I can create one action for each button in the form?

You can create separate methods with different @RequestMappings using the params variable.

@RequestMapping(value="/edit", method=RequestMethod.POST, params="action=save")
public ModelAndView save() {}

@RequestMapping(value="/edit", method=RequestMethod.POST, params="action=cancel")
public ModelAndView cancel() {}
