Spring MVC – Multiple submit button to a Form

if the form has these buttons specified:

input type="submit" class="button" name="save" value="Save"
input type="submit" class="button" name="delete" value="Delete"
input type="submit" class="button" name="cancel" value="Cancel"

you may direct to different url request according to button pressed with one controller.

for cancel button,

@RequestMapping(params = "cancel", method = RequestMethod.POST)
public String cancelUpdateUser(HttpServletRequest request) {
    return "redirect:/users.html";
}

what request mapping does is to scan post request if it contains params name = cancel.

for save button,

@RequestMapping(params = "save", method = RequestMethod.POST)
public String saveUser(HttpServletRequest request, @ModelAttribute User user, BindingResult result, SessionStatus status) {
    // validate your result
    // if no errors, save it and redirect to successView.
}
