Question

In Spring MVC, is there anyway to select a controller method using a form element value? For example, let’s say we have two buttons both with name “action” in a form. Is there anyway to execute different controller methods based on the button which was clicked by the user without using any javascript?

Yes, using @RequestMapping(params="..."). See docs.

You can narrow path mappings through parameter conditions: a sequence of “myParam=myValue” style expressions, with a request only mapped if each such parameter is found to have the given value. For example:

@Controller
@RequestMapping("/owners/{ownerId}")
public class RelativePathUriTemplateController {

  @RequestMapping(value = "/pets/{petId}", params="myParam=myValue")
  public void findPet(@PathVariable String ownerId, @PathVariable String petId, Model model {    
    // implementation omitted
  }
}
