Spring 3.0 forwarding request to different controller

Question

What is the proper way to forward a request in spring to a different controller?

@RequestMapping({\"/someurl\"})
public ModelAndView execute(Model model) {
    i         


        

Answer 1

You can use Spring RedirectView to dispatch request from one controller to other controller. It will be by default Request type "GET"

RedirectView redirectView = new RedirectView("/controllerRequestMapping/methodmapping.do", true);

Answer 2

You can use view name like "redirect:controllerName" or "forward:controllerName". The latter will reroute request to another controller and former will tell browser to redirect request to another url.

Answer 3

Try returning a String instead, and the String being the forward url.

@RequestMapping({"/someurl"})
public String execute(Model model) {
    if (someCondition) {
        return "forward:/someUrlA";
    } else {
        return "forward:/someUrlB";
    }
}
