Question

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

@RequestMapping({"/someurl"})
public ModelAndView execute(Model model) {
    if (someCondition) {
        //forward to controller A
    } else {
        //forward to controller B
    }
}

All of the controller have dependencies injected by Spring, so I can’t just create them and call them myself, but I want the request attributes to be passed on to the other controllers.

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";
    }
}
