use RedirectAttributes as bean spring mvc

Is there a way to do this in spring mvc; I want to @Autowired RedirectAttributes:

@Controller
public class RegistrationController {
    @Autowired private RedirectAttributes redirectAttributes;

    @RequestMapping(value = SIGNUP_ROUTE, method = RequestMethod.POST)
    public String signUpPage(ModelMap modelMap, User user) {
        save(user);
        redirectAttributes.addFlashAttribute("success", "Very good");
        return "redirect:/sign-in";
    }
}

Exception I get:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'registrationController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.springframework.web.servlet.mvc.support.RedirectAttributes com.myhome.controller.RegistrationController.redirectAttributes; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.web.servlet.mvc.support.RedirectAttributes] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

One way to inject the dependency in your code could be adding an extra parameter of the class RedirectAttributes

@Controller
public class RegistrationController {

    @RequestMapping(value = SIGNUP_ROUTE, method = RequestMethod.POST)
    public String signUpPage(ModelMap modelMap, RedirectAttributes rda, User user) {
        save(user);
        rda.addFlashAttribute("success", "Very good");
        return "redirect:/sign-in";
    }
}
