[java][spring] springMVC で、redirectする方法

controller.java

  @RequestMapping("test/loggin")
	public ModelAndView getLogginUrl(@PathVariable("language") String language, HttpServletRequest request, HttpServletResponse response) {
		
		setLocale(language, request, response);
		ModelAndView mav = new ModelAndView();

		String logginPageUrl = getLogginPageURL();
		
    // ポイントはここ。　redirect:　を prefix に設定すればよい
  　mav.setViewName("redirect:" + logginPageUrl);
		return mav;
	}
