springmvc模版赋值4种方法

    @RequestMapping("/model1")
    public String model1(ModelMap modelMap, Model model, Map<String,User> u3,@ModelAttribute("u4") User u4){

        modelMap.addAttribute("u1",new User("01","King","t;stmdtkg"));

        model.addAttribute("u2",new User("02","King","t;stmdtkg"));

        u3.put("u3",new User("03","King","t;stmdtkg"));

        u4.setName("04");
        return "index/model";
    }
