SSM框架下如何实现数据从后台传输到前台

@RequestMapping(value=\"/TestDemo\",method=RequestMethod.POST)
    public String TestDemo(Model model, member mbr,HttpServletRequest request) 
    {
        String text = \"\";
        request.setAttribute(\"textname\", text); 
        return \"\";
    }

@RequestMapping(value=\"/TestDemo\")
    public ModelAndView TestDemo() 
    {
        String text = \"hello!\";
        //ModelAndView中三个参数，跳转页面，接收返回数据的属性，返回的数据
        ModelAndView modelAndView = new ModelAndView(\"Demo\",\"textname\",text); 
        return modelAndView;
    }

@RequestMapping(value=\"/TestDemo\")
    public String TestDemo(Model model) 
    {
        String text = \"hello!\";
        model.addAttribute(\"textname\", text);
        return \"Demo\";
    }
