The client locale is {}.", locale);				Date date = new Date();		DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);				String formattedDate = dateFormat.format(date);				model.addAttribute("serverTime", formattedDate );				return "home";	}		@RequestMapping(value = "/Two", method = RequestMethod.GET)	public String Two(			int id,Model model			) {		logger.info("two");				System.out.println("hello2 action:"+id);          model.addAttribute("name", "huangjie");          //这个只有值没有键的情况下,使用Object的类型作为key,String-->string          model.addAttribute("ok");  								return "Two";	}	}
  2. Two.jsp 视图
