@RequestMapping(value="/list",method=RequestMethod.GET)?? ?public String list(Model model) {????????? //前臺輸出必須使用形如${ul.value.id }的形式?? ??? ?model.addAttribute("userList",userList);?? ??? ?return "user/userList";?? ?}?? ??? ?@RequestMapping(value="/userlist",method=RequestMethod.GET)?? ?public String list(HttpServletRequest request) {????? //前臺輸出必須使用形如${user.id }的形式?? ??? ?List<User> userList = new ArrayList<User>();?? ??? ?userList.add(new User("1","yonghu1","121","[email protected]"));?? ??? ?userList.add(new User("2","yonghu2","122","[email protected]"));?? ??? ?userList.add(new User("3","yonghu3","123","[email protected]"));?? ??? ?request.setAttribute("userList", userList);?? ??? ?return "user/userList";?? ?}為什么前臺取值時得使用不同的方法呢？HttpServletRequest和model不都是以map鍵值對的形式存數據的嗎？
