SpringMVC 接收表单数据的方式

1.@RequestParam

@RequestMapping(value = "/xxxx.do")public void create(@RequestParam(value="userName") String userName) throws Exception {}

2.@PathVariable

@RequestMapping(value="/{groupId}.do")public void detail(@PathVariable long groupId){groupRepository.selectOne(groupId);}

3.@ModelAttribute

@RequestMapping(value = "/xxxx.do")public String create(@ModelAttribute User user) throws Exception {userService.insert(user);return "redirect:/user/create.do";}

4.Request对象

public ModelAndView method1(HttpServletRequest request,           HttpServletResponse respnose) throws ServletException, IOException {       Map model = new HashMap();       model.put("message", "你调用的是方法１");        return new ModelAndView("/index.jsp", "model", model); }
