SpringMVC 接收表单数据的方式

1.@RequestParam

 

1     @RequestMapping(value = "/xxxx.do")  
2     public void create(@RequestParam(value="userName") String userName) throws Exception {  
3           
4     }  

 

2.@PathVariable

1     @RequestMapping(value="/{groupId}.do")  
2     public void detail(@PathVariable long groupId){  
3         groupRepository.selectOne(groupId);  
4     }  

 

@ModelAttribute

 

1     @RequestMapping(value = "/xxxx.do")  
2     public String create(@ModelAttribute User user) throws Exception {  
3         userService.insert(user);  
4         return "redirect:/user/create.do";  
5     }  

 

 

 

4.Request对象

 

1     public ModelAndView method1(HttpServletRequest request,  
2                HttpServletResponse respnose) throws ServletException, IOException {  
3            Map model = new HashMap();  
4            model.put("message", "你调用的是方法１");  
5             return new ModelAndView("/index.jsp", "model", model);  
6      }
