@ModelAttribute 相当于struts2的ModelDriver<>

用来拿到form 传过来的对象。。

代码::

@RequestMapping(value="user/addUser.do",method=RequestMethod.POST)    publicStringaddUser(Modelmodel,@ModelAttribute("user")Useruser){        System.out.println("11111111111111");        System.out.println(user.getUsername());        System.out.println(user.getPassword());        return"redirect:/success.jsp";    }
