spring 知识点

  

   1.spring 3.1  RedirectAttributes可以解决重复表单的提交

   

@RequestMapping(value="/success.html",method=RequestMethod.GET) 
public String successView(HttpServletRequest request){ 
      Map map = RequestContextUtils.getInputFlashMap(request); 
      if (map!=null) return "success"; 
      else return "redirect:someOtherView"; 
}
