Spring MVC控制器HTTP GET查询参数

您应该有一个映射到edititem.htm的控制器。(也许a SimpleFormController )

覆盖两个showForm方法中的一个,用项目填充您的模型:

protected ModelAndView showForm(HttpServletRequest request, HttpServletResponse response, BindException errors){
//get the id
int id = Integer.parseInt(request.getParameter("id"));

// get the object
Item item = dao.getItemById(id);
return  new ModelAndView(getFormView(), "item", item);
}
