spring mvc jsp怎么获得ModelAndView设置的值 急急急！

@RequestMapping("user") public ModelAndView excute(@RequestParam("username") String username,String password){ ModelAndView mav = new ModelAndView(); while(userDao.findUser(username, password)){ mav.addObject("username", username); mav.setViewName("success"); return mav; } mav.setViewName("error"); return mav; } 怎么在jsp页面获得username的值呢？

Answer 1

Map model =new HashMap
mode.put('list',userlist)//userlist是个Arraylist之类的

return new ModelAndView("page",model);

在jsp页面中使用jstl标签取出值以下自动循环取出每个值
<c:forEach items="${list}" var="user">
${user.username}
${user.password}
${user.address.value}//可以去对象中的对象的值属性
