mav.setViewName("welcome"); //返回的文件名
mav.addObject("message","hello kitty");
//List
Listlist = new ArrayList();
list.add("java");
list.add("c++");
list.add("oracle");
mav.addObject("bookList", list);
//Map
Map map = new HashMap();
map.put("zhangsan", "北京");
map.put("lisi", "上海");
map.put("wangwu", "深圳");
mav.addObject("map",map);
return mav;
}
}Front-end jsp code
