 @Controller

 public class MAVTest {

     public MAVTest() {

         // TODO Auto-generated constructor stub

     }

     @RequestMapping(value = "login")

     public ModelAndView login() {

         System.out.println("MAVTest.java login()....");

         ModelAndView mav = new ModelAndView();

         mav.setViewName("welcome");

         mav.addObject("msg", "hello kitty");

         // List

         List<String> list = new ArrayList<String>();

         list.add("java");

         list.add("c++");

         list.add("oracle");

         mav.addObject("bookList", list);

         // Map

         Map<String, String> map = new HashMap<String, String>();

         map.put("zhangsan", "北京");

         map.put("lisi", "上海");

         map.put("wangwu", "深圳");

         mav.addObject("map", map);

         return mav;

     }

 }
