2、TestController.java

@Controller

@Scope(value = "prototype")

@RequestMapping("/")

public class TestController {

@RequestMapping(value="/testdemo") //从上一个页面跳转过来,如果只是看看效果直接输入http://localhost:8080/项目名/testdemo

public String Test(Model model)

{

List>list1=new ArrayList();

List l1 = Arrays.asList("二级菜单1","二级菜单2","二级菜单3");//模拟获得数据

List l2 = Arrays.asList("/url1","/url2","/url3");

List>list2=new ArrayList();

List l3 = Arrays.asList("三级菜单1","三级菜单2","三级菜单3","三级菜单4");//模拟获得数据

List l4 = Arrays.asList("/url1","/url2","/url3","/url4");

list1.add(l1);

list1.add(l2);

list2.add(l3);

list2.add(l4);

model.addAttribute("itemname1",list1);

model.addAttribute("itemname2",list2);
