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<list<string>>list1=new arraylist();
list<string> 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<string> l2 = arrays.aslist("/url1","/url2","/url3");
list<list<string>>list2=new arraylist();
list<string> 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<string> 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);
return"testdemo";
