一个小小的demo，演示从Controller层传参到视图，有使用到SpringMvc、jstl标签
效果图：
1、testdemo.jsp
<%@ page language="java" import="java.util.*"

<body>
<ul class="layui-nav layui-nav-tree" lay-filter="test">
<!-- 侧边导航: <ul class="layui-nav layui-nav-tree layui-nav-side"> -->
<li class="layui-nav-item layui-nav-itemed"><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" >默认展开</a>
<dl class="layui-nav-child">

</dd>
</c:forEach>
</dd>
</dl></li>
<li class="layui-nav-item"><a href="">产品</a></li>
<li class="layui-nav-item"><a href="">大数据</a></li>
</ul>
<!-- 注意：如果你直接复制所有代码到本地，上述js路径需要改成你本地的 -->
<script src="layui/layui.js"></script>
<script>
layui.use('element', function() {
var element = layui.element; //导航的hover效果、二级菜单等功能，需要依赖element模块
//监听导航点击
element.on('nav(demo)', function(elem) {
layer.msg(elem.text());
});
});
</script>
</body>
</html>
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";
}
}
以上这篇Layui 后台加载菜单栏名称以及url的例子就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持亿速云。
