thymeleaf the menu tree

1. Object creation:

package com.demo.Model;

import lombok.Getter;
import lombok.Setter;
import lombok.ToString;

import java.io.Serializable;
import java.util.List;

@Getter
@Setter
@ToString
public class PriMenu implements Serializable {

    private static final long serialVersionUID = -7458870847408160287L;

    private Long id;
    private Long pId; // 父节点id
    private String menuName;// 菜单名称
    privateMenuUrl String; // access address 
    Private String priLevel; // menu hierarchy 
    Private String priPath; // permissions menu hierarchy path 
    Private String Status; // status 0 Available 1 disabled 
    Private Long creatorId; // Created the above mentioned id 
    Private String createTime;
     Private List <PriMenu> sonList; 

    public PriMenu () { 
    }

2. Object Initialization

package com.demo.Common.constants;
import com.demo.Model.PriMenu;
import java.util.ArrayList;
import java.util.List;

public class MenuDemo {
    //菜单假数据
    public static List<PriMenu> Initialization(){
        List<PriMenu> list = new ArrayList<PriMenu>();

        PriMenu priMenu1 = new PriMenu();
        priMenu1.setMenuName("系统管理");

        List<PriMenu> list1 = new ArrayList<PriMenu>();
        PriMenuSon1 PriMenu = new new PriMenu (); 
        priMenuSon1.setMenuName ( "Menu Manager" ); 
        PriMenu priMenuSon2 = new new PriMenu (); 
        priMenuSon2.setMenuName ( "Role Management" ); 
        PriMenu priMenuSon3 = new new PriMenu (); 
        priMenuSon3.setMenuName ( "permission management " ); 
        PriMenu priMenuSon4 = new new PriMenu (); 
        priMenuSon4.setMenuName ( " user management " ); 

        list1.add (priMenuSon1); 
        list1.add (priMenuSon2); 
        list1.add (priMenuSon3); 
        list1.add (priMenuSon4); 
        priMenu1.setSonList (List1);
        list.add (priMenu1); 


        PriMenu2 PriMenu = new PriMenu (); 
        priMenu2.setMenuName ( "列表管理" ); 

        A List <PriMenu> List2 = new an ArrayList <PriMenu> (); 
        PriMenuSon5 PriMenu = new PriMenu (); 
        priMenuSon5.setMenuName ( "借款列表" ); 
        PriMenuSon6 PriMenu = new PriMenu (); 
        priMenuSon6.setMenuName ( "日志管理" ); 

        list2.add (priMenuSon5); 
        list2.add(priMenuSon6);
        priMenu2.setSonList (list2); 
        list.add (priMenu2); 

        PriMenu priMenu3 = new new PriMenu (); 
        priMenu3.setMenuName ( "management function" ); 

        List <PriMenu> list3 = new new the ArrayList <PriMenu> (); 
        PriMenu priMenuSon7 = new new PriMenu ( ); 
        priMenuSon7.setMenuName ( "send a message" ); 
        priMenuSon7.setMenuUrl ( "toUEditor.jhtml" ); 
        PriMenu priMenuSon8 = new new PriMenu (); 
        priMenuSon8.setMenuName ( "export table" ); 

        list3.add (priMenuSon7);
        list3.add (priMenuSon8); 
        priMenu3.setSonList (list3); 
        list.add (priMenu3); 
        return statement list; 
    } 
}

3.Controller

package com.demo.Controller;
import com.demo.Common.constants.MenuDemo;
import com.demo.Model.PriMenu;
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;


@Slf4j
@Controller
public class ModelAndViewController {
      
   @RequestMapping("toMain.jhtml")
    public String mainView(HttpServletRequest request, ModelMap model) {
        log.info("跳转到后台首页");
        Map<String, Object> param = new HashMap<String, Object>();
        List<PriMenu> list = new ArrayList<PriMenu>();
        list=MenuDemo.Initialization();
        model.addAttribute("menus", list);
        return "pri/main";
    }
}

4.thymeleaf use (mainly Code)

<li class="layui-nav-item layui-this" th:each="menu:${menus}">
    <a href="javascript:;" th:text="${menu.menuName}">系统管理</a>
    <ul class="layui-nav-child"  style="background: #2b2e37;">
         <li th:each="child:${menu.sonList}">
             <a th:if="${#lists.isEmpty(child.sonList)}" th:text="${child.menuName}" th:href="@{'/'+${child.menuUrl}}" href="javascript:;" style="margin-left: 20px;">用户管理</a>
         </li>
    </ul>
</li>
