Ztree is a versatile "tree plugin" that relies on jQuery. The combination of excellent performance, flexible configuration and multiple functions is the biggest advantage of Ztree.

Implement the menu information entity class, implemented with JPA

Implementing the Jparepository Interface

package org.muses.jeeplatform.core.dao.repository.admin;import org.muses.jeeplatform.core.entity.admin.Role;import org.springframework.data.jpa.repository.JpaRepository;/** * Created by Nicky on 2017/12/2. */public interface RoleRepository extends JpaRepository<Role,Integer> {}

Implementing the Jparepository Interface

package org.muses.jeeplatform.core.dao.repository.admin;import org.muses.jeeplatform.core.entity.admin.Menu;import org.springframework.data.jpa.repository.JpaRepository;/** * Created by Nicky on 2017/6/17. */public interface MenuTreeRepository extends JpaRepository<Menu,Integer>{}

Role service class:

Package Org.muses.jeeplatform.service;import Com.google.common.collect.lists;import Org.muses.jeeplatform.core.dao.repository.admin.rolepagerepository;import Org.muses.jeeplatform.core.entity.admin.role;import org.springframework.beans.factory.annotation.Autowired; Import Org.springframework.data.domain.page;import Org.springframework.data.domain.pagerequest;import Org.springframework.data.domain.sort;import Org.springframework.stereotype.service;import java.util.List;/** * Created by Nicky on 2017/7/30.    */@Servicepublic class Rolepageservice {@Autowired rolepagerepository rolerepository;    /** * Build pagerequest Object * @param num * @param size * @param ASC * @param String * @return */  Private pagerequest buildpagerequest (int num, int size, sort.direction ASC, String    String) {return new Pagerequest (Num-1, size,null,string); }/** * Get all the menu information and page display * @param pageno * Current page number * @parAM pageSize * Number of pages per page * @return */public page<role> findAll (int pageno, int pageSize, Sort.

Menu Service class:

In the Controller class, get the menu that the role can view through the role ID:

/** * Jump to role Authorization page * @param roleid * @param model * @return */@RequestMapping (value = "/goauthorise" public string Goauth (@RequestParam string roleid, model model) {list<menu> menulist = menutreeservice.fi        Ndall ();        Role role = Roleservice.findbyroleid (Roleid);        Set<permission> haspermissions = null;        if (role = null) {haspermissions = Role.getpermissions (); } for (Menu m:menulist) {for (Permission p:haspermissions) {if (P.getmenu (). Getmenuid (                ) ==m.getmenuid ()) {M.sethassubmenu (true);        }}} model.addattribute ("Roleid", Roleid);        Jsonarray Jsonarray = Jsonarray.fromobject (menulist);        String json = jsonarray.tostring ();                JSON = Json.replaceall ("MenuId", "id"). ReplaceAll ("ParentID", "PId").        ReplaceAll ("MenuName", "name"). ReplaceAll ("Hassubmenu", "checked"); Model.addattribute ("menuS ", JSON);    return "Admin/role/role_auth"; }

The
