zTree 是一个依靠 jQuery 实现的多功能 “树插件”。优异的性能、灵活的配置、多种功能的组合是 zTree 最大优点。

角色信息实体类：

package org.muses.jeeplatform.core.entity.admin;import javax.persistence.*;
import java.io.Serializable;
import java.util.HashSet;
import java.util.Set;/*** @description 角色信息实体类* @author Nicky* @date 2017年3月16日*/
@Table(name="sys_role")
@Entity
public class Role implements Serializable{/** 角色Id**/private int roleId;/** 角色描述**/private String roleDesc;/** 角色名称**/private String roleName;/** 角色标志**/private String role;private Set<Permission> permissions = new HashSet<Permission>();@Id@GeneratedValue(strategy=GenerationType.IDENTITY)public int getRoleId() {return roleId;}public void setRoleId(int roleId) {this.roleId = roleId;}@Column(length=100)public String getRoleDesc() {return roleDesc;}public void setRoleDesc(String roleDesc) {this.roleDesc = roleDesc;}@Column(length=100)public String getRoleName() {return roleName;}public void setRoleName(String roleName) {this.roleName = roleName;}@Column(length=100)public String getRole() {return role;}public void setRole(String role) {this.role = role;}//修改cascade策略为级联关系@OneToMany(targetEntity=Permission.class,cascade=CascadeType.MERGE,fetch=FetchType.EAGER)@JoinTable(name="sys_role_permission", joinColumns=@JoinColumn(name="roleId",referencedColumnName="roleId"), inverseJoinColumns=@JoinColumn(name="permissionId",referencedColumnName="id",unique=true))public Set<Permission> getPermissions() {return permissions;}public void setPermissions(Set<Permission> permissions) {this.permissions = permissions;}@Overridepublic boolean equals(Object obj) {if (obj instanceof Role) {Role role = (Role) obj;return this.roleId==(role.getRoleId())&& this.roleName.equals(role.getRoleName())&& this.roleDesc.equals(role.getRoleDesc())&& this.role.equals(role.getRole());}return super.equals(obj);}
}

权限信息实体类：

package org.muses.jeeplatform.core.entity.admin;import java.io.Serializable;
import java.util.HashSet;
import java.util.Set;import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToMany;
import javax.persistence.OneToOne;
import javax.persistence.Table;/*** @description 权限操作的Vo类* @author Nicky* @date 2017年3月6日*/
@Table(name="sys_permission")
@Entity
public class Permission implements Serializable {private int id;private String pdesc;private String name;private static final long serialVersionUID = 1L;private Menu menu;private Set<Operation> operations = new HashSet<Operation>();public Permission() {super();}@GeneratedValue(strategy = GenerationType.IDENTITY)@Idpublic int getId() {return this.id;}public void setId(int id) {this.id = id;}@Column(length=100)public String getPdesc() {return this.pdesc;}public void setPdesc(String pdesc) {this.pdesc = pdesc;}@Column(length=100)public String getName() {return this.name;}public void setName(String name) {this.name = name;}@OneToOne(targetEntity=Menu.class,cascade=CascadeType.REFRESH,fetch=FetchType.EAGER)@JoinColumn(name="menuId",referencedColumnName="menuId")public Menu getMenu() {return menu;}public void setMenu(Menu menu) {this.menu = menu;}@ManyToMany(targetEntity=Operation.class,cascade=CascadeType.MERGE,fetch=FetchType.EAGER)@JoinTable(name="sys_permission_operation",joinColumns=@JoinColumn(name="permissionId",referencedColumnName="id"),inverseJoinColumns=@JoinColumn(name="operationId",referencedColumnName="id"))public Set<Operation> getOperations() {return operations;}public void setOperations(Set<Operation> operations) {this.operations = operations;}
}

实现菜单信息实体类，用JPA来实现

package org.muses.jeeplatform.core.entity.admin;import javax.persistence.*;
import java.io.Serializable;
import java.util.List;/*** @description 菜单信息实体* @author Nicky* @date 2017年3月17日*/
@Table(name="sys_menu")
@Entity
public class Menu implements Serializable {/** 菜单Id**/private int menuId;/** 上级Id**/private int parentId;/** 菜单名称**/private String menuName;/** 菜单图标**/private String menuIcon;/** 菜单URL**/private String menuUrl;/** 菜单类型**/private String menuType;/** 菜单排序**/private String menuOrder;/**菜单状态**/private String menuStatus;private List<Menu> subMenu;private String target;private boolean hasSubMenu = false;public Menu() {super();}   @Id@GeneratedValue(strategy=GenerationType.IDENTITY)public int getMenuId() {return this.menuId;}public void setMenuId(int menuId) {this.menuId = menuId;}@Column(length=100)public int getParentId() {return parentId;}public void setParentId(int parentId) {this.parentId = parentId;}@Column(length=100)public String getMenuName() {return this.menuName;}public void setMenuName(String menuName) {this.menuName = menuName;}   @Column(length=30)public String getMenuIcon() {return this.menuIcon;}public void setMenuIcon(String menuIcon) {this.menuIcon = menuIcon;}   @Column(length=100)public String getMenuUrl() {return this.menuUrl;}public void setMenuUrl(String menuUrl) {this.menuUrl = menuUrl;}   @Column(length=100)public String getMenuType() {return this.menuType;}public void setMenuType(String menuType) {this.menuType = menuType;}@Column(length=10)public String getMenuOrder() {return menuOrder;}public void setMenuOrder(String menuOrder) {this.menuOrder = menuOrder;}@Column(length=10)public String getMenuStatus(){return menuStatus;}public void setMenuStatus(String menuStatus){this.menuStatus = menuStatus;}@Transientpublic List<Menu> getSubMenu() {return subMenu;}public void setSubMenu(List<Menu> subMenu) {this.subMenu = subMenu;}public void setTarget(String target){this.target = target;}@Transientpublic String getTarget(){return target;}public void setHasSubMenu(boolean hasSubMenu){this.hasSubMenu = hasSubMenu;}@Transientpublic boolean getHasSubMenu(){return hasSubMenu;}}

实现JpaRepository接口

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> {}

实现JpaRepository接口

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>{}

角色Service类：

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.*/
@Service
public class RolePageService {@AutowiredRolePageRepository roleRepository;/*** 构建PageRequest对象* @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);}/*** 获取所有的菜单信息并分页显示* @param pageNo*          当前页面数* @param pageSize*          每一页面的页数* @return*/public Page<Role> findAll(int pageNo, int pageSize, Sort.Direction dir, String str){PageRequest pageRequest = buildPageRequest(pageNo, pageSize, dir, str);Page<Role> roles = roleRepository.findAll(pageRequest);return roles;}public List<Role> findAllRole(){Iterable<Role> roles = roleRepository.findAll();List<Role> myList = Lists.newArrayList(roles);return myList;}/*** 根据角色id查找角色信息* @param roleId* @return*/public Role findByRoleId(String roleId){return roleRepository.findOne(Integer.parseInt(roleId));}/*** 保存角色信息* @param role*/public void doSave(Role role){roleRepository.save(role);}}

菜单Service类：

package org.muses.jeeplatform.service;import org.muses.jeeplatform.annotation.RedisCache;
import org.muses.jeeplatform.common.RedisCacheNamespace;
import org.muses.jeeplatform.core.dao.repository.admin.MenuTreeRepository;
import org.muses.jeeplatform.core.entity.admin.Menu;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;import java.util.List;/*** Created by Nicky on 2017/6/17.*/
@Service
public class MenuTreeService {@AutowiredMenuTreeRepository menuTreeRepository;/*** 查询所有的菜单* @return*/@Transactional//@RedisCachepublic List<Menu> findAll(){return menuTreeRepository.findAll();}}

在Controller类里通过角色id获取该角色可以查看的菜单：

/*** 跳转到角色授权页面* @param roleId* @param model* @return*/@RequestMapping(value = "/goAuthorise" )public String goAuth(@RequestParam String roleId, Model model){List<Menu> menuList = menuTreeService.findAll();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";}

在前端通过zTree实现树形菜单展示，通过勾选然后实现角色授权：
