SpringMVC ZTree實現樹形選單許可權配置的方法

SpringMVC ZTree實現樹形選單許可權配置的方法

計劃在開源專案里加入許可權配置的功能,打算加入zTree實現樹形結構。

Team的Github開源專案連結:https://github.com/u014427391/jeeplatform歡迎star(收藏)

zTree 是一個依靠 jQuery 實現的多功能 “樹外掛”。優異的效能、靈活的配置、多種功能的組合是 zTree 最大優點。

角色資訊實體類:


package org.muses.jeeplatform.core.entity.admin;
import javax.persistence.*;
import java.io.Serializable;
import java.util.HashSet;
import java.util.Set;
/**
* @description 角色資訊實體類

*/
@Table(name="sys_role")
@Entity
public class Role implements Serializable{
/** 角色Id**/
private int roleId;
/** 角色描述**/
private String roleDesc;
/** 角色名稱**/
private String roleName;
/** 角色標誌**/
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策略為級聯關係
@OneToMany(targetEntity=Permission.class,cascade=CascadeType.MERGE,fetch=FetchType.EAGER)
@JoinTable(name="sys_role_permission", [email protected](name="roleId",referencedColumnName="roleId"), [email protected](name="permissionId",referencedColumnName="id",unique=true))
public Set<Permission> getPermissions() {

@Override
public boolean equals(Object 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);
}
}

許可權資訊實體類:


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;
/**

* @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)
@Id
public int getId() {
return this.id;
}
public void setId(int id) {
this.id = id;
}
@Column(length=100)

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",[email protected](name="permissionId",referencedColumnName="id"),[email protected](name="operationId",referencedColumnName="id"))
public Set<Operation> getOperations() {
return operations;
}
public void setOperations(Set<Operation> operations) {
this.operations = operations;
}
}

實現選單資訊實體類,用JPA來實現


package org.muses.jeeplatform.core.entity.admin;
import javax.persistence.*;
import java.io.Serializable;
import java.util.List;
/**
* @description 選單資訊實體
* @author Nicky
* @date 2017年3月17日
*/
@Table(name="sys_menu")
@Entity
public class Menu implements Serializable {
/** 選單Id**/
private int menuId;  
/** 上級Id**/
private int parentId;  
/** 選單名稱**/
private String menuName;  
/** 選單圖示**/
private String menuIcon;  
/** 選單URL**/
private String menuUrl;  
/** 選單型別**/
private String menuType;
/** 選單排序**/
private String menuOrder;
/**選單狀態**/
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;
}
@Transient
public List<Menu> getSubMenu() {
return subMenu;
}
public void setSubMenu(List<Menu> subMenu) {
this.subMenu = subMenu;
}
public void setTarget(String target){
this.target = target;
}
@Transient
public String getTarget(){
return target;
}
public void setHasSubMenu(boolean hasSubMenu){
this.hasSubMenu = hasSubMenu;
}
@Transient
public boolean getHasSubMenu(){
return hasSubMenu;
}
}

實現JpaRepository介面


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> {
}

實現JpaRepository介面


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類:


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 {
@Autowired
RolePageRepository roleRepository;
/**
* 構建PageRequest物件
* @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);
}
/**
* 獲取所有的選單資訊並分頁顯示
* @param pageNo
*     當前頁面數
* @param pageSize
*     每一頁面的頁數
* @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;
}
/**
* 根據角色id查詢角色資訊
* @param roleId
* @return
*/
public Role findByRoleId(String roleId){
return roleRepository.findOne(Integer.parseInt(roleId));
}
/**
* 儲存角色資訊
* @param role
*/
public void doSave(Role role){
roleRepository.save(role);
}
}

選單Service類:


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 {
@Autowired
MenuTreeRepository menuTreeRepository;
/**
* 查詢所有的選單
* @return
*/
@Transactional
//@RedisCache
public List<Menu> findAll(){
return menuTreeRepository.findAll();
}
}

在Controller類裡通過角色id獲取該角色可以檢視的選單:


/**
* 跳轉到角色授權頁面
* @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";
}

在前端通過zTree實現樹形選單展示,通過勾選然後實現角色授權:
