计划在开源项目里加入权限配置的功能，打算加入zTree实现树形结构。

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 permissions = new HashSet();
@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 getPermissions() {
return permissions;
}
public void setPermissions(Set permissions) {
this.permissions = permissions;
}
@Override
public 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 operations = new HashSet();
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)
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 getOperations() {
return operations;
}
public void setOperations(Set 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 {
}
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{
}
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 {
@Autowired
RolePageRepository 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 findAll(int pageNo, int pageSize, Sort.Direction dir, String str){
PageRequest pageRequest = buildPageRequest(pageNo, pageSize, dir, str);
Page roles = roleRepository.findAll(pageRequest);
return roles;
}
public List findAllRole(){
Iterable roles = roleRepository.findAll();
List 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 {
@Autowired
MenuTreeRepository menuTreeRepository;
/**
* 查询所有的菜单
* @return
*/
@Transactional
//@RedisCache
public List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：
<%@ page contentType="text/html; charset=utf-8" pageEncoding="utf-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
