硅谷通用权限系统：菜单管理

一、菜单管理需求

1、需求描述

不同角色的用户登录后台管理系统拥有不同的菜单权限与功能权限，我们前端是基于：vue-admin-template这个模块开发的，因此我们菜单表设计也必须基于前端模板进行设计。

前端框架vue-admin-template菜单其实就是我们配置的路由：

{
  path: '/system',
  component: Layout,
  meta: {
    title: '系统管理',
    icon: 'el-icon-s-tools'
  },
  alwaysShow: true,
  children: [
    {
      name: 'sysUser',
      path: 'sysUser',
      component: () => import('@/views/system/sysUser/list'),
      meta: {
        title: '用户管理',
        icon: 'el-icon-s-custom'
      },
    },
    {
      path: 'sysRole',
      component: () => import('@/views/system/sysRole/list'),
      meta: {
        title: '角色管理',
        icon: 'el-icon-s-help'
      },
    },
    {
      name: 'sysMenu',
      path: 'sysMenu',
      component: () => import('@/views/system/sysMenu/list'),
      meta: {
        title: '菜单管理',
        icon: 'el-icon-s-unfold'
      },
    },
    {
      path: 'assignAuth',
      component: () => import('@/views/system/sysRole/assignAuth'),
      meta: {
        activeMenu: '/system/sysRole',
        title: '角色授权'
      },
      hidden: true,
    }
  ]
}

因此，菜单表的设计必须满足路由配置的必要信息

2、菜单表设计

2.1、表结构

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-sudR7LIU-1666693493779)(images/5.菜单管理/image-20220620092842446.png)]

重点字段说明：

type：菜单类型，分为：目录、菜单与按钮

目录：一个分类（可理解为一级菜单）、目录下级节点可以为目录与菜单

菜单：一个具体页面，菜单的下级节点只能是按钮

按钮：页面上的功能

path：对应路由里面的路由地址path

component：对应路由里面的组件component

perms：对应菜单的功能权限标识

icom：对应路由的菜单图标

2.2、示例数据

二、菜单管理

1、菜单管理CRUD

1.1、mapper

package com.atguigu.system.mapper;


import com.atguigu.model.system.SysMenu;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
@Mapper
public interface SysMenuMapper extends BaseMapper<SysMenu> {

}

1.2、service接口及实现

SysMenuService接口

package com.atguigu.system.service;


import com.atguigu.model.system.SysMenu;
import com.baomidou.mybatisplus.extension.service.IService;

import java.util.List;

public interface SysMenuService extends IService<SysMenu> {

    /**
     * 菜单树形数据
     * @return
     */
    List<SysMenu> findNodes();

}

SysMunuServiceImpl实现

package com.atguigu.system.service.impl;

import com.atguigu.common.execption.GuiguException;
import com.atguigu.common.result.ResultCodeEnum;
import com.atguigu.model.system.SysMenu;
import com.atguigu.system.helper.MenuHelper;
import com.atguigu.system.mapper.SysMenuMapper;
import com.atguigu.system.service.SysMenuService;
import com.baomidou.mybatisplus.core.conditions.query.LambdaQueryWrapper;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.util.CollectionUtils;

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

@Transactional
@Service
public class SysMenuServiceImpl extends ServiceImpl<SysMenuMapper, SysMenu> implements SysMenuService {

    @Autowired
    private SysMenuMapper sysMenuMapper;

    @Override
    public List<SysMenu> findNodes() {
        //全部权限列表
        List<SysMenu> sysMenuList = this.list();
        if (CollectionUtils.isEmpty(sysMenuList)) return null;

        //构建树形数据
        List<SysMenu> result = MenuHelper.buildTree(sysMenuList);
        return result;
    }

    @Override
    public boolean removeById(Serializable id) {
        int count = this.count(new QueryWrapper<SysMenu>().eq("parent_id", id));
        if (count > 0) {
            throw new GuiguException(ResultCodeEnum.NODE_ERROR);
        }
        sysMenuMapper.deleteById(id);
        return false;
    }

}

添加Menu帮助类

package com.atguigu.common.helper;


import com.atguigu.model.system.SysMenu;

import java.util.ArrayList;
import java.util.List;

/**
 * <p>
 * 根据菜单数据构建菜单树的工具类
 * </p>
 *
 */
public class MenuHelper {

    /**
     * 使用递归方法建菜单
     * @param sysMenuList
     * @return
     */
    public static List<SysMenu> buildTree(List<SysMenu> sysMenuList) {
        List<SysMenu> trees = new ArrayList<>();
        for (SysMenu sysMenu : sysMenuList) {
            if (sysMenu.getParentId().longValue() == 0) {
                trees.add(findChildren(sysMenu,sysMenuList));
            }
        }
        return trees;
    }

    /**
     * 递归查找子节点
     * @param treeNodes
     * @return
     */
    public static SysMenu findChildren(SysMenu sysMenu, List<SysMenu> treeNodes) {
        sysMenu.setChildren(new ArrayList<SysMenu>());

        for (SysMenu it : treeNodes) {
            if(sysMenu.getId().longValue() == it.getParentId().longValue()) {
                if (sysMenu.getChildren() == null) {
                    sysMenu.setChildren(new ArrayList<>());
                }
                sysMenu.getChildren().add(findChildren(it,treeNodes));
            }
        }
        return sysMenu;
    }
}

1.4、controller

package com.atguigu.system.controller;

import com.atguigu.common.result.Result;
import com.atguigu.model.system.SysMenu;
import com.atguigu.system.service.SysMenuService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.List;

@Api(tags = "菜单管理")
@RestController
@RequestMapping("/admin/system/sysMenu")
public class SysMenuController {

    @Autowired
    private SysMenuService sysMenuService;

    @ApiOperation(value = "获取菜单")
    @GetMapping("findNodes")
    public Result findNodes() {
        List<SysMenu> list = sysMenuService.findNodes();
        return Result.ok(list);
    }

    @ApiOperation(value = "新增菜单")
    @PostMapping("save")
    public Result save(@RequestBody SysMenu permission) {
        sysMenuService.save(permission);
        return Result.ok();
    }

    @ApiOperation(value = "修改菜单")
    @PutMapping("update")
    public Result updateById(@RequestBody SysMenu permission) {
        sysMenuService.updateById(permission);
        return Result.ok();
    }

    @ApiOperation(value = "删除菜单")
    @DeleteMapping("remove/{id}")
    public Result remove(@PathVariable Long id) {
        sysMenuService.removeById(id);
        return Result.ok();
    }

}

1.5、knife4j测试

http://localhost:8800/doc.html

2、菜单管理前端实现

2.1、添加路由

修改 src/router/index.js 文件

{
  name: 'sysMenu',
  path: 'sysMenu',
  component: () => import('@/views/system/sysMenu/list'),
  meta: {
    title: '菜单管理',
    icon: 'el-icon-s-unfold'
  },
}

2.2、定义基础api

创建文件 src/api/system/sysMenu.js

import request from '@/utils/request'

/*
菜单管理相关的API请求函数
*/
const api_name = '/admin/system/sysMenu'

export default {

  /*
  获取权限(菜单/功能)列表
  */
  findNodes() {
    return request({
      url: `${api_name}/findNodes`,
      method: 'get'
    })
  },

  /*
  删除
  */
  removeById(id) {
    return request({
      url: `${api_name}/remove/${id}`,
      method: "delete"
    })
  },

  /*
  保存
  */
  save(sysMenu) {
    return request({
      url: `${api_name}/save`,
      method: "post",
      data: sysMenu
    })
  },

  /*
  更新
  */
  updateById(sysMenu) {
    return request({
      url: `${api_name}/update`,
      method: "put",
      data: sysMenu
    })
  }
}

2.3、实现页面功能

创建src/views/system/sysMenu/list.vue

<template>
  <div class="app-container">

    <!-- 工具条 -->
    <div class="tools-div">
      <el-button type="success" icon="el-icon-plus" size="mini" @click="add()">添 加</el-button>
    </div>
    <el-table

      api.save(this.sysMenu).then(response => {
        this.$message.success(response.message || '操作成功')
        this.dialogVisible = false
        this.fetchData(this.page)
      })
    },

    //更新
    update() {
      api.updateById(this.sysMenu).then(response => {
        this.$message.success(response.message || '操作成功')
        this.dialogVisible = false
        this.fetchData()
      })
    }
  }
}
</script>

三、给角色分配权限

1、给角色分配权限

1.1、接口分析

1、进入分配页面：获取全部菜单及按钮，选中已选复选框，进行页面展示

2、保存分配权限：删除之前分配的权限和保存现在分配的权限

1.2、controller方法

操作类：SysMenuController

@ApiOperation(value = "根据角色获取菜单")
@GetMapping("/toAssign/{roleId}")
public Result toAssign(@PathVariable Long roleId) {
    List<SysMenu> list = sysMenuService.findSysMenuByRoleId(roleId);
    return Result.ok(list);
}

@ApiOperation(value = "给角色分配权限")
@PostMapping("/doAssign")
public Result doAssign(@RequestBody AssginMenuVo assginMenuVo) {
    sysMenuService.doAssign(assginMenuVo);
    return Result.ok();
}

1.3、service接口

操作类：SysMenuService

/**
 * 根据角色获取授权权限数据
 * @return
 */
List<SysMenu> findSysMenuByRoleId(Long roleId);

/**
 * 保存角色权限
 * @param  assginMenuVo
 */
void doAssign(AssginMenuVo assginMenuVo);

1.4、service接口实现

1、操作类：SysMenuServiceImpl

@Autowired
private SysRoleMenuMapper sysRoleMenuMapper;

@Override
public List<SysMenu> findSysMenuByRoleId(Long roleId) {
    //获取所有status为1的权限列表
    List<SysMenu> menuList = sysMenuMapper.selectList(new QueryWrapper<SysMenu>().eq("status", 1));
    //根据角色id获取角色权限
    List<SysRoleMenu> roleMenus = sysRoleMenuMapper.selectList(new QueryWrapper<SysRoleMenu>().eq("role_id",roleId));
    //获取该角色已分配的所有权限id
    List<Long> roleMenuIds = new ArrayList<>();
    for (SysRoleMenu roleMenu : roleMenus) {
        roleMenuIds.add(roleMenu.getMenuId());
    }
    //遍历所有权限列表
    for (SysMenu sysMenu : menuList) {
        if(roleMenuIds.contains(sysMenu.getId())){
            //设置该权限已被分配
            sysMenu.setSelect(true);
        }else {
            sysMenu.setSelect(false);
        }
    }
    //将权限列表转换为权限树
    List<SysMenu> sysMenus = MenuHelper.buildTree(menuList);
    return sysMenus;
}

@Override
public void doAssign(AssginMenuVo assginMenuVo) {
    //删除已分配的权限
    sysRoleMenuMapper.delete(new QueryWrapper<SysRoleMenu>().eq("role_id",assginMenuVo.getRoleId()));
    //遍历所有已选择的权限id
    for (Long menuId : assginMenuVo.getMenuIdList()) {
        if(menuId != null){
            //创建SysRoleMenu对象
            SysRoleMenu sysRoleMenu = new SysRoleMenu();
            sysRoleMenu.setMenuId(menuId);
            sysRoleMenu.setRoleId(assginMenuVo.getRoleId());
            //添加新权限
            sysRoleMenuMapper.insert(sysRoleMenu);
        }
    }
}

2、添加SysRoleMenuMapper

package com.atguigu.system.mapper;

import com.atguigu.model.system.SysRoleMenu;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;

@Repository
@Mapper
public interface SysRoleMenuMapper extends BaseMapper<SysRoleMenu> {

}

2、前端实现

2.1、添加路由

修改 src/router/index.js 文件

{
  path: 'assignAuth',
  component: () => import('@/views/system/sysRole/assignAuth'),
  meta: {
    activeMenu: '/system/sysRole',
    title: '角色授权'
  },
  hidden: true,
}

2.2、角色列表添加按钮及方法

操作文件 src/views/system/sysRole/list.vue

<el-button type="warning" icon="el-icon-baseball" size="mini" @click="showAssignAuth(scope.row)" title="分配权限"/>

showAssignAuth(row) {
  this.$router.push('/system/assignAuth?id='+row.id+'&roleName='+row.roleName);
}

2.3、添加api

创建文件 src/api/system/sysMenu.js

/*
查看某个角色的权限列表
*/
toAssign(roleId) {
  return request({
    url: `${api_name}/toAssign/${roleId}`,
    method: 'get'
  })
},

/*
给某个角色授权
*/
doAssign(assginMenuVo) {
  return request({
    url: `${api_name}/doAssign`,
    method: "post",
    data: assginMenuVo
  })
}

2.4、实现页面功能

创建src/views/system/sysRole/assignAuth.vue

<template>
  <div class="app-container">
    <div style="padding: 20px 20px 0 20px;">
      授权角色：{{ $route.query.roleName }}
    </div>
    <el-tree
      style="margin: 20px 0"
      ref="tree"
      :data="sysMenuList"
      node-key="id"
      show-checkbox
      default-expand-all
      :props="defaultProps"
    />
    <div style="padding: 20px 20px;">
      <el-button :loading="loading" type="primary" icon="el-icon-check" size="mini" @click="save">保存</el-button>
      <el-button @click="$router.push('/system/sysRole')" size="mini" icon="el-icon-refresh-right">返回</el-button>
    </div>
  </div>
</template>
<script>
  import api from '@/api/system/sysMenu'
  export default {
    name: 'roleAuth',

    data() {
      return {
        loading: false, // 用来标识是否正在保存请求中的标识, 防止重复提交
        sysMenuList: [], // 所有
        defaultProps: {
          children: 'children',
          label: 'name'
        },
      };
    },

    created() {
      this.fetchData()
    },

    methods: {
      /*
      初始化
      */
      fetchData() {
        const roleId = this.$route.query.id
        api.toAssign(roleId).then(result => {
          const sysMenuList = result.data
          this.sysMenuList = sysMenuList
          const checkedIds = this.getCheckedIds(sysMenuList)
          console.log('getPermissions() checkedIds', checkedIds)
          this.$refs.tree.setCheckedKeys(checkedIds)
        })
      },

      /*
      得到所有选中的id列表
      */
      getCheckedIds (auths, initArr = []) {
        return auths.reduce((pre, item) => {
          if (item.select && item.children.length === 0) {
            pre.push(item.id)
          } else if (item.children) {
            this.getCheckedIds(item.children, initArr)
          }
          return pre
        }, initArr)
      },

      /*
      保存权限列表
      */
      save() {
        debugger
        //获取到当前子节点
        //const checkedNodes = this.$refs.tree.getCheckedNodes()
        //获取到当前子节点及父节点
        const allCheckedNodes = this.$refs.tree.getCheckedNodes(false, true);
        let idList = allCheckedNodes.map(node => node.id);
        console.log(idList)
        let assginMenuVo = {
          roleId: this.$route.query.id,
          menuIdList: idList
        }
        this.loading = true
        api.doAssign(assginMenuVo).then(result => {
          this.loading = false
          this.$message.success(result.$message || '分配权限成功')
          this.$router.push('/system/sysRole');
        })
      }
    }
  };
