spring boot security jwt 整合vue-admin-template

首先感謝PanJiaChen 的 vue-admin-template 模板，我是一名java程序員，因此前端的技術不怎麼樣。vue.js也只是會用一點，很是感謝PanJiaChen 的模板支持。javascript

已經整合好的模板地址：https://github.com/thousmile/...css

若是你們以爲寫的不錯，就請點亮我GitHub的心心。很是感謝！html

若是你們在搭建過程當中遇到問題，歡迎找我前端

先從數據庫開始

大部分的權限管理系統都是5張表結構（一樣咱們這裏也採用這種方式）webpack

t_sys_user -----> t_sys_user_role -----> t_sys_role -----> t_sys_role_permission ----> t_sys_permission

這裏咱們主要看權限表（t_sys_permission ）ios

最重要的就是resources和type字段，這兩個字段在後面和vue.js整合的時候會用到，git

type字段，只有兩個類型，是按鈕仍是菜單

下面開始spring boot 工程的搭建 POM文件的主要依賴

而後在application.yml文件中添加jwt的配置

jwt: 
  header: jwtHeader   #jwt的請求頭
  secret: eyJleHAiOjE1NDMyMDUyODUsInN1YiI6ImFkbWluIiwiY3Jl   #jwt的加密字符串
  expiration: 3600000   #jwt token有效時間（毫秒）
  route:
    login: /auth/login    #登陸地址
    refresh: /auth/refresh  #刷新token地址
    register: /auth/register  #註冊的地址

JwtUser類顯示spring security 規定的 UserDetails 接口

public class JwtUser implements UserDetails {

    private String username;

    private String password;

    private Integer state;

    private Collection<? extends GrantedAuthority> authorities;

    public JwtUser() {
    }

    public JwtUser(String username, String password, Integer state, Collection<? extends GrantedAuthority> authorities) {
        this.username = username;
        this.password = password;
        this.state = state;
        this.authorities = authorities;
    }

    @Override
    public String getUsername() {
        return username;
    }

    @JsonIgnore
    @Override
    public String getPassword() {
        return password;
    }

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return authorities;
    }

    @JsonIgnore
    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    @JsonIgnore
    @Override
    public boolean isAccountNonLocked() {
        return state == 1;
    }

    @JsonIgnore
    @Override

登陸刷新token的Controller

package com.ifsaid.admin.controller;

import com.ifsaid.admin.service.ISysUserService;
import com.ifsaid.admin.vo.Result;
import org.apache.commons.lang3.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.Map;

/**
 * @author: Wang Chen Chen
 * @Date: 2018/10/29 10:49
 * @describe：
 * @version: 1.0
 */

@RestController
public class AuthController {

    @Autowired
    private ISysUserService sysUserService;

    @PostMapping(value = "${jwt.route.login}")
    public Result<String> login(@RequestBody Map<String, String> map) {
        String username = map.get("username");
        String password = map.get("password");
        if (StringUtils.isEmpty(username) || StringUtils.isEmpty(password)) {
            return Result.error401("用戶或者密碼不能爲空！", null);
        }
        return Result.success("登陸成功", sysUserService.login(username, password));
    }

    @PostMapping(value = "${jwt.route.refresh}")
    public Result<String> refresh(@RequestHeader("${jwt.header}") String token) {
        return Result.success("刷新token成功!", sysUserService.refreshToken(token));
    }

}

到這裏咱們已經獲取到 token。

而後根據token獲取獲取用戶信息

能夠劃分爲三個主要部分

1.用戶信息

2.菜單列表（遞歸形式）

3.按鈕列表（List列表形式）

而後開始整合vue-element-admin

先看一下成果。

從GitHub上面拉去vue-element-admin

# 克隆項目
git clone https://github.com/PanJiaChen/vue-admin-template.git

# 建議不要用cnpm  安裝有各類詭異的bug 能夠經過以下操做解決npm速度慢的問題
npm install --registry=https://registry.npm.taobao.org

# Serve with hot reload at localhost:9528
npm run dev

1.改登陸的api接口指向咱們spring boot 的登陸 目錄 /src/api/login.js

import request from '@/utils/request'

// 登陸
export function login(username, password) {
  return request({ url: '/auth/login', method: 'post', data: { username, password }})
}

// 獲取用戶信息
export function getInfo(token) {
  return request({ url: 'user/info', method: 'get' })
}

// 登出
export function logout() {
  return request({ url: 'user/logout', method: 'post' })
}

2.改axios的配置目錄 /src/utils/request.js

import axios from 'axios'
import { Message, MessageBox } from 'element-ui'
import store from '../store'
import { getToken } from '@/utils/auth'

// 建立axios實例
const service = axios.create({
  baseURL: process.env.BASE_API, // api 的 base_url
  timeout: 5000 // 請求超時時間
})

// request攔截器
service.interceptors.request.use(
  config => {
    if (getToken() !== '') {
      config.headers['jwtHeader'] = getToken() // 讓每一個請求攜帶自定義token 請根據實際狀況自行修改
    }
    return config
  },
  error => {
    // Do something with request error
    console.log(error) // for debug
    Promise.reject(error)
  }
)

// response 攔截器
service.interceptors.response.use(
  response => {
    /**
     * code爲非20000是拋錯 可結合本身業務進行修改
     */
    const res = response.data
    if (res.status !== 200) {
      Message({
        message: res.message,
        type: 'error',
        duration: 5 * 1000
      })

      // 50008:非法的token; 50012:其餘客戶端登陸了;  50014:Token 過時了;
      if (res.code === 400 || res.code === 401 || res.code === 402) {
        MessageBox.confirm('你已被登出，能夠取消繼續留在該頁面，或者從新登陸', '肯定登出',
          { confirmButtonText: '從新登陸',
            cancelButtonText: '取消',
            type: 'warning'
          }
        ).then(() => {
          store.dispatch('FedLogOut').then(() => {
            location.reload() // 爲了從新實例化vue-router對象 避免bug
          })
        })
      }
      return Promise.reject('error')
    } else {
      return response.data
    }
  },
  error => {
    console.log('err' + error) // for debug
    Message({
      message: error.message,
      type: 'error',
      duration: 5 * 1000
    })
    return Promise.reject(error)
  }
)

export default service

3.改/config/dev.env.js 和/config/prod.env.js

// dev.env.js

'use strict'
const merge = require('webpack-merge')
const prodEnv = require('./prod.env')

module.exports = merge(prodEnv, {
  NODE_ENV: '"development"',
  BASE_API: '"http://localhost:8080"',
})



// prod.env.js

'use strict'
module.exports = {
  NODE_ENV: '"production"',
  BASE_API: '"http://localhost:8080"',
}

4.改vuex 設置token的登陸，和獲取用戶信息目錄 /src/store/modules/user.js

import { login, logout, getInfo } from '@/api/login'
import { getToken, setToken, removeToken } from '@/utils/auth'

const user = {
  state: {
    token: getToken(),
    nickname: '',
    avatar: '',
    uid: '',
    user: {},
    roles: [],
    menus: [], // 菜單權限
    buttons: [] // 安裝權限
  },

  mutations: {
    SET_TOKEN: (state, token) => {
      state.token = token

    SET_INFO: (state, user) => {
      state.nickname = user.nickname
      state.avatar = user.avatar
      state.uid = user.uid
      state.user = user
    },
    SET_ROLES: (state, roles) => {
      state.roles = roles
    },
    SET_MENUS: (state, menus) => {
      state.menus = menus
    },
    SET_BUTTONS: (state, buttons) => {
      state.buttons = buttons
    }
  },

  actions: {
    // 登陸
    Login({ commit }, userInfo) {
      const username = userInfo.username.trim()
      return new Promise((resolve, reject) => {
        login(username, userInfo.password).then(res => {
          setToken(res.data)
          commit('SET_TOKEN', res.data)
          resolve()
        }).catch(error => {
          reject(error)
        })
      })
    },

    // 獲取用戶信息
    GetInfo({ commit, state }) {
      return new Promise((resolve, reject) => {
        getInfo(state.token).then(res => {
          const data = res.data
          if (data.roles && data.roles.length > 0) { // 驗證返回的roles是不是一個非空數組
            commit('SET_ROLES', data.roles)
          } else {
            reject('getInfo: roles must be a non-null array !')
          }
          commit('SET_MENUS', data.menus)
          commit('SET_BUTTONS', data.buttons)
          // 設置用戶信息
          commit('SET_INFO', data)
          resolve(res)
        }).catch(error => {
          reject(error)
        })
      })
    },

    // 登出
    LogOut({ commit, state }) {
      return new Promise((resolve, reject) => {
        logout(state.token).then(() => {
          commit('SET_INFO', '')
          commit('SET_TOKEN', '')
          commit('SET_ROLES', [])
          removeToken()
          resolve()

        commit('SET_TOKEN', '')
        removeToken()
        resolve()
      })
    }
  }
}

export default user

5.改vue router 目錄 /src/router/index.js

import Vue from 'vue'
import Router from 'vue-router'

Vue.use(Router)

import Layout from '@/views/layout/Layout'
// 默認的路由鏈。全部用戶公共的路由
export const constantRouterMap = [
  {
    path: '/login',
    name: 'Login',
    component: () =>
      import('@/views/login/index'),
    hidden: true
  },

  {
    path: '/',
    component: Layout,
    redirect: '/dashboard',
    name: 'Dashboard',
    hidden: true,
    children: [{
      path: 'dashboard',
      component: () =>
        import('@/views/dashboard/index')
    }, {
      path: 'userinfo',
      name: 'UserInfo',
      component: () =>
        import('@/views/dashboard/userinfo')
    }]
  },

  {
    path: '/error',
    component: Layout,
    redirect: '/error/404',
    hidden: true,
    children: [{
      path: '404',
      component: () =>
        import('@/views/error/404/index')
    }, {
      path: '401',
      component: () =>
        import('@/views/error/401/index')
    }]
  },
  {
    path: '*',
    redirect: '/error/404',
    hidden: true
  }
]

export default new Router({
  // mode: 'history', //後端支持可開
  scrollBehavior: () => ({ y: 0 }),
  routes: constantRouterMap
})

// 異步掛載的路由
// 動態須要根據權限加載的路由表
// 這個路由鏈，根據數據庫中的一一對應，也就是說這是一個最完整的路由鏈，
// 根據登陸的用戶權限的不一樣，而後從中提取出對應當前用戶的路由添加到vue router中
// meta:屬性中resources屬性最爲重要，用meta.resources和咱們獲取用戶信息中menus.resources匹配
export const asyncRouterMap = [
  {
    path: '/pre',
    component: Layout,
    name: 'pre',
    meta: {
      resources: 'pre',
      title: '權限管理'
    },
    children: [
      {
        path: 'index',
        component: () => import('@/views/pre/perm/index'),
        name: 'perm',
        meta: {
          resources: 'perm'
        }
      },
      {
        path: 'user',
        component: () => import('@/views/pre/user/index'),
        name: 'user',
        meta: {
          resources: 'user'
        }
      },
      {
        path: 'role',
        component: () => import('@/views/pre/role/index'),
        name: 'role',
        meta: {
          resources: 'role'
        }
      },
      {
        path: 'dept',
        component: () => import('@/views/pre/dept/index'),
        name: 'dept',
        meta: {
          resources: 'dept'
        }
      }
    ]
  },

  {
    path: '/sys',
    component: Layout,
    name: 'sys',
    meta: {
      resources: 'sys',
      title: '系統設置'
    },
    children: [
      {
        path: 'index',
        component: () => import('@/views/sys/backstage/index'),
        name: 'backstage',
        meta: {
          resources: 'backstage'
        }
      },
      {
        path: 'wechat',
        component: () => import('@/views/sys/wechat/index'),
        name: 'wechat',
        meta: {
          resources: 'wechat'
        }
      }
    ]
  },

  {
    path: 'external-link',
    component: Layout,
    name: 'Link',
    meta: {
      resources: 'control',
      title: '系統監控',
      icon: 'link'
    },
    children: [{
      path: 'https://www.baidu.com/',
      meta: {
        resources: 'logs',
        title: '系統日誌',
        icon: 'link'
      }
    },
    {
      path: 'https://v.qq.com/',
      meta: {
        resources: 'database',
        title: '數據庫監控',
        icon: 'link'
      }
    }
    ]
  }

]

6.添加權限管理，而且添加vuex中** 目錄 /src/store/modules/permission.js

// store/permission.js
import { asyncRouterMap, constantRouterMap } from '@/router'

/**
 *
 * @param  {Array} userRouter 後臺返回的用戶權限json
 * @param  {Array} allRouter  前端配置好的全部動態路由的集合
 * @return {Array} realRoutes 過濾後的路由
 */

export function recursionRouter(userRouter = [], allRouter = []) {
  var realRoutes = []
  allRouter.forEach((v, i) => {
    userRouter.forEach((item, index) => {
      if (item.resources === v.meta.resources) {
        if (item.children && item.children.length > 0) {
          v.children = recursionRouter(item.children, v.children)
        }
        v.meta.title = item.title
        v.meta.icon = item.icon
        realRoutes.push(v)
      }
    })
  })
  return realRoutes
}

/**
*
* @param {Array} routes 用戶過濾後的路由
*
* 遞歸爲全部有子路由的路由設置第一個children.path爲默認路由
*/
export function setDefaultRoute(routes) {
  routes.forEach((v, i) => {
    if (v.children && v.children.length > 0) {
      v.redirect = { name: v.children[0].name }
      setDefaultRoute(v.children)
    }
  })
}

const permission = {
  state: {
    routers: constantRouterMap, // 這是默認權限列表 好比404 500等路由
    dynamicRouters: [] // 這是經過後臺獲取的權利列表
  },
  mutations: {
    SET_ROUTERS: (state, routers) => {
      state.dynamicRouters = routers
      state.routers = constantRouterMap.concat(routers)
    }
  },
  actions: {
    GenerateRoutes({ commit }, data) {
      return new Promise(resolve => {
          // 把傳進來的menus 列表。用recursionRouter方法進行遞歸遍歷出來，存入vuex中
        commit('SET_ROUTERS', 。(data, asyncRouterMap))
        resolve()
      })
    }
  }
}

export default permission

7.修改/src/permission.js文件，修改路由調整的條件

import router from './router'
import store from './store'
import NProgress from 'nprogress' // Progress 進度條
import 'nprogress/nprogress.css'// Progress 進度條樣式
import { Message } from 'element-ui'
import { getToken } from '@/utils/auth' // 驗權

const whiteList = ['/login'] // 不重定向白名單
router.beforeEach((to, from, next) => {
  NProgress.start()
  if (getToken()) {
    if (to.path === '/login') {
      next({ path: '/' })
      NProgress.done() // if current page is dashboard will not trigger    afterEach hook, so manually handle it
    } else {
      if (store.getters.menus.length === 0) {
        // 拉取用戶信息(請確保在 GetInfo 方法中 已經獲取到菜單列表)
        store.dispatch('GetInfo').then(res => {
          // 動態設置路由（把上一步獲取到的用戶傳遞給 GenerateRoutes方法 解析）
          store.dispatch('GenerateRoutes', store.getters.menus).then(r => {
            // 獲取已經解析好的路由列表，動態添加到router中
            router.addRoutes(store.getters.dynamicRouters)
            // hack方法 確保addRoutes已完成
            next({ ...to, replace: true })
          })
        }).catch((err) => {
          store.dispatch('FedLogOut').then(() => {
            Message.error(err || 'Verification failed, please login again')
            next({ path: '/' })
          })
        })
      } else {
        next()
      }
    }
  } else {
    if (whiteList.indexOf(to.path) !== -1) {
      next()
    } else {
      next(`/login?redirect=${to.path}`) // 不然所有重定向到登陸頁
      NProgress.done()
    }
  }
})

router.afterEach(() => {
  NProgress.done() // 結束Progress
})

8.修改菜單渲染的方式，默認是從vue router中讀取路由鏈，而後渲染，可是咱們如今的路由鏈存在vuex中，

目錄: /src/views/layout/components/Sidebar/index.vue

<template>
  <el-scrollbar wrap-class="scrollbar-wrapper">

    <logo :is-collapse="isCollapse"/>

    <el-menu
      :show-timeout="200"
      :default-active="$route.path"
      :collapse="isCollapse"
      mode="vertical"
      background-color="#304156"
      text-color="#bfcbd9"
      active-text-color="#409EFF"
    >
      
           <!-- 主要就是在這裏位置  menu_routers -->
      <sidebar-item v-for="route in menu_routers" :key="route.path" :item="route" :base-path="route.path"/>
    </el-menu>
  </el-scrollbar>
</template>

<script>
import { mapGetters } from 'vuex'
import SidebarItem from './SidebarItem'
import logo from './Logo'

export default {
  components: {
    SidebarItem,
    logo
  },
  computed: {
      // 在這裏從vuex 中獲取到菜單列表
    ...mapGetters([
      'menu_routers',
      'sidebar'
    ]),
    isCollapse() {
      return !this.sidebar.opened
    }
  }
}
</script>

到如今爲止已經作到動態的菜單了，還剩按鈕的權限，按鈕比較簡單，添加一個vue 的指令便可

import Vue from 'vue'
import store from '@/store'

/** 權限指令**/

Vue.directive('has', {
  bind: function(el, binding) {
    if (!Vue.prototype.$_has(binding.value)) {
      el.parentNode.removeChild(el)
    }
  }
})

// 權限檢查方法
Vue.prototype.$_has = function(value) {
  // 獲取用戶按鈕權限
  let isExist = false
  const dynamicButtons = store.getters.buttons
  if (dynamicButtons === undefined || dynamicButtons === null || dynamicButtons.length < 1) {
    return isExist
  }
  dynamicButtons.forEach(button => {
    if (button.resources === value) {
      isExist = true
      return isExist
    }
  })
  return isExist
}

在頁面中測試一下指令是否好用

<!-- v-has中的值就是咱們獲取用戶信息時buttons的resources屬性。進行對比， -->

<el-button v-has="'perm:new'" class="btns">添加</el-button>

<el-button v-has="'perm:haha'" class="btns">哈哈</el-button>

到了這裏已經完成了 spring boot ，security ，jwt，vue-admin-template的整合一個完整的先後端分類，動態權限，控制到按鈕的後臺管理系統就完成了

若是你們以爲寫的不錯，就請點亮我GitHub的心心。很是感謝！
