本文實例為大家分享了springboot+vue實現登錄功能的具體代碼，供大家參考，具體內容如下

目錄結構

前端端口：8080后端端口：8900

login.vue

<template> <div class='login_content'><!-- 登錄塊 --><div class='login_box'> <!-- 頭像 --> <div class='avatar_box'><img src='http://www.gepszalag.com/assets/logo.png'/> </div> <!-- 表單區域 --> <el-form ref='loginFormRef' :rules='loginRules' :model='loginForm' label-width='0'><!-- 用戶名 --><el-form-item prop='username'> <el-input v-model='loginForm.username' prefix-icon='iconfont icon-denglu'></el-input></el-form-item><!-- 密碼 --><el-form-item prop='password'> <el-input v-model='loginForm.password' prefix-icon='iconfont icon-mima' type='password'></el-input></el-form-item><!-- 按鈕 --><el-form-item class='btns'> <el-button type='primary' @click='login'>提交</el-button> <el-button type='info' @click='resetLoginFrom'>重置</el-button></el-form-item> </el-form></div> </div></template><script> export default {data(){ return {// 表單數據loginForm:{ username:'admin', password:'123456'},// 驗證對象loginRules:{ // 校驗用戶名 username:[{ required: true, message: ’用戶名為必填項’, trigger: ’blur’ },{ min: 5, max: 12, message: ’長度在 5 到 12 個字符’, trigger: ’blur’ } ], // 校驗密碼 password:[{ required: true, message: ’用戶密碼為必填項’, trigger: ’blur’ },{ min: 6, max: 10, message: ’長度在 6 - 10 個字符’, trigger: ’blur’ } ],}, }},methods:{ // 重置表單內容 resetLoginFrom(){this.$refs.loginFormRef.resetFields(); }, // 登錄方法 login(){// 1.表單驗證this.$refs.loginFormRef.validate(async valid =>{ if(!valid){return ; } // 表單驗證成功 const {data:res} = await this.$http.post('login',this.loginForm) // 訪問后臺地址 console.log(res) if( res.flag == 'ok'){this.$message.success('操作成功');// 跳轉到home頁面this.$router.push({path:'/home'});// 存儲user對象window.sessionStorage.setItem('user',res.user); }else{this.$message.error('操作失敗') }}); }} }</script><style lang='less' scoped> .login_content{background-color: #2b4b6b;height: 100%; } .login_box{height: 300px;width: 450px;background-color: #fff;border-radius: 3px;position: absolute;left: 50%;top: 50%;transform:translate(-50%,-50%);.avatar_box{ width: 130px; height: 130px; border: 1px solid #eee; border-radius: 50%; padding: 10px; box-shadow: 0 0 10px #ddd; position: absolute; left: 50%; transform:translate(-50%,-50%); background-color: #0ee; img{width: 100%;height: 100%;border-radius: 50%;background-color: #0ee; }} } .btns{display: flex;justify-content: flex-end; } .login_form{position: absolute;buttom:0%;width: 100%;padding: 0 10px;box-sizing: border-box;margin-top: 120px; }</style>

Home.vue

<template> <div><el-button type='info' @click='logout'>安全退出</el-button> </div></template><script> export default {methods:{ logout(){// 清楚sessionwindow.sessionStorage.clear();this.$router.push('/login'); }} }</script><style scoped></style>

index.js

import Vue from ’vue’import VueRouter from ’vue-router’// 引入login組件import Login from ’../components/login.vue’import Home from ’../components/Home.vue’Vue.use(VueRouter)const routes = [ {path:'/',redirect:'/login' }, {path:'/login',component:Login }, {path:'/home',component:Home },]const router = new VueRouter({ routes})// 掛載路由導航守衛router.beforeEach((to,from,next)=>{ // to將要訪問 // from 從哪訪問 // next 接著干next（url）重定向url上，繼續訪問to路徑 if(to.path==’/login’) return next(); // 獲取user const userFlag = window.sessionStorage.getItem('user'); // 無值返回登錄頁 if(!userFlag) return next(’/login’); // 符合要求，放行 next();})export default router

main.js

import Vue from ’vue’import App from ’./App.vue’import router from ’./router’import ’./plugins/element.js’// 添加全局樣式import ’./assets/css/global.css’// 引入icfontimport ’./assets/font/iconfont.css’// 導入aioxsimport axios from ’axios’// 掛載axiosVue.prototype.$http = axios// 設置訪問根路徑axios.defaults.baseURL='http://localhost:9000'Vue.config.productionTip = falsenew Vue({ router, render: h => h(App)}).$mount(’#app’)

后臺實現

@RestControllerpublic class LoginController { @Autowired UserDao userDao; @PostMapping('login') public String login(@RequestBody User user){String flag = 'fail';User user1 = userDao.getUserByMessage(user.getUsername(),user.getPassword());System.out.println('user'+user1);if(user1!=null){ flag='ok';}Map<String , Object> map = new HashMap<>();map.put('flag',flag);map.put('user',user);String param= JSON.toJSONString(map);return param; }}
