1.添加element-ui模块
npm install element-ui -S
注:
npm install -g/-S/-D -g 将依赖下载到node_global -s 将依赖下载到当前项目中,并且在后续前端项目打包的时候,npm build的时候会一并打包到项目中 -d 将依赖下载到当前项目中,并且在后续前端项目打包的时候,npm build的时候不会打包到项目中
无报错,表示执行成功
在package.json中,可以看到添加element-ui
2.配置项目
参考官网: https://element.eleme.cn/#/zh-CN/component/quickstart
2.1.在config/main.js中写入以下内容
// The Vue build version to load with the `import` command // (runtime-only or standalone) has been set in webpack.base.conf with an alias. import Vue from 'vue' import App from './App' import ElementUI from 'element-ui'; import 'element-ui/lib/theme-chalk/index.css'; import router from './router' Vue.use(ElementUI); Vue.config.productionTip = false /* eslint-disable no-new */ new Vue({ el: '#app', router, components: { App }, template: '<App/>' })
2.2.测试是否引入成功
在App.vue中找到官网上组件分类的任意一个测试是否能正常使用,以Button按钮为例
<el-row> <el-button>默认按钮</el-button> <el-button type="primary">主要按钮</el-button> <el-button type="success">成功按钮</el-button> <el-button type="info">信息按钮</el-button> <el-button type="warning">警告按钮</el-button> <el-button type="danger">危险按钮</el-button> </el-row>
出现一排按钮表示成功
3.Axios前后端交互
3.1.在src的目录下,添加views目录,新建Login.vue
<template> <div class="login-wrap"> <el-form class="login-container"> <h1 class="title">用户登录</h1> <el-form-item label=""> <el-input type="text" v-model="username" placeholder="登录账号" autocomplete="off"></el-input> </el-form-item> <el-form-item label=""> <el-input type="password" v-model="password" placeholder="登录密码" autocomplete="off"></el-input> </el-form-item> <el-form-item> <el-button type="primary" style="width:100%;" @click="doSubmit()">提交</el-button> </el-form-item> <el-row style="text-align: center;margin-top:-10px"> <el-link type="primary">忘记密码</el-link> <el-link type="primary" @click="gotoRegister()">用户注册</el-link> </el-row> </el-form> </div> </template> <script> export default { name: "Login" } </script> <style scoped> .login-wrap { box-sizing: border-box; width: 100%; height: 100%; padding-top: 10%; background-image: url(data:image/svg+xml;base64,<?xml version="1.0" encoding="UTF-8" standalone="no"?>

3.2.配置路由
在router/index.js中修改vue项目默认显示路由
3.3.修改项目运行端口并启动
'use strict' // Template version: 1.3.1 // see http://vuejs-templates.github.io/webpack for documentation. const path = require('path') module.exports = { dev: { // Paths assetsSubDirectory: 'static', assetsPublicPath: '/', proxyTable: {}, // Various Dev Server settings host: 'localhost', // can be overwritten by process.env.HOST port: 8081, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined autoOpenBrowser: false, errorOverlay: true, notifyOnErrors: true, poll: false, // https://webpack.js.org/configuration/dev-server/#devserver-watchoptions- /** * Source Maps */ // https://webpack.js.org/configuration/devtool/#development devtool: 'cheap-module-eval-source-map', // If you have problems debugging vue-files in devtools, // set this to false - it *may* help // https://vue-loader.vuejs.org/en/options.html#cachebusting cacheBusting: true, cssSourceMap: true }, build: { // Template for index.html index: path.resolve(__dirname, '../dist/index.html'), // Paths assetsRoot: path.resolve(__dirname, '../dist'), assetsSubDirectory: 'static', assetsPublicPath: '/', /** * Source Maps */ productionSourceMap: true, // https://webpack.js.org/configuration/devtool/#production devtool: '#source-map', // Gzip off by default as many popular static hosts such as // Surge or Netlify already gzip all static assets for you. // Before setting to `true`, make sure to: // npm install --save-dev compression-webpack-plugin productionGzip: false, productionGzipExtensions: ['js', 'css'], // Run the build command with an extra argument to // View the bundle analyzer report after build finishes: // `npm run build --report` // Set to `true` or `false` to always turn it on or off bundleAnalyzerReport: process.env.npm_config_report } }
启动看到如下图所示

4.2安装Axios
axios是vue2提倡使用的轻量版的ajax。它是基于promise的HTTP库。它会从浏览器中创建XMLHttpRequests，与Vue配合使用非常好。
题外话：vue.js有著名的全家桶系列：vue-router，vuex， vue-resource，再加上构建工具vue-cli，就是一个完整的vue项目的核心构成。 其中vue-resource是Vue.js的一款插件，它可以通过XMLHttpRequest或JSONP发起请求并处理响应，但在vue更新到2.0之后，作者就宣告不再对vue-resource更新，而是推荐的axios
npm i axios -S
4.3axios之get
使用axios的get请求方式，必须将请求参数保存到json对象的params属性中。
修改Login.vue中的代码
<script> import axios from 'axios' export default { name: "Login", data: function() { return { username: "admin", password: "123" } }, methods: { doSubmit: function() { let params = { username: this.username, password: this.password }; console.log(params); var url = "http://localhost:8080/ssm/user/userLogin"; axios.get(url, { //注意数据是保存到json对象的params属性 params: params }).then(function(response) { console.log(response); }).catch(function(error) { console.log(error); }); } } } </script>
4.4.axios之post
安装qs库
npm install qs -S
使用axios的post请求方式，直接将请求参数保存到json对象中即可。
<script> import axios from 'axios' import qs from 'qs' export default { name: 'Login', data: function() { return { username: "admin", password: "123" } }, methods: { doSubmit: function() { let params = { username: this.username, password: this.password }; console.log(params); var url = "http://localhost:8080/ssm/user/userLogin"; //通过qs中的stringify方法进行格式转换 let str=qs.stringify(params); //注意数据是保存到json对象的params属性 axios.post(url, str).then(function(response) { console.log(response); }).catch(function(error) { console.log(error); }); } } } </script>
效果
4.5.vue-axios
Axios是一个基于Promise 用于浏览器和 nodejs 的 HTTP 客户端，本质上也是对原生XHR的封装，只不过它是Promise的实现版本，符合最新的ES规范。
vue-axios是在axios基础上扩展的插件，在Vue.prototype原型上扩展了$http等属性，可以更加方便的使用axios。
通过vue-axios实现对axios的轻量封装：
4.5.1.下载安装vue-axios
npm i vue-axios -S
4.5.2.导入api模块，添加axios的全局配置
将api模块导入到SPA项目的src目录下，其中api模块包含了action.js（针对后台请求接口的封装定义）和http.js（针对axios的全局配置）两个文件。
- action.js
/** * 对后台请求的地址的封装，URL格式如下： * 模块名_实体名_操作 */ export default { 'SERVER': 'http://localhost:8080/ssm', //服务器 'SYSTEM_USER_DOLOGIN': '/user/userLogin', //用户登陆 'getFullPath': k => { //获得请求的完整地址，用于mockjs测试时使用 return this.SERVER + this[k]; } }
对后台请求的地址的封装，URL格式：模块名_实体名_操作
- http.js
/** * vue项目对axios的全局配置 */ import axios from 'axios' import qs from 'qs' //引入action模块，并添加至axios的类属性urls上 import action from '@/api/action' axios.urls = action // axios默认配置 axios.defaults.timeout = 10000; // 超时时间 // axios.defaults.baseURL = 'http://localhost:8080/ssm'; // 默认地址 axios.defaults.baseURL = action.SERVER; //整理数据 // 只适用于 POST,PUT,PATCH，transformRequest` 允许在向服务器发送前，修改请求数据 axios.defaults.transformRequest = function(data) { data = qs.stringify(data); return data; }; // 请求拦截器 axios.interceptors.request.use(function(config) { // var jwt = window.vm.$store.getters.getJwt; // config.headers['jwt'] = jwt; return config; }, function(error) { return Promise.reject(error); }); // 响应拦截器 axios.interceptors.response.use(function(response) { // debugger; // var jwt = response.headers['jwt']; // if(jwt){ // window.vm.$store.commit('setJwt',{jwt:jwt}); // } return response; }, function(error) { return Promise.reject(error); }); // // 路由请求拦截 // // http request 拦截器 // axios.interceptors.request.use( // config => { // //config.data = JSON.stringify(config.data); // //config.headers['Content-Type'] = 'application/json;charset=UTF-8'; // //config.headers['Token'] = 'abcxyz'; // //判断是否存在ticket，如果存在的话，则每个http header都加上ticket // // if (cookie.get("token")) { // // //用户每次操作，都将cookie设置成2小时 // // cookie.set("token", cookie.get("token"), 1 / 12) // // cookie.set("name", cookie.get("name"), 1 / 12) // // config.headers.token = cookie.get("token"); // // config.headers.name = cookie.get("name"); // // } // return config; // }, // error => { // return Promise.reject(error.response); // }); // // 路由响应拦截 // // http response 拦截器 // axios.interceptors.response.use( // response => { // if (response.data.resultCode == "404") { // console.log("response.data.resultCode是404") // // 返回 错误代码-1 清除ticket信息并跳转到登录页面 // // cookie.del("ticket") // // window.location.href='http://login.com' // return // } else { // return response; // } // }, // error => { // return Promise.reject(error.response) // 返回接口返回的错误信息 // }); export default axios;
4.5.3.修改main.js配置vue-axios
在main.js文件中引入api模块和vue-axios模块
import axios from '@/api/http' import VueAxios from 'vue-axios' Vue.use(VueAxios,axios)
4.5.4.使用封装后的axios发送请求
从Login.vue组件中移除导入的axios和qs模块
#import axios from 'axios' #import qs from 'qs'
使用全局的axios发送请求
let url=this.axios.urls.SYSTEM_USER_DOLOGIN; this.axios.post(url,params).then(function(response) { console.log(response); }).catch(function(error) { console.log(error); });
效果和前面一样
PS: 跨域问题
**解决方案：**需要配置tomcat允许跨域访问，tomcat跨域配置方法很多，但最简单的方式是自己写一个过滤器CorsFilter实现，添加一个响应头Access-Control-Allow-Origin即可：
httpResponse.addHeader("Access-Control-Allow-Origin", "*");//*表示任何域名 httpResponse.addHeader("Access-Control-Allow-Origin", "http://localhost:80"); Access-Control-Allow-Origin:* #则允许所有域名的脚本访问该资源。 Access-Control-Allow-Origin:https://www.fujieace.com #允许特定的域名访问
