一，ElementUI是什么？
? ? ? ? ? ? ? Element UI 是一個基于 Vue.js 的桌面端組件庫，它提供了一套豐富的 UI 組件，用于構(gòu)建用戶界面。Element UI 的目標(biāo)是提供簡潔、易用、美觀的組件，同時保持靈活性和可定制性
二，ElementUI的特點與功能(大致五點)
Element UI 的特點和功能包括：
豐富的組件：
? ? ? ? ? ?Element UI 提供了大量的常用組件，包括按鈕、表單、表格、對話框、菜單等等。這些組件經(jīng)過精心設(shè)計，具有統(tǒng)一的風(fēng)格和交互體驗，在構(gòu)建用戶界面時非常方便。
響應(yīng)式布局：
? ? ? ? Element UI 的組件可以自動適應(yīng)不同屏幕尺寸，支持響應(yīng)式布局，使得應(yīng)用程序在不同設(shè)備上都有良好的顯示效果。
簡潔易用：
? ? ?Element UI 的組件設(shè)計簡潔，提供了豐富的配置選項，開發(fā)者可以通過參數(shù)的方式靈活地定制組件的外觀和行為。
??主題定制：
? ? ?Element UI 提供了一套默認的主題樣式，但也支持自定義主題。你可以根據(jù)項目的需求定制自己的主題樣式，以使應(yīng)用程序更符合項目的整體風(fēng)格
國際化支持：
? ?Element UI 內(nèi)置了多語言支持，可以方便地實現(xiàn)多語言應(yīng)用程序
二，Element搭建登入注冊前期準備
①搭建SPA項目? ?
沒有搭建SPA項目---》》點擊進入SPA項目搭建流程
②導(dǎo)入Element依賴
使用命令npm install element-ui -S，添加Element-UI模塊
注意：要在你的SPA項目工作區(qū)間下使用cmd終端命令下載（如下）
下載完畢之后在你的SPA項目下的package.json文件中會看見下載所需要的Element依賴
三，Element實現(xiàn)登入注冊界面?
第一步：在src目錄下創(chuàng)建views目錄（該目錄用于存放vue組件）
第二步：在main.js中引入element-ui模塊
在項目中src目錄下找到
main.js，并在指定位置添加三行代碼：注意：要在import App from './App'這行代碼前面添加下面三行代碼
import Vue from 'vue'// 新添加1 import ElementUI from 'element-ui' // 新添加2，避免后期打包樣式不同，要放在import App from './App';之前 import 'element-ui/lib/theme-chalk/index.css'Vue.jsx掛載Element代碼（也是在
main.js文件下添加即可）:Vue.use(ElementUI) Vue.config.productionTip = false第三步：①創(chuàng)建用戶登錄組件
Login.vue<template><div class="login-wrap"><el-form class="login-container"><h1 class="title">用戶登錄</h1><el-form-item label=""><el-input type="text" v-model="username" placeholder="登錄賬號" autocomplete="off"></el-input></el-form-item><el-form-item label=""><el-input type="password" v-model="password" placeholder="登錄密碼" 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">忘記密碼</el-link><el-link type="primary" @click="gotoRegister()">用戶注冊</el-link></el-row></el-form></div> </template>為了樣式更加好看導(dǎo)入App.vue中的樣式
App.vue樣式：
<style> html, body {width: 100%;height: 100%;box-sizing: border-box;padding: 0px;margin: 0px; } #app {font-family: "Avenir", Helvetica, Arial, sans-serif;-webkit-font-smoothing: antialiased;-moz-osx-font-smoothing: grayscale;color: #2c3e50;widows: 100%;height: 100%; } </style>login.vue與Register.vue樣式：
<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"?>

四，數(shù)據(jù)交互
使用SSM項目構(gòu)建Java后臺，模擬提供一個用戶登錄的action地址，Vue通過請求指定的用戶登錄接口。
4.1 了解axios與安裝
axios是vue2提倡使用的輕量版的ajax。它是基于promise的HTTP庫。它會從瀏覽器中創(chuàng)建XMLHttpRequests，與Vue配合使用非常好。
題外話：vue.js有著名的全家桶系列：vue-router，vuex， vue-resource，再加上構(gòu)建工具vue-cli，就是一個完整的vue項目的核心構(gòu)成。 其中vue-resource是Vue.js的一款插件，它可以通過XMLHttpRequest或JSONP發(fā)起請求并處理響應(yīng)，但在vue更新到2.0之后，作者就宣告不再對vue-resource更新，而是推薦的axios
安裝語法：
npm i axios -S
默認為post請求
如果數(shù)據(jù)交互需要get請求要下載有關(guān)get請求的的依賴
get語法：
npm i qs -S
注意：要在你的SPA項目工作區(qū)間，啟動cmd窗口，執(zhí)行該行代碼（如下）
4.2 axios之Post請求
1 在前端導(dǎo)入剛下載好的axios依賴
import axios from 'axios'前端編寫：
<script> import axios from 'axios' export default {name: 'Login',data () {return {username:'',password:''}} ,methods:{gotoRegister(){this.$router.push('/Register'); },doSubmit(){let url= 'localhost:8080/ssm/user/userLogin';let params = {username:this.username,password:this.password}axios.get(url,{params:params}).then(r=>{console.log(r);if(r.data.success){this.$message({message:r.data.msg,type:'success'});}else{this.$message.error(r.data.msg); }}).catch(e=>{})}} } </script>接下來將前端中index.js下的修改SPA項目的端口號，以防萬一與后端端口號一致
在我們的后端項目中，有一個視圖解析器來處理我們前端發(fā)過來的請求進行處理
userController:
package com.zking.ssm.controller;import com.zking.ssm.service.IUserService; import com.zking.ssm.util.JsonResponseBody; import com.zking.ssm.util.PageBean; import com.zking.ssm.vo.UserVo; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody;import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.util.HashMap; import java.util.List; import java.util.Map; import com.zking.ssm.jwt.*;@Controller @RequestMapping("/user") public class UserController {@Autowiredprivate IUserService userService;@RequestMapping("/userLogin")@ResponseBodypublic JsonResponseBody<?> userLogin(UserVo userVo, HttpServletResponse response){if(userVo.getUsername().equals("admin")&&userVo.getPassword().equals("123")){//私有要求claim // Map<String,Object> json=new HashMap<String,Object>(); // json.put("username", userVo.getUsername());//生成JWT，并設(shè)置到response響應(yīng)頭中 // String jwt=JwtUtils.createJwt(json, JwtUtils.JWT_WEB_TTL); // response.setHeader(JwtUtils.JWT_HEADER_KEY, jwt);return new JsonResponseBody<>("用戶登陸成功！",true,0,null);}else{return new JsonResponseBody<>("用戶名或密碼錯誤！",false,0,null);}}@RequestMapping("/queryUserPager")@ResponseBodypublic JsonResponseBody<List<Map<String,Object>>>queryUserPager(UserVo userVo, HttpServletRequest request){try {PageBean pageBean=new PageBean();pageBean.setRequest(request);List<Map<String, Object>> users = userService.queryUserPager(userVo, pageBean);return new JsonResponseBody<>("OK",true,pageBean.getTotal(),users);} catch (Exception e) {e.printStackTrace();return new JsonResponseBody<>("分頁查詢用戶信息失敗！",false,0,null);}} }在前端項目工作區(qū)間下，文件路徑輸入cmd，打開cmd窗口。
輸入命令開啟項目 :?
npm run dev
并且在后端啟動maven項目，可以進行訪問才可

import axios from '@/api/http' import VueAxios from 'vue-axios' Vue.use(VueAxios,axios)
五，注冊功能實現(xiàn)?
①自行創(chuàng)建一個注冊頁面
②定義接口、接口實現(xiàn)類
接口類：
int insertSelective(User record);實現(xiàn)接口類：
@Overridepublic int insertSelective(User record) {return userMapper.insertSelective(record);}③ Controller層編寫：
@RequestMapping("/userRegister")@ResponseBodypublic JsonResponseBody<?> userRegister(UserVo userVo, HttpServletResponse response) {//狀態(tài)新注冊默認為0userVo.setStatus("0");//因為ID為String類型需要手動設(shè)置，當(dāng)然可以根據(jù)自己的需要改為Int類型userVo.setId("9");int i = userService.insertSelective(userVo);if (i > 0) {return new JsonResponseBody<>("用戶注冊完成！快去登入吧！", true, 0, null);} else {return new JsonResponseBody<>("用戶注冊失敗！重新輸入。", false, 0, null);}}
五，跨域問題?
5.1 概念
? ? ? 跨域問題（Cross-Origin Resource Sharing，CORS）指的是在瀏覽器端，由于安全策略限制，不同源（域/協(xié)議/端口）之間的網(wǎng)頁（或者Ajax請求）無法直接進行交互或訪問對方的資源。同源策略是瀏覽器的一種安全機制，用于保護用戶信息和防止惡意攻擊。
? 同源策略要求網(wǎng)頁只能與相同源的資源進行交互，源（Origin）由協(xié)議、域名和端口號組成。當(dāng)源不一致時，瀏覽器會阻止跨域的請求。例如，一個網(wǎng)頁在域A中運行，試圖通過JavaScript向域B發(fā)送AJAX請求，此時就會觸發(fā)跨域問題
5.2 解決跨域問題
web.xml:
<!--CrosFilter跨域過濾器--><filter><filter-name>corsFilter</filter-name><filter-class>com.zking.ssm.util.CorsFilter2</filter-class></filter><filter-mapping><filter-name>corsFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping>跨域工具類:
CorsFilter2? 過濾器
這段代碼的作用是配置Tomcat服務(wù)器允許來自任何域名的跨域訪問，并允許客戶端發(fā)送包含指定請求頭的請求，以及指定允許的請求方法
package com.zking.ssm.controller;import java.io.IOException;import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletResponse;/*** 配置tomcat允許跨域訪問* * @author Administrator**/
public class CorsFilter2 implements Filter {@Overridepublic void init(FilterConfig filterConfig) throws ServletException {}@Overridepublic void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain)throws IOException, ServletException {HttpServletResponse httpResponse = (HttpServletResponse) servletResponse;// Access-Control-Allow-Origin就是我們需要設(shè)置的域名// Access-Control-Allow-Headers跨域允許包含的頭。// Access-Control-Allow-Methods是允許的請求方式httpResponse.setHeader("Access-Control-Allow-Origin", "*");// *,任何域名httpResponse.setHeader("Access-Control-Allow-Headers", "responseType,Origin, X-Requested-With, Content-Type, Accept");httpResponse.setHeader("Access-Control-Allow-Methods", "POST, GET, PUT, DELETE");//允許客戶端處理一個新的響應(yīng)頭jwt//httpResponse.setHeader("Access-Control-Expose-Headers", "jwt,Content-Disposition");filterChain.doFilter(servletRequest, servletResponse);}@Overridepublic void destroy() {}
}
