一、创建项目集成element-ui

软件版本

  • jdk 1.8
  • mysql5.7+
  • node14.16.0
  • navicat
  • idea2021.3

下载地址：毕设软件 - 坚果云 - 云盘|网盘|企业网盘|同步|备份|无限空间|免费网络硬盘|企业云盘

vue-cli安装：npm install -g @vue/cli

npm设置淘宝镜像加速：npm config set registry https://registry.npm.taobao.org

创建vue项目：vue create vue

运行vue项目：

cd vue

npm run serve

安装ElementUI：

npm i element-ui -S 

集成element-ui

main.js

import Vue from 'vue'
import App from './App.vue'
import router from './router'
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
import './assets/gloable.css'

Vue.config.productionTip = false

Vue.use(ElementUI,{size:"mini"});

new Vue({
  router,
  render: h => h(App)
}).$mount('#app')

 二、主体框架搭建

App.vue

<template>
  <div id="app">
    <router-view/>
  </div>
</template>


<style>
  #app{
    height: 100vh;
  }
</style>

gloable.css

*{
    margin: 0;
    padding: 0;
    box-sizing: border-box;
}

.ml-5{
    margin-left: 5px;
}
.mr-5{
    margin-right: 5px;
}
.pd-10{
    padding:10px 0 ;
}

main.js

import './assets/gloable.css'

菜单栏收缩实现：

<el-menu :default-openeds="['1', '3']" style="height: 100%"
                     background-color="rgb(48,65,86)"
                     text-color="#fff"
                     active-text-color="#ffd04b"
                     :collapse-transition="false"
                     :collapse="isCollapse"
            >
<div style="height: 60px;line-height: 60px; text-align: center">
                    <img src="../assets/logo.png" alt=""

                    <b style="color: white" v-show="logoTextShow">后台管理系统</b>

<el-header style="font-size: 12px;border-bottom: 1px solid #ccc; line-height: 60px; display: flex">
