main.js

import Vue from 'vue'
import App from './App.vue'
//全部引入

import {Button, Radio, Select, Container, Aside, Header, Main, Menu, MenuItem, MenuItemGroup, Submenu} from 'element-ui';
import router from './router.js'


Vue.component(Select.name, Select);
Vue.component(Radio.name, Radio);
Vue.use(Button)

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

侧边栏组件
CommonAside.vue

<template>
  <!--    default-active  默认展开项目-->
  <el-menu
      class="el-menu-vertical-demo"
      @open="handleOpen"
      @close="handleClose"
      background-color="#545c64"
      text-color="#fff"
      active-text-color="#ffd04b"
      :collapse="isCollapse">
    <h3>通用后台管理系统</h3>
    <el-menu-item :index="item.path" v-for="item in noChildren " :key=item.path @click="clickMenu(item)">
      <i :class="'el-icon-'+item.icon"></i>
      <span slot="title">{{ item.label }}</span>
    </el-menu-item>

    <el-submenu :index="item.label" v-for="item in hasChildren" :key=item.path>
      <template slot="title">
        <i :class="'el-icon-'+item.icon"></i>
        <span slot="title">{{ item.label }}</span>
      </template>
      <el-menu-item-group>
        <el-menu-item :index="subItem.path" v-for="(subItem,subIndex) in item.children" :key="subIndex"
                      @click="clickMenu(item)">
          <i :class="'el-icon-'+subItem.icon"></i>
          <span slot="title">{{ subItem.label }}</span>
        </el-menu-item>
      </el-menu-item-group>

    </el-submenu>
  </el-menu>
</template>

<style lang="scss" scoped>

.el-menu {
  height: 100%;
  border: none;

  h3 {
    color: #ffffff;
    text-align: center;
    line-height: 48px;
  }
}

.el-menu-vertical-demo:not(.el-menu--collapse) {
  width: 200px;
  min-height: 400px;
}

</style>


<script>

export default {
  name: "CommonAside",
  data() {
    return {
      //展开 还是折叠
      isCollapse: false,
      menu: [
        {path: "/", name: "home", label: "首页", icon: "s-home", url: "Home/Home"},
        {path: "/mall", name: "mall", label: "商品管理", icon: "video-play", url: "MallManage/MallManage"},
        {path: "/user", name: "user", label: "用户管理", icon: "user", url: "UserManage/UserManage"},
        {
          label: "其他",
          icon: "location",
          children: [
            {path: "/page1", name: "page1", label: "页面1", icon: "setting", url: "Other/PageOne"},
            {path: "/page2", name: "page2", label: "页面2", icon: "setting", url: "Other/PageTwo"},
          ]
        },
      ]
    };
  },
  methods: {
    handleOpen(key, keyPath) {
      console.log(key, keyPath);
    },
    handleClose(key, keyPath) {
      console.log(key, keyPath);
    },
    clickMenu(item) {
      this.$router.push({name: item.name});
    }
  },
  computed: {
    noChildren() {
      return this.menu.filter((item) => !item.children);
    },
    hasChildren() {
      return this.menu.filter((item) => item.children);
    }
  }
}
</script>

main.vue组装到上面

<template>
  <el-container style="height: 100%">
    <el-aside width="auto">
      <common-aside></common-aside>
    </el-aside>
    <el-container>
      <el-header>Header</el-header>
      <el-main>Main</el-main>
    </el-container>
  </el-container>

</template>

<script>
import CommonAside from '../components/CommonAside.vue'

export default {
  name: "Main",
  components: {CommonAside}
}
</script>
<style lang="scss" scoped>


.el-header {
  background: #333;
}

.el-main {
  padding-top: 0;
}
</style>

main.vue是通过router.js配置上去的

import Vue from 'vue'
import VueRouter from 'vue-router'
//自定义页面
import Main from './views/Main.vue'
//安装路由到vue
Vue.use(VueRouter)

const routes = [
    {path: '/', name: 'Main', component: Main},
    //路由的懒加载
    {path: '/about', name: 'About', component: () => import( './views/About.vue')},
]

const router = new VueRouter({
    //模式
    mode: 'history',
    base: process.env.BASE_URL,
    routes
})

export default router

App.vue就很简单了

<template>
    <router-view/>
</template>

<script>
export default {
  data() {
    return {
      radio: '1'
    };
  }
}

</script>

<style>
#app {
  font-family: Avenir, Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin: 0;
}
</style>

有点难以搞懂的bug需要配置这里一个样式 否则达不到预期效果

<style>

    body {
        margin: 0;
    }

    html, body {
        height: 100%;
    }
</style>
