一、拆分
新建包：
Aside和Header都是组件
User为视图
Aside.vue：
<template><el-menu :default-openeds="['1', '3']" style="min-height: 100%; overflow-x: hidden"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="" style="width: 20px; position: relative; top: 5px; right: 5px"><b style="color: white" v-show="logoTextShow">后台管理系统</b></div><el-menu-item index="/"><template slot="title"><i class="el-icon-s-home"></i><span slot="title">主页</span></template></el-menu-item><el-submenu index="2"><template slot="title"><i class="el-icon-menu"></i><span slot="title">系统管理</span></template><el-menu-item index="/user"><template slot="title"><i class="el-icon-user"></i><span slot="title">用户管理</span></template></el-menu-item></el-submenu></el-menu>
</template><script>

</script><style scoped></style>Head.vue
<template><div style="font-size: 12px;line-height: 60px; display: flex"><div style="flex: 1;"><span :class="collapseBtnClass" style="cursor: pointer; font-size: 18px" @click="collapse"></span><el-breadcrumb separator="/" style="display: inline-block;margin-left: 10px" ><el-breadcrumb-item :to="item.paths" :key v-for="item in paths">{{ item.name }}</el-breadcrumb-item></el-breadcrumb></div><el-dropdown style="width: 70px; cursor: pointer"><span>王小虎</span><i class="el-icon-arrow-down" style="margin-left: 5px"></i><el-dropdown-menu slot="dropdown"><el-dropdown-item style="font-size: 14px; padding: 5px 0">个人信息</el-dropdown-item><el-dropdown-item style="font-size: 14px; padding: 5px 0">退出</el-dropdown-item></el-dropdown-menu></el-dropdown></div>
</template><script>
export default {name: "Header",props:{collapseBtnClass: String,collapse:Function},data(){return{paths:[]}},
}
</script><style scoped></style>User.vue

调用拆分的视图及组件
视图：使用router-view调用
组件：导入组件包:
//导入
import Aside from "@/components/Aside.vue";
import Header from "@/components/Header.vue";
创建组件包含内容
//调用组件components: {Aside,Header,},调用组件：
