单个 <router-view/> 和多个 <router-view/> 的区别，
单个 <router-view/> 只是一个区域的变化，不需要设置name属性，在设置路由的时候单个<router-view/>使用的是component，
多个<router-view/>里面需要设置一个name属性，设置路由的时候单个<router-view/>使用的是components，
————————————————
<div>
<router-view/>
<router-view class="left" name="nav" />
<router-view class="right" name="con" />
</div>
然后在router.js中进行配置，注意：component改成要components，components是一个对象了，nav:AboutNav,左侧的nav就是<router-view name="nav" /> 标签里的 name属性值，nav:AboutNav,右侧的AboutNav就是引用组件时候import AboutNav from './views/AboutNav.vue'中的AboutNav。
import AboutCon from './views/AboutCon.vue'
import AboutNav from './views/AboutNav.vue'
{
path: '/about',
name: 'about',
components:
{
nav:AboutNav,
con:AboutCon
}
}
--------------------
other
vue同一个页面可以有多个router-view
参考：https://blog.csdn.net/u011615787/article/details/80075240
分别给router-view定义一个name，默认显示的可以不用定义
自己先在components文件夹内写4个组件，准备放入4个router-viewer标签，我的分别是
app.vue

运行效果如图：
