可以在路由meta中加入参数, 对打开的路由进行keep-alive的判断, 通过钩子active等

设置缓存：

<keep-alive>
      <router-view v-if="$route.meta.keepAlive" />
</keep-alive>
<router-view v-if="!$route.meta.keepAlive" />

更新当前组件，设置不同:key键;activated中更新数据;

1.通过keep-alive组件可以缓存 组件,通过路由配置中的meta选项中的自定义属性trueorfalse决定缓存,或者使用include属性来添加缓存的组件
2.key值的改变组件会进行重建,因此可以再actived中改变key值
