//在router文件加上meta判断

import Vue from 'vue'

import Router from 'vue-router'

Vue.use(Router)

export default new Router({

    {//home会被缓存

        path:"/home",

        component:home,

        meta:{keepAlive: true}

    }

    {//hello不会被缓存

        path:"/hello",

        component:hello,

        meta:{keepAlive: false}

    }

})
第二种

// 组件

export default {

  name: 'test-keep-alive',

  data () {

    return {

        includedComponents: "test-keep-alive"

    }

  }

}

<keep-alive include="test-keep-alive">

  <!-- 将缓存name为test-keep-alive的组件 -->

  <component></component>

</keep-alive>

<keep-alive exclude="test-keep-alive"> <!-- 将不缓存name为test-keep-alive的组件 --> <component></component> </keep-alive>
