解决Vue中使用keepAlive不缓存问题

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

{
 path:'/loanmessage',
 component:loanmessage,
 name:'loanmessage',
 meta: {
  keepAlive: true, //代表需要缓存
  isBack: false,
 },

beforeRouteEnter(to, from, next) {
 if (from.name == 'creditInformation' || from.name == 'cityList') {
  to.meta.isBack = true;
 }
 next();
},
activated() {
 this.getData()
 this.$route.meta.isBack = false
 this.isFirstEnter = false
 
},
