1. 配置路由缓存

component: () => import('views/entrance/index')
    }, {
      path: '/seniorList',
      name: 'list',
      title: '高级查询列表',
      meta: {
        secTitle: '高级查询列表',
        keepAlive: true
      },
      component: () => import('views/entrance/seniorList')
    }, {
      path: '/list',
      name: 'list',
      title: '普通查询列表',

      meta: {
        secTitle: '普通查询列表',
        keepAlive: true
      },

其中对应配置为 keepAlive: true

2. 配置App.vue文件 router-view

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

3.用户返回时使用this.$router.back()返回

当用户点击返回时，将 this.router.go(-1)改成this.router.back()，不然不生效。
