通过key决定是否刷新keep-alive组件的方法

 <keep-alive>
            <router-view :key="checkKeepAlive()"></router-view>
          </keep-alive>

checkKeepAlive() {
      if (!this.$route.meta.keepAlive) {
        console.log(‘输出‘,this.$route.name)
        return this.$route.name+Math.random();
      }
    }

 children: [
      {
        path: "/home/test1",
        name: "test1",
        meta: {
          keepAlive: true
        },
        component: () => import("@/components/Test1.vue")
      },
      {
        path: "/home/test2",
        name: "test2",
        meta: {
          keepAlive: false
        },
        component: () => import("@/components/Test2.vue")
      }
    ]
