Vue生命周期踩坑activated和keep-alive

当页面应用了keep-alive，那么进入这个页面和离开这个页面都只走生命周期activated,其余不走。

beforeCreate(){
    console.log("beforeCreate");
  },
  created(){
    console.log("created");
  },
  activated(){
    console.log("activated");  //下次进入页面，只打印出activatd
  },
  activitty(){
    console.log("activit");
  },
  mounted() {
    console.log(666);
  },
  beforeDestroyed() {
    console.log(666);
  },
