?生命周期執(zhí)行順序：

1、不使用keep-alive的情況：beforeRouteEnter --> created --> mounted --> destroyed

2、使用keep-alive的情況：beforeRouteEnter --> created --> mounted --> activated --> deactivated

3、使用keep-alive，并且再次進(jìn)入了緩存頁面的情況：beforeRouteEnter -->activated --> deactivated

在keep-alive頁面里的activated 監(jiān)聽路由的參數(shù)變化可以實現(xiàn)全頁面刷新，
