3.多级路由（多级路由）

  1. 配置路由规则，使用children配置项：

    routes:[
	{
		path:'/about',
		component:About,
	},
	{
		path:'/home',
		component:Home,
		children:[ //通过children配置子级路由
			{
				path:'news', //此处一定不要写：/news
				component:News
			},
			{
				path:'message',//此处一定不要写：/message
				component:Message
			}
		]
	}
]

  2. 跳转（要写完整路径）：

    <router-link to="/home/news">News</router-link>
