根据读卡器读卡结果，然后判断，渲染不同的组件，是用动态组件好还是用路由好？

1、路由实现的话，自动跳转是写在组件内还是写在路由文件的钩子函数内，应该怎么改我以下代码？

export default new Router({
    mode: 'history',
    routes: [
        {
            path: '/index',
            name: 'index',
            component: index
        },
        {
            path: '/loading',
            name: 'loading',
            component: loading
        },
        {
            path: '/success',
            name: 'success',
            component: success
        },
        {
            path: '/carry',
            name: 'carry',
            component: carry
        },
        {
            path: '/interrupt',
            name: 'interrupt',
            component: interrupt
        },
        {
            path: '/error',
            name: 'error',
            component: error
        },
        {
            path: '/',
            name: 'allowance',
            component: allowance
        }
    ]
});

2、动态组件如何实现希望老师能给个超小的例子。
