适用于vue3的vue-router的404配置

老版本(适用于vue2的vue-router)

在所有路由的最后配置

{
    path: '*',
    name: '404',
    component: () => import('@/pages/404')
}

新版本(适用于vue3的vue-router)

{
    path: '/404',
    name: '404',
    component: () => import('@/pages/404')
},
{
    path: '/:pathMatch(.*)',
    redirect: '/404'
}

import { RouteRecordRaw } from 'vue-router'
import LoginPage from 'pages/LoginPage.vue'
import BasicLayout from 'layouts/BasicLayout.vue'
import { LOGIN_ROUTE_NAME } from 'utils/SystemConstants'


const component404 = import('pages/Page404.vue')
