多级路由component页面不加载

项目基于vue-element-admin

1. 新建SubView.vue

   <template>
     <router-view />
   </template>
   
   <script setup>
   </script>
   

2. 在父层添加component

   {
       path: '/sj',
       component: Layout,
       redirect: '/sj',
       name: '三级医院评审标准(2022)',
       meta: {
         title: '三级医院评审标准(2022)'
       },
       children: [
         {
           path: '/b1',
           meta: {
             title: '医疗服务能力与医院质量安全'
           },
           component: () => import('@/layout/components/SubView.vue'),//父层添加该行
           children: [
             {
               path: '/c1',
               meta: {
                 title: '医疗服务能力'
               },
               component: () => import('@/layout/components/SubView.vue'),//父层添加该行
               children: [
                 {
                   path: '收治病种数量',
                   component: () => import('@/views/116query/zip-code'),
                   name: '收治病种数量',
                   meta: { title: '收治病种数量', affix: true }
                 },
                 ...
