解决react 路由切换，页面闪屏的bug

在router目录中添加如下配置

复制代码
// // 配置路由信息
import {Navigate } from "react-router-dom"
import {lazy,Component, Suspense } from "react"
import { JSX } from 'react/jsx-runtime'


// 懒加载模式需要使用loding
const Layout=lazy(()=>import("@/layout/index"))

const Home = lazy(()=>(import("@/pages/home")))
const Page404=lazy(()=>(import("@/pages/404/index")))

// 设置
const Systemset = lazy(()=>(import("@/pages/systemSet/index")))
const Citytree = lazy(()=>(import("@/pages/systemSet/cityTree/index")))
// 登录
const Login=lazy(()=>import("@/pages/login/index"))

// 充电桩管理
const ChargManage=lazy(()=>(import("@/pages/chargingManagement/index")))
// 充电站管理
const ChargMangeList=lazy(()=>import("@/pages/chargingManagement/list/index"))
// 添加充电站
const AddChargingStation=lazy(()=>import("@/pages/chargingManagement/list/addCharging"))
// 充电桩
const ChargStation=lazy(()=>import("@/pages/chargingManagement/chargingStation/index"))
// 添加充电桩
const AddChargStation=lazy(()=>import("@/pages/chargingManagement/chargingStation/addCharging"))
// vr信息
const Vrfile=lazy(()=>import("@/pages/chargingManagement/vrFile/index"))
// 评价
const Evaluate=lazy(()=>import("@/pages/chargingManagement/evaluate/index"))
// 用户管理
const User=lazy(()=>import("@/pages/user/index"))
const UserList=lazy(()=>import("@/pages/user/list/index"))

// <Suspense>占位组件
/*当懒加载组件还没有加载出来的时候，先用占位组件显示。里面有一个属性fallback，
里面传进去的组件就是占位组件。有<Suspense>表示该组件懒加载出来的，决定是否懒加载出来的看是不是React.lazy().*/
const withLoading=(somp:JSX.Element)=>(
    <Suspense fallback={<div>加载中...</div>}>
           {somp}
        </Suspense>
)

使用懒加载lazy（）添加路由
Suspense 懒加载组件在加载不出来的时候显示的内容
需要再每层的路由配置中添加不然就会闪屏
